       [0001]    This is a Non-Provisional application of U.S. Provisional Application No. 62/210,351, filed in the United States on Aug. 26, 2015, entitled, “MOTORIZED SKATEBOARD,” which is incorporated herein by reference in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    (1) Field of the Invention 
         [0003]    This invention relates to motorized and non-motorized skateboards, treaded skateboards, and in particular, to motorized and non-motorized skateboards, treaded skateboards, and treaded skateboards that use single wheels mounted on fork arm trucks. Furthermore, this invention relates to fork arm systems that use motorized wheels, both externally mounted to the skateboards, and more specifically, relates to internally mounted motors within the wheels. This invention also relates to new wheel designs for single wheel skateboard applications, and a new complementary riding system that incorporates magnetic coupling to skateboards and to skateboard shoes. 
         [0004]    (2) Description of Related Art 
         [0005]    Conventional skateboards have provided excitement over the years and are deemed a right of passage for young people. Along with bicycles and scooters, skateboards are playing a large role in increasing youth mobility. A new paradigm of travel is evolving as skateboards become motorized. 
         [0006]    The problem with the current skateboard four-wheel system is that it is comprised of four wheels. Two wheels on each axis separated by 7 to 10 inches in a common skateboard hanger system. Riding a skateboard that has four wheels, even though they are on independent trucks, subjects the rider to a bumpy ride. 
         [0007]    Skateboard parks are not always available to all skateboard enthusiasts. Often, skateboarders are performing tricks and enhancing their skills in places where they may not be welcomed. Performing tricks with skateboards that involve public structures, such as stairs, planters, railings, and curbs, can be destructive to the community property, as well as, being dangerous to the skateboarder and others in the area. This damage is caused by the action of grinding. These tricks often use the aluminum or steel skateboard hanger undersides to skid on the surfaces previously mentioned. To mitigate the effects of this grinding, Teflon® and other resilient materials have been added to the undercarriage of the skateboard to minimize the effects of grinding away the skateboard components and damaging public property. It is the intent of this disclosure to solve the problem for the community property damage and enhance the performance and safety of the skateboarder by introducing new skateboard wheel geometries for the single wheel truck skateboard. 
         [0008]    Skateboard parks and half pipe gatherings are events where the skateboarders exhibit their coordination and mastery of riding skateboards. Some of the maneuvers performed by the skateboarders, such as 360°, 720° and 1080° turns, are quite dangerous. Injuries occur when the skateboard riders&#39; feet separate from the skateboard. Often these injuries occur when in the crouched position, holding the skateboard deck to the skateboard riders&#39; feet. These maneuvers place skateboarders in precarious positions that can result in injury. It is the intent of this novel invention to introduce the use of the magnetic shoe and skateboard deck skin coupling system to help improve skateboarders&#39; performance and safety. 
         [0009]    With new manufacturing processes and composite materials, skateboard production has been revolutionized. Along with the introduction of highly efficient electric motors, and substantially improved lithium-ion and lithium phosphate batteries, the popularity of using skateboards for transportation is expanding. 
         [0010]    As a result of these advancements, certain skateboard motor assemblies have the components exposed to the elements and can interfere with the skateboarders&#39; ability to maneuver. Additionally, it is difficult to streamline the four-wheeled skateboard when adding heavy drive train accessories such as belts, pulleys and chains. It is the intent of this invention to eliminate the concerns by integrating the motors inside the wheels. 
         [0011]    The current skateboard is a four-wheel system with two wheels on each axis separated by 7 to 10 inches in a common skateboard hanger system configuration. Although each set of wheels is on an independent truck, the ride is bumpy. Four-wheel skateboards are limited to smooth compact surfaces for riding. The proposed invention will increase the rider&#39;s access to grass, sand, snow, ice, and mud with the treaded skateboard and/or the large wheel skateboard. 
         [0012]    Another application of this invention is the treaded cooler, which provides ease of use and comfort in any environment and can easily be managed by one person. Consider any situation that would involve the use of large two or four-wheel coolers, from emergency response events to pleasure/sport activities. The large two wheeled coolers are difficult to lift, pull or place without involving vehicle logistics and additional manpower. Such efforts can result in physical injuries to those using this type of cooler. 
         [0013]    The cooler wheels do not traverse on uneven or soft surfaces, which require the cooler to be picked up and carried across these surfaces. The coolers are heavy and bulky in size, which can be challenging to carry over or pull on rough or soft surfaces. 
         [0014]    Conventional coolers are not constructed to provide stable seating for small children or to caravan multiple coolers. Consequently, transporting coolers, children and other accessories to the designated location may involve multiple trips. 
         [0015]    It is the intent of this invention to demonstrate another application of the fork truck and wheel combinations that can be applied to a recreational cooler, which will provide ease of use, manageability by one person, provide transport for small children and caravan multiple coolers to the point of destination. 
       SUMMARY OF INVENTION 
       [0016]    The single-wheel fork system design versus the conventional two-wheel skateboard truck system provides the rider with smooth nondestructive wheels, stability control on slanted surfaces, and increased speed by eliminating the grinding of the aluminum or metal structure of the skateboard trucks on the concrete or brick planter edges. The novel invention addresses the stability and smoothness of the skateboard ride by creating a single-wheel fork truck system, which consists of one single-wheel fork truck system in the front and another in the rear. 
         [0017]    This novel invention also incorporates the motor drive system into the wheel or wheel hub. This invention can convert a conventional skateboard into a motorized version by installing motors into any one of the four wheels. However, the preferred embodiment of this novel invention is to use two wheels, which is the single-wheel fork truck system. 
         [0018]    To produce the two-wheel motorized and non-motorized skateboard, this invention introduces the skateboard transom fork hanger. This novel skateboard transom fork hanger assembly holds the wheel on the inside of the skateboard hanger. Conventional skateboard hangers put the skateboard wheels on the outside of the hanger. The uniqueness of the invention is to use the skateboard transom fork hanger assembly to hold a motorized wheel assembly by the inside of the forks. This system design increases maneuverability, stability, and smoothness of the ride. 
         [0019]    Another advantage of the novel invention is the flexibility for designing small non-motorized single-wheel fork truck skateboards. Descriptions of different skateboard wheels in this invention, and as part of the invention, reveals how important the skateboard transom fork hanger assembly is in developing new skateboard media. This invention also describes how to motorize even the small wheel skateboard by coupling an externally mounted motor to the underside of the skateboard single-wheel transom fork hanger assembly. 
         [0020]    Normally, a skateboard has two wheels in the front and two wheels in the back of a skateboard deck. They establish a wide riding plane. This plane alternates between infinite numbers of planes as the skateboard trucks wobble when in motion. Even on smooth sidewalks on a diagonal angle, the rider will feel the crack in the sidewalk four times as skateboard rides across. A rider on a two-wheel skateboard will only experience two cracks. As elementary as this point is, it can introduce discomfort to the rider with a four-wheel skateboard. The current invention aspires to solve that problem by using two wheels. 
         [0021]    By using two wheels, one in the front and one in the back, the skateboard is riding on a wide line, as opposed to the wide plane, that continually oscillates due to the oscillation amplification of the four skateboard wheels as they encounter road imperfections and debris. The speed performance of the skateboarder is enhanced with the reduced friction on the road with the two skateboard wheels. This increases performance, comfort and safety. This novel invention will disclose the design feature of a large single wheel skateboard that can be used on grass, gravel, sand, mud, or other soft surfaces. 
         [0022]    The current invention, the motorized version of skateboards, provides a direct drive that eliminates cumbersome chains, belts and the associated gearing and harnessing that are required to implement the drivetrain on conventional skateboards. This invention introduces a novel skateboard fork transom system, which includes novel wheel designs for non-motorized skateboard systems that will enhance safety of the skateboard rider when performing tricks on public property or in skateboard parks. 
         [0023]    These designs will eliminate the need for the destructive action of grinding on park or public structures. Other surfaces become accessible to the skateboarder with the introduction of the skateboard transom system. The multiple novel wheel profiles allow for less destructive activities, and more challenging skateboard maneuvers and positive control over those maneuvers. For example, skateboarders like to use planter beds, curbs and other concrete structures that have obstruction free edges to perform “grinding” maneuvers. With these novel wheels, skateboarders will be able to ride on obstacles as though they were grinding, but with less destructive results. Grinding or riding on edges of obstacles can now be performed with wheels. Riding the rails (hand rails) or exposed pipes can be performed with specially configured wheels. 
         [0024]    Typically riding these rails involves using the center metallic portion of the skateboard truck. This is actually the bottom part of the skateboard truck, which holds the wheels. This maneuver defaces the object and degrades the skateboard truck. The present invention creates a single wheel that has a circular or straight v-groove in the center of the wheel for riding on objects. 
         [0025]    The present invention shows that the large single wheel motorized and non-motorized skateboard has a larger surface area to travel on grass, sand, and muddy surfaces. Another novelty of the invention is that a tread may be added to the wheel hubs that extend the capabilities of the skateboarding on different surfaces that aren&#39;t accessible to four-wheel skateboards. New skateboard learners will benefit significantly from the treaded skateboard. The treaded wheels can be used on grass and sand, which are safer than hard surfaces. Even the experienced skateboarder will welcome a grassy skateboard park with a downhill run. 
         [0026]    Another novel aspect of this invention is the introduction of the magnetic shoe sole and skateboard deck skin system to improve skateboarder&#39;s performance and safety. This can be employed to expand proficiency, finesse and the degree of difficulty currently attained by professionals and amateurs. The 360° maneuvers are performed more safely with the magnetic shoe and skateboard deck skin system. 
         [0027]    Such a configuration allows for positive contact of the skateboard shoe sole with the skateboard deck during the skateboard time of flight, or during execution of the trick, or performance. The skateboard trick performer does not need to crouch to the lower positions in order to grab the board and hold it to the soles of shoes as part of the trick. With the positive control of the skateboard being effected by magnetic shoes, tricks can be performed with enhanced safety and the ability to concentrate on higher degrees of rotation or other aspects of the performance. 
         [0028]    With the motorized and non-motorized versions of the skateboard transom system, the ride is greatly enhanced by the use of suspension springs that are incorporated between the transom plate and the skateboard base plate. The present invention also provides a new spring system, which can be replaced in the conventional skateboard, which are resilient leaf-like springs. 
         [0029]    The tires used for the different skateboard applications generally resemble, in the majority of cases, barrel wheel geometry with a flat section. When a rider is on the skateboard, the tire flattens to a small flat portion. This flatness, from the front wheel to the rear wheel, is significantly smaller than the area defined by the conventional four-wheel skateboard. The ride, even with the hard tire on the skateboard fork transom assembly and a single tire, is much smoother than a conventional skateboard ride. This means that it will not only be a smoother ride but a faster ride too. The skateboard transom fork hanger assembly, with whatever wheel configuration is chosen, is much easier to streamline. 
         [0030]    It is also the intent of the present invention and its components to expand the single wheel skateboard transom fork assembly to include motorcycles with two and three wheels; automobiles with two, three or four wheels; scooters in either stand-up and sit-down versions; and to include automobile applications with the main drive source (the motor) incorporated into the wheel or wheels. Also, the motors that are part of the drive mechanism of the previous skateboards, whether internal or external, may also include small gas driven reciprocating engines, turbine, compressed air driven and rotary engines. Incorporating the engines or motors into the wheel, creates more space for batteries or the fuel supply. The lighter weight is due to the reduction on the material needed for the mounting and coupling of the engine to the drivetrain. 
         [0031]    Yet another novel aspect of this invention is a configuration wherein the basic aspect is modified into a treaded cooler, which provides the opportunity for all of the weight to rest on the treads and the user pulls the treaded vehicle to the required location. The treads can be changed to address the ground conditions such as snow, water, ice, sand, gravel, and other uneven surfaces. 
         [0032]    For example, the treaded cooler can become a floating pontoon system allowing the cooler to float in water. For boaters and campers, this flexibility is easily understood. 
         [0033]    Based on the design of the optional treads, movement with the treaded cooler encounters minimal ground resistance. Changing the treads is easy and doesn&#39;t require high level of mechanical ability. The treaded cooler can be motorized; in effect, becoming a vehicle. Other additional features include attaching a seat to the cooler top for transport of a child as well as a device, which allows for attaching several coolers together to provide a caravan to carry other accessories. Side panels can be added to the cooler sides to place service items allow the top to remain free to be opened as needed. 
         [0034]    The treaded cooler moves goods with minimal effort and increases its functionality in multiple situations. No excessive lifting or pulling required with a treaded cooler, which minimizes physical injuries.

         [0202]    Please note, if used, the labels left, right, front, back, top, bottom, forward, reverse, clockwise and counter clockwise have been used for convenience purposes only and are not intended to imply any particular fixed direction. Instead, they are used to reflect relative locations and/or directions between various portions of an object. 
         [0203]    The present invention is exemplified by three principle configurations. The first of these, shown in  FIG. 1 , is a side view showing the basic components of the motorized skateboard. This view shows a typical skateboard deck  100  and a skateboard deck skin  105  that provide a good foothold for the rider. Along with the skateboard deck  100 , there are the electrical components that form the electronic assembly  107  attached to the underside of the skateboard deck  100 . Illustrated in  FIG. 1  are the transom fork hanger assembly  109  and its relation to the skateboard deck  100  and electronic assembly  107 . Attached to the skateboard transom fork hanger assembly  109  is the motorized wheel or non-motorized wheel assembly  111 . A general view of the skateboard is shown to give some perspective for the range of sizes that this invention will be addressing. 
         [0204]      FIG. 2  is an expanded isometric view of the skateboard deck  100  components and illustrates the method of attachment. The skateboard deck skin  105  is made from sandpaper-like material. There are through-holes cut into the skateboard deck skin  105 . These through-holes are  210 ,  212 , and  214 . The chamfered through-holes  230 ,  232 , and  234  in the skateboard deck  100  allow skateboard components to be fastened to it, the skateboard deck  100 . The skateboard deck skin  105  with the through-holes  210 ,  212 , and  214  allows access of the component fasteners  220 ,  222 , and  224  without removal of the skateboard deck skin  105 . The skateboard deck skin  105  is not required to have through-holes. However, assembling and reconfiguring components of the skateboard deck  100  is greatly facilitated by having the through-holes  210 ,  212 , and  214 . Component fasteners  220  pass through the chamfered through-holes  230  in the skateboard deck  100  and attach to baseplate  250  by engaging threaded-holes  240 . The next set of component fasteners are  222 , which pass through the chamfered through-holes  232  in the skateboard deck  100  and hold the battery compartments  252  by engaging threaded-holes  242 . Component fasteners  224  pass through the chamfered through-holes  234  in the skateboard deck  100 , and hold the electronic control boxes  254  by engaging threaded-holes  244 . This forms a secure and effective placement of the electronic components required for the motorized skateboard operation. 
         [0205]      FIG. 3  shows the basic electronic assembly  107  as it would be attached to the underside of the skateboard deck  100  as seen in  FIG. 2 . The battery compartment, formerly  252 , is now referred to as battery compartment  310 . The battery compartment  310  provides a secure holding compartment for the lithium-ion and/or lithium phosphate batteries that are typically used to power various electrical motors. There may be several batteries that are stored in one of the two battery compartments  310 . There is a battery engagement switch  322 , which allows selection of a single battery or multiple batteries to be engaged. The power from the battery compartments  310  is fed through the electrical conduit through-hole  324 . The electrical current is carried via wires that are conveniently stowed in the electrical conduit  328 . The electrical control boxes  314 , formerly known as electrical control boxes  254  in  FIG. 2 , contains the electrical charging circuitry, remote control for power application to the motors, and smart charging chips for properly monitoring battery discharge and charging. This is an essential part of any remote control power application to prevent the batteries from overheating and catching fire if they are charging or discharging too quickly. Various commercial charging circuits and remote control circuits will be housed in electrical control boxes  314 , and their functions are controlled with the electronic function controller switch  320 . There is a connection between the electronic control boxes  314  and the battery compartments  310  via an electrical conduit  312 . This provides an adequate environment for keeping the electronics free of water and dust contamination. Electrical connector  316  is provided for both AC and DC charging. An environmental cover plate  318  also secures the power connection from exposures to the elements. 
         [0206]      FIG. 4A  shows the basic elements that are mechanically attached to the skateboard deck  100  as seen in  FIG. 2 , mainly the attachment of the baseplate  410 , formally known as baseplate  250  in  FIG. 2 . The baseplate  410  is attached to the skateboard deck  100  (not shown, see  FIG. 2 ) with a component fastener  220  that screws into threaded receptacle  240 . This secures the baseplate  410  to the skateboard deck  100  (not shown, see  FIG. 2 ). The transom plate  435  is attached to the fork hanger  425 . In this case, the invention shows that the transom plate  435  is a unique method for attaching motorized and non-motorized skateboard single wheel assemblies  111 . The fork hanger  425  also provides a means of transitioning the electrical wires through the electrical conduit  328  through electrical conduit through-hole  432 . The wheel assembly  111  is attached to the fork hanger  425  via mounting bolts  455 . 
         [0207]    The transom plate  435  is similar to current skateboard assemblies and uses the same components such as the skateboard kingpin  420 , the top bushing  424 , and the pivot pin  422 . The baseplate  410  provides the kingpin through-hole  412  for the kingpin  420  to fit through and to secure the baseplate  410  to the transom plate  435 . The transom fork hanger assembly  109 , for future reference, is going to include the transom plate  435  and the fork hanger  425 . 
         [0208]      FIG. 4B  is a side cross-sectional view of the transom plate  435 , the base plate  410 , the kingpin  420 , the pivot pin  422 , top-busing/s  424 , bottom-bushing  426 , bottom-bushing washer  427 , and the kingpin locking-nut  428 . This view also shows the side view of the fork hanger  425 . 
         [0209]    In this cross-section view the location of the pivot pin  422  and the resilient pivot pin cup  404  are shown. These structures are made of metal or plastic or a combination. A metal injection, casting, and other molding processes typically make common skateboard hangers. Some newer skateboard hangers are made from composite materials. It is assumed that the injection molding process or other metal or plastic forming processes make the skateboard transom fork hanger assembly  109  in one piece. 
         [0210]    This view  FIG. 4B  shows the baseplate  410  with the skateboard kingpin  420  inserted into the kingpin through-hole  412 . The skateboard kingpin  420  is stopped and held in place at the kingpin counter-bore stop  408 . On the underside of the baseplate  410  is the top-bushing interaction surface  406  that holds the top-bushing/s  424  firmly in place. Depending on the length of the pivot pin  422  and turning requirements, more top-bushings  424  are required. The resiliency of top-bushings  424  and bottom-bushing  426 , and with the open flat space provided by the bushing interaction surfaces  415  and  417 , allows the transom fork hanger assembly  109  to freely slide and rotate about the pivot pin axis  431 . The degree of pivoting about the pivot pin axis  431  is determined by how tight the kingpin locking-nut  428  compresses the top-bushings  424  and the bottom-bushings  426 . The bottom-bushing washer  427  is the metal washer that the kingpin locking-nut  428  pushes onto for compression. It produces uniform compression on the top-bushings  424  and bottom-bushing  426  without distorting or tearing during compression. Also, the ease of rotation about the pivot pin axis  431  is determined by how much compression is applied to the kingpin locking-nut  428  and how smooth are the top-bushing interaction surface  406  and the bushing interaction surfaces  415  and  417 . The pivot pin  422  is held firmly to the transom plate  435  by the pivot pin bolt  442 . Also shown, the through-holes  436 , which secure the wheel assembly  111 , shown in  FIG. 4A , to the fork hanger  425 . The electrical conduit through-hole  432  allows the electrical wires to pass through the fork hanger  425  and mates to the motor/s contained within the wheel assembly  111  (not shown). Accessory through-hole  430  is for attaching accessories to monitor motor or wheel performance such as tachometers. 
         [0211]      FIG. 4C  shows an expanded isometric view of the fork hanger  425  attached to the transom plate  435 . Also shown is the method of attachment of the wheel assembly  111 . The wheel assembly  111  is held in place by mounting bolts  455  that pass through through-holes  436 , spacers  438 , and secured to the threaded-holes  460 . The spacers  438  provide proper spacing and alignment of the wheel assembly  111 . 
         [0212]      FIG. 5A  is an expanded isometric view of the wheel assembly  111 . The wheel assembly Ill is made up of the tire skin  501  and two identical wheel hubs  556 , which comprise the wheel hub assembly  599 . All components rotate about the axis of rotation  500 . The wheel hub assembly  599  is held in position to the fork hangers  425  and by mounting bolts  455 , as shown in  FIG. 4C . The mounting bolts  455  fit into the threaded-holes  516 , which were threaded-holes  460  as shown in  FIG. 4C . These threaded-holes  516  are actually on the motor hub face  529 . The conduit through-hole  551  is for the electrical conduit  328  as shown in  FIG. 4A , and is used to pass wires to the enclosed motors within the motor hub  510 . Bolts  514  are used to secure the internal motors. On the periphery of the two wheel hubs  556  are rings of circles, outside bearing through-holes  536 , and inside bearing through-holes  537 , which are through-holes for epoxy or threaded through-holes for setscrews to attach internal components. Also shown in this view is a space  543  between the two wheel hubs  556 . 
         [0213]      FIG. 5B  is an isometric cross-sectional view of the wheel hub assembly  599 . It is made up of two identical wheel hubs  556 . These two wheel hubs  556  are bolted together with bolts  540 , spacers  542 , and the locking nuts  544  that are engaged via a through-hole  541 .

         [0215]    In this view there are two rings of through-holes, outside bearing through-holes  536  and inside bearing through-holes  537 . The outside bearing through-holes  536  and inside bearing through-holes  537  can be threaded to accept setscrews  531  for securing outside bearings  527  and inside bearings  530 . The outside bearing through-holes  536  and inside bearing through-holes  537 , if not threaded, are used as through-holes to apply epoxy or other materials to secure the bearings in their respective positions. Outside bearing through-holes  536  are used to secure the outside bearing  527 ; whereas, inside bearing through-holes  537  are used to secure inside bearings  530 .

These three components, outside bearing  527 , bearing spacer  528 , and inside bearing  530  slides onto the motor hub  510  until seated against the bearing reference stop  520 . The bearing reference stop  520  is a ring that is welded, machined, or formed onto the motor hub  510  outside surface as part of the motor hub  510 . The motor drive gear  523  has been secured to the motor shaft  525  with setscrew  524 . 
         [0218]    The motor hub assembly  590  slides into the wheel hub  556  until the motor drive gear  523  engages the gear seat  546 . At this point the bearing receiving-holes  532  can be aligned with inside bearing through-holes  537  and outside bearing through-holes  536 . These surfaces are then locked together with setscrews  531 . 
         [0219]      FIG. 5E  is an expanded front-end cross-sectional view of the wheel hub assembly  599  and motor hub assembly  590 .

         [0221]      FIG. 5F  shows the front-end cross-sectional view of the wheel hubs  556  attached to one another forming the wheel hub assembly  599 . The motor hub assemblies  590  are shown inserted into their respective positions within the wheel hub assembly  599 . The motor hub assemblies  590  are shown attached to the wheel hubs  556  with setscrews  531  that engage the inside bearings  530  and outside bearings  527 . The motor drive gear  523  is shown properly seated into the gear seat  546 . 
         [0222]      FIG. 5G  shows the wheel hub assembly  599  attached to the transom fork hanger assembly  109 , which is comprised of the fork hanger  425  and the transom  435 . The attachment of the wheel hub assembly  599  is accomplished with mounting bolts  455  passing through the through-holes  436  and through the spacer  438  that engages the threaded-holes  516  on the motor hub face  529 . 
         [0223]      FIG. 5H  shows a front cross-section orientation of the motor hub assembly  590  within the wheel hub assembly  599 . It also shows the tire skin  501  attached to the wheel hub assembly  599  outer surface with an adhesive  504 . Internal tire material  502  can consist of gases, foam, liquid material or gels. The motor hub  510  is attached to the hanger fork  425  with the motor hub bolt  455  passing through the through-hole  436  and through the spacer  438 , and into the threaded-hole of the motor hub  517 . This secures the motor hub assembly  590  to the fork. 
         [0224]      FIG. 5I  shows a different method of attaching a solid tire to the wheel hub assembly  556 . The tire skin  501  is attached to the wheel hub  556  with tire fasteners  506  that pass through a tire fastener recess  508 . The tire fastener  506  is fastened to a threaded-hole  509  that is machined or formed into the wheel hub  556 . Locking glue or epoxy is used to assure that the tire fastener  506  remains fastened to the wheel hub  556 . 
         [0225]      FIG. 6  shows a side view, as a dimension perspective, of a skateboard with a range of new wheel style assemblies  630 . The average size of the skateboard deck  600  is roughly from 24 inches to, but not limited to, approximately 36 inches in length, and with the present invention the height ranges from generally 3 inches to 5 inches. The side view shows a typical skateboard deck  600 , formerly known as skateboard deck  100  in  FIG. 1  and  FIG. 2 . This drawing and subsequent figures will evolve from the simple non-motorized skateboards to the more complex motorized skateboards and different skateboard wheels with novel features which is referred to as new wheel style assemblies  630 . The transom fork hanger assembly  610  will be used to mount the new wheel style assembly  630  as represented by the dotted line. 
         [0226]      FIG. 7A  is an isometric view of the skateboard deck  600  with an expanded view of one of the deck skins  710  that represents reduced size of conventional skateboard deck skins. Deck skin  710 , deck skin  712 , and deck skin  714  protect the components and component fasteners. This view shows the component fasteners  220  that fasten the baseplate  723  to the skateboard deck  600 . The skateboard deck  600 , formally referred to as skateboard deck  100  as seen in  FIG. 1 , has the same component through-holes as skateboard deck  100 . 
         [0227]    The main purpose of deck skins  710 , deck skins  712 , and deck skins  714  is to provide a gritty surface for the skateboard rider. Additionally, any one of the deck skins  710 , deck skins  712 , and deck skins  714  can be replaced quickly and inexpensively. 
         [0228]    The fork hanger  725  and the transom plate  735  make up the transom fork hanger assembly  780 , formerly referred to as transom fork hanger assembly  610  in  FIG. 6 . In this configuration, oval wheel  740 , formerly referred to as new wheel style assembly  630  in  FIG. 6 , is mounted to the fork hanger  725  via threaded section  707  of axle rod  702  (not shown) and locking nut  718 . The axis of rotation is  705 . 
         [0229]      FIG. 7B  shows the isometric view of a non-motorized skateboard assembly with the respective deck skins  710 ,  712 , and  714 , which shows that the majority of the surface on the skateboard deck  600  is adequately covered.  FIG. 7B  also shows a common left foot placement pattern  759  and right foot placement pattern  758  to maintain normal control and stability when riding. 
         [0230]      FIG. 7C  shows the underside view of two skateboard shoe types: shoe bottoms  760  (L) and  760  (R) and shoe bottoms  761  (L) and  761 (R). Shoe bottoms  760  (L) and  760  (R) and shoe bottoms  761  (L) and  761 (R), are representations of skateboard shoe soles that have unique features dependent on the complementary material used for the deck skin material as seen in  FIG. 7B . 
         [0231]    Shoe bottoms  760  (L) and  760  (R) consist of a retaining matrix material  762 , the heel  763 , and the sole  764 . The retaining matrix material  762  can be molded with magnetic material in the heel  763  and with magnetic material in the sole  764  to form a thick shoe bottom  760  (L) and  760  (R). There are many combinations of materials to form shoes bottoms  760  (L) and  760  (R). 
         [0232]    Shoe bottoms  761  (L) and  761 (R) shows magnets  768  as small permanent magnet plugs that are incorporated into the wells of the retaining matrix material that is typical of shoe sole material. The magnets  768  can be embedded or molded into the entire retaining matrix material  766 . Shoe bottoms  761  (L) and  761 (R) configurations can also be made up of different combinations of materials such as composite sole skins that are taped, glued or fastened to the bottom soles of regular skateboard shoe. 
         [0233]      FIG. 7D  shows the former right foot placement pattern  758  and left foot placement pattern  759  from  FIG. 7B  are now shoe bottoms  760  (L) and  760  (R). The shoe bottoms  760  (L) and  760  (R) are drawn transparent to show the interaction with materials beneath the shoe bottoms of the designated deck skin,  710 ,  712 , and  714  shown in  FIG. 7B . 
         [0234]    The deck skins  710 ,  712 , and  714  have an underlayment of magnetic material  750 ,  752 , and  754 , respectively, that interacts with the sole of the shoe bottoms  760  (L) and  760  (R) or shoe bottoms  761  (L) and  761 (R). When the rider is performing airborne tricks the magnetic coupling generated between the shoe bottoms  760  (L) and  760  (R) or shoe bottoms  761  (L) and  761 (R) and the magnetic material  750 ,  752 , and  754 , used as an underlayment, will create greater control for the skateboard rider. When the skateboard rider completes the airborne trick and lands on the terrain, the gritty deck skins  710 ,  712 , and  714  provide positive control during the “touchdown” phase of the airborne trick and the subsequent ground ride. The interaction with the gritty material of the deck skins  710 ,  712 , and  714  will allow positive control when momentum changes during skateboard maneuvers preventing the rider from sliding off. While performing aerial tricks positive contact and control of the skateboard will be maintained by the skateboard rider due to the magnetic interaction of the shoe bottoms  760  (L) and  760  (R) or shoe bottoms  761  (L) and  761 (R) and the underlayment of magnetic material  750 ,  752 , and  754 . Such aerial tricks may include stands, spins, twirls or other skateboard motions. Typically airborne tricks require the skateboard rider to bend the knees to a high degree and physically grab the skateboard to avoid separation and loss of control. Maneuverability of the skateboard rider is not compromised by this invention but enhanced. 
         [0235]    To separate from the magnetic surface the rider rotates a heel or toe edge out of the plane of the magnetic coupling surfaces. The simple action of pulling or flexing the heel up and applying downward pressure on the toes allows for controlled separation from the magnetic surface and alters the degree of coupling. It is easy to rotate the feet on the surface by minimizing the amount of weight on the shoe sole. This release is accomplished in the same skateboard maneuvers currently performed. The only difference is more positive control of the interaction between the sole of the skateboard shoe and the skateboard itself. A higher degree of precision in performing skateboard tricks can be accomplished because of this optimized control. 
         [0236]      FIG. 7E  deals with the isometric view visualization of the shoe bottoms  761  (L) and  761 (R) and the deck skins  710 ,  712 , and  714  as shown with magnetic material  750 ,  752 , and  754  used as an underlayment. The deck skins  710 ,  712 , and  714  are overlaid onto the magnetic material  750 ,  752 , and  754 , respectively. The magnetic interaction occurs between the shoe bottoms  761  (L) and  761 (R) and the magnetic material  750 ,  752 , and  754  used as an underlayment to the deck skins  710 ,  712 , and  714  as shown in  FIG. 7D  with the shoe bottoms  760  (L) and  760  (R). There are no materials that can be magnetized and no magnets embedded in the matrix material heels  767 . 
         [0237]      FIG. 7F  is an isometric view of hybridized composite deck skins  770 ,  772 , and  774 , shoe bottoms  761  (L) and  761 (R) and shoe bottoms  760  (L) and  760  (R) (transparent for clarity). The hybridized deck skins  770 ,  772 , and  774  refers to: alternating strips of abrasive deck skin  710  and magnetic material  750  forming hybridized composite deck skin  770 ; alternating strips of abrasive deck skin  712  and magnetic material  752  forming hybridized composite deck skin  772 ; and alternating strips of abrasive deck skin  714  and magnetic material  754  forming hybridized composite deck skin  774 . The hybridization formed on the same plane provides a single deck skin cover. This makes it easier for the rider to reconfigure or perform maintenance operations. This new configuration will provide the same interaction between the shoe bottoms  761  (L) and  761 (R) and shoe bottoms  760  (L) and  760  (R) as shown in  FIG. 7D  and  FIG. 7E . This hybridized composite deck skins  770 ,  772 , and  774  will allow the rider to perform tricks or simple maneuvers in regular skateboarding activities or when using the novel shoe soles to perform enhanced tricks and maneuvers. 
         [0238]      FIG. 7G  shows an upper isometric view of a skateboard deck  790  that has incorporated into the top surface an array of magnets  794 , see inset  796 . These magnets  794  are epoxied into the receptacles  792 , also see inset  796 . The magnets  794  are epoxied in place slightly below or flush with the surface of the skateboard deck  790 . The surface of the skateboard deck  790  is covered with the abrasive deck skins  710 ,  712 , and  714  that are represented as dashed line areas. The component mounting fasteners  220  are used to secure the skateboard deck  790  to the base plate  723  that pass through the through-holes  230 . The magnets  794  will provide maximum coupling of the skateboard deck  790  to the shoe bottoms  761  (L) and  761  (R) with and shoe bottoms  760  (L) and  760  (R) (not shown). 
         [0239]      FIG. 7H  is an isometric view of the transom fork hanger assembly  780  and the expanded view of the new wheel style assembly  630 . Together, the transom plate  735  and the fork hanger  725 , make up the transom fork hanger assembly  780 . The transom fork hanger assembly  780  connects to the base plate  723 , similarly as the kingpin &amp; pivot-pin assembly  480 , as shown in  FIG. 4B . The transom plate  735  has the kingpin through-hole  732  as well as the pivot pin seat  737  shown for general reference. The new wheel style assembly  630  has an oval wheel  740  with an axel-rod through-hole  733 , a bearing recess  745 , a wheel to bearing spacer  738 , and a bearing  730 . For convenience the new wheel style assembly  630  will be called the wheel assembly  630  from this point on. The wheel assembly  630  is connected to the transom fork hanger assembly  780  by aligning the respective axis of rotation  705  to be collinear with axel-rod  702 . The threaded end  707  of the axel-rod  702  passes through the through-hole  720  and through one of the spacers  716 . The threaded end  707  of the axel-rod  702  is passed through the bearing  730 , the bearing spacer  716 , through the wheel axel-rod through-hole  733 , the spacer  716 , through the bearing  730 , the spacer  716 , and the second through-hole  720 . The installed wheel assembly  630  is then secured in place with the washer  715  and the locking nut  718  tightened on both ends of the threaded ends  707  of the axel-rod  702 . The spacers  716  are used to keep proper spacing of the sides of the oval wheel  740  from rubbing on the inside of the fork arm  725 . 
         [0240]      FIG. 7I  is an end-on view of the non-motorized skateboard configuration. This end-on view shows the skateboard deck  600  or skateboard deck  790 , base plate  723 , and kingpin &amp; pivot pin assembly  480  (see  FIG. 4B ) connecting to the transom fork hanger assembly  780 , and a perspective front-end view of the various wheel assemblies  630 . The kingpin &amp; pivot pin assembly  480  joins the skateboard transom fork hanger assembly  780  to the base plate  723 . To be described below are the geometry, size, and relative perspective end-on view showing multiple wheel profiles  740 ,  744 ,  747 , and  748  that will provide efficient reconfigurable choices for performing tricks on skateboard-park surfaces and objects. The common element is the oval shape for deriving skateboard wheel geometries. The basic wheel is the oval wheel  740 . The deep V-groove wheel  748  can be used for curbs and planters, while a U-groove wheel  744  can be used for riding the rails. For more aggressive turning on curves, a double-sphere wheel  747  is preferred. A full single sphere wheel  746  (not shown) can be used for high-speed downhill racing and better agility on curves. Longer spacers  716  may be required for centering of some wheel geometries. 
         [0241]      FIG. 7J  is an isometric and a front view of the oval wheel  740 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The axel-rod through-hole  733  is for the axle rod  702  (see  FIG. 7H ). The oval wheel  740  will be the root geometry from which other shape profiles will be designed. The oval, circular, and rounded shapes are important. If flat cylindrical geometries were used, rotation about the pivot-pin  720  (not shown) would require significantly more torque or be impossible to turn. 
         [0242]      FIG. 7K  is an isometric and a front view of the U-groove wheel  744 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The through-hole  733  is for the axle rod  702  (see  FIG. 7H ). The front view shows the U-groove wheel  744  that will give the rider the capability of riding handrails and other curvilinear surfaces. The U-groove wheel  744  is machined, molded, or formed into the oval wheel  740 . 
         [0243]      FIG. 7L  is an isometric and front view of the double-sphere wheel  747 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The through-hole  733  is for the axle rod  702  (see  FIG. 7H ). The front and isometric views show the profiles of the two spheres that will allow for riding on linear geometrical surfaces. The front view of  FIG. 7L  depicts the double-sphere wheel  747  expanding into a single sphere or full-sphere wheel  746  as illustrated by the dashed circle. 
         [0244]      FIG. 7M  is an isometric and front-end view of the deep V-grooved wheel  748 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The through-hole  733  is for the axle rod  702  (see  FIG. 7H ). The front view shows the deep V-groove wheel  748  that will give the rider the capability to negotiate curbs, handrails and other grinding surfaces without damaging the skateboard or the riding surfaces. The deep V-groove wheel  748  is machined or molded into the oval wheel  740 . 
         [0245]      FIG. 7N  is an isometric and front-end view of the stud wheel  749 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The through-hole  733  is for the axle rod  702  (see  FIG. 7H ). The oval wheel  740  is the starting form for stud wheel  749 , and designed for ice racing or traversing icy terrains. A stud  742  is inserted into the skateboard wheel material, which is typically polyurethane. Machining, casting or forming these wheels with different compounds, such as polyurethane and the insertion or encapsulation of the studs  742  or cone structure, will create an adequate gripping surface on the ice or slippery surfaces. The diamond features represented by stud  742  in the stud wheel  749  need not be metal inserts. 
         [0246]      FIG. 8A  is an angled side view of a motorized skateboard. This figures shows two motor assemblies  820  that mount on the underside of the transom plate  735 . The transom fork hanger assembly  780  is comprised of the transom plate  735  and the fork hanger  725 . The skateboard deck  600 , formerly skateboard deck  100  in  FIG. 1 , is fastened to the base plate  723  in the same manner as described in  FIG. 4B . The kingpin &amp; pivot pin assembly  480  attaches the base plate  723  and to the transom plate  735  as described in  FIG. 4B . Attached to the fork hanger  725  is the drive wheel assembly  810 . The drive wheel assembly  810  is mounted to the transom fork hanger assembly  780  as described in  FIG. 7H . The mounting of the drive wheel assembly  810  is identical to the drive wheel assembly  630  with the exception that the drive belt  880  is added to the wheel drive gear  885  before assembly. The oval drive wheel  850 , used in the drive wheel assembly  810 , is a specialized wheel and has a wheel drive gear  885  mounted between two identical oval wheel hubs  842 . The drive belt  880  drives the drive gear  885 . The motor  882  is mounted to the underside of the transom plate  735  with the motor mounting clamps  865  and secured with bolts  867 . 
         [0247]      FIG. 8B  is a lower side view of the underside of the transom fork hanger  780 . This view better illustrates the relationship of the motor assembly  820  and the oval drive wheel  850 . The motor assembly  820  includes the motor mounting bolts  867 , motor mounting clamps  865 , motor  882 , the drive gear  890 , motor spindle  892  and not shown, the drive gear setscrew  881 . The transom plate  735  has mounted to its underside a motor  882 , which is held in place by two motor mounting clamps  865 . The motor mounting clamps  865  are affixed to the underside of the transom plate  735  by four bolts  867 . The underside-mounted motor  882  has attached to its motor spindle  892  a drive gear  890 . The drive gear  890  turns the drive belt  880 , which drives the wheel drive gear  885 . The wheel drive gear  885  rotates the two oval wheel hubs  842  about the axis of rotation  705 . 
         [0248]      FIG. 8C  is an isometric view of the oval drive wheel  850 . The oval drive wheel  850  can be a monolithic piece manufactured by molding, casting or other forming methods. The oval drive wheel  850  has two oval wheel hubs  842  with an interposing wheel drive gear  885 . The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The through-hole  733  is for the axle rod  702  (see  FIG. 7H ). There is a chamfer  894  on the inside of the oval wheel hubs  842 . The chamfer  894  maintains alignment of the drive belt  880  (see  FIG. 8B ) and prevents unnecessary wear by keeping it centered. 
         [0249]      FIG. 8D  is an expanded elevated off-axis view of the oval drive wheel  850  and illustrates the relationship of the drive gear  885  to the wheel halves  842 . In contrast to the monolithic body in  FIG. 8C , this design shows a reconfigurable oval drive wheel  850 . The two wheel halves  842  are joined together with wheel drive gear  885 , which can be large or small. The size of the wheel drive gear  885 , in conjunction with the drive gear  890  (not shown), dictates speed. The alignment rods  891  pass through the wheel drive gear  885  through through-holes  887  and are press-fit into the receiving holes  893  of the wheel hubs  842 . The invention also incorporates a bearing recess  889  within the wheel drive gear  885 . This bearing recess  889  is located on both sides of the wheel drive gear  885  and is on the axis of rotation  705 . A bearing recess  837  is located on the inside of the wheel hubs  842 . This bearing recess  837  is a load sharing option. This optional bearing recess  837  is for heavy loads or large skateboards to distribute the weight more uniformly. A bearing recess  745  is located on the outside of the wheel hub  842 . Axel-rod through-hole  733  provides a pass through for the axel-rod  702  (see  FIG. 7H ). Axel-rod through-holes  833  are used for wheel drive gear  885  assembly. 
         [0250]      FIG. 8E  is an isometric view of a partially assembled drive wheel  850 . The wheel axis of rotation is  705 . The bearing recess is located at  745 . Inserting the alignment rods  891  into the receiving holes shown in  FIG. 8D  completes the assembly of the wheel drive gear  885 . The gear bearing recess  889  is also part of the access hole  733  for the axel-rod  702  (not shown). Pushing these two wheel hubs  842  together for a completed drive gear wheel  850  completes the oval drive wheel assembly  850 . Just visible is the axel-rod through-hole  733  for the axel  702 , which passes through all of the components of the drive wheel  850 . 
         [0251]      FIG. 8F  shows an expanded isometric view of the undercarriage of the transom plate  735  and the staging of attaching the components. The transom plate  735  is attached to the base plate  723  through the kingpin &amp; pivot pin assembly  480  (see  FIG. 8A ). 
         [0252]    There are two axis of rotation in  FIG. 8F  that involve drive belt  880 . The first axis of rotation is  883  of the motor spindle  892  and the second axis of rotation is  705  of the drive wheel assembly  850  as shown in  FIG. 8D . Although one drive belt  880  is used in the assembly, it is represented twice to illustrate its function with regard to the two axis of rotation  883  and  705 . 
         [0253]    The motor  882  is attached to the bottom of the transom plate  735  by using two motor mounting clamps  865  along with four attachment bolts  867 . These attachment bolts  867  follow the alignment markings  863  ( a, b, c, d ) through the through-holes  868  of the motor mounting clamps  865  to the threaded-holes  869  in the bottom of the transom plate  735 . The drive gear  890  is mounted on the motor spindle  892  and held in place with setscrew  881 . 
         [0254]    The oval drive wheel assembly  850  is assembled as indicated in  FIG. 8D . The drive belt  880  is placed into position around the wheel drive gear  885 . The oval drive wheel assembly  850  (see  FIG. 8C ) is placed between the hanger forks  725 . The axel-rod  702  is introduced through the hanger forks  725  through the through-hole  720 , which also defines the axis of rotation  705 . The bearing to wheel spacer  738  is placed on the axel-rod  702  along with the bearing  730 . The bearing  730  is seated in the bearing recess  745 . Next, the appropriate bearing to fork spacer  716  is added, if needed, as shown in  FIG. 7H . The axel-rod  702  spans both hanger forks  725  through the respective through-holes  720 . On both sides of the hanger forks  725  are spacers  715  placed onto the threaded section  707  of the axel-rod  702 . The locking nuts  718  are added and tighten on the threaded section  707 . The drive belt  880  is coupled to the drive gear  890 , which is aligned to the axis of rotation  883  of the motor spindle  892 . 
         [0255]      FIG. 8G  is the off-axis underside view of the skateboard deck  600  showing a dual motor transom fork hanger truck assembly  825 . The dual motor transom fork hanger truck assembly  825  is made from assemblies: drive wheel assembly  810 , two motor assemblies  820 , and transom fork hanger assembly  780  (see  FIG. 8B ). This underside view shows there is room to incorporate another motor onto the same transom plate  723 . Multiple motors will enhance the uphill capabilities speed or torque to distribute power. Also shown is a single motor transom hanger fork truck assembly  828 . 
         [0256]      FIG. 8H  is an isometric view of the studded drive wheel  849 . The studded drive wheel  849  can be a monolithic piece manufactured by molding, casting or other forming methods. The studded drive wheel  849  has two oval wheel hubs  842  with an interposing wheel drive gear  885 . The two oval wheel hubs  842  have studs  742  incorporated into or onto the surfaces. The isometric view shows the common elements for the insertion of the bearing spacer  738  (not shown) and bearing recess  745 . The axel-rod through-hole  733  is for the axle-rod  702  (see  FIG. 7H ). There is a chamfer  894  on the inside of the oval wheel hubs  842 . The chamfer  894  maintains alignment of the drive belt  880  (see  FIG. 8B ) and prevents wear by keeping it centered. 
         [0257]      FIG. 8I  is a front-end view of the studded drive wheel  849 . The important elements of this studded drive wheel  849  include the tapering curve  845  of the oval wheel hubs  842  indicated by the tapering curve  845  and the high degree of traction provided by the studs  742 . This studded drive wheel  849  can be manufactured by a molding, casting or forming process or assembled from parts similar to the method outlined in  FIG. 8D . 
         [0258]      FIG. 8J  is an underside isometric view of a dual motor transom fork hanger truck assembly  825  (see  FIG. 8G ) and the non-motorized front-end transom fork hanger assembly  780  with studded oval wheel  749 . Skateboard deck  600  is ready for the attachment of the electronic assembly  107  via the through-holes  232 ,  234 , and  232 . 
         [0259]      FIG. 9A  is an isometric view of a two-bearing transom fork hanger truck assembly  999 . Also shown is the dashed line cross-section plane  910  that will be referenced in  FIG. 9G . In this figure, the base plate  923  has threaded-holes  240 . These threaded-holes  240  are used to fasten the skateboard deck  100  to the base plate  923  with component fasteners  220 . The base plate  923  is similar to baseplate  250  in  FIG. 2  and to base plate  410  in  FIG. 4 . However, the base plate  923  is slightly wider to accommodate springs  912 . The base plate  923  is connected to the transom plate  935  in the same manner as shown in  FIG. 4B  with the kingpin &amp; pivot pin assembly  480 . The fork hanger  925  is attached to the transom plate  935  with bolts  902 , which are inserted into through-holes  904 . Also shown in this drawing is the motor axle flange-locking nut  920 . This motor axle flange-locking nut  920  is fastened to the fork hanger  925  with bolts  926 . These bolts  926  pass through slotted through-holes  921  and engage threaded-holes  928  (not shown) in the fork hanger  925 . Also shown in  FIG. 9A  is the tire tread  901  with weep-holes  908  to allow excess adhesives to weep out from under the tire to minimize bubbling which would cause a bumpy ride. 
         [0260]      FIG. 9B  is a compound expanded isometric view of the two-bearing transom fork hanger truck assembly  999 . Base plate  923  has been rotated  900  out of its normal orientation to expose details that have been added. The base plate  923  has incorporated spring retaining-holes  915  into the bottom. The spring retaining-holes  915  will secure the top part of the spring  912  when the base plate  923  is in its normal horizontal position. The spring retaining-holes  914  located in the top surface of the transom plate  935  are required to contain springs  912 . The pivot pin retaining-hole  916  is identical to pivot pin retaining-hole  402 , see  FIG. 4B . Kingpin through-holes  919  and  918  are in the base plate  923  and the transom plate  935 , respectively. The transom plate  935  and the fork hanger  925  are bolted together with bolts  902 . The bolts  902  pass through through-holes  904  and are tightened into the threaded-holes  906  in the side of the transom plate  935 . This is symmetric with regard to the opposite fork hanger  925 . 
         [0261]    The fork hanger  925  has a bearing retention hole  938  and a stop wall reference  939 . The large bearing spacer  932  fits into the bearing retention hole  938  and rests against the stop wall reference  939 . Bearing  930  is seated into the bearing-retaining hole  938  flush with the large bearing spacer  932  preventing any binding of the bearing surfaces that would cause friction. The tire skin  901  is shown off of the wheel hub assembly  986 . The tire skin  901 , wheel hub assembly  986 , and inner race of bearing  930  all rotate about the axis of rotation  900 . The small bearing spacer  934  is placed on the wheel hub axel  957 . The small bearing spacer  934  will prevent the outer bearing race of bearing  930  from rubbing the wheel hub flange  955 . With the large bearing spacer  932  and small bearing spacer  934  in place, the wheel hub assembly  986  can slide into the bearing  930 . The inner bearing race of bearing  930  fits snugly over the wheel hub axel  957 . This will allow the external threads  952  of the hollow motor axle union  950  to pass through the fork hanger through-hole  927 . By tightening the motor axle flange-locking nut  920  onto the external threads  952  of the stationary hollow motor axle union  950 , while engaging its internal threads  929  with the external threads  952 , will secure the wheel hub assembly  986 . The tire skin  901  is placed on the wheel hub assembly  986  prior to it being installed within the fork hangers  925 . This will allow the wheel hub assembly  986  to freely rotate with the tire skin  901 . The wheel hub assembly  986  and its contents will be described in  FIG. 9C . 
         [0262]      FIG. 9C  is an isometric cross-sectional view of the wheel hub assembly  986 , an isometric side view of the internal components of the carriage motor assembly  985 , and the simple motor assembly  988 , which will be described in  FIG. 9E  and  FIG. 9F , respectively. The wheel hub assembly  986  is made up of the wheel hub flange  955 , wheel hub axel  957 , the wheel hub drum  940 , and the motor torque transfer wheel  990 . The wheel hub flange  955  and the wheel hub drum  940  are fastened together with fasteners  944 . The fasteners  944  are received by the threaded-holes  949  and passed through the countersunk through-holes  948 . The interior of the wheel hub assembly  986  contains the torque transfer wheel  990 . This motor torque transfer wheel  990  is fastened to the wheel hub drum  940  with fasteners  946 . These fasteners  946  are screwed into threaded-holes  992  on the circumference of the motor torque transfer wheel  990 . This motor torque transfer wheel  990  will be described in detail in  FIG. 9D . 
         [0263]    The wheel hub assembly  986  rotates around the axis of rotation  900 . The through-hole  978  of the stationary hollow motor axle union  950  serves as a passage for the electrical conduit  328  from the batteries  310  (see  FIG. 3 ) to the motors  960 . The non-interference zone  953  is an open space between the inside surface of wheel hub axel  957  and the outside surface of the stationary hollow motor axle union  950 . The external threaded end  977  of the stationary hollow motor axle union  950  engages the motor mount flange  970  of the simple motor assembly  988 , by threading into the internal threads  976 . Similarly, the external threaded end  977  of the stationary hollow motor axle union  950  engages the motor mount flange  970  of the carriage motor assembly  985 , by the threading into the internal threads  976  as shown in  FIG. 9E . 
         [0264]      FIG. 9D  shows isometric views of the wheel hub assembly  986  (inset) and the internal contents of the expanded wheel hub assembly  987 . The expanded wheel hub assembly  987  is made up of the wheel hub flange  955 , wheel hub axel  957 , the wheel hub drum  940 , the motor torque transfer wheel  990 , the simple motor assembly  988 , and the carriage motor assembly  985 . The wheel hub drum  940  has counter sunk through-holes  948  for the fasteners  946  that thread into the threaded-holes  992  of the motor torque transfer wheel  990 . The motors  960  are connected to the motor torque transfer wheel  990  by locking the motor spindle  967  into the motor spindle locking hub through-hole  994 . The motor spindle  967  is locked into the motor spindle locking hub through-hole  994  by setscrews  995 . The setscrews  995  are loaded into threaded-holes  996  around the motor spindle-locking hub  997  of motor torque transfer wheel  990 . There are six threaded-holes  996  on the motor spindle locking hub  997  that lock in place the motor spindles  967  for redundancy. There are two kinds of motor hub assemblies. One is a simple motor assembly  988 , which has mounting screws in the back of the motor that allows for easy motor mounting. A more complex mounting scheme is needed for motors that only have mounting holes on the same side that the active motor spindle is located. This mounting configuration is referred to as the carriage motor mount assembly  985 . 
         [0265]      FIG. 9E  is an isometric view of the expanded simple motor assembly  991  and an isometric view of the assembled simple motor assembly  988  shown as an inset. The mounting of the motor  960  to fit on the stationary hollow motor axle union  950  is accomplished by using a simple motor mounting adapter plate  961  which has a motor spindle through-hole  966  and through-holes  962  for attaching the motor mounting bolts  964  to the back of the motor  960  to the rear motor threaded-holes  963  (not shown; identical to front threaded-holes  965 ). The simple motor mounting adapter plate  961  is mounted onto the motor mount flange  970 . The simple motor mounting adapter plate  961  is secured to the motor mount flange  970  by bolts  974  that pass into through-holes  972  and into the threaded-holes  968  of the simple motor mounting adapter plate  961 . The stationary hollow motor axle union  950  is threaded into the motor mount flange  970  by threading the external threads  977  into the internal threads  976 , which are contained in the large threaded through-hole  975 . This completes the formation of the simple motor mount assembly  988 . 
         [0266]      FIG. 9F  is an expanded isometric view of the expanded carriage motor assembly  993  and an inset of a completed carriage motor assembly  985 . Carriage motor assembly  985  is used to accommodate motors that do not have threaded mounting holes on the back of the motor. To form the carriage motor assembly  985 , the motor  960  with threaded-holes  965  on the side of the motor spindle  967 , is fastened to the carriage motor mounting adapter plate  969  by using motor mounting bolts  964 , which pass through through-holes  971 , and into the threaded-holes  965  of the motor  960 . The carriage motor mounting adapter plate  969  is mounted to the motor mount flange  970  by using carriage support rods  980  that have threaded ends  982 . The motor mount flange  970  and carriage motor mounting adapter plate  969  are joined together by using carriage support rods  980 . Bolts  974  are passed through the through-holes  973  of the carriage motor mounting adapter plate  969  and screw into the threaded-holes  982  of the carriage support rods  980 . Bolts  974  are passed through the through-holes  972  of the motor mount flange  970  and screw into the threaded-holes  982  of the carriage support rods  980 . The stationary hollow motor axle union  950  is threaded into the motor mount flange  970  by threading the external threads  977  into the internal threads  976 , which are contained in the large threaded through-hole  975 . This forms the carriage motor assembly  985 . 
         [0267]      FIG. 9G  is a front-end cross-sectional view defined by the cross-section plane  910  in  FIG. 9A . The cross-section plane  910  cuts the fork hanger  925  through the plane that shows a cross-section of components that rotate about the axis of rotation  900  or seated on the axis of rotation  900 , such as the bearing-retaining hole  938  and the fork hanger through-hole  927 . Within the bearing-retaining hole  938  is seated the large bearing spacer  932  that keeps the bearing  930  properly positioned when both are inserted into the bearing-retaining hole  938 . Small bearing spacer  934  provides the proper separation of the bearing  930  from the wheel hub flange  955 . The bearing  930  and the small bearing spacer  934  slide onto the stationary hollow motor axle union  950 . Wheel hub flange  955  connects to the wheel hub drum  940  using fasteners  944  that pass through the counter-sunk through-holes  948 , and thread into the threaded-holes  949 . The cross-section plane  910  shows the motor  960  mounted to the carriage motor mounting adapter plate  969  with motor mounting bolts  964  that pass through the through-holes  971  of the carriage motor mounting adapter plate  969 , and are thread into the threaded-holes  965  of the motor  960 . The motor torque transfer wheel  990  is secured to the wheel hub drum  940  using fasteners  946  that pass through the countersunk through-holes  948 , and screw into the threaded-hole  992 . This is done in multiple places to secure the motor torque transfer wheel  990  to the motor hub drum  940 . The motor spindle  967  is secured to the motor torque transfer wheel  990  by inserting the motor spindle  967  into the motor spindle locking hub through-hole  994  of the motor spindle locking hub  997 , and tightening the multiple setscrews  995  that are inserted into the threaded-holes  996  of the motor spindle locking hub  997 . The tightening of the setscrews  995  is accomplished by inserting a setscrew wrench through an access hole  942 . 
         [0268]    The carriage motor mounting adapter plate  969  is fastened to the motor mount flange  970  with multiple carriage support rods  980 . Bolts  974  pass through the through-holes  973  of the motor mount flange  970  and into the threaded-holes  982  of the carriage support rods  980 . The carriage motor mounting adapter plate  969  is fastened to the other end of the carriage support rod  980  with bolts  974  that pass through the through-holes  972 , and thread into the threaded-holes  982  in the carriage support rods  980 . The external threaded end  977  of stationary hollow motor mount axel union  950  is threaded into the internal threads  976  of the motor mount flange  970 . This forms the complete carriage motor mount assembly  985  (see inset  986  in  FIG. 9D ). 
         [0269]    The opposite external threaded end  952  of the stationary hollow motor mount axel union  950  is passed through the inside of the wheel hub axel  957  and through the fork hanger through-hole  927  of the fork hanger  925 , and threaded onto the motor axle flange-locking nut  920  by engaging the internal threads  929  of the motor axle flange-locking nut  920 , and the external threads  952  of the stationary hollow motor mount axel union  950 . Once the motor axle flange-locking nut  920  is tightly threaded onto the stationary hollow motor mount axel union  950 , the motor axle flange-locking nut  920  is tightened to the fork hanger  925  with bolts  926  that pass through slotted through-holes  921  of the motor axle flange-locking nut  920 , and thread into the threaded-holes  928  of the fork hanger  925 . The electrical conduit  959  provides a path for power to the motors  960 . The electrical conduit  959  passes through the inside of the stationary hollow motor mount axel union  950 , motor mount flange  970 , and to the motor  960 . This completes the two-bearing transom fork hanger truck assembly  999 . 
         [0270]      FIG. 10A  is a side view of the treaded skateboard assembly  1012 . This view shows the entire configuration of the treaded skateboard assembly  1012  from the skateboard deck  100 , the electronic assembly  107 , the transom fork hanger assembly  109 , the wheel assembly  11 , a tread  1000  instead of the tire skin  501 , and the kingpin &amp; pivot pin assembly  480  that are identical to  FIG. 1  through  FIG. 5 . 
         [0271]    Motorized and non-motorized versions of the wheel-based skateboard see in  FIG. 1 , are transformed into a treaded skateboard assembly  1012  by adding a tread  1000  to the front and rear wheel hub assemblies  599  (see  FIG. 5A ). Sizes and proportions are related to the size of treads to be used and whether or not the skateboards are motorized or non-motorized. The side view in  FIG. 10A  illustrates the tread  1000  and the parts that make it unique. The tread riser  1010  is a vertical part of the tread  1000 . The tread riser  1010  and the V-notches  1015  are incorporated into the body of the tread  1000  during the molding or forming process. The tread  1000 , the tread riser  1010 , the V-notches  1015 , and the tread depressions  1005  are molded or formed as one solid piece. In order to provide traction on different surfaces the tread  1000  has tread depressions  1005 . 
         [0272]      FIG. 10B  is an isometric side view of the treaded skateboard assembly  1012  showing the mechanical fasteners system implemented on the motorized skateboard as shown in  FIG. 2 . 
         [0273]      FIG. 10C  is an expanded isometric view of the treaded skateboard  1012  and its components. Shown in this view are two-wheel hubs  556  that engage the inside surface  1002  of the tread  1000 . There is a tread riser guide channel  1020 , formerly space  543 , between the two wheel hubs  556  as seen in  FIG. 5A  that forms by the thickness of the spacer  542 , which separates the two hubs  556  of the wheel hub assembly  599 . This space  1020  is now called the tread riser guide channel  1020 . The tread riser guide channel  1020  is constraining the tread riser  1010  by preventing the tread  1000  from walking off the surface of the hub assemblies  556 , and keeps the tread  1000  aligned in the direction the skateboard is traveling. Also shown in  FIG. 10B  is a sealing band  1030  that seals the outside bearing through-holes  536  and the inside bearing through-holes  537 . This prevents moisture and debris from entering the inside of the wheel hub assembly  599  (see  FIG. 5A ). 
         [0274]      FIG. 10D  is an isometric view of the tread  1000  as shown in its normal constrained shape as it traverses around the wheel hub assemblies  599 . The V-notch  1015  is required to allow the maneuvering of the tread around the wheel hub assembly  599 . Based on the hardness of the tread material, it may compress, bulge or tear if the V-notches  1015  are not incorporated into the tread riser  1010 . A compressed V-notch  1024  is shown to illustrate how the tread riser  1010  conforms to the wheel hub assembly  599  (see  FIG. 5A ). 
         [0275]      FIG. 10E  shows the front-end view of the treaded skateboard assembly  1012  and a cross-sectional front view of the tread  1000  as it is wrapped around the wheel hubs  556  that forms the wheel hub assembly  599 , and the tread riser guide channel  1020 . The wheel hubs  556  have outside bearing through-holes  536  and the inside bearing through-holes  537 , represented by the dashed circles, that are covered with a sealing band  1030  to prevent contamination such as sand, water, and other debris from compromising the internal components contained within the wheel hub assembly  599 . This view best shows the hub fillet  1025 . The hub fillet  1025  is on both inside edges of the wheel hubs  556 , and smoothens the edges of the tread riser guide channel  1020  for the tread riser  1010 . The tread riser guide channel  1020  retains the tread riser  1010  of the tread  1000  and holds the tread  1000  on the wheel hub assembly  599  by preventing the tread  1000  from walking off of the wheel hub assembly  599 . The motor hub assembly  590  (not shown, see  FIG. 5G ) is installed within the wheel hub assembly  599  and attached to the fork hanger  425 . 
         [0276]      FIG. 10F  is a front view of the fully motorized treaded skateboard assembly  1012 . Tread depressions  1005  are for gripping surfaces and preventing hydroplaning. Another important feature is the curvatures of the treads  1000  that allows steering and turning capabilities. By keeping the tread  1000  oval in shape, or partially rounded, the transom fork hanger assembly  109  rotates about the pivot pin  422  and about the tread oval axis of symmetry  1007  of the tread  1000 . The tread  1000  is normally stretched between the two wheel hub assemblies  599 . When rotation is initiated, the inside portion of the tread  1000  on the inside of the turn, is shortened. The tighter the radius of curvature required for the turn, the inside of the tread  1000  retracts, causing the tread  1000  to tilt and rotate about the tread oval axis of symmetry  1007 . 
         [0277]      FIG. 10G  is an expanded isometric view of the tread drive hub assembly  1006  showing the incorporation of the positive sprocket drive gear  1090 . In previous versions of the wheel hub assembly  599 , the spacers  542  were used to provide the tread riser guide channel  1020  for the tread riser  1010  to stabilize the tread  1000 , and to prevent the tread  1000  from walking off or sliding off of the wheel hubs  556 . The tread drive hub assembly  1006  is redesigned to function in the same manner with regard to the tread riser guide channel  1020  but with an additional improvement of incorporating a positive sprocket drive gear  1090 . This positive sprocket drive gear  1090  replaces the spacers  542 . The thickness of the positive sprocket drive gear  1090  is similar to the thickness of the spacers  542 , which maintained the proper spacing between the wheel hubs  556  so that the tread riser  1010  moves freely between the two wheel hubs  556  and stabilizes the position of the tread  1000 . With the addition of this positive sprocket drive gear  1090 , better traction is delivered to the tread  1000  to prevent slipping in the event sand and other debris is captured between the inside surface  1002  and the surface of the wheel hub  556  (see  FIG. 10B ). 
         [0278]    The tread drive hub assembly  1006  is assembled in the same manner as the wheel hub assembly  599  as shown in  FIG. 5D . The two wheel hubs  556  are bolted together with bolts  1074  which pass through the through-holes  1076 , the appropriate thin washer  1072 , the positive sprocket drive gear  1090 , the thin washer  1072 , on the other side of the positive sprocket drive gear  1090 , the through-holes  1076  on the second hub  556 , and finally tightened in place with locking nuts  1070 . The wheel hubs  556  have outside bearing through-holes  536  and the inside bearing through-holes  537  that are covered with a sealing band  1030  to prevent contamination such as sand, water, and other debris from compromising the internal components contained within the tread drive hub assembly  1006 . 
         [0279]      FIG. 10H  is an isometric cross-sectional view of only the tread riser guide  1096  found within the tread  1000  and the isometric profile of the positive sprocket drive gear  1090 . The receiver sprocket  1098  of the tread riser guide  1096  couples to the positive sprocket drive gear  1090  by engaging the sprocket tooth  1097 . This addition to the tread riser guide  1096  prevents wheel hub  556  slippage between the tread drive hub assemblies  1006  and the inside surface  1002  of the tread  1000 . The receiver sprocket  1098  also functions to prevent the over compression and distortion of the tread riser guide  1096  as the V-notches  1015  did in  FIG. 10B . This maintains a positive driving force on both tread drive hub assemblies  1006  and the inside of tread  1000  to prevent sand, water, snow, ice, and other debris from being lodged between the two surfaces: the inside surface  1002 , refer to  FIG. 10C , and the surface of the tread drive hub assembly  1006 . 
         [0280]      FIG. 10I  is an isometric view of the smooth tread  1080  showing internal structure of the tread riser guide  1096  incorporated into the inside surface  1002  of the smooth skin tread  1080 . The receiver sprocket  1098  couples to the sprocket tooth  1097  of the positive sprocket drive gear  1090  (see  FIG. 10H ). The receiver sprocket  1098  serves the same purpose as the V-notches  1015  as shown on FIG.  10 C. The receiver sprockets  1098  also eliminates over compression of the tread riser guide  1096  when traversing the tread drive hub assembly  1006 . If these geometries, the receiver sprockets  1098  or the V-notches  1015  as shown on  FIG. 10C  are not present, then over compression of the material will eventually fatigue and fail. This would result in the tread riser guide  1096  cracking and splitting away from the main part of the smooth tread  1080 . 
         [0281]      FIG. 10J  is an isometric view of the recessed tread skin  1082 . The recessed tread skin  1082  shows the tread recesses  1081  for traction and evacuating water to prevent hydroplaning. Also shown is the internal construction of the tread riser guide  1096  incorporated into the inside surface  1002 . The receiver sprocket  1098  couples to the sprocket tooth  1097  of the positive sprocket drive gear  1090  as shown in  FIG. 10H . The receiver sprocket  1098  serves the same purpose as the V-notches  1015  as shown on  FIG. 10C . 
         [0282]      FIG. 10K  is an isometric view of the riser tread skin  1084  with riser treads  1085  and showing internal structure of the tread riser guide  1096  incorporated into the inside surface  1002  of the riser tread skin  1084 . The receiver sprocket  1098  couples to the sprocket tooth  1097  of the positive sprocket drive gear  1090  (see  FIG. 10H ). The receiver sprocket  1098  serves the same purpose as the V-notches  1015  as shown on  FIG. 10C . The riser treads  1085  are outward projections of the former geometry of the tread depressions  1005 . These riser treads  1085  projecting out of the plane of the riser tread skin  1084  offer superior gripping and digging characteristics when confronted with sand, snow, ice, and mud. 
         [0283]      FIG. 10L  is an isometric view of the studded tread skin  1086  with the main characteristic of this tread being the studs  1083 . The inset area  1008  shown in this figure will be enlarged in  FIG. 10M  to show greater detail of the studs  1083 .  FIG. 10L  shows internal structure of the tread riser guide  1096  incorporated into the inside surface  1002  of studded tread skin  1086 . The receiver sprocket  1098  couples to the sprocket tooth  1097  of the positive sprocket drive gear  1090  (see  FIG. 10H ). The receiver sprocket  1098  serves the same purpose as the V-notches  1015  as shown in  FIG. 10C . These studs  1083  projecting out of the plane of the tread  1086  offer superior gripping and digging characteristics when confronted with sand, snow, ice, and mud. 
         [0284]      FIG. 10M  is an enlarged isometric view of the inset  1008  of the forward section of the studded tread skin  1086  shown in  FIG. 10L . The studs  1083  can be metal or hard plastic and the geometries can be simple round posts or diamond shape. Metal studs would be preferred for riding on ice and compacted snow. Other composite materials may be used for mud, snow, or sandy terrain. 
         [0285]      FIG. 10N  is an isometric view showing the vertical cog-tooth tread-drive hub assembly  1093 . It is comprised of the outside cog-teeth  1031  and the inside cog-teeth  1032  that are attached to the circumference of the two wheel hubs  556  as shown in  FIG. 10G . The circumferential outside cog-teeth  1031  and the circumferential inside cog-teeth  1032  have a clocking associated with them. This clocking is approximately 300 rotation of the inside cogs-teeth  1032  relative to the outside cog-teeth  1031  as represented by the angle between outside cog-teeth  1031  using reference line  1033  and the inside cogs-teeth  1032  using reference line  1034 . This vertical cog-tooth tread-drive hub assembly  1093  has, as an option, the positive sprocket drive gear  1090 , as shown in  FIG. 10G . When viewed from the side the outside cog-teeth  1031  and inside cog-teeth  1032  form a circle around the vertical cog-tooth tread-drive hub assembly  1093  with respect to the outside circumference of the outside cog-teeth  1031  and inside cog-teeth  1032 . This will produce a smooth transition from one cog-tooth to the other. The outside cog-teeth  1031  and the inside cog-teeth  1032  are fastened to the vertical cog-tooth tread-drive hub assembly  1093  with fasteners  1052 . The fasteners  1052  pass through the countersunk through-holes  1058  in the outside cog-teeth  1031  and inside cog-teeth  1032 . The fasteners  1052  secure the outside cog-teeth  1031  and inside cog-teeth  1032  to the vertical cog-tooth tread-drive hub assembly  1093  by screwing into the outside bearing threaded-holes  536  and inside bearing threaded-holes  537 . The vertical cog-tooth tread-drive hub assembly  1093  replaces the wheel hub assembly  599 . Not all of the outside bearing threaded-holes  536  and inside bearing threaded-holes  537  are used to secure outside cog-teeth  1031  and inside cog-teeth  1032  to the vertical cog-tooth tread-drive hub assembly  1093 . The extra unused outside bearing threaded-holes  536  and inside bearing threaded-holes  537  are designated as through-holes  1079  and through-holes  1073 , respectively that can be used to secure motor hub assemblies  590  as shown in  FIGS. 5D and 5E . 
         [0286]    In  FIG. 10N  no motor hub assemblies  590  are incorporated into the vertical cog-tooth tread-drive hub assembly  1093 . However, motor assemblies can be added to the vertical cog-tooth tread-drive hub assembly  1093  as shown in  FIG. 5D . A motor hub assembly  590  can be inserted into one or both of the wheel hubs  556  of the vertical cog-tooth tread-drive hub assemblies  1093 . The motor hub assemblies  590  can be secured to the wheel hubs  556  with longer fasteners  1052  that pass through the countersunk through-holes  1058 , and through the through-holes  1073  and through-holes  1079 . The outside cog-teeth  1031  and the inside cog-teeth  1032  to the vertical cog-tooth tread-drive hub assemblies  1093  with longer fasteners  1052 , which are used to secure the motor hub assembly  590  (see  FIG. 5D ) to vertical cog-tooth tread-drive hub assembly  1093 . Outside bearing through-holes  536  are used to secure the outside bearing  527  of the motor hub assembly  590  (see  FIG. 5D ), whereas inside bearing through-holes  537  of the motor hub assembly  590 , are used to secure inside bearing  530  (see  FIG. 5D ). 
         [0287]      FIG. 10O  is an expanded isometric view of the vertical cog-tooth tread-drive hub assembly  1093 . The new component, the bearing hub adapter assembly  1069 , is shown with bearing recess  1060 , axel through-hole  1062 , protective cap retaining recess  1055 , inner threaded-holes  1057 , and outer threaded-holes  1056 . These inner threaded-holes  1057  and outer threaded-holes  1056  are used to attach the bearing hub adapter  1050  when inserted into the wheel hub  556  of the vertical cog-tooth tread-drive hub assembly  1093 . The axel through-holes  1062 ,  1094 , and  1078  are collinear. This bearing hub adapter  1050  is attached to the vertical cog-tooth tread-drive hub assemblies  1093  with fasteners  1052 . Each cog-tooth has a set of three fastener countersunk through-holes:  1053   a ,  1053   b , and  1053   c  as shown in  FIG. 10Q . The three fastener countersunk through-holes  1053   a ,  1053   b , and  1053   c , and through-holes  537  and through-holes  536 , shown in  FIG. 10P , are used for the fasteners  1052  to fasten the bearing hub adapter  1050 . The fasteners  1052  pass through all of the outer cog-teeth  1031  and inner cog-teeth  1032 , which will securely hold the bearing hub adapter  1050  in place. 
         [0288]      FIG. 10P  is an expanded isometric view of the vertical cog-tooth tread-drive hub assemblies  1093  and the axel-hub adapter assembly  1067 . The axel hub adapter  1051  allows for mounting without the motor hub assemblies  590  incorporated into the wheel hub assemblies  599  as shown in  FIG. 5D . This configuration will allow the bearing spacer  934  and the bearing  930  (not shown, see  FIG. 9B ) to be placed over the hub axel  1068 . The hub axel  1068  has a through-hole  1066  for passing wires for sensors or motors. A protective cap retaining recess  1055  is machined or formed into the sidewall of the hub axle flange  1064 . The axel hub adapter  1051  is mounted internally to the cog-tooth hub assembly  1093  with fasteners  1052  that are screwed through the outside cog-teeth  1031  and the inner cog-teeth  1032 , as shown in the inset in  FIG. 10P  or see  FIG. 10Q , for the full view of this inset. Not all of the outside bearing through-holes  536  and not all of inside bearing through-holes  537  are used to secure outside cog-teeth  1031  and inside cog-teeth  1032  to the cog-tooth hub assembly  1093 . 
         [0289]      FIG. 10Q  is an isometric view of the inset in  FIG. 10O  and  FIG. 10P . The outside cog-teeth  1031  and the inside cog-teeth  1032  have countersunk through-holes  1053   a ,  1053   b , and  1053   c . The countersunk through-holes  1053   a  and  1053   c  are used to secure the tooth to the cog-tooth hub assembly  1093  with fasteners  1052 . The center countersunk through-hole  1053   b  is used to secure one of the two hub adapters: axel hub adapter  1051  or bearing hub adapter  1050  with longer fasteners  1052 . The axel hub adapter  1051  or the bearing hub adapters  1050  are secured fasteners  1052 . Both the outside cog-teeth  1031  and the inside cog-teeth  1032 , which are fastened with fasteners  1052 , can be fastened with an intervening layer of tape, referred to as a sealing band  1030 . This will minimize particulate contamination and mitigate water from entering the hubs directly. This tape serves as an occlusive seal. 
         [0290]      FIG. 10R  is an isometric view of the vertical cog-tread drive assembly  1001 , which is comprised of a vertical cog-tread skin  1088 , a set of axel hub adapter  1051 , a set of bearing hub adapters  1050 , and for each adapter set there is a vertical cog-tooth tread-drive hub assembly  1093 . The vertical cog-tooth tread-drive hub assembly  1093  has a bearing hub adapter  1050  and an axel hub adapter  1051 . The vertical cog-tread skin  1088  has outer cog-tread openings  1040  and inner cog-tread openings  1042 . These outer cog-tread openings  1040  and inner cog-tread openings  1042  engage the outer cog-teeth  1031  and the inner cog-teeth  1032 , respectively. The outer cog-tread openings  1040  and inner cog-tread openings 1042  provide an escape path for the dirt, sand, mud, snow, and ice that might cause the treads to slip. The outer cog-teeth  1031  and the inner cog-teeth  1032  push the debris through these openings. This system provides exceptional transfer of torque to the tread because of the grip of the outer cog-teeth  1031  and the inner cog-teeth  1032  on the outer cog-tread openings  1040  and inner cog-tread openings  1042  and the approximate 30° clocking referred to in  FIG. 10N . This clocking provides a continuous force on the vertical cog-tread skin  1088 . The positive sprocket drive gear  1090  and its respective riser tread guide  1096  are used in this configuration for maximum performance. 
         [0291]      FIG. 11A  is an isometric view of a horizontal cog-hub assembly  1100  with a closed protective cap  1122  that is placed into a closed protective cap-retaining recess  1110 . Rotating about the axis of rotation  1199  on an axle  1130  is the horizontal cog-tread hub assembly  1100 . The horizontal cog-tread hub assembly  1100  is comprised of horizontal cog-teeth  1102  with intervening depressions  1104  that are formed onto and into the oval hubs  1106 . These intervening depressions  1104  are used to prevent tread binding because of debris buildup. These intervening depressions  1104  can help evacuate sand, water, and other debris as the horizontal cog-hub assembly  1100  rotates. The horizontal cog-hub assembly  1100  rotates on bearings  1116  that are secured in place by a locking nut  1120  with a bearing washer  1118 . The locking nut  1120  is fastened onto the axel threaded end  1124  of the axel  1130 . The axel  1130  has two threaded ends  1124 . Also shown is a positive sprocket drive gear  1090  that is inserted between the two oval hubs  1106 . 
         [0292]      FIG. 11B  is an expanded isometric view of the horizontal cog-hub assembly  1100 . This expanded view shows two identical oval hubs  1106  with the horizontal cog-teeth  1102  and the intervening depressions  1104 . The two oval halves  1106  and the positive sprocket drive gear  1090  are joined together with friction fit alignment rods  1091 . These friction fit alignment rods  1091  also register and hold in place the intervening positive sprocket drive gear  1090 . The friction fit alignment rods  1091  are inserted and press fit into the friction fit seating recess 1189  of the one oval hub  1106 , then pass through the through-hole  1092  of the positive sprocket drive gear  1090  and into the friction fit seating recess  1189  of the second oval hub  1106 . The oval hubs  1106  have axel through-hole  1112  and a bearing recess  1114  that will ride on an axel  1130  (not shown, see  FIG. 10A ). The positive sprocket drive gear  1090  also has an axel through-hole  1194  that is larger than the axel through-hole  1112  to prevent binding. The axel through-hole  1194  of the positive sprocket drive gear  1090  can be enlarged to accept a bearing to share axel  1130  loading forces. These parts are pressed together and form the horizontal cog-hub assembly  1100 . The horizontal cog-hub assembly  1100  is designed to ride on axle  1130  as shown in  FIG. 11A . 
         [0293]      FIG. 11C  is an expanded isometric view of the components used to secure the horizontal cog-hub assembly  1100  to the axel  1130 . A portion of the axel  1130  is shown. Beginning from the partial view of the axel  1130 , there is a protective cap  1123  that slides onto the axel  1130  through the through-hole  1126 . This protective cap  1123  will snap into the protective cap retaining recess  1110  to protect the bearing and other surfaces from water and debris intrusion. Flange nut  1125  acting as a flange stop is threaded onto the axel threaded end  1124  of the axel  1130  and locked in place with the locking nut  1105 . The bearing washer  1118  is positioned onto the axel  1130  next to the locking nut  1105 . The bearing  1116  and the bearing spacer  1111  are positioned onto the axel  1130  and simultaneously inserted into the bearing recess  1114  of the horizontal cog-hub assembly  1100 . The axel threaded end  1124  of the axel  1130  will protrude from the axel through-hole  1112  of the second oval hub  1106  allowing the bearing spacer  1111  and the bearing  1116  to be seated in the bearing recess  1114  of oval hub  1106 . To complete the assembly process, the horizontal cog-hub assembly  1100  is secured to the axel  1130  by adding the last bearing washer  1118  and the locking nut  1120  onto the axel threaded end  1124  of the axel  1130 . The closed protective cap  1122  is installed into the cover retaining recess  1110  to minimize contamination. 
         [0294]      FIG. 11D  is an isometric view of the horizontal cog-tread  1150 . This view shows the horizontal cog-teeth tread openings  1108 , the inside surface  1002 , the tread riser guide  1096 , and the receiver sprocket  1098 . All of these components and their functions will be described in the  FIG. 11E . 
         [0295]      FIG. 11E  is an isometric view of the horizontal cog-tread  1150  and the horizontal cog-hub assemblies  1100  that comprise the horizontal cog-drive assembly  1160 . As the horizontal cog-hub assemblies  1100  begin to rotate, the horizontal cog-teeth  1102  will engage horizontal cog-teeth tread openings 1108  moving the horizontal cog-tread  1150  forward. If there were any debris in the horizontal cog-teeth tread openings 1108 , the horizontal cog-tooth  1102  expels the debris. As the horizontal cog-tread  1150  moves around the horizontal cog-hub assemblies  1100 , the horizontal cog-teeth  1102  will disengage the horizontal cog-teeth tread openings  108 . These horizontal cog-teeth tread openings  1108  will act to grip mud, dirt, and grass to maintain traction until it engages the other horizontal cog-hub assemblies  1100  and continues the process. Another traction device that is implemented in this configuration is the positive sprocket drive gear  1090  (not shown, see  FIG. 11B ) that couples to the receiver sprocket  1098  of the tread riser guide  1096 . The tread riser guide  1096  also prevents the horizontal cog-tread  1150  from slipping off the horizontal cog-hub assemblies  1100 . The horizontal cog-teeth  1102  prevent the horizontal cog-tread  1150  from slipping off the horizontal cog-hub assemblies  1100 . The inside surface  1002  of the horizontal cog-teeth tread openings  1108  should be filleted to prevent the horizontal cog-teeth  1102  from riding up onto the inside surface  1002  of the horizontal cog-tread  1150 , which would cause jamming and derailment of horizontal cog-tread  1150 . The closed protective caps  1122  that normally reside on the vertical hub surface at  1110  have been removed to show the recessed bearings  1116 . 
         [0296]      FIG. 12A  is a side view of the treaded cooler assembly  1200 , the pulling handle assembly  1201 , and the horizontal cog-tread drive assembly  1160  that is comprised of the horizontal cog-hub assembly  1100  and the horizontal cog-tread  1150 . The treaded cooler assembly  1200  is comprised of a cooler top  1202 , a cooler body  1204 , a cooler base  1208 , the horizontal cog-hub assembly  1100 , the horizontal cog-tread  1150 , and a pulling handle assembly  1201 . The cooler top  1202  has a recessed handle  1212  that is accessed through a recessed finger pull  1210 . The recessed handle  1212  resides in the recessed handle pocket  1214 . Cooler body  1204  sits atop a cooler base  1208 . This cooler base  1208  has rigid forks  1207  that are formed by a molding, thermoforming or metal forging process. The cooler body  1204  can be welded, fused or glued to the cooler base  1208  as indicated by the bond bead or weld bead  1206 . The horizontal cog-hub assembly  1100  is attached to the rigid forks  1207  of the cooler base  1208 . The horizontal cog-hub assembly  1100  drives the horizontal cog-tread  1150 . The pulling handle assembly  1201  maneuvers the cooler base  1208 . The pulling handle assembly  1201  is comprised of a D-handle  1226 , a T-union  1236 , a handle arm  1228 , and a second T-union  1236 . The pulling handle assembly  1201  is connected to the cooler base  1208  by the axel hinge-pin  1230  and a quick disconnect pin  1232  (not shown). 
         [0297]      FIG. 12B  is an isometric view of the treaded cooler assembly  1200 , the pulling handle assembly  1201 , and the dual horizontal cog-tread drive assembly  1160 . The dual horizontal cog-tread drive assembly  1160  is comprised of a longer axel  1130  (not shown, see  FIG. 11C ) and multiple hub spacers  1119  to adequately separate the two horizontal cog-hub assemblies  1160 . 
         [0298]    This view shows the side recessed cooler handle  1215  that is recessed into the side recessed cooler handle pocket  1216  and a fortified side recessed frame  1218  that distributes the forces of the full cooler load across the cooler side wall when the cooler body  1204  is lifted. This force redistribution will allow the cooler body  1204  and cooler top  1202  to be removed from the cooler base  1208  if it is not welded or bonded. The cooler body  1204  can be, for example, welded, fused, strapped, or glued to the cooler base  1208  as indicated by the bond bead or weld bead  1206 , which secures the cooler body  1204  to the cooler base  1208  providing maneuverability as a single monolithic body. This is another reason for strengthening the fortified side recessed frame  1218 . This view shows the pulling handle assembly  1201 . This view shows the D-handle  1226  inserted into the T-union  1236  and how the D-handle  1226  rotates about the axis of rotation  1225 . The pulling handle assembly  1201  is connected to the cooler base  1208  by the axel hinge-pin  1230  that slides through the hollow hinge knuckle  1234  through the T-union  1236  and the second hollow hinge knuckle  1234 . The axel hinge-pin  1230  also serves as a hinge-pin and passes through the two hollow hinge knuckles  1234 . The pulling handle assembly  1201  can be duplicated or relocated from one end of the cooler to the other by pulling the quick disconnect pin  1232  from the locking pin through-hole  1233 , and then removing the axel hinge-pin  1230  by the elbow finger-pull  1238 . The axel hinge-pin  1230  is joined to identical hardware on the opposite end of the treaded cooler assembly  1200 . This treaded cooler assembly  1200  uses two of the horizontal cog-tread drive assemblies  1160  as shown in  FIG. 11E . The tread hub assemblies  1100  are attached to the rigid fork  1207  at each end of the cooler base  1208  with a long axel, which is axel  1130  in  FIG. 11C . 
         [0299]      FIG. 12C  is an expanded isometric view of the cooler top  1202 , cooler body  1204 , cooler base  1208 , a cooler base reinforcement plate  1220 , and the pulling handle assembly  1201 . The cooler top  1202 , the cooler body  1204 , and the side recessed cooler handle  1215  are shown elevated above the cooler base  1208 . The dashed line  1206  represents the bond-line or weld-line if the cooler body  1204  is to be permanently fixed to the cooler base  1208 . The dashed line  1206  represents the footprint of the cooler body  1204  as temporarily seated on the cooler base  1208  if strapped in place. 
         [0300]    Common plastic materials used to make coolers would be inadequate for the forces required to pull large coolers. Therefore, cooler base reinforcement plate  1220  is generally, but not always a metal structure that is fastened to the underside of the cooler base  1208 . The cooler base reinforcement plate  1220  is fastened to the underside of the cooler base  1208  with bolts  1242 . The bolts  1242  pass through the bolt through-holes  1240  and are threaded into the underside threaded-holes  1243  (not shown) of the cooler base  1208 . Two hollow hinge knuckles  1234  are on opposite ends of the cooler base reinforcement plate  1220 . These are called “knuckles” according to hinge anatomy and the “hinge-pin” is the axel-rod hinge-pin  1230 . The two hollow hinge knuckles  1234  are welded or formed in place will function as a strong point for pulling. This will eliminate strong localized forces applied to the plastic. The axel-rod hinge-pin assembly  1203  is comprised of an axel-rod hinge-pin  1230 , the hollow hinge knuckle  1234 , the T-union  1236 , the last hollow hinge knuckle  1234 , a locking pin through-hole  1233 , the elbow finger-pull  1238 , and a quick disconnect-pin  1232 . The axel-rod hinge-pin assembly  1203  uses the axel hinge-pin  1230  that passes through the hollow hinge knuckle  1234 , the T-union  1236 , and the last hollow hinge knuckle  1234  to form a hinge-like assembly, which the handle pulling assembly  1201  is free to rotate. To prevent the axel hinge-pin  1230  from sliding out, there is a locking pin through-hole  1233  in the end opposite the elbow finger-pull  1238 , that will receive a quick disconnect-pin  1232 . This forms a rigid structure that will be strong enough to withstand the pulling pressures of a fully loaded cooler. 
         [0301]      FIG. 12D  is an expanded side view of a peg-leg cooler body  1246  that will be lowered onto the peg-leg cooler base  1248  and form the peg-leg cooler  1294 . The peg-leg cooler body  1246  is identical to the cooler body  1204  but has cooler peg-legs  1250  formed or welded to the underside of the cooler body  1204 . The peg-leg cooler base  1248  has on each side an array of cooler base peg-leg access holes  1256 . These cooler base peg-leg access holes  1256  receive the cooler peg-legs  1250  that attach to the peg-leg cooler base  1248  by inserting them into the cooler base peg-leg access holes  1256 . This peg-leg cooler body  1246  is held in place by cooler base quick disconnect locking pins  1258  that pass through the cooler base quick disconnect locking pin through-hole  1254  in the peg-leg cooler base  1248  and through the peg-leg quick disconnect locking pin through-holes  1252  that are machined or formed into the cooler peg-legs  1250 . This forms a secure peg-leg cooler assembly  1295  that will act as a monolithic body. The same assembly method used in  FIG. 12C  of the cooler base reinforcement plate  1220 , the axel-rod hinge-pin assembly  1203 , and handle pulling assembly  1201  of the cooler base  1208 , as shown in  FIG. 12C , are used to construct the peg-leg cooler base  1248 . In order to withstand the pulling forces due to the heavy weight of the contents of the cooler the reinforcement structure is necessary if plastic parts are used. 
         [0302]      FIG. 12E  is an expanded isometric view of the peg-leg cooler  1294  and the peg-leg cooler base  1248  with a dashed line inset that will show a closer view of the cooler peg-leg  1250  and the cooler base quick disconnect locking pins  1258  interaction. This figure shows the cooler base peg-leg quick disconnect locking pins  1258  ready to be inserted into their respective through-holes once the peg-leg cooler body  1246  has been set in place. Once the peg-leg cooler body  1246  is properly seated on the peg-leg cooler base  1248  by sliding the cooler peg-legs  1250  into the cooler base peg-leg access holes  1256 , the cooler base quick disconnect locking pins  1258  may be inserted into quick disconnect locking pin through-hole  1254  in the peg-leg cooler base  1248 , and through the peg-leg quick disconnect locking pin through-holes  1252  that are machined or formed into the cooler peg-legs  1250  to secure the peg-leg cooler body  1246  onto the peg-leg cooler base  1248 . 
         [0303]      FIG. 12F  is an expanded isometric view of the dashed line inset from  FIG. 12E  showing an enlarged view of the cooler peg-leg  1250  and a closer partial view of the axel-rod hinge-pin assembly  1231 . The peg-leg cooler body  1246  is properly seated on the peg-leg cooler base  1248  by sliding the cooler peg-legs  1250  into the cooler base peg-leg access holes  1256 , inserting the cooler base quick disconnect locking pins  1258  into the cooler base quick disconnect locking pin through-hole  1254  in the peg-leg cooler base  1248 , and through the peg-leg quick disconnect locking pin through-holes  1252  that are machined or formed into the cooler peg-legs  1250  to secure the peg-leg cooler body  1246  onto the peg-leg cooler base  1248 . The cooler base quick disconnect locking pins  1258  extend further into the peg-leg cooler base  1248  by seating deeper into the extended through-hole  1253 . 
         [0304]    This view also shows the axel-rod hinge-pin assembly  1231 . The handle arm  1228  is connected to the lower T-union  1236 . This lower T-union  1236  is held in place between the two hollow hinge knuckles  1234 , and acts like a hinge once the axel hinge-pin  1230  is slid into the hollow hinge knuckles  1234  that are attached to the cooler base reinforcement plate  1220 . The T-union  1236  is captured between the hollow hinge knuckles  1234 , and the axel hinge-pin  1230  is locked into position by a quick disconnect pin  1232  that is placed into a locking pin through-hole  1233 . 
         [0305]      FIG. 12G  is the assembled isometric view of the peg-leg cooler assembly  1295 , peg-leg cooler  1294  and the two horizontal cog-tread assemblies  1160 . These items comprise the dual horizontal cog-tooth treaded drive peg-led cooler assembly  1299 . 
         [0306]      FIG. 12H  is an expanded isometric view of the two horizontal cog-tread drive assemblies  1160 , which are separated by hub spacers  1119 , and are fastened to the rigid fork  1207  of cooler base  1208 . The cooler base  1208  is lowered over the two horizontal cog-tread drive assemblies  1160 , which are separated by hub spacers  1119 . The cooler base  1208  has rigid forks  1207  with fork-axel through-holes  1224  that accept the axel threaded end  1124  of the axel  1130  (not seen, see  FIG. 11C ), and passes through the two horizontal cog-tread drive assemblies  1160 , as described in  FIG. 11E , but has a large hub spacer  1119  that separates the two horizontal cog-tread drive assemblies  1160 , and serves as a protective cap  1123  that keeps the internal bearings  1116  debris free. The axel threaded end  1124  passes through the other fork axel through-hole  1224  of the cooler base  1208 , and is fastened in place with the locking-nut  1120  threaded onto the axel threaded end  1124 , and covered with the small closed protective cap  1122  by snapping or threading onto the axel threaded end  1124 . 
         [0307]      FIG. 12I  is an isometric view of the peg-leg cooler assembly  1295  with a wide horizontal cog-tread  1290 . This view shows wide horizontal cog-tread  1290  that has three tread risers: left tread riser  1286 , center tread riser  1287 , and right tread riser  1288 , and has two horizontal cog-tooth hubs  1100  on each axle  1130  (not shown, see  FIG. 11C ). This additional center tread riser  1287  provides stability to the wide horizontal cog-tread  1290 . The center tread riser  1287  constrains the wide tread opening  1289  to a constant size preventing it from deforming. This deformation would result in the cog-tooth  1102  missing the wide tread opening  1289  of the wide horizontal cog-tread  1290  derailing from the horizontal cog-tooth hubs  1100 . The action of pulling the treaded vehicle forward with large mass on the cooler, would cause partial collapse of the middle portion of the horizontal cog-teeth tread openings  1108 . Therefore, this additional tread offers more stability. 
         [0308]      FIG. 12J  is an expanded isometric view of the wide horizontal cog-hub assembly  1297  with a wide positive sprocket drive gear  1270  incorporated between the two horizontal cog-hub assemblies  1100 . Two horizontal cog-hub assemblies  1100  are joined together with an intervening wide positive sprocket drive gear  1270 . On both sides of the wide positive sprocket drive gear  1270  is a bearing recess  1274  and an axle through-hole  1272 . The two horizontal cog-hub assemblies  1100  and a wide positive sprocket drive gear  1270  are held together by friction fit alignment rods  1278  that are passed through the alignment rod through-holes  1276  in the wide positive sprocket drive gear  1270 . These friction fit alignment rods  1278  mate into friction fit receiver-hole  1262  that are machined or formed into the inside surface  1260  of both oval hubs  1106 . The bearings  1268  fit into bearing recesses  1274  on both sides of the wide positive sprocket drive gear  1270 . The oval tread hubs  1106  have inside surfaces  1260 , a bearing recess  1114 , axle through-hole  1112 , and four friction fit receiver-holes  1262 . The bearings  1268  and bearing spacers  1266  are sandwiched between the wide positive sprocket drive gear  1270  and their respective tread hub assemblies  1100 . The outside oval hubs  1106  have bearing recesses  1114  and axel through-holes  1112 . The bearing  1116  and bearing spacer  1111  are inserted into the bearing recess  1114 . The left positive sprocket drive gear  1280 , the center wide positive sprocket drive gear  1270 , and the right positive sprocket drive gear  1284  are the respective drive gears for the left tread riser  1286 , center tread riser  1287 , and right tread riser  1288  as shown in  FIG. 12I . 
         [0309]      FIG. 12K  is an off-axis view of the completed wide tread hub assembly  1297  with the left positive sprocket drive gear  1280 , the center wide positive sprocket drive gear  1270 , and the right positive sprocket drive gear  1284 . 
         [0310]      FIG. 12L  is an off-axis view of the wide tread  1290 . This view shows three risers incorporated as internal structures to the wide tread  1290 . These risers are left tread riser  1286 , center tread riser  1287 , and right tread riser  1288 . They engaged their respective positive sprocket drive gears: the left positive sprocket drive gear  1280 , the center wide positive sprocket drive gear  1270 , and the right positive sprocket drive gear  1284 . 
         [0311]      FIG. 12M  is an off-axis low-level view of a peg-leg seat  1296  that replaced the peg-leg cooler  1294  in  FIG. 12D . This view shows the respective positive sprocket drive gears: the left positive sprocket drive gear  1280 , the center wide positive sprocket drive gear  1270 , and the right positive sprocket drive gear  1284  incorporated into the wide tread hub assembly  1297  that is engaging the respective tread risers: the left tread riser  1286 , center tread riser  1287 , and right tread riser  1288 . The peg-leg seat  1296  is an example of the versatility of the treaded peg-leg cooler assembly  1295 . Other structures can be created as add-on features to this style of peg leg cooler  1294 . 
         [0312]      FIG. 13A  is an isometric view of the outrigger treaded transport base  1300 , cooler body  1204 , cooler top  1202 , the pulling handle assembly  1201 , the axel-rod hinge-pin assembly  1203 , and the horizontal cog-tread drive assembly  1160 . The cooler body  1204  can be, for example, glued, welded, bolted or Velcro to the surface of the outrigger treaded transport  1300 . The horizontal cog-tread drive assembly  1160  uses the horizontal cog-tread  1150  and the horizontal cog-hub assemblies  1100  that are mounted onto the axel  1130 . 
         [0313]      FIG. 13B  is an isometric view of the outrigger treaded transport base  1300  and the horizontal cog-tread drive assembly  1160  without the cooler body  1204  and the cooler top  1202 . The monolithic outrigger treaded transport base  1300  is comprised of two fenders  1302  and fender risers  1304  that support the fenders  1302 . The fenders  1302  act as shields to prevent entanglement with clothing or flying debris from the horizontal cog-tread drive assembly  1160 . The horizontal cog-tread drive assembly  1160  and components used have been described in  FIG. 1E . 
         [0314]      FIG. 13C  is an expanded isometric view of the parts that comprise the treaded transporter assembly  1301 , which are the monolithic outrigger treaded transport base  1300 , the cooler base reinforcement plate  1220 , and a tread transporter-mounting base  1310 . The tread transporter-mounting base  1310  has a geometry recess that is called the base plate recess  1312  on the top surface that matches the geometry of the cooler base reinforcement plate  1220 . The cooler base reinforcement plate  1220  fits tightly into the base plate recess  1312 , and serves as a strong support structure that is sandwiched between other components such as outrigger treaded transport base  1300  and the tread transporter-mounting base  1310 . When combined, the treaded transporter assembly  1301  can sustain the pulling forces of the weight of the cargo that will be carried/transported. Metal is the preferred material for the cooler base reinforcement plate  1220 , although other materials can be used such as Kevlar® plate, carbon fiber plates or other robust materials. Metal is preferred because at the end edges of the cooler base reinforcement plate  1220  there are two tube-like structures called hollow hinge knuckles  1234  that are easily formed and can withstand higher pulling forces and not break. 
         [0315]    The treaded transporter assembly  1301  is assembled in the following manner: the tread transporter-mounting base  1310  will have lowered into its base plate recess  1312 , the cooler base reinforcement plate  1220 . The outrigger transport base  1300  will be lowered onto the cooler base reinforcement plate  1220  and flush with the tread transporter-mounting base  1310 . The four short bolts  1322 , on either end of the outrigger treaded transport base  1300 , will then be screwed into the tread transporter-mounting base  1310  after passing through the countersunk through-holes  1324 , through the through-holes  1244  of the cooler base reinforcement plate  1220 , and into the threaded through-holes  1318 . These short bolts  1322  need to be shorter to fit within the beveled leading edge  1352  of the front and rear of the tread transporter-mounting base  1310 . The remaining longer bolts  1320  of the outrigger treaded transport base  1300  are screwed into the tread transporter-mounting base  1310  after passing through the countersunk through-holes  1324 , through the through-holes  1244  of the cooler base reinforcement plate  1220 , and into the deeper threaded through-holes  1316 . Next, the transporter axles  1340  are slid through the elongated through-holes  1332  of the tread transporter-mounting base  1310  that have been elongated to allow tensioning block  1330  to also fit into the elongated through-holes  1332 . The horizontal cog-tread drive assemblies  1160  (not shown, see  FIG. 13B ) will be tightened by the action of a tensioning block  1330  once it is positioned in the elongated through-hole  1332  to mate up with the tensioning bolt  1334 . 
         [0316]      FIG. 13D  is an isometric view of the transporter axle  1340 , the tensioning blocks  1330 , the tensioning bolts  1334 , stop washers  1336 , and a tensioning bolt through-hole  1344 . The tensioning bolt through-hole  1344  is perpendicular to the axel  1340 . This is a view of the components within the tread transporter-mounting base  1310 , and with the tread transporter-mounting base  1310  made invisible. The tensioning bolt  1334  with the stop washer  1336  passes through the tensioning bolt through-hole  1344 . The tensioning bolt  1334  is introduced to the tensioning block  1330  by threading into the threaded through-hole  1348 . The tensioning bolts  1334 , stop washers  1336 , tensioning bolt through-hole  1344 , and the threaded through-hole  1348  of the tensioning block  1330  all lie on the common alignment axis  1350 . The threaded axle ends  1342  are long to accommodate the horizontal cop-tread drive assemblies  1160  (not shown). The transporter axle  1340  may be hollow to accommodate electrical wires or a solid rod depending upon the load requirements and size of the coolers or accessories carried on the treaded transporter. 
         [0317]      FIG. 13E  is an isometric view of the tread transporter-mounting base  1310  and the associated parts that involve the management of the tread transporter axle  1340 , and an inset view to be described in  FIG. 13  F. In this view the transporter axle  1340  is mounted in the elongated through-holes  1332  of the tread transporter-mounting base  1310  with the tension block  1330 . 
         [0318]      FIG. 13F  is an enlarged view of the inset region of  FIG. 13E . It is an isometric view of the tensioning block  1330 , which will be pulled tight by the tensioning bolt  1334 . The threaded end  1335  of the tensioning bolt  1334  and the stop washer  1336  are inserted into the countersunk through-hole  1338  on the beveled leading edge  1352  of the tread transporter-mounting base  1310 . The threaded end  1335  of the tensioning bolt  1334 , threads into the threaded through-hole  1348  of the tensioning block  1330 . The tensioning bolt  1334  uses the stop washer  1336  to apply uniform force around the countersunk stop hole  1326 . Once the stop washer  1336  and tensioning bolt  1334  meet at countersunk stop hole  1326 , the tensioning bolt  1334  continuously tightens until it pulls the tensioning block  1330  and engages the concave axel mating face  1339  with the outside face of the transporter axle  1340 . Tightening continues and tension will build in the horizontal cog-tread drive assembly  1160  (not shown, see  FIG. 13B ) until the horizontal cog-tread  1150  is taut. The tensioning bolt  1334  should never reach the point where it pulls the transporter axle  1340  firmly up against the end-wall of the elongated through-hole  1332 . The properly designed system will have some space between the transporter axle  1340  and the end-wall of the elongated through-hole  1332 . 
         [0319]    The cross-section shows the material removed from the cooler base as the crosshatched regions of  1362 . The beveled leading edge  1352  of the tread transporter-mounting base  1310  acts as a plow. Since the tread transporter-mounting base  1310  will be used in environments where there is sand, mud, snow, and other kinds of debris, the function of the beveled leading edge  1352  is to push the material down and lift the cooler up. If the sand or snow is too deep, this helps reduce the pulling force required to move forward.

         [0333]      FIG. 15E  is an isometric front view of the completed axel-hub-adapter fork-truck assembly  1500 . 
         [0334]      FIG. 16A  is an isometric view of a solid fork tine  1610 . This solid fork tine  1610  has a solid fork arm  1604  that extends from the hub through-hole  1606  to an axel through-hole  1608 . There are six countersunk through-holes  1602 . 
         [0335]      FIG. 16B  is an isometric view of a modified solid fork tine  1620 . The modified solid fork tine  1620  has a solid fork arm  1604  that extends from the hub through-hole  1606  to an axel through-hole  1608 , and the end of the solid fork arm  1604  is modified with a recess  1612 . There are six countersunk through-holes  1602 . 
         [0336]      FIG. 16C  is an upper isometric view of a shock-absorbing fork tine  1630 . The shock-absorbing fork tine  1630  has a fork arm  1632  that extends from the hub through-hole  1606  to an axel through-hole  1608 . There are six countersunk through-holes  1602 . Nearly identical to solid fork tine  1610  and the modified solid fork tine  1620 , this shock-absorbing fork tine  1630  has an array of geometries that act as a Compound Monolithic Scissor Spring (CMSS), CMSS 1  through CMSS 6 . The rotation point  1637 , of the spring CMSS 1 , is formed by the circular through-hole  1638  and the large rectangular through-hole  1636 , which extend through the entire thickness of fork arm  1632 . There is a smaller rectangular through-hole  1639  at the top of the circular through-hole  1638 . The rotation stop edges  1635  of the large rectangular through-hole  1636  and the rotation stop edge  1633  of the small rectangular through-hole  1639 , serve as rotation stops. When an upward force  1634  is applied to the shock-absorbing fork tine  1630 , a rotation or deflection occurs about the rotation point  1637  in a counter-clockwise direction. If the force is very large, the counter-clockwise rotation will continue until the rotation stop edge  1633  is fully closed and the rotation is transferred to the next element in the CMSS array (CMSS 1  through CMSS 6 ). When a downward force  1634  is applied to the shock-absorbing fork tine  1630 , a rotation or deflection occurs about the rotation point  1637  in a clockwise direction. If the force is very large, the clockwise rotation will continue until the rotation stop edges  1635  is fully closed and the rotation is transferred to the next element in the CMSS array (CMSS 1  through CMSS 6 ). The work done in the rotatory motion or deflective motion of the CMSS array (CMSS 1  through CMSS 6 ) dissipates the shock of bumps encountered during the ride. 
         [0337]      FIG. 16D  is an upper isometric view of a modified shock-absorbing fork tine  1640 . The modified shock-absorbing fork tine  1640  has a fork arm  1632  that extends from the hub through-hole  1606  to an axel through-hole  1608 . The modified shock-absorbing fork tine  1640  has a recess  1642  at the end of fork arm  1632 . There are six countersunk through-holes  1602 . The modified shock-absorbing fork tine  1640  is identical to the shock-absorbing fork tine  1630  in  FIG. 16C . 
         [0338]      FIG. 16E  is an elevated isometric view of the solid dual fork tine  1650 . The fork arms  1652  support two axels (not shown) that use through-holes  1608 .

This modified solid dual fork tine  1660  has two fork arms  1661  that extend from the hub through-hole  1606  to each axel through-hole  1608  and a recess 1662 . There are six countersunk through-holes  1602 . 
         [0340]      FIG. 16G  is an elevated side view of the dual shock-absorbing dual-fork tine  1670 . The dual shock-absorbing dual-fork tine  1670  has two fork arms  1671  that extend from the hub through-hole  1606  to each axel through-hole  1608 . There are six countersunk through-holes  1602 . The function of the dual shock-absorbing dual-fork tine  1670  is identical to shock-absorbing fork tine  1630  described in  FIG. 16C . This dual shock-absorbing dual-fork tine  1670  has an array of geometries on each fork arm  1671  that act as a Compound Monolithic Scissor Spring (CMSS), CMSS 1  through CMSS 8 . The rotation point  1637 , of the spring CMSS 1 , is formed by the circular through-hole  1638  and the large rectangular through-hole  1636 , which extend through the entire thickness of fork arm  1632 . There is a smaller rectangular through-hole  1639  at the top of the circular through-hole  1638 . The rotation stop edges  1635  of the large rectangular through-hole  1636  and the rotation stop edges  1633  of the small rectangular through-hole  1639 , serve as rotation stops. When an upward force  1634  is applied to the dual shock-absorbing dual-fork tine  1670 , a rotation or deflection occurs about the rotation point  1637  in a counter-clockwise direction. If the force is very large, the counter-clockwise rotation will continue until the rotation stop  1633  is fully closed and the rotation is transferred to the next element in the CMSS array (CMSS 1  through CMSS 8 ). When a downward force  1634  is applied to the shock-absorbing fork tine  1630 , a rotation or deflection occurs about the rotation point  1637  in a clockwise direction. If the force is very large, the clockwise rotation will continue until the rotation stop edge  1635  is fully closed and the rotation is transferred to the next element in the CMSS array (CMSS 1  through CMSS 8 ). The work done in the rotatory motion or deflective motion of the CMSS array (CMSS 1  through CMSS 8 ) dissipates the shock of bumps encountered during the ride. The counter clockwise rotation applies to the forward fork arm  1671 ; the opposite fork arm  1671  will rotate in the clockwise direction. 
         [0341]      FIG. 16H  is a lower side view of the modified dual shock-absorbing dual-fork tine  1680 .

The modified dual shock-absorbing dual-fork tine  1680  has a recess  1685  at each end of fork arm  1681 . There are six countersunk through-holes  1602 . The function of the modified dual shock-absorbing dual-fork tine  1680  is identical to dual shock-absorbing dual-fork tine  1670  described in  FIG. 16G . 
         [0342]      FIG. 17A  is an expanded side view of the single wheel axel assembly  1700 , the axel-hub-adapter fork-truck assembly  1500 , and the modified shock-absorbing fork tines  1640 . The assembly is made from all of the components shown in  FIG. 17A  that are in the 1700 number grouping. The wheel  1701  has an axel  1714  that passes through the axel through-hole  1718 . On the axel  1714  there is a washer  1712  that separates the bearing  1708  from the wheel  1701  that resides in the bearing recess  1716 . The axel  1714  passes through the axel through-hole  1608  of the modified shock-absorbing fork tine  1640 . To prevent friction of the bearing  1708  and the inside wall of the modified shock-absorbing fork tine  1640 , there is another washer  1706  that slides on to the axel  1714 . The axel  1714 , wheel  1701 , and the other mounting components are secured in place with the washer  1704  and locking nut  1702 . The locking nut  1702  and washer  1704  are tightened onto the threaded end  1710  of the axel  1714  in the recess  1642 . Prior to the assembly of the wheel axel assembly  1700 , the modified shock-absorbing fork tines  1640  are fastened to the axel-hub-adapter fork-truck assembly  1500 . Other fork tines can be used; however, for this example, the modified shock-absorbing fork tines  1640  were chosen. The modified shock absorbing fork tines  1640  are fastened onto the hub adapter  1520  by sliding the fork through-hole  1606  onto the hub adapters  1520  and secured in place by passing fasteners  1605  that pass through the countersunk through-holes  1602  and tightening them into the threaded-holes  1526 .

This view references the single wheel axel assembly  1700  before a reconfiguration of the single wheel axel assembly  1700  and modified shock-absorbing fork tines  1640 . The fasteners  1605  have been withdrawn to accomplish a rotation of the modified shock-absorbing fork tines  1640  about the monolithic hub axel ends  1424 , the center of which is indicated by the end  1790  of the dashed reference line  1792 . The other end of the dashed reference line  1792  is endpoint  1793  (start) and coincident to the center point of the threaded end  1710  of axel  1714  and the radius point that will be rotating about the monolithic hub axel ends  1424 . Note the fasteners  1605  clocking orientation in this example. There can be many different clocking angles for the orientation of the modified shock-absorbing fork tines  1640 . In this illustration the clocking angles are approximately in 36° increments. 
         [0346]      FIG. 17E  shows the side view as the modified shock-absorbing forks tines  1640  are rotated one clocking increment of approximately 36° from its original position as indicated by the endpoint  1793  (finish) of the dashed reference line  1792 . The fasteners  1605  can be secured into the threaded-holes  1426  at this point fixing in place the modified shock-absorbing fork tines  1640  to the monolithic hub axel ends  1424  and the skateboard ride would be elevated. 
         [0347]      FIG. 17F  is the side view showing the 180° rotation, represented by the dashed arrow, of the modified shock absorbing fork tines  1640  with the single wheel axel assembly  1700  about the center point  1790  of the monolithic hub axel ends  1424 , from the endpoint  1793  (start) to the endpoint (finish), which is part of monolithic axel-hub fork-truck assembly  1400 .

         [0368]      FIG. 21A  is an isometric view of a simple reconfigurable hanger system  2190  that incorporates the use of the fork arm  2116  secured with bolts  2123   a  and bolts  2125   a . The versatility of the simple reconfigurable hanger system  2190  arises from the fact that larger wheels can be used by placing large or small stand-off washers (not shown) on the bolts  2123   a  and  2125   a , or longer fork arms  2116  can be used that have a larger separation between the axel through-hole  2118  and the through-hole  2121   b . Longer bolts  2123   a  and  2125   a  may be required for wider wheels. This view shows the reconfigurable monolithic hanger body  2112  with a threaded-hole  2108 , which functions as a seat for the adjustable pivot pin  2104 . The height of the adjustable pivot pin  2104  can be adjusted by inserting the threaded section  2106  of the adjustable pivot pin  2104  into the threads of the threaded-hole  2108  of the reconfigurable monolithic hanger body  2112 . The adjustable pivot pin  2104  is adjusted with a wrench that uses the adjustable pivot pin flats  2105  on the sides of the adjustable pivot pin  2104 . Adjusting the adjustable pivot pin  2104  will help center the kingpin  2130  (not shown) within the kingpin through-hole  2110 . A wheel recess contour  2122  makes the reconfigurable monolithic hanger body  2112  more compact. Fork arms  2116  are attached to the reference face  2113  with bolts  2123   a  and bolts  2125   a  that pass through the through-holes  2121   a  and through-holes  2121   b , respectively, and are tightened to the threaded-holes  2124  and the threaded-holes  2126 , respectively. The fork arms  2116  have axel through-holes  2118  located at the far end. The axel through-holes  2118  are used to mount the wheel axel assembly  1700  and wheel  1701  shown in  FIG. 20E . The wheel recess contour  2122  provides a compact design by allowing the wheel assembly  1700  and wheel  1701  (not shown) to be mounted closer on shorter fork arms  2116 . The simple reconfigurable hanger system  2190  is illustrated by the use of the bolts  2123   a  and  2125   a.    
         [0369]      FIG. 21B  is an isometric view of a simple reconfigurable hanger system  2180  that incorporates the use of the fork arm  2116 , which is identical in all respects to  FIG. 21A , with the substitution of the double threaded lag-bolts  2123   b  for the bolt  2123   a , and the double threaded lag-bolt  2125   b  substituted for the bolt  2125   a . The versatility of the simple reconfigurable hanger system  2180  arises from the fact that larger wheels can be used by placing large or small stand-off washers (not shown) on the double threaded lag-bolt  2123   b  and double threaded lag-bolt  2125   b  between fork arms  2116  and the reference face  2113 , or longer fork arms  2116  can be used that have a larger separation between the axel through-hole  2118  and the through-hole  2121   b . Larger double threaded lag-bolt  2123   b  and double threaded lag-bolt  2125   b  may be required for larger wheels. The double threaded lag-bolts  2123   b  and double threaded lag-bolts  2125   b  use the same threaded-holes  2124  and threaded-holes  2126 , respectively. The double threaded lag-bolts  2123   b  and double threaded lag-bolts  2125   b  require washers  2119  and locking nuts  2120  to fasten the fork arms  2116  securely to the reference face  2113  of the reconfigurable monolithic hanger body  2112 . The simple reconfigurable hanger system  2180  is distinguished from the simple reconfigurable hanger system  2190  by the double threaded lag-bolt  2123   b  and double threaded lag-bolt  2125   b.

         [0383]    The slot  2312  allows leaf spring action to propagate along the leaf spring fork arm  2316 . The leaf spring fork arms  2316  has five through-holes  2319  along most of its length and four spring dampening through-holes  2314   a ,  2314   b ,  2314   c  and  2314   d  on the left side and the right side along the slot  2312  of each leaf spring fork arm  2316 . 
         [0384]      FIG. 23C  is a top view of the formed fork hanger  2380 . This overview shows the U-channel leaf spring  2385  formed by the U-channel cutout  2383 . The parallel rows of spring dampening through-holes  2384   a ,  2384   b ,  2384   c ,  2384   d  and  2384   e  are control points that constrain the movement of the U-channel leaf spring  2385 . The U-channel leaf spring  2385  has adjustable or controllable flexing points as determined by the placement of spring dampening bolts  2387  and a corresponding spring dampening locking nuts  2388 . The spring dampening bolts  2387  are inserted into the spring dampening through-holes  2384   e  on both sides of the U-channel  2383  and tightened with the spring dampening locking nuts  2388  from the other side. If the spring dampening bolts  2387  and the spring dampening locking nuts  2388  are fastened tightly, there is no movement as in the case of  FIG. 23C . However, if spring dampening bolts  2387  and spring dampening locking nuts  2388  are fastened together loosely, the space that separates them will determine the U-channel leaf spring  2385  maximum excursions. Consequently, by selecting the higher spring dampening through-hole positions such as  2384   d ,  2384   c ,  2384   b , or  2384   a , this will provide controlled U-channel leaf spring  2385  excursions. If there are no spring dampening bolts  2387  and no spring dampening locking nuts  2388  implemented, then the pivot axis of the U-channel leaf spring  2385  would be at the top spring dampening through-hole pair  2384   a . For certain riding conditions, specific reproducibility can be achieved by selecting certain spring dampening through-hole pairs. For example, selecting spring dampening through-holes  2384   c , and using the spring dampening bolts  2387  and spring dampening locking nuts  2388  that are firmly tightened, the pivot axis of the U-channel leaf spring  2385  would be at spring dampening through-hole pairs  2384   c.    
         [0385]    A second leaf spring pivot axis  2327  is formed by the slot  2312  cut along the leaf spring fork arm  2316 . The leaf spring fork arm  2316  will be called the leaf spring fork arm mount  2316 . The spring dampening bolts  2321  are inserted into the spring dampening through-holes  2314   d  on both sides of the leaf spring fork arm mount  2316 . The spring dampening bolts  2321  are then fastened to spring dampening locking nuts  2388  on the opposite side. The spring dampening bolts  2321  are then fastened to a spring dampening locking nut  2323  on the opposite side. If spring dampening bolts  2321  and the spring dampening locking nuts  2323  on the opposite side are fastened tightly, there is no movement. However, if spring dampening bolts  2321  and the spring dampening locking nuts  2323  are fastened together loosely, the space that separates them will determine the leaf spring fork arm mount  2316  maximum excursions. As shown in  FIG. 23C  there is no spring action because the spring dampening bolts  2321  and the spring dampening locking nuts  2323  are in the spring dampening through-holes  2314   d  and any motion is dampened or stopped. Consequently, by selecting the lower spring dampening through-hole pair positions  2384   c ,  2384   b  or  2384   a , will provide maximum controlled leaf spring fork arm mount  2316  excursions. The most spring action that can be achieved by leaf spring fork arm mount  2316  is to use no spring dampening bolts  2321  and no spring dampening locking nuts  2323 . The leaf spring fork arm mount  2316  will pivot about the dashed line pivot axis  2327 . 
         [0386]      FIG. 23D  is a forward off-axis view of the formed fork hanger  2380  and hanger yoke  2370 , which make up the formed fork hanger assembly  2390 . Three leaf spring pivot points are shown that represent the motion of the three leaf springs: U-channel leaf spring  2385  with pivot axis  2325 , formed curved leaf spring  2315  with pivot axis  2326 , and the leaf spring fork arm mount  2316  with pivot axis  2327 . This dampening motion produces a smooth ride. The U-channel leaf spring  2385  pivots about the pivot axis  2325 . The leaf spring fork arm mount  2316  pivots about the pivot axis  2327 . By referencing both  FIG. 23B  and  FIG. 23D , all fastening components are shown: bolts  2387 , spring dampening locking nuts  2388 , spring dampening bolts  2321  and spring dampening locking nuts  2323 . The U-channel leaf spring  2385  and the leaf spring fork arm mount  2316  are shown in the lock down position, with the bolts  2387 , spring dampening locking nuts  2388 , spring dampening bolts  2321  and spring dampening locking nuts  2323  are all tight. The leaf spring  2315  about pivot axis  2326  is not controlled and will act as a shock absorber based on the thickness and type of material used to make the formed fork hanger  2380 . 
         [0387]      FIG. 23E  is a fork arm  2360  with an axel through-hole  2371 . The fork arm  2360  has a fork arm slot  2366  that will slide onto the leaf spring fork arm mount  2316 , as shown in  FIG. 23D . The countersunk through-holes  2365  are of uniform separation and will align with the fork arm through-holes  2319  in the leaf spring fork arm mount  2316 . These countersunk through-holes  2365  are on the top surface  2364  and are the same countersunk through-holes  2365  on the bottom surface  2369 . They share the same through-hole axis. 
         [0388]      FIG. 23F  shows a rear off-axis expanded view of all components used to make up the shock-absorbing reconfigurable fork-truck assembly  2300 . A simpler formed fork truck  2311  is used in this drawing. The formed fork truck  2311  is simpler as it has only one active shock absorbing leaf spring  2315 , which pivots about the dashed line pivot axis  2326  (not shown, see  FIG. 23D ). The U-channel leaf spring  2385  is not used. The baseplate  2350  has a countersunk kingpin through-hole  2334  through which the kingpin  2330  passes and exits the kingpin bulkhead  2354  through the through-hole  2336  (not shown). The slot  2378  allows the hanger yoke  2370  with integrated pivot pin  2304  to slide over the formed fork hanger  2311 . The hanger yoke  2370  is positioned to have the yoke kingpin through-hole  2308  concentric with the formed fork hanger kingpin through-hole  2310 . The hanger yoke  2370  is secured to the formed fork hanger  2311  with bolts  2374  that pass through through-holes  2376  and through through-holes  2386  and are tightened with locking nuts  2372 . The pivot pin resilient cup  2302  is inserted into the resilient cup recess hole  2358  located in the pivot pin bulkhead  2352 . The kingpin threaded end  2332  passes through the top-bushing washer  2338 , top-bushing  2340 , hanger yoke through-hole  2308 , formed fork hanger through-hole  2310 , bottom-bushing  2342 , bottom-bushing washer  2344 , and locked and tightened into place using the locking nut  2346  that is threaded onto the kingpin threaded end  2332 . The fork arms  2360  slide onto the leaf spring fork arm mount  2316  and are bolted in place using short bolts  2362  that pass through countersunk through-holes  2365 , through-holes  2319  and secured in place with locking nuts  2363 . There is a thicker part of the fork arm  2360  that requires a long bolt  2361 . Once both fork arms  2360  are secure, the wheel axel assembly  1700  with wheel  1701  is mounted through fork arm axel through-hole  2371  and tightened in place with washer  2219  and locking nut  2220 . 
         [0389]      FIG. 23G  is an isometric view of a fork arm  2360  configuration that has the leaf spring fork arm mount  2316  slid into the fork arm slot  2366 . The fasteners  2362  pass through the bottom surface  2369  countersunk through-holes  2365 , through the through-holes  2319  of the leaf spring fork arm mount  2316 , as seen in  FIG. 23F . The next set of countersunk through-holes  2365  of the top  2364  of the fork arm  2360  are securely fastened with the locking nuts  2363 . The orientation of the fork arm  2360  in this configuration is flipped from its normal position as defined in  FIG. 23E , which is a slightly lower wheel position. 
         [0390]      FIG. 23H  is a view of a specific fork arm  2360  configuration to illustrate the use of the spacer  2367 . The fork arm  2360  is mounted underneath the leaf spring fork arm mount  2316 . The bottom surface  2369  is mounted to the underside of the leaf spring fork arm mount  2316  to achieve an elevated riding position. To prevent an unstable ride a spacer  2367  is inserted into the fork arm slot  2366 . Normally the leaf spring fork arm mount  2316  slides into the fork arm slot  2366 . The spacer  2367  has through-holes  2368  that are properly spaced to accommodate securing the components with the longer bolts  2361  and the locking nuts  2363  (not shown) for similar fastening procedure. This configuration gives the rider the highest distance above the riding surface. 
         [0391]      FIG. 23I  is a side view of another configuration that raises the wheel closer to the skateboard  1798  (not shown) and creates a more stable ride. The fork arm  2360  slides onto the leaf spring fork arm mount  2316  using the fork arm slot  2366 . The fork arm  2360  is oriented with the top surface  2364  facing in the upward direction and considered the normal orientation as defined in  FIG. 23E . 
         [0392]      FIG. 23J  is the side view of a configuration showing the fork arm  2360  mounted on top of the leaf spring fork arm mount  2316  with the spacer  2367  inserted into the fork arm slot  2366  as explained in  FIG. 23H . The bottom surface  2369  of the fork arm  2360  is in contact with the top of the leaf spring fork arm mount  2316 . This configuration gives the rider the closest ride with respect to the ground and the most stable of riding configurations. 
         [0393]      FIG. 23K  is a side view of the assembled shock-absorbing reconfigurable formed fork-truck assembly  2300  with the wheel axel assembly  1700  and the wheel  1701 . 
         [0394]      FIG. 24A  is an elevated off-axis view of a formed fork hanger  2480  with multiple integrated leaf springs and an integrated axel through-hole  2418 . In  FIG. 23F  the formed hanger fork  2311  and the formed hanger fork  2380  in  FIG. 23G , required a fork-arm  2360  in  FIG. 23  E to mount the wheel assembly  1700  and wheel  1701 . The axel through-hole  2418  is incorporated into the vertical flat  2460  of the leaf spring fork arm mount  2416 . The vertical flat  2460  and the axel through-hole  2418  are formed by the fork arm bend transition  2466 , which is a 90° transition from the leaf spring fork arm mount  2416 . The U-channel leaf spring  2385  pivots about pivot axis  2325 , the formed curved leaf spring  2315  pivots about pivot axis  2326 , and leaf spring fork arm mount  2416 , formerly  2316 , pivots about pivot axis  2327 . The formed fork hanger  2480  is identical to the formed fork hanger  2380  in function including the use of the parallel rows of spring dampening through-holes  2384   a ,  2384   b ,  2384   c ,  2384   d  and  2384   e , which are control points that constrain the movement of the U-channel leaf spring  2385 , the parallel rows of spring dampening through-holes  2314   a ,  2314   b ,  2314   c , and  2314   d  are control points that constrain the movement of the leaf spring fork arm mount  2416 . 
         [0395]      FIG. 24B  is a top view of the formed fork hanger  2480  with multiple integrated leaf springs and an axel through-hole  2418 . The axel through-hole  2418  is incorporated into the leaf spring fork arm mount  2416  at the vertical flat  2460  that is made by bending the leaf spring fork arm mount  2416  at fork arm bend transition  2466  with a  900  twist. The U-channel leaf spring  2385  pivots about pivot axis  2325 , the formed curved leaf spring  2315  pivots about pivot axis  2326 , and the leaf spring fork arm mount  2416  pivots about pivot axis  2327 . The formed fork hanger  2480  is identical to the formed fork hanger  2380  in function including the use of the parallel rows of spring dampening through-holes  2384   a ,  2384   b ,  2384   c ,  2384   d , and  2384   e , which are control points that constrain the movement of the U-channel leaf spring  2385  and the parallel rows of spring dampening through-holes  2314   a ,  2314   b ,  2314   c , and  2314   d , which are control points that constrain the movement of the leaf spring fork arm mount  2416 . 
         [0396]      FIG. 24C  is an isometric view of an assembled shock absorbing formed truck assembly  2400  with a partially assembled wheel axel assembly  1700  and a wheel  1701 . The shock absorbing formed truck assembly  2400  uses the formed fork hanger  2480  with axel through-hole  2418  and the hanger yoke  2370  with the same mounting hardware used on the shock-absorbing reconfigurable fork-truck assembly  2300  used in  FIG. 23F . Wider washers  2461  are used to properly space the wheel axel assembly  1700  and wheel  1701 . Also a wide washer  2461  is used to adequately hold the thinner vertical flat  2460  where the axel through-hole  2418  holds the axel  1714  with the locking nut  2220  securely tightened on the threaded end  1710  of axel  1714 . 
         [0397]      FIG. 24D  is a side view of the completed shock absorbing formed truck assembly  2400  with the formed fork hanger  2480  with axel through-hole  2418  and the hanger yoke  2370  with the same mounting hardware used on the shock-absorbing reconfigurable fork-truck assembly  2300  used in  FIG. 23F . The side view shows the attached wheel axel assembly  1700  and wheel  1701 .
