TECHNICAL FIELD

The present disclosure relates to a bicycle and associated components providing configurations that comfortably accommodate riders of different sizes. In specific non-limiting examples, the present disclosure relates to a bicycle for children that is usable to train the child to ride a bike as well as grow with the child as the child grows.

BACKGROUND

Riders of bicycles come in all different shapes and sizes. There is not a one-size-fits-all answer to accommodate riders of different sizes. Typically, bicycles are designed for riders of a specific size. Bicycle components such as the seat and the handlebars may be raised or lowered to help try and accommodate for riders of different sizes. This may work in instances where different riders are of a similar size or short-term instances where riders of different sizes are not using the same bicycle for years at a time. If the size between two riders varies greatly, typical bicycle configurations may be impractical for the rider or uncomfortable at the very least. A poor fitting bicycle may also feel less stable for the rider. For instance, a center of gravity of the rider is thrown off by a comprised positioning of a rider that tries to compensate for the poor fitting bicycle.

An example where size variance between bicycle riders is great is that where riders are younger children. From an early age, children grow rapidly. Consider an age range of 2 years old to 10 years old. As a single child grows, parents will have to buy multiple different bikes to accommodate for the child's growth, for example, buying a balance bike and then multiple standard pedal bicycles of various sizes. This is not only very costly but also requires management and maintenance of multiple bikes that parents will likely have to get rid of a few years later. Hybrid balance/pedal bikes exist to enable a young child rider to learn and grow with a bicycle. However, parents will still need to buy a new bicycle after several years due to limits in size and function. Larger-sized riders (e.g., older children) may have a lot of trouble with the size of such bikes, for example, where various components may not be designed to adjust in unison with a base of a bicycle. Additionally, such hybrid bikes are not as easily convertible on the fly, for example, when riders of different sizes are using the same bicycle.

Complicating matters, children typically still need training wheels to learn how to pedal a bicycle. As the child learns to ride faster with training wheels, parents may have trouble managing the speed of the bicycle without intervention. Trainers may attach a stick, pole, etc. to the back of the bicycle to be able to grab onto and slow the bicycle down. However, such rudimentary solutions may be limited to a single size and not integrate well with a bicycle (e.g., tie-in with brakes or gears). As training wheels are temporary, they have to be easily attachable/detachable. The same can be said for any traditional mechanism that a trainer may attach for speed control.

SUMMARY

Examples of the present disclosure relate to an adaptable bicycle that is configured to easily and efficiently adapt for riders of different sizes while providing both balance bike and pedal bike functionality. An exemplary bicycle is configured to enable utility adjustments to a front assembly, among other adjustable components, which creates a setup that comfortably accommodates either smaller riders or larger-sized riders. The bicycle of the present disclosure enables adjustment of exemplary components with minimal effort, which allows the bicycle to be re-configured anywhere and at any time with no tools needed. In one example, an exemplary bicycle is a children's bicycle that is designed and developed to grow with a child. An exemplary children's bicycle can be used for training younger children to ride a bicycle (with training wheels) and still be used as the child's primary bicycle as the child grows older and larger in size. For ease of understanding, the present disclosure references a children's bicycle or kids bike. However, it is to be understood that exemplary bicycle configurations and individual components described herein may be implemented individually as well as in bicycle designs of any size. Further disclosed is an exemplary training wheel device that may be attached to an exemplary bicycle to assist with training a young child to ride a bike.

DETAILED DESCRIPTION

Examples of the present disclosure relate to a bicycle that is configured to easily and efficiently convert to accommodate riders of different sizes while providing both balance bike and pedal bike functionality. The bicycle of the present disclosure enables adjustment of exemplary components with minimal effort, which allows the bicycle to be re-configured anywhere and at any time with no tools needed. Further disclosed is an exemplary training wheel device that may be attached to an exemplary bicycle to assist with training a young child to ride a bike. In further examples, the training wheel device is further adaptable to be configured to work with other types of wheeled transportation devices (e.g., a stroller or wheeled car seat), to enable geared and/or brake control for other types of wheeled transportation devices.

In one example, an exemplary bicycle is a children's bicycle that is designed and developed to grow with a child. An exemplary children's bicycle can be used for training younger children to ride a bicycle (with training wheels) and still be used as the child's primary bicycle as the child grows older and larger in size. For ease of understanding, the present disclosure references a children's bicycle or kids bike. However, it is to be understood that exemplary bicycle configurations and individual components described herein may be implemented individually as well as in bicycle designs of any size.

An exemplary children's bicycle is usable to train a small child (e.g., 2-3 years old) to ride a bicycle with training wheels and is further convertible to accommodate a growing size of a child. For instance, depending on the size of the child, an exemplary children's bicycle may grow to comfortably accommodate riders between 6 and 10 years old. In other instances, a larger version of an exemplary bicycle may be manufactured that is targeted for adolescents or adults. An exemplary bicycle is configured to enable utility adjustments to a front assembly, among other components, that comprises one or more components such as a modified front wheel fork, a modified head tube, a modified quick-release locking component and a modified bicycle stem. Such modified components are adaptable to enable a bicycle to change configuration through rotational and/or length adjustments, thereby enabling an exemplary bicycle to be easily adapted to riders of different sizes. As such, an adaptable bicycle of the present disclosure creates a setup that comfortably accommodates smaller riders or larger-sized riders. In examples herein, a front assembly of a bicycle may be rotatable and locked in 180-degree positions to maximize distal spacing and comfort for riders of different sizes without comprising stability and performance of the bicycle. For instance, a front assembly locking component (e.g., quick release bolt, switch, lever) may be engaged to lock the front assembly in a desired position, whether that position of the front assembly may be forward-facing (traditional) or backwards-facing (non-traditional). Other exemplary components are described herein to maximize comfort and ride-ability, where such components comprise but are not limited to: a unique v-shaped configuration of the down tube and the seat tube, an adjustable handlebar slot, handlebar locking component, an adjustable front wheel fork, an adjustable head tube, an adjustable seat post, a curved and elongated top tube and adjustable pedals (e.g., foldable pedals and/or lockable pedals), among other examples.

Among other components, an exemplary bicycle comprises: a front wheel, a rear wheel, handlebars, an adjustable handlebar slot, a locking mechanism to enable handlebar adjustment through the adjustable handlebar slot, a head tube, an adapted bicycle stem, a down tube, a front wheel fork (adjustable), a front assembly locking component configured to enable locking of a front assembly in 180-degree positioning, a down tube, a seat tube, a seat stem, a locking component configured to enable adjustment of a seat stem, a saddle, a pedal assembly (configured to provide a pair of foldable pedals and/or locking component to lock a pair of pedals in a fixed position), a front chain ring, a rear chain ring, a locking component configured for connection of attachments (e.g., an exemplary training wheel device), a bicycle chain, a brake assembly; and a gear assembly, among other examples. In alternative examples, an exemplary bicycle may comprise a one or more seat stays, gears or other traditional bicycle components as known to one skilled in the field of art. In addition to providing some new components and functionality, not seen with traditional bicycles, examples described herein provide a unique frame construction that supports stability and comfort for riders of different sizes.

An exemplary front assembly of the adapted bicycle is customized to enable the functionality described herein where riders of different sizes can easily adjust the size of the bicycle. In non-limiting examples, the front assembly comprises a front wheel fork and an adapted head tube that is attached to the front wheel fork. The head tube described herein in adapted to be reversed from a traditional head tube configuration, wherein the extendable portion of the head tube housing the bicycle stem, headset, etc., is at a bottom portion of the head tube (as opposed to a top portion of a head tube that is the case in traditional configurations). In some further examples, the front assembly may further comprise an adapted bicycle stem configuration, that is modified from a traditional bicycle stem configuration, where the front wheel fork may be connected to the reversed head tube via the modified bicycle stem that is connected with both components. This is enabled by an exemplary head tube being flipped or reversed, where the bicycle stem may be flipped or reversed as compared with traditional bicycle head tube/stem configurations. In such examples, the front wheel fork is connected to the bottom of the reversed head tube, which is traditionally a top portion of a traditionally-used head tube that normally has a bicycle stem connected with the handlebars. The modified configuration of the present disclosure enables the front wheel fork to be extendable, thereby providing distal variance so riders of different sizes can utilize the bicycle comfortably. An exemplary bicycle stem may be slidably adjusted to vary the size of the bicycle stem and/or front wheel fork when a quick-release locking component of the front assembly is disengaged.

An adapted head tube of the front assembly may be connected with a front wheel fork and/or modified bicycle stem in different versions the bicycle of the present disclosure. The head tube comprises a headset, housed within the head tube, enabling rotation of the front assembly and a quick-release locking component that is utilized to lock rotation of a front assembly of an exemplary bicycle. The headset, when in a freely-moving configuration, enables rotation of the front assembly in a first position, where the front wheel fork is forward-facing, and a second position, where the front wheel fork is backwards-facing. In some alternative configurations, the quick-release locking component may be modified to be attached to the front wheel fork and/or bicycle stem. This may require modified sizing, threading and interfacing of components such as the bicycle stem and/or head tube to enable varying positional placement of the quick-release locking component.

In any example, the quick-release locking component is engageable for locking rotation of the front assembly. The quick-release locking component when engaged, locks the front assembly in one of the first position and the second position thereby preventing rotation of the front assembly to return to the other of the first position and the second position. The quick-release locking component, when disengaged, is configured to enable rotation of the front assembly, via the headset, between the first position and the second position. It should be recognized that the front assembly of the bicycle, when the quick-release locking component is engaged, is configured to allow for some rotational movement and flexibility so that a user can comfortable steer and maneuver the front assembly of the bicycle for riding purposes. However, full 180-degree rotation (or greater) is restricted when the quick-release locking component is engaged. To enable such functionality, the quick-release locking component further comprises a locking engagement member that extends through a portion of an inside of the head tube and contacts a tension component affixed inside the head tube. When the quick-release locking component is engaged, the locking engagement member interfaces with the tension component to restrict motion of the headset preventing 180-degree rotation of the front assembly. For instance, the locking engagement member compresses the tension component to applying pressure on the headset so rotational motion is limited. When the quick-release locking component is disengaged, the tension component is decompressed within the head tube enabling full functionality of the headset to achieve 180-degree rotation of the front assembly. Use of a tension component (e.g., a spring configuration) enable some flex in the front assembly to provide enough rotational ability to steer an exemplary bicycle.

In combination with the adapted front assembly, the bicycle (or bicycle frame) of the present disclosure is further configured with an adapted handlebar configuration that accommodates riders of various sizes. For example, an adjustable handlebar slot is connected with the head tube and a pair of handlebars, wherein the adjustable handlebar slot provides a slot that enables the pair of handlebars to be slidably adjusted in a forward direction or a backward direction. This is different than traditional bicycle stem/handlebar configurations, where a bicycle stem is connected with a top portion of a head tube that enables handlebars to be adjusted vertically (e.g., up or down). An adapted bicycle frame further comprises a handlebar locking component (e.g., quick-release locking component) that is attached to the adjustable handlebar slot. The handlebar locking component that is engageable to lock the pair of handlebars in a position within the slot. The pair of handlebars are slidably adjustable in the forward direction or the backward directions when the handlebar locking component is disengaged. This is especially useful when the front assembly of the adapted bicycle is rotated to be locked in different positions.

Moreover, a pedal assembly may be tailored to accommodate riders of different sizes as well as enable the adaptable bicycle to be easily transformed between a balance bicycle and a pedal bicycle. For example, the pedal assembly may comprise a pair of pedals and a modified crank that comprises a locking component to lock the pair of pedals in a fixed position. This enables riders to utilize the pedals as footrests in a balance bike configuration. In one example, a modified crank may be configured to engage/disengage a locking component of the crank through a twisting action that enables locking pins (internally housed in the crank component) to engage/disengage with customized locking slots (also internally housed in the crank component). In another example, locking pins may be engaged/disengaged with locking slots through a pressable locking component or quick-release locking component attached the pedal assembly (e.g., on an exposed end of a crank).

In further examples, the pair of pedals of the pedal assembly are foldable (e.g., pair of foldable pedals), where the pair of pedals can be adjusted to accommodate for either a balance bike configuration or a pedal bike configuration. For instance, a pair of foldable pedals may be adjustable in either: a first pedal position having the pair of foldable pedals folded in an upright position for balance bike purposes or a second pedal position having the pair of foldable pedals engaged in a horizontal position to enable usage of the pair of foldable pedals for pedaling purposes. Such utility may be enabled through connected of one of more additional components to the pedal assembly such as hinge, push-pin folding mechanism or the like as known to one skilled in the field of art. In non-limiting examples, the pair of pedals may be made of a plastic, alloy or composite material that are sturdy, rigid and also lightweight to enable child riders to easily manipulate the pedal positions.

A bicycle frame of an exemplary bicycle further comprises an adapted base assembly that comprises a down tube that is attached to the head tube, and a seat tube that is attached to the down tube. In the adapted base assembly, the down tube and seat tube are engineered to align in a configuration where the down tube and the seat tube are each curved in opposition away from each other. This maximizes distal spacing for a rider when other components of the adapted bicycle are adjusted to help maximize comfort and stability of the bicycle. The base assembly further comprises a top tube attached to the down tube and seat tube, wherein the top tube is curved and extends outwardly from the down tube towards the rear of the bicycle frame. A portion of the top tube may extend outwardly, at an angle, from the seat tube. In some examples, the top tube may extend outwardly from a middle portion of the down tube through a middle portion of the seat tube. The portion of the top tube, extending outwardly from the seat tube, may comprise a bracket assembly for attachment of an accessory device to the bicycle frame. The accessory device may be an attachable/detachable training wheel device as described herein. This engineered configuration enables the attachable/detachable training wheel device to be comfortably connected with the bicycle frame without inhibiting a rider of the adapted bicycle.

For smaller versions of an exemplary children's bicycle, an attachable/detachable training wheel device (e.g., accessory device) may be attached to the rear of the bicycle, for example, on a portion of an exemplary top tube (or seat stay). The training wheel device is customized, as compared with traditional training wheel sets, where the training when device is configured to not only control deployment of a set of training wheels but also enable control over a brake assembly and/or a gear assembly that may be affixed to a bicycle. An exemplary children's bicycle is configured to enable a training wheel device to be quickly attached or detached from the bicycle frame. For instance, the training wheel device connects to a back portion of the exemplary top tube (or seat stay) via a bracket assembly and/or locking component (e.g., quick locking bolt). The back portion of the top tube may extend behind the seat tube and a saddle, where a bracket assembly may be mounted on the bicycle frame (and in some instances the training wheel device) above a portion of the top tube where the rear wheel, rear chain wheel, etc., may be attached. The training wheel device combines a set of deployable training wheels, a guide member and a control device (which may also be a handle mechanism). The training wheel device enables quick attachment/detachment of a set of training wheels to the bicycle without requiring tools. The exemplary training wheel device enables a trainer to control deployment training wheels as well as retraction of the training wheels in a fast and efficient manner. The guide member is usable for a trainer (e.g., parent) to control deployment of the training wheels as well as speed and/or braking control while a child is learning to ride a bicycle. The training wheel device may comprise a control portion that comprises a control device for deployment/retraction of the training wheels.

An exemplary control device (or multiple separate control components) may be configured to interface with other bicycle utilities to control functionality, for example, including but not limited to brake control and gear control. For instance, an exemplary bicycle may be configured to have a gear assembly comprising 2 or more gears. The training wheel device may be configured to connect with the gear assembly so that a control device, of the training wheel device, can be used to switch the gears on the bicycle. This is extremely useful in situations where an adult is guiding a child rider and teaching them how ride a pedal version of the bicycle. The person controlling the training wheel device can help keep the child-rider upright through the training wheel device and also control the speed the bicycle through switching of the gears. For instance, a first gear may be a normal pedaling gear, where if the child gains speed and is pulling the adult too fast, the adult, through the training wheel device, can switch the gears of the bicycle, which automatically slows the bicycle down. The adult, through the training wheel device, can quickly and easily switch back to another gear (e.g., back to the first gear), through the training wheel device, when the speed of the bicycle is comfortable for the adult. The training wheel device may be manually connected to the bicycle, as disclosed herein, where gear lines are configured to be adaptable so that a user can switch the gear lines between the training wheel device and the bicycle (e.g., when the training wheel device is not attached). In further examples, the training wheel device may be configured to connect with a brake line (e.g., a rear brake for the bicycle). A user, when the training wheel device is connected, is able to connect the brake line to some versions of the training wheel device to enable brake control of the bicycle through the training wheel device. An exemplary bicycle may further be configured with brake and/or gear line hardware guide components that guide a connection of a brake or gear line to the bicycle and/or training wheel device. Attachment and detachment of a gear assembly and/or brake assembly, as configured on bicycle, to enable attachment to another device (e.g., the training wheel attachment device) is known to one skilled in the field of art. An exemplary bicycle disclosed herein is configured with components to facilitate easier connection of such components.

As referenced above, an exemplary training wheel device quick is configured to enable adjustment of size and/or positioning of a guide member portion of the training wheel device. In one example, the guide member of the training wheel device is telescoping, where a trainer is configured to be able to quickly adjust a size of the guide member and lock the guide member (e.g., through locking joints/telescoping locking joints) in a comfortable position for training control of the bicycle. The training wheel device may further be comprised of a material that has some flex, where the guide member is rigid but still flexible enough that a user can apply pressure to assist with slowing down a rider of the bicycle. Such materials are known to one skilled in the field of art. In some instances, the training wheel device may comprise additional support components that help stabilize the structure of the guide member and prevent against bending or breaking. Such components include brackets, hinges or the like that may be affixed to the training wheel device at various positions. One skilled in the field of art should understand that positional placement of such support devices may vary to be placed anywhere on the training wheel device as determined through stress testing and product development.

FIG. 1Aillustrates a side view of an exemplary bicycle100and attachable components, with which aspects of the present disclosure may be practiced. Bicycle100may be manufactured to comprise any of the components described herein. It is to be understood that not every component described is required for an exemplary model of bicycle100. In alternative examples, different models of bicycle100can be manufactured, where various different models may vary the combination of components described herein. Additionally, it is to be understood that the size of described components of bicycle100may vary based on a model of the bicycle100that is being produced. For example, the size of component such as the wheels, the handlebars, the seat, the front wheel forks, tubes, etc., may be considerably smaller for a bicycle model that is designed to function for young children as compared to a bicycle model that is designed to function for adolescents or adults. Moreover, it is to be understood that the present disclosure builds upon what already known regarding bicycle components, where bicycle components as known to one skilled in the art may be included herewith to extend functionality of bicycle100. Components of an exemplary bicycle frame, including tubular components, may be made from any strong and rigid material including but not limited to: steel, aluminum alloy, titanium carbon fiber and molded plastic, among other examples of materials used to build bicycle frames as known to one skilled in the field of art.FIGS. 1B-1Kfurther illustrate utility of bicycle100through magnified size views that focus on specific portions of bicycle100.FIGS. 1B-1Kmay further comprise additional components of bicycle100that are not initially visible inFIG. 1A. WhileFIGS. 1A-1Killustrate bicycle100in two dimensions, it is to be understood that components illustrated therein are mirrored (on both sides of the bicycle) creating a three-dimensional representation of bicycle100for actual use.

Bicycle100comprise a uniquely configured bicycle frame, which is designed to maximize utility of components of the bicycle100while maintaining stability and comfort for a rider in any adjustable configuration. Primarily, an exemplary bicycle100enables a rider or trainer to adjust the positioning of an exemplary front assembly to vary distal spacing between the rider and the front wheel/handlebars and pedal assembly, among other components. An exemplary bicycle frame comprises a front assembly. The front assembly may comprise but is not limited to: a head tube102; a front wheel fork104(front fork); a front assembly locking component106configured to enable positional adjustment of an exemplary front wheel fork and/or head tube; a front wheel108; an adapted bicycle stem146, a handlebar locking component110; a pair of handlebars112; and an adjustable handlebar slot114that enables horizontal adjustment of the pair of handlebars. An exemplary front assembly provides a configuration that fosters unique interfacing between components to enable quick and efficient adjustment of a size of the bicycle100. The front assembly may be locked in a forward position (traditional bicycle alignment) using an exemplary front assembly locking component, where the head tube, front fork and front wheel of bicycle100are forward-facing. In another example, the front assembly may be locked, using an exemplary front assembly locking component106, in a reverse position, where the head tube, front wheel fork and front wheel are rear-facing. This enables the front wheel fork to be rotated and locked in 180-degree positions (e.g., forward or backwards), which creates different riding configurations for a rider of the bicycle.

An exemplary front assembly comprises a front assembly locking component106that enables the front assembly to be adjusted or toggled between a first position (forward-facing position reflecting a traditional bicycle riding experience) and a second position (a reverse position/backwards-facing riding experience; 180-degree rotation). In previously existing bicycle examples, if the handlebars were rotated leading the head tube, front fork and front wheel to be in a reversed position, operation of a traditional bicycle may be compromised where that bicycle operates in a wobbly and twitchy manner. This makes traditional bicycle configuration ill-equipped for sustained riding while the handlebars are rotated in a reversed position. Another major issue with attempting to ride a traditional bicycle with the handlebars rotated in a reversed position is that the rider is required to physically hold the handlebars in that position. If the rider lets the handlebars go, the handlebars will snap back to the original position, which means that a reversed position of the handlebars is not only temporary but also dangerous. This would be especially troublesome for young riders that are first learning to ride a bike. Through adjustment of the various components as well as the unique design of its machined components, the adaptable bicycle of the present disclosure resolves these issues and enables safe riding where the front assembly is locked in the first position or the second position.

The head tube102is a part of the bicycle frame that connects the front wheel fork104, the pair of handlebars112and associated components (e.g., handlebar locking component110and adjustable handlebar slot114). Size and dimensions of an exemplary head tube102may vary depending on size of the bicycle being manufacturer, for example, a children's bicycle or an adult bicycle. The head tube102may house a bicycle stem146as well as other components such as a front fork steerer tube and headset (e.g., collection of cups, spacers and bearings), as known to one skilled in the field of art. Such components are not illustrated inFIGS. 1A to 1Kas they are known to one skilled in the field of art. A headset provides a rotatable interface between the head tube102and the front wheel fork104. This allows the front assembly of bicycle100to rotate freely in at least 180-degree positions (forward-facing and rear-facing). Exemplary headsets may be threaded or unthreaded. A visual example of a headset210is shown inFIG. 2A, where the headset210is affixed to a bottom portion of the head tube102(and partially housed in the head tube102) as well as proximate to the front assembly locking component106.

As referenced above, an exemplary head tube102is reversed upside down, as compared with a traditional head tube mechanism. This may further allow adjustment of the front wheel fork104, including extension of blades of the front wheel fork104that may be engineered to be extensible. In this reversed/upside down configuration, an exemplary bicycle stem146(also shown inFIGS. 1B and 1C) of the head tube102(or an extendible tube within the head tube) interfaces directly with the front wheel fork104to enable adjustment of the front wheel fork104for optimized spacing and stability. This reversed configuration enables height adjustment as well as rotary adjustment of the front wheel fork104by which the distance between a front wheel and a rear wheel may be increased. In one instance of the reversed (upside-down) configuration, a stem component146(e.g., bicycle stem, also shown inFIGS. 1B-1C) may be connected with the head tube102and the front wheel fork104to enable height, angle and/or and rotational adjustment of the head tube102and/or front wheel fork104. For example, a bicycle stem146may interface with the front assembly locking component106(e.g., quick-release locking component), where when the front assembly locking component106is disengaged, any of the length, angle and/or rotational positioning of the front assembly may be manipulated. When the front assembly locking component106is engaged (e.g., locked), the front assembly may be restricted from adjusting in length (height), angle or rotational positioning.

An exemplary head tube102further comprises the front assembly locking component106. As referenced above, the front locking component106is configured to engage/disengage a locking component to enable adjustment of one or more components of the front assembly of bicycle100. Engaging the front assembly locking component106enables the front wheel fork104to be locked in a first position (forward-facing position) or a second position (rear-facing position/backwards-facing position), creating 180-degree positional variance. This configuration allows for greater distance between front and rear wheels of bicycle100, thus becoming a bigger bike for a larger rider such as an older child. Furthermore, bicycle100enables adjustment of an exemplary front wheel fork104(and reversed bicycle stem) to maximize spacing for riders of different size as alternative to traditional bicycles where a rider may adjust the handlebars that are connected to a traditionally upward facing bicycle stem and still not comfortably operate a bicycle. In one non-limiting example, the front assembly locking component106may be affixed to a bottom portion of the head tube102(in the reversed configuration) closest to the front wheel fork104and/or bicycle stem146. However, in other examples, positioning of the front assembly locking component106may vary along the head tube102or another component of the exemplary bicycle100. For instance, the front assembly locking component106may be affixed to the front wheel fork104, the bicycle stem146or a top portion of the head tube102. This may require modified sizing, threading and interfacing of components such as the bicycle stem and/or head tube, where such engineering is known to one skilled in the field of art, thereby enabling varying positional placement of the front assembly locking component106.

An exemplary front assembly locking component106may be a quick-release mechanism (e.g., quick-release locking component), which may be in any form including but not limited to: a bolt, a bracket, a skewer, a rod, a lever, a handle, a push button/spindle a pin and a switch, among other examples. Exemplary components of a quick-release mechanism and arrangement of such components are known to one skilled in the field of art. For instance, an exemplary quick-release mechanism may comprise a plurality of components including but not limited to any combination of: a lever/cam/skewer assembly, springs (e.g., conical springs), a hub axle, a retaining ring, ball bearings, locking pins, a bracket and an adjusting nut, as known to one skilled in the field of art. Inclusion of components such as springs and an axle may assure that a fair amount of direct pressure is applied to a quick-release lever/handle to enable engagement/disengagement, enabling most adjusts to be purposeful rather than involuntary. In some instances, a push button or lever of the quick-release mechanism may be housed by a protective cap or protective barrier (e.g., plastic cover or other similar material, nautical handle), which has to circumvented, removed, opened, etc., to actually make contact with the push button/lever of the quick-release mechanism. This may further prevent involuntary contact from being made with the quick-release mechanism.

A majority of the components of the quick-release locking mechanism are housed within the head tube102and/or bicycle stem146with the exception of a portion of an exemplary locking engagement member (e.g., lever, object connected with the quick-release component) that is used for engagement/disengagement of the quick-release mechanism of the front assembly locking component106. An exemplary quick-release mechanism may work by clamping against components of an exemplary headset and/or bicycle stem to restrict movement of such components. In an example where the quick-release mechanism is engaged, a skewer or rod of a quick-release assembly may contact a component such as a bearing, a pin, tension component (e.g., spring) to restrict movement of the headset component and/or bicycle stem component, locking it in a set position. An order of contact may vary depending on whether models of bicycle100comprise an exemplary bicycle stem or not. As an example, when the quick-release locking mechanism is engaged, the rod or axle may slidably engage with one or more components of the headset (or an added tension component) to restrict rotational movement of the headset (e.g., prevent the front assembly from being rotated in 180-degrees, 360 degrees, etc.). In further examples, an exemplary headset or bicycle stem may be modified to connect with a rod or axle of the quick-release locking mechanism. In another example, the quick-release locking mechanism, when engaged, locks a bolt in place that restricts rotation of an exemplary headset. For instance, a locking of the quick-release locking mechanism pushes a bolt upwards to restrict movement of the headset and/or a tension component. When the quick-release locking mechanism is disengaged, position of the bolt may shift to enable rotation of the headset. For instance, the bolt is pulled downwards when the quick release locking mechanism is disengaged.

Above what is traditionally known about quick-release locking components, the locking component utilized herein is specifically configured to engage/disengage components of a front assembly to control rotation of the front assembly. The quick-release locking component when engaged, locks the front assembly in one of the first position and the second position thereby preventing rotation of the front assembly to return to the other of the first position and the second position. The quick-release locking component, when disengaged, is configured to enable rotation of the front assembly, via the headset, between the first position and the second position. It should be recognized that the front assembly of the bicycle, when the quick-release locking component is engaged, is configured to allow for some rotational movement and flexibility so that a user can comfortable steer and maneuver the front assembly of the bicycle for riding purposes. However, full 180-degree rotation (or greater) is restricted when the quick-release locking component is engaged. To enable such functionality, the quick-release locking component further comprises a locking engagement member that extends through a portion of an inside of the head tube and contacts a tension component affixed inside the head tube. When the quick-release locking component is engaged, the locking engagement member interfaces with the tension component to restrict motion of the headset preventing 180-degree rotation of the front assembly. For instance, the locking engagement member compresses the tension component to applying pressure on the headset so rotational motion is limited. When the quick-release locking component is disengaged, the tension component is decompressed within the head tube enabling full functionality of the headset to achieve 180-degree rotation of the front assembly. Use of a tension component (e.g., a spring configuration) enable some flex in the front assembly to provide enough rotational ability to steer an exemplary bicycle.

Continuing description of the front assembly, an exemplary front wheel fork104is attached to the head tube102. In one example, the front wheel fork104may be welded to the bottom portion of the head tube102. An exemplary front wheel fork104may comprise one or more fork tubes, as known to one skilled in the field of art. Exemplary fork tubes may further connect with the head tube102through the front fork steerer tube as known to one skilled in the field of art. In examples, fork tubes may be configured to enable adjustment of the front wheel fork104including but not limited to: vertical adjustment, horizontal adjustment and angle. For instance, exemplary fork tubes may be connected with bicycle stem146, where when the front assembly locking component106is disengaged, components of the front wheel fork104may be adjusted in any of the above identified manners, for example, to account for a size of a rider. In one instance, a headset like design is implemented in tubing of the front wheel fork104(e.g., front fork tube) or the front fork tube is connected with the headset in the head tube102, which may enable vertical and/or horizontal adjustment of blades of the front fork. In alternative examples, the front wheel fork104may comprise one or more individual components (e.g., quick-lock/release components) enabling adjustment of the front wheel fork104or specific portions of the front wheel fork104such as the fork blades.

In any example, the front wheel fork104is constructed out of a material that enables the fork to be stiff and rigid. Exemplary materials for fork construction that can produce a stiff front fork have been referenced in the foregoing description and are known to one skilled in the field of art. A thickness and weight of frame components including the front wheel fork104may vary depending on the size of the bicycle being manufactured without departing from the spirit of the present disclosure. Bicycle100is configured to enable stable and comfortable riding with the front wheel fork104forward-facing as well as backwards-facing. In this way, a configuration of the front fork104is optimized, from that of traditional bicycle, thereby enhancing stability for the rider (in any position) as well as maximize distal spacing for the rider thus increasing comfort and ride-ability of the bicycle. In examples where the front wheel fork104is in a reversed position and a rider is trying to ride, traditional bicycles may be twitchy and wobbly, which makes the rider feel unstable and unsafe. As compared with traditional forks, an exemplary front wheel fork104described herein may manufactured to be thicker (or wider) and heavier, where a traditional fork may be smaller and thinner/skinnier, for example, on a children's bicycle. This utility design may provide comfort and stability for the rider, making the bicycle feel more stable and less twitchy.

In at least one example, an exemplary front wheel fork104is curved, extending outwardly at an angle from the head tube102. For instance, blades of the front wheel fork104may be curved at the top (e.g., at approximately 90 degrees) and attached to the head tube102or reversed bicycle stem146extending from a bottom portion of the head tube102. Moreover, an exemplary curved front fork may also be elongated, as compared with traditional forks on children's bicycles. Elongation of the front wheel fork104is aimed at increasing the rake and reducing trail of the bicycle, thereby providing greater stability in instances when the front fork is reversed.

A front wheel108may be connected with the front wheel fork104. For example, front wheel fork104may comprise a fork-end or set of dropouts that enable connection of the front wheel104to the front wheel fork104. Exemplary components of a wheel of a bicycle are known to one skilled in the field of art as well as mechanisms for connection the front wheel108to the front wheel fork104are known to one skilled in the field of art and may comprise but are not limited to bolt(s), quick-release mechanisms or the like. Size of the front wheel108may vary depending on a model of bicycle100that is being manufactured. For example, tire sizes may range from 12 inches to 26 inches for children's bicycles. However, bicycle100may be configured to work with tires of any size. In at least one example, bicycle100may be manufactured and sold with multiple sets of tires of different sizes, for example, 12-inch tires (front wheel108and rear wheel128) and 16-inch tires to enable the tires to be swapped out so that a child may more comfortably ride bicycle100as the child grows. Additionally, placing the front assembly in the different positions (e.g., first position and second position) may allow for different size wheels to be attached to the bicycle (e.g., as kids grow bigger or larger riders utilize the bicycle).

The front assembly of bicycle100may further comprise handlebar components including a handlebar locking component110, a pair of handlebars112and an adjustable handlebar slot114. As the front assembly may be rotated and locked in 180-degree positions, adjustment of the pair of handlebars112is necessary to optimize rider comfort for riders of different sizes. Handlebars provide steering control for a bicycle. Typically, handlebars are adjustable vertically, via raising/lowering a bicycle stem. Exemplary bicycle100differentiates from such configurations by enabling horizontal adjustment of the pair of handlebars112(e.g., forwards and backwards) via a combination of the handlebar locking component110and the adjustable handlebar slot114. This type of adjustment optimizes handlebar positioning, for example, when the front assembly is rotated in 180-degree positions. The pair of handlebars112may any type of handlebar including but not limited to: flat bars, curved bars, riser bars, drop bars, bullhorns, aero bars, cruiser bars, H bars and butterfly bars, among other examples. An exemplary pair of handlebars112may be sized for a model (e.g., for children or adults) of bicycle100that is being manufactured. In examples where an exemplary bicycle100is a children's bicycle that is used for training young children to ride a bike, an exemplary pair of handlebars112may be mid-rise handlebars, which may present handlebar positioning that may provide increase control of bicycle100as well as minimize the strain on the neck of the rider. Other examples of handlebars that may be used include low-rise handlebars (e.g., flat bars), which may be best for aggressive or all-terrain riding. Alternatively, high-rise handlebars (e.g., cruiser bars) may be used as well, though this may limit overall control and maneuverability for an in-experienced rider.

Hand brakes (not shown) may also be connected to the bicycle frame of bicycle100as known to one skilled in the field of art. For example, the hand brakes (e.g., brake levers or pedals) are attached to the pair of handlebars112of the front assembly and one or more brake lines may run across components of the bicycle frame including the front assembly and a base assembly connecting with a brake mechanism on the rear of bicycle100. Exemplary hand brakes may be of any kind as known to one skilled in the field of art including but not limited to rim brakes, disc brakes and drum brakes, among other examples. In alternative examples, bicycle100may be configured to work with coaster brakes as an alternative to handbrakes. Coaster brakes and implementation are known to one skilled in the field of art. In some alternative examples, bicycle100may comprise a hybrid braking system that may combine handbrakes and coaster brakes to further train children how to use both types of brakes. As previously referenced, brake lines may be connected to an attachable/detachable training wheel device that allows a user of the attachable/detachable training wheel device to control brake functionality on behalf of a rider. This is useful in situations such as when a parent is teaching a child to ride a bicycle.

An exemplary handlebar locking component110is used to enable adjustment of the pair of handlebars112. As referenced above, handlebar height is typically adjusted through manipulation of a bicycle stem. The handlebar locking component110(e.g., handlebar locking mechanism) of the present disclosure is a quick release/lock that enables (horizontal) sliding of the handlebars forward or backwards through the adjustable handlebar slot114. Examples of quick-release locking mechanisms have been previously described. When the handlebar locking component110is unlocked, the pair of handlebars112are configured to slide freely through any portion of the adjustable handlebar slot114. In one example, the adjustable handlebar slot114is a single unitary slot, where the pair of handlebars112can be moved into any position within the single unitary slot while the handlebar locking component110is unlocked. A user may unlock the handlebar locking component110, move the pair handlebars112to a desired position within the adjustable handlebar slot114and re-engage the handlebar locking component110to lock the pair of handlebars112in place. That is, the handlebars may be slidably (e.g., forwards and backwards) adjusted through the entirety of the adjustable handlebar slot114. In an alternative example, the adjustable handlebar slot114may comprise a plurality of positional slots, where a user may unlock the handlebar locking component110and horizontally slide the handlebars to a desired positional slot and lock the handlebars in place through re-engagement of the handlebar locking component110.

Bicycle100further comprises a base assembly that is affixed to the front assembly. The base assembly may comprise: a down tube116; a seat tube118; an adjustable seat post162(shown inFIGS. 1E and 1F); a saddle122; and a top tube124. Further connected to the base assembly is a rear wheel128; an attachment locking mechanism132that is connected with the top tube124; and a rear chain assembly138. In some examples, an exemplary training wheel device130may be attached to the rear of the top tube124via the attachment locking mechanism132, for example, to enable assistance for training young children to ride bicycle100. However, the training wheel device130is attachable and detachable from bicycle100, where some models of bicycle100may not require the training wheel device130to be a necessary component. The base assembly may further comprise other known bicycle components, as known to one skilled in the art, comprising but not limited to: a bicycle chain; chain wheels; chain guards; brakes; and bicycle gears, among other bicycle components. For instance, bicycle pedals126bmay be configured to operate with a coaster brake assembly, as known to one skilled in the field of art, which may provide an alternative to requiring hand brakes.

Exemplary tubular components such as the down tube116, seat tube118and top tube124may be constructed out a similar material as described in the foregoing description. An exemplary down tube116connects components of the front assembly of the bicycle frame with other components of the base assembly. The down tube116may be welded to the head tube102of the front assembly. In some examples, the down tube112and the head tube102may be welded as single unit. In one instance, the down tube112and the head tube102are constructed in a manner with each is flush with the other. In alternative instances, the down tube112may protrude forward from the head tube102, for example, holding accessories (e.g., light fixture, small basket).

The down tube116may be welded with other tubular components such as the seat tube118and the top tube124. The down tube116is also directly connected with the seat tube118and the top tube124. The shaping of the down tube116and the seat tube118of the exemplary bicycle100is engineered to maximize spacing and comfort for riders of different sizes through a unique V-shape configuration. To create the V-shape configuration, the down tube116and the seat tube118are curved in opposition of each other, where the down tube118arches/curves away from the seat tube116and the seat tube118arches/curves away from the down tube116. In essence, down tube116and the seat tube118create an arching V-shape for the bicycle frame that is projects upwardly (vertically) from the ground and provides a larger and more stable base for bicycle100as compared with traditional children's bicycles.

The seat tube118is connected to a saddle122(i.e. bicycle seat). The saddle122may be in any shape and any material as known to one skilled in the field of art. As the V-shape configuration comprises an arching seat tube118, a seat stem162(as shown inFIGS. 1E and 1F) for the bicycle saddle122extends at an angle that follows the trajectory of the arched seat tube118. This configuration creates more space for a larger rider (e.g., larger child) to ride more comfortably upon adjustment of the saddle122. The same can be said for a smaller rider, where adjustment of the saddle122may be made to enable more comfortable riding. The seat tube118may further comprise a locking component120that enables locking/unlocking of the seat stem/post for adjustment of positioning of the saddle122. Exemplary locking component120may be a quick-release locking mechanism as described in the foregoing description. The locking component120for the seat stem162may be affixed to the seat tube118or the seat stem162.

Additionally, a front chain wheel/ring126aand a bicycle pedal assembly126bare attached to base assembly, for example, at the bottom of the intersection between the down tube116and seat tube118. Configuration and implementation of an exemplary front chain wheel/ring126awith an exemplary bicycle pedal assembly126bare known to one skilled in the field of art. For example, the front chain wheel/ring126amay comprise but is not limited to: a hub, a crank, and a front derailleur, among other exemplary components. The front chain wheel/ring126ais connected with the bicycle pedal assembly126b, which comprises a set of pedals connected to the crank of the front chain wheel/ring126a. In one example, a limited but sufficient chain cover (not shown) may be attached to the front chain wheel/ring126ato protect the chain ring. In a non-limiting example, a circular chain cover (e.g., plastic or metal) may be attached over the front chain wheel/ring126a, where the chain cover does not extend to the rear dropout of bicycle100as is the case with some other children's bicycles. This is because bicycle100may also be configured for attachment of accessory devices such as the training wheel device130on the rear of the bicycle frame of bicycle100.

Moreover, a pedal assembly126bmay be tailored to accommodate riders of different sizes as well as enable the adaptable bicycle to be easily transformed between a balance bicycle and a pedal bicycle. For example, the pedal assembly126bmay comprise a pair of pedals and a modified crank that comprises a locking component to lock the pair of pedals in a fixed position. This may enable riders to utilize the pedals as footrests in a balance bike configuration. In one example, a modified crank may be configured to engage/disengage a locking component of the crank through a twisting action that enables locking pins (internally housed in the crank component) to engage/disengage with customized locking slots (also internally housed in the crank component). In another example, locking pins may be engaged/disengaged with locking slots through a pressable locking component or quick-release locking component attached the pedal assembly126b(e.g., on an exposed end of a crank).

In further examples, the pair of pedals of the pedal assembly126bare foldable (e.g., pair of foldable pedals), where the pair of pedals can be adjusted to accommodate for either a balance bike configuration or a pedal bike configuration. For instance, a pair of foldable pedals may be adjustable in either: a first pedal position having the pair of foldable pedals folded in an upright position for balance bike purposes or a second pedal position having the pair of folded pedals engaged in a horizontal position to enable usage of the pair of foldable pedals for pedaling purposes. Such utility may be enabled through connected of one of more additional components to the pedal assembly126bsuch as hinge, push-pin folding mechanism or the like as known to one skilled in the field of art. In non-limiting examples, the pair of pedals may be made of a plastic, alloy or composite material that are sturdy, rigid and also lightweight to enable child riders to easily manipulate the pedal positions.

The base assembly further comprises a top tube124that is welded to the down tube116and the seat tube118. An exemplary top tube124may be engineered to curve away from the down tube extending towards the rear of the bicycle. In one example, the top tube124may extend from the middle of down tube116to the center of the rear wheel128of the bicycle100, for example, where dropouts may be mounted. For instance, the top tube124may have a front portion that is between the down tube116and the seat tube118and a back portion that extends behind/past the seat tube118towards the rear of the bicycle. In such a configuration, seat stays of a traditional bicycle are eliminated and no longer needed for support. One benefit to this configuration is that the tensile strength of the top tube124may carry through to the rear portion of the bicycle where accessory devices, such as training wheel device130, may be attached. In alternative instances, a separate seat stay may be attached to the seat tube118extending outwardly towards the rear of the bicycle.

The back portion of the top tube124(or a seat stay) may be engineered to be wider for strength and stability purposes. In some examples, a parent or trainer may be pulling on the back portion of the top tube124where an exemplary training wheel device130may be attached. Engineering and stress testing may determine an appropriate size and tensile strength for the top tube124(or seat stay) and any other components of an exemplary bicycle frame. In one instance, the entirety of the top tube124may comprise a uniform size and thickness. In another instance, the back portion of the top tube124, replacing a traditional seat stay, may be engineered to be wider than the other portion of the top tube124that is connected between the down tube116and the seat tube118. In any case, the back portion of the top tube124(or a seat stay) may be curved to follow the angle and trajectory of a front portion of the top tube124that is between the down tube116and the seat tube118. A shape of the top tube124may vary without departing from the spirit of the present disclosure. In one instance, the back portion of the top tube124(or a seat stay) is oval-shaped and engineered to be thin enough to enable brackets and/or bolt connections to be mounted therethrough.

In other examples, a configuration of a top tube124may vary to enhance stability of the bicycle100. An exemplary seat stay may mimic a back portion of the top tube124, where the seat stay may follow the curved trajectory of the top tube124. In one alternative instance, the top tube124may be welded between the down tube116and the seat tube118in a straight configuration (e.g., perpendicular between the down tube and seat tube). In such an alternative example, a seat stay (not shown) may be welded to the seat tube and extend outwardly from the seat tube towards the rear of the bicycle. In that case, the seat stay may curve away from the seat tube118in a manner that extends towards the rear of the bicycle100(where a rear wheel may be mounted).

The back portion of the top tube124(or the seat stay) may further comprise a bracket assembly132for attachment of an accessory device to the bicycle frame of bicycle100. As referenced in the foregoing, an example of an accessory device is a training wheel device130that is attachable to and detachable from the bicycle frame. The bracket assembly132is used to connect the training wheel device130to the bicycle frame, for example, to the back portion of the top tube124(or the seat stay). Components of an exemplary bracket are known to one skilled in the field of art. An assembly bracket assembly132may comprise but is not limited to: a bracket, a bracket connector (attached to an accessory device) and one or more bolts, clamps, etc., to secure an accessory device to the back portion of the top tube124(or seat stay). An exemplary bracket assembly132is manufactured out of material that has a high tensile strength and is able to withstand a large amount of force being applied to the bracket. Examples of such materials are known to one skilled in the field of art. In operation, a trainer may be controlling operation of bicycle100, to assist a young rider, via the training wheel device130. In one example, the bracket assembly132overlaps a top side of the top tube124(or seat stay) for stability and strength. For instance, the bracket assembly132may overlap 90 percent or more of the top portion of the top tube124(or seat stay). However, an amount of overlap may vary depending on engineering testing without departing from the spirit of the present disclosure.

The bracket assembly132may further comprise one or more mounting slots to enable engagement of the one or more bolts (or other locking mechanisms), which are used to secure an accessory device to the bicycle frame. For example, two mounting bolt slots, one on each end the bracket assembly132, may be included therein. A bracket component, on an accessory device, may interface with a bracket component, on the bicycle frame, enabling a user to secure the accessory device to the bicycle frame using the bolt(s). In an alternative example, one or more apertures may be drilled into the bicycle frame to enable securing of an accessory device to the bicycle frame via the bracket assembly132. In that example, exemplary bolts may pass through the one or more apertures to lock into an opposing side of a bracket of the bracket assembly132. This may assist with transferring some of the stress of a joint between the bicycle frame and the bracket assembly132through the top tube124(or seat stay) which may have greater tensile strength.

Additionally, bicycle100may comprise a rear wheel128that is connected to the back portion of the top tube124(or seat stay). The rear wheel128may be the same wheel size, shape, type, etc. as the front wheel108previously described. For example, tire sizes may range from 12 inches to 26 inches for children's bicycles. Attachment and components used for attaching a wheel to a bicycle, including the front wheel108and the rear wheel128, are known to one skilled in the field of art. As an example, the bicycle frame may be equipped with a quick-release mechanism enabling attachment/detachment of the rear wheel128to a rear chain assembly138. Components of an exemplary rear chain assembly138are known to one skilled in the field of art. For example, the rear chain assembly138may comprise but is not limited to: a hub, a freewheel (cassette), a rear derailleur, among other exemplary components. Bicycle100may further comprise dropouts, affixed to the bicycle frame, to enable connection of the rear wheel128to the bicycle frame. Additionally, bicycle100further comprises a bicycle chain (not shown) that may be attached to the rear chain assembly138and the front chain wheel/ring126a, as known to one skilled in the field of art.

An exemplary bicycle100may further comprise a gear assembly (not shown). A gear assembly and incorporation of a gear assembly into a working bicycle is known to one skilled in the field of art. Above what is known in the field of art, the present disclosure discloses the ability to manipulate the gear assembly so that the gear assembly is connectable with an attachable/detachable training wheel device130.

As referenced in the foregoing description, an exemplary training wheel device130connects to portion of the top tube via the bracket assembly132. The training wheel device130combines a set of deployable training wheels136, a guide member (portions of which are illustrated inFIGS. 1I-1K) and a control device140(or handle mechanism) that is affixed to the guide member. The training wheel device130enables quick attachment/detachment of the set of training wheels136to the bicycle without requiring tools. For instance, the configuration of bicycle100enables a user to attach the training wheel device130to the back portion of top tube124(or seat stay) and just as easily remove it when not in use. Attachment/detachment of the training wheel device130is configured to be easier than requiring a user to attach/remove a set of training wheels to a bicycle. In further examples, the training wheel device130may be attached to other types of transportation devices such as strollers, or wheeled car seat, wagons, etc., to enable similar control to that described with respect to bicycle100.

The guide member is usable for a trainer (e.g., parent) to exert force and/or use features of control device140to control bicycle100while a young child is learning to ride. The exemplary training wheel device130enables a trainer to control deployment of the set of training wheels136as well as retraction of the training wheels136in a fast and efficient manner, through the control device140. The guide member may be an elongated oval shaped tubing (or multiple tubular components) that enables mechanical components to be housed within or attached to the tubular portion(s). In one example, the guide member of the training wheel device130is telescoping, where a trainer is able to quickly adjust a size of the guide member and lock the guide member (e.g., through locking joints/telescoping locking joints) in a comfortable position for training control of the bicycle100. Examples of telescoping functionality of the guide member is illustrated inFIGS. 1I to 1Kand subsequently described in further detail. Moreover, a shape of the training wheel device130curves outward away from the bicycle so that a trainer can comfortable stand behind the bicycle frame and still control bicycle100.

The guide member may comprise a plurality of portions comprising but not limited to: a top portion, a bottom portion and a middle portion (refer to at leastFIG. 1Iand the accompanying description). Tubular components of the guide member may be made out of a sturdy but flexible material, for example various types of metals (e.g., spring steel), composite fiber or plastics as known to one skilled in the field of art. Sizing of the individual portions of the guide member may vary in different models. In one example, the guide member may be manufactured where portions of the guide member, that are further from the distal end (of the top portion), become thinner as guide member reaches a portion (bottom portion) that attaches to the bicycle frame. In another example, the bottom portion of the guide member may be thicker than the top and middle portions of the guide member, for example, to provide a more solid base for attachment of the training wheel device to the bicycle frame. The guide member may further comprise one or more telescoping joints134aand134b, respectively, that enable a trainer to quickly adjust the size of the training wheel device130. As an example, telescoping joints134aand134bmay comprise a locking mechanism that is enable through locking pins, spring clicks or the like in combination with actions such as twisting and locking and pressing of button(s)/lever(s), among other examples.

An exemplary control device140is configured to interface with other bicycle utilities to control functionality including but not limited to: deployment of the set of training wheels136; braking control; and gear control. In non-limiting examples, the control device140may be a depressible control pad (e.g., comprising buttons to control various functionality) or a handle-like mechanical mechanism that enables a user to exert force to raise/lower the set of training wheels136. Control device140may comprise a plurality of control elements (buttons, levers, spring clips) that enables a trainer to control various aspects of the bicycle100. In one instance, control device140may comprise a button-like control for deployment of the set of training wheels136and another button for application of one or more bicycle brakes (e.g., front brake and/or rear brake) where the training wheel device130interfaces with an exemplary brake assembly. A brake assembly is a collection of components configured to for the application of braking as known to one skilled in the field of art. In a further example, an exemplary bicycle may be configured to interface with a gear assembly (e.g., multi-gear stack exchange) to enable control for switching gears of the gear assembly. Components of a gear assembly are known to one skilled in the field of art. Interfacing between the training wheel device130and the gear assembly enables a trainer to control the speed of bicycle100to maintain safety for a child as well as comfort for a parent training the child to ride bicycle100. In one instance, a third control button may be configured to control the gear assembly.

Housed within the guide member portions is spring-enabled assembly that provides control over deployment of the set of training wheels136. A visual example of the spring-enabled assembly is illustrated inFIG. 1J, among other portions of the present disclosure. The spring assembly may comprise one or more springs, that, when engaged, are configured to exert force and deploy the training wheels in a usable position (touching the ground). The spring assembly further comprises an attachment mechanism that connects the spring with a handle/control device140of the guide member. Examples of an attachment mechanism comprise but are not limited to: one or more springs, wires (e.g., metal), spring clips, cable(s), a cable reel and a spring motor assembly, among other examples.

Furthermore, as referenced above, training wheel device130may be connected with a brake assembly or gear assembly of bicycle100. A brake line (or lines) of the brake assembly may be connected with the training wheel device130, for example, with a control component (e.g., button, lever) that enables a trainer to apply the brakes to the bicycle via the control device140. In another instance, a gear line (e.g., to a gear shifting mechanism) may be routed to the training wheel device130, for example, with a control component (e.g., button, lever) that enables a trainer to adjust the gears of the bicycle via the control device140. Once the training device130is removed permanently, brake lines and/or gear lines may be manually re-routed to the front assembly of the bicycle, which may comprise a brake component and/or a gear shifting component attached to the pair of handlebars112. This enables the child to control the brakes and/or gears of the bicycle themselves. Exemplary brake components and gear shifting components are not illustrated inFIGS. 1A-1Kbecause such components, including brake lines and gear lines, are known to one skilled in the field of art. In some examples (not shown), a bicycle frame may be fashioned with defined slots, in the bicycle frame, to guide a user with switching control of a brake assembly and/or a gear assembly between the front of the bicycle100and the training wheel device130.

FIGS. 1B-1Killustrate magnified size views of components of an exemplary bicycle, with which aspects of the present disclosure may be practiced.FIGS. 1B-1Kfurther exemplify components of bicycle100(FIG. 1A) as well as provide views of additional components of exemplary bicycle100.

FIG. 1Bprovides side view145, illustrating a forward-facing position (traditional) of an exemplary front assembly of bicycle100(FIG. 1A). The front assembly locking component106is engageable to lock the front assembly in the forward-facing position shown in side view145.

FIG. 1Cprovides side view150, illustrating a backwards-facing position (reversed; non-traditional) of an exemplary front assembly of bicycle100(FIG. 1A). The front assembly locking component106is engageable to lock the front assembly in the backwards-facing position shown in side view150.

FIG. 1Dprovides side view155, illustrating exemplary handlebar components of bicycle100(FIG. 1A). As referenced in the foregoing description, handlebar components of bicycle100comprise: a handlebar locking component110, a pair of handlebars112and an adjustable handlebar slot114. Side view155illustrates adjustment of the pair of handlebars112. For example, a user may disengage the handlebar locking component110and slide the pair of handlebars (horizontally) through the adjustable handlebar slot114. While the handlebar locking component110is disengaged, a user may slide and position the pair of handlebars112at any point within the adjustable handlebar slot114. For example, a user may lock the front assembly of bicycle100in a backwards-facing position (reversed; non-traditional) and adjust the pair of handlebars112through the adjustable handlebar slot114for improved comfort and stability of the rider. As described in the foregoing description, the adjustable handlebar slot114may be fashioned with slots (pre-fabricated slots) that enable a user to lock the pair of handlebars112in specific set positions within the adjustable handlebar slot114. In additional examples, bicycle100may further comprise components that enable the handlebars to be adjusted in other orientations such as the angle of the handlebars.

FIG. 1Eprovides side view160, illustrating seat stem162, which enables adjustment of a height of the saddle122(bicycle seat). A user may disengage/unlock the locking component120for the seat stem162, where the user can raise or lower the seat stem162when the locking component120is disengaged.
