     BACKGROUND 
     1. Field 
     Embodiments relate to the field of bicycles, and, in particular, to improved designs for versatile electric bicycles. 
     2. Description 
     With the development of new technologies, various types and kinds of electric bicycles are available today that can operate on electric and/or manual power. Many different types of electric bicycles are available and comprise various types of parts, such as motors and batteries, customized for different laws and regulations of each jurisdiction. Most electric bicycles are quite particular and lack compatibility or flexibility. For example, a certain electric bicycle can be restricted to be used in conjunction with certain parts, certain configurations, and/or within certain jurisdictions only. In other words, the electric bicycle industry lacks any standard or base model that can easily be adapted to accommodate different regulations, different parts, and/or different configurations. Further, the same electric bicycle may be considered by law a bicycle, a moped, a motor assisted cycle, or a motorcycle depending on jurisdiction and specification. The most common jurisdictional variations are total power permitted, top speed permitted, and whether the motor is controlled by a hand throttle or by pedal input. 
     SUMMARY 
     Advancements in technology make it possible to develop systems of a versatile electric bicycle that are adaptable to accommodate different parts, including motors and batteries, seat configurations, and laws of different jurisdictions. 
     In one embodiment, a system for controlling an electric bicycle having a motor comprises a user access point unit configured to receive a user input for controlling the electric bicycle, and an electric bicycle computing unit configured to control performance characteristics of the electric bicycle. The electric bicycle computing unit may control the electric bicycle based on the received user input, such that the performance characteristics of the electric bicycle comply with regulations of a first jurisdiction encompassing a current location of the electric bicycle. In one embodiment, the electric bicycle computing unit may communicate with a main computing system which maintains a regulations database to retrieve the regulations of the first jurisdiction encompassing the current location of the electric bicycle and automatically configure the electric bicycle to comply with the retrieved regulations. In another embodiment, the user access point unit may communicate with a main computing system which maintains a regulations database to retrieve the regulations of the first jurisdiction encompassing the current location of the electric bicycle and transmit the retrieved regulations to the electric bicycle computing unit, and electric bicycle computing unit may automatically configure the electric bicycle to comply with the regulations transmitted by the user access point unit. 
     In some embodiments, the current location of the electric bicycle may be automatically determined, without any user input, based on location information provided by a GPS module configured to determine location information. Alternatively, in other embodiments, the current location of the electric bicycle may be determined based on the user input specifying a location. 
     In some embodiments, the user access point unit may allow the user to specify one or more control parameters for controlling the electric bicycle. The one or more control parameters may be one or more of (i) pedal assist or power on demand modes of power application, (ii) a power output of the motor, (iii) a top speed of the electric bicycle, (iv) a maximum torque of the motor, and (v) a brake ON or OFF status. 
     In some embodiments, the electric bicycle computing unit may detect a change in the current location of the electric bicycle causing the current location to be encompassed by a second jurisdiction different from the first jurisdiction, and automatically configure the electric bicycle to comply with regulations of the second jurisdiction 
     In some embodiments, the electric bicycle may further comprise power control module for controlling the power output of the motor of the electric bicycle, a GPS module for detecting a current location of the electric bicycle, a speed detection module for detecting a current speed of the electric bicycle, a navigation module for providing directions to the user, and/or a battery level detection module for monitoring a current battery level by communicating with one or more battery sensors. 
     In some embodiments, the user input may include user selection of a riding mode specifying how the electric bicycle is to be used. Based on the user selection, the electric bicycle computing unit may control the electric bicycle according to the selected riding mode. For example, (1) in a case that the riding mode is a bicycle mode, the electric bicycle computing unit turns off the motor of the electric bicycle such that the electric bicycle is driven solely by pedaling, (2) in a case that the riding mode is a moped mode, the electric bicycle computing unit caps the performance of the motor of the electric bicycle based on the regulations of the first jurisdiction, and (3) in a case that the riding mode is an off-road-only mode, the electric bicycle computing unit allows the motor of the electric bicycle to perform in an uninhibited manner. 
     In some embodiments, the electric bicycle computing unit may be configured to unlock the electric bicycle when a valid connection is established between the electric bicycle computing unit, and lock the electric bicycle when the valid connection is terminated. 
     In some embodiments, an electric bicycle may comprise a frame and a side bag having a semi-rigid outer shell. The side bag may be connected to the frame with an elastic material that holds the shell tight to the frame when the side bag is not full and holds the shell tight to the cargo inside the side bag when the side bag is full. 
     In some embodiments, the side bag is waterproof, cut resistant, permanently fixed to the frame, and/or has one or more additional pockets for holding batteries, controllers, bicycle locks and/or helmets. In some embodiments, a bag or compartment for holding one or more batteries may comprise a connector mechanism for connecting at least one battery of said one or more batteries to the electric bicycle such that the motor is powered by said at least one battery.

     DETAILED DESCRIPTION 
     Embodiments will now be described with reference to the accompanying figures. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments. Furthermore, embodiments may comprise several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the embodiments herein described. 
     The disclosure herein provides improved systems for a versatile electric bicycle that is flexible and easily adaptable to accommodate various needs and requirements. In general, most electric bicycles available today are restricted and/or designed to be used with particular parts, such as motors and/or batteries. Further, most electric bicycles are confined to a particular seating configuration and/or are not easily transferable across different jurisdictions due to varying regulations and laws that control the electric bicycle industry. However, the embodiments of a versatile electric bicycle disclosed herein provide standard features and/or models that are configured to be easily adapted to accommodate parts of varying dimensions, different seating configurations, and/or particular laws and regulations of different jurisdictions. Further, due to its flexibility, embodiments of an electric bicycle disclosed herein are durable and timeless as the motor, battery, and/or other parts of the electric bicycle can be easily upgraded and replaced. 
     The term “electric bicycle” used in the present disclosure may refer to any of electric bicycles, electric assist bicycles, mopeds and other “limited use vehicles” as defined by law (for example, a two- or three-wheeled cycle that can go faster than 30 mph and reach a top speed of 40 mph). However, the term is not limited to such examples, and may include other similar devices currently existing or to be developed in the future. 
     Frame Design 
     In an embodiment, an electric bicycle comprises an ergonomically designed frame. In some embodiments, the electric bicycle comprises a step-through frame. 
     Wave Seat Configuration 
     In general, electric bicycles can either be powered manually by pedaling or electrically by an electric motor. When an electric bicycle is powered by the electric motor, the rider may prefer to sit lower and further back for a more comfortable position while cruising. Also, it may be preferable for the rider to be able to lay his or her feet flat on the ground when the electric bicycle is stopped. Alternatively, a rider may choose to manually pedal the electric bicycle in some situations, such as when the batteries are out of power or when the motor is not providing enough power and/or speed. When pedaling, a rider may prefer to sit or stand substantially above the pedals for a more dynamic riding configuration. As such, due to differences in physical action of the two options, different riding and/or seating positions can be preferred depending on how the electric bicycle is being powered. 
     In an embodiment, an electric bicycle can have one or more seating positions that can be selected by the rider to accommodate different seating preferences.  FIGS. 1A-1G  illustrate an example of an embodiment of an electric bicycle with multiple seating positions or a wave seat configuration. In the depicted embodiment, an electric bicycle comprises multiple seating positions including at least Position A  102 , Position B  104 , and Position C  106 . 
     Position A  102  is relatively low and is positioned away from the front of the bicycle. The pedals  108  are generally located further forward than the seat position. Position A  102  can be selected when the electric motor is powering the electric bicycle, although it may be selected for manual pedaling as well. When the electric bicycle is in Position A  102 , a rider can sit back in a cruising position as the electric motor powers the bicycle. Also, in some embodiments, Position A  102  is sufficiently low as to allow a rider to rest the rider&#39;s feet flat on the ground when the bicycle is not moving. 
     Position C  106  is higher in height and is closer to the front of the bicycle compared to Position A  102 . When a rider is actively pedaling the electric bicycle, the user may select Position C  106  of the seating positions. This allows for the rider to sit or stand substantially above the pedals  108  to allow for more power and a more dynamic riding position. 
     Position B  104  is between Position A  102  and Position C  106 , both in height and in distance from the front of the bicycle. Position B  104  can be selected depending on the personal preference of the rider and/or riding condition, such as the steepness of terrain. 
     In other embodiments, any number of seating positions that differ in height and in distance from the front of the bicycle may be selected. A plurality of seating positions may accommodate riders of different heights and/or with different uses or preferences. In some embodiments, the different possible positions may be along a straight line. In other embodiments, the different possible positions may be along an arc. That is, the seat may trace a straight line shape or an arc shape when switched between the various positions. In other embodiments, the seat may trace any shaped line when switched between positions. Further, for whatever path the seat traces, any number of possible positions may be used in between the two extreme positions A  102  and C  106 . 
     In some embodiments, the seat may be rotated about an axis perpendicular to the bicycle frame plane. This plane contains the frame of the bicycle, thus such an axis would be approximately parallel to a wheel axis. This is the equivalent of a “pitch” type of rotation. Thus, such rotation of the seat allows the rider to either pitch up or pitch down. For example, when in back position A  102  a rider may elect to pitch up so that, relative to a level seat, the front portion of the seat moves up and the back portion of the seat moves down. Conversely, when in forward position  106 , a rider may elect to pitch down, so that the front portion of the seat moves down and the back portion of the seat moves up relative to a level seat. Depending on the shape of the seat, the front portion of the seat may be higher or lower than the back portion of the seat when pitched in either direction. 
     In some embodiments, the traced shape of the seat may be translated or moved. For example, for a given starting position at position A  102  and given a shape to trace, the positions B  104  and C  106  are thus defined in space. However, all three positions, or however many positions an embodiment has, may be moved together. For example, a different starting position at position A  102  may be used. Suppose position A  102  is moved up and back by a certain distance. This will in turn translate or move the shape that the seat traces up and back by the same distance, thus moving position B  104  and C  106  up and back by the same distance. In this manner, different sized riders may adjust the seat so that the various positions result in optimal configurations. For instance, a short rider may want positions that will be closer to the ground, while a tall rider may want positions higher up. These riders can adjust the seat accordingly so that all possible positions are relatively lower or higher, respectively, than they otherwise would be. The translation or movement of the traced shape may also be further forward or backward, or any combination of forward/backward and up/down. 
     In certain embodiments, the seat is configured to be switched between one or more seating configurations via an ottoman bracket and/or an L-shaped bracket. In some embodiments, the ottoman bracket and/or L-shaped bracket can comprise one or more holes that allow for one or more seat configurations. In certain embodiments, the seat is configured to be manually adjusted and locked into a particular position. In other embodiments, the seat is configured to be automatically moved and locked into a preferable position via a button or other input that a rider can select. 
     In some embodiments, the vertical distance of the seat from the bottom of the wheels can be adjusted from about 25 inches to about 45 inches or any other range. For example, depending on the seat configuration, the vertical distance of the seat from the bottom of the wheels can be about 25 inches, 26 inches, 27 inches, 28 inches, 29 inches, 30 inches, 31 inches, 32 inches, 33 inches, 34 inches, 35 inches, 36 inches, 37 inches, 38 inches, 39 inches, 40 inches, 41 inches, 42 inches, 43 inches, 44 inches, 45 inches, or any other height. 
     In certain embodiments, the horizontal distance from the front of the seat to the handles of the electric bicycle can be adjusted from about 10 inches to about 25 inches or any other range. For example, depending on the seat configuration, the horizontal distance from the front of the seat to the handles of the electric bicycle can be about 10 inches, 11 inches, 12 inches, 13 inches, 14 inches, 15 inches, 16 inches, 17 inches, 18 inches, 19 inches, 20 inches, 21 inches, 22 inches, 23 inches, 24 inches, 25 inches, or any other distance. 
     Bag(s) Configuration 
     In an embodiment, an electric bicycle comprises one or more bags configured to hold cargo or any other item(s).  FIGS. 2A-2G  illustrate an example of an embodiment of an electric bicycle comprising one or more bags. 
     In an embodiment, one or more bags  200  are located in the rear of the electric bicycle. In some embodiments, the one or more bags  200  are permanently or semi-permanently integrated to the electric bicycle. In other embodiments, the one or more bags  200  or parts thereof are selectively removable from the electric bicycle. 
     In some embodiments, the one or more bags  200  cover the rear wheel or portions thereof, providing a protective cover for the rear wheel. By covering the rear wheel or portions thereof, the one or more bags  200  can reduce exposure of the rider and/or rear wheel to dirt or other debris. The one or more bags  200  can also function as a protective layer for the rear wheel against shock or damage. 
     In some embodiments, the one or more bags  200  comprise a hard shell and/or soft compartment or pouch. The hard shell or structure can be made of any type of hard material, such as a hard plastic for example. The hard shell can provide a rigid structure to the one or more bags  200  such that the one or more bags  200  can maintain a certain form and/or shape. Also, the hard shell can prevent the one or more bags  200  from poking into the rear wheel frame. 
     In some embodiments, the one or more bags  200  comprise a semi-rigid outer shell connected to a main body of the bag with an elastic material. The elastic material can be configured to hold the outer shell tight or close to the body when the bag is not full, and to hold the shell tight to cargo placed within the bag when the bag is full or partially full. In some embodiments, the bags  200  are configured to be waterproof and/or cut resistant. In some embodiments, the bags  200  are permanently fixed to the bicycle frame or removably attached to the bicycle frame. In some embodiments, as further described below, the bags  200  may comprise one or more internal or external pockets for holding various items, such as, for example, batteries, a controller, and/or dirty locks. In some embodiments, one or more pockets are specially configured to hold a particular item, such as a battery, controller, dirty locks, and/or the like. For example, a special pocket for holding a dirty lock may comprise waterproof or other materials and/or a seal to reduce a risk of transferring dirt, contaminants, and/or moisture from the lock to other items within the bag. 
     The soft compartment or pouch can be made of any soft material, such as any type of fabric, soft plastic, canvas, leather, or any other appropriate material or trim. The soft compartment or pouch can be flexible in some embodiments to be able to carry a wide variety of items in size and dimension. In certain embodiments, when empty, the soft compartment or pouch collapses to lay flat against the hard shell and closer to the rear wheel. This can allow for a more aerodynamic configuration of the electric bicycle. In contrast, in certain embodiments, when one or more items are placed in the soft compartment or pouch, the soft compartment or pouch can expand while being supported by the hard shell. 
     In certain embodiments, an electric bicycle comprises a platform  204 . The platform  204  can be configured to be used for resting a rider&#39;s feet and/or for providing support for the soft compartment or pouch. 
     Dedicated Pockets 
     In some embodiments, the one or more bags  200  comprise one or more compartments or pouches that are dedicated for particular items. For example, in certain embodiments, the one or more bags  200  can comprise one or more dedicated battery pouches or compartments  202  for battery mounting and suspension on one or both sides of the electric bicycle. In other embodiments, the one or more bags  200  can comprise one or more dedicated compartments or pouches for a bicycle lock and/or helmet. For example, the one or more bags  200  may be used to hold or store dirty locks. 
     In certain embodiments, the one or more bags  200  comprise a plurality of dedicated battery compartments  202  in various locations. In some embodiments, the compartments  202  are on one or both sides of the bags  200 . In other embodiments, the compartments may be, instead or in addition to being on the sides, on the back end of the bags  200  that is farthest from the handles on the bike. Still in other embodiments, the compartments  202  may be on a front side of the bags  200  that is farthest toward the handles of the bike. Or the compartments  202  may be in any combination of front, side, and/or back locations on the bags  200 . The compartments  202  may further by located in any of these positions on both or either the exterior of the bags  200  and/or the interior of the bags  200 . In some embodiments, the bags  200  may also include covers to protect the bags  200  from the elements and/or hide the bags  200  from view for security purposes. 
     In certain embodiments, the one or more bags  200  comprise a plurality of dedicated battery compartments  202  of various shapes and sizes to accommodate batteries of various shapes and sizes. In some embodiments, the battery compartments  202  are substantially rectangular in shape and are configured to hold a plurality of batteries shaped approximately like a brick and of various sizes. For instance, the compartments  202  may be configured to hold batteries approximately shaped like a brick and/or rectangle with width, depth, and length dimensions, respectively, of about 3.375 inches by about 2.625 inches by about 10.250 inches. Other possible width dimensions include about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, or about 6 inches, or any other width. Other possible depth dimensions include about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, or about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, or about 6 inches, or any other depth. Other possible length dimensions include about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, about 6.5 inches, about 7 inches, about 7.5 inches, about 8 inches, about 8.5 inches, about 9 inches, about 9.5 inches, about 10 inches, about 10.5 inches, about 11 inches, about 11.5 inches, about 12 inches, about 12.5 inches, about 13 inches, about 13.5 inches, about 14 inches, about 14.5 inches, about 15 inches, about 15.5 inches, about 16 inches, about 16.5 inches, about 17 inches, about 17.5 inches, or about 18 inches, or any other depth. 
     The compartments  202  may be sized to accommodate a single size and shape of battery or the compartments  202  may be sized to accommodate many ranges of battery sizes and shapes. In other embodiments, the battery compartments  202  are substantially square, circular, and/or oval in shape, and/or any other shape, whether typical or atypical. 
     Square-shaped compartments may have length and width dimensions of about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, about 6.5 inches, about 7 inches, about 7.5 inches, about 8 inches, about 8.5 inches, about 9 inches, about 9.5 inches, about 10 inches, about 10.5 inches, about 11 inches, about 11.5 inches, about 12 inches, about 12.5 inches, about 13 inches, about 13.5 inches, about 14 inches, about 14.5 inches, about 15 inches, about 15.5 inches, about 16 inches, about 16.5 inches, about 17 inches, about 17.5 inches, or about 18 inches, or any other length and width. Square-shaped compartments  202  may have height dimensions of about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, or any other height. 
     Circular-shaped or oval-shaped compartments  202  may have a minimum diameter and/or a height of about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, about 6.5 inches, about 7 inches, about 7.5 inches, about 8 inches, about 8.5 inches, about 9 inches, about 9.5 inches, about 10 inches, about 10.5 inches, about 11 inches, about 11.5 inches, about 12 inches, about 12.5 inches, about 13 inches, about 13.5 inches, about 14 inches, about 14.5 inches, about 15 inches, about 15.5 inches, about 16 inches, about 16.5 inches, about 17 inches, about 17.5 inches, or about 18 inches, or any other diameter and/or height. 
     In certain embodiments, the dedicated battery compartments  202  are diagonal or substantially vertical in configuration with an opening at the top to allow for easy installation and removal while providing sufficient stability such that the battery does not fall out. 
     In some embodiments, an electric bicycle comprises a plurality of battery compartments  202  on one or multiple sides of the electric bicycle. For example, in some embodiments, one, two, or three battery compartments  202  may be located on each side of the electric bicycle. In other embodiments, more battery compartments  202  may be located on one side compared to another side. In certain embodiments, one or more battery compartments  202  may be located on only one side of the electric bicycle. 
     In some embodiments, a dedicated battery compartment(s)  202  further comprises a connector mechanism to connect the battery to the electric bicycle such that battery can power the electric motor. For example, a dedicated battery compartment(s)  202  can comprise a cradle, dock, cable(s), and/or pin(s) for connecting the battery to the electric bicycle. A battery compartment(s)  202  can also comprise any other battery connecting mechanism that is currently well-known or is to be developed in the future. In some embodiments, the battery connecting mechanism that connects the one or more batteries to the motor is protectively covered by the one or more bags  200 . 
     In certain embodiments, unlike some other electric bicycles that are restricted to a proprietary battery, a number of different types of batteries can be installed. Dedicated battery compartments  202  of some embodiments are flexible in shape and/or size and can accommodate batteries with varying shapes and/or sizes. In addition, in certain embodiments, a dedicated battery compartment  202  can allow for simple installation and/or removal of batteries for recharging, replacing, and/or upgrading among other purposes. 
     The bags  200  and/or compartments  202  in some embodiments are aerodynamically shaped to minimize and/or lower drag on the bike when moving and thus increase efficiency of the electrical system. In other embodiments, the bags  200  and/or compartments  202  are bulkier and sacrifice aerodynamic efficiency for more storage space. 
     Vehicle Control System 
     Currently, different states and/or countries have different laws governing the use of electric bicycles. For example, the definition and/or restrictions of electric bicycles and their power can be different in each state and/or country. Laws regarding the maximum speed of electric bicycles can also be different. For example, the U.S. federal law defines and restricts electric bicycles to bicycles with electric motors of less than 750 Watts and with a top motor-powered speed of less than 20 miles per hour with a rider that weighs less than 170 pounds. In comparison, California restricts the maximum power output of electric bicycles to 1000 Watts, and Florida allows electric bicycles with a maximum power output of up to 5000 Watts. 
     Needless to say, the different laws and regulations of each jurisdiction create a challenge for electric bicycle manufacturers in creating a single product that complies with all such rules. One option for manufacturers is to develop a low-powered electric bicycle that complies with the regulations of all jurisdictions and can be sold everywhere. However, such electric bicycles are unnecessarily restricted in both power and/or speed and consequently may not appeal to consumers thereby hindering sales. Another option is to develop customized electric bicycle products for each jurisdiction to maximize the power and/or speed allowed by the laws of each jurisdiction. However, this option inherently leads to high costs in design and manufacturing of multiple models. 
     As an alternative to developing a sufficiently low-powered electric bicycle to comply with all state regulations or developing customized electric bicycles per jurisdiction, an embodiment of an electric bicycle as disclosed herein uses software and a computer system(s) to control the maximum power output and/or speed within the regulations of each jurisdiction. In other words, in some embodiments, an electric bicycle with hardware specifications above the regulations of one or more jurisdictions is adaptable to such regulations via software and a computer system(s). Such electric bicycles can maximize the power and/or speed limits allowable by the laws of each jurisdiction. In this way, a manufacturer of an electric bicycle only needs to design, build, and market one electric bicycle product for a plurality of jurisdictions as long as the software and computer system(s) can limit the maximum power and/or speed output of the electric motor within each jurisdiction&#39;s regulations. 
       FIG. 3A  is a block diagram illustrating a high level overview of one embodiment of a system for controlling the output of an electric bicycle&#39;s motor within a jurisdiction&#39;s regulations. In an embodiment, a main computing system  304 , an electric bicycle computing system  310 , and/or a user access point system  324  can be in communication over a network  308  to control the output of an electric bicycle&#39;s motor. For example, in some embodiments, a main computing system  304 , an electric bicycle computing system  310 , and/or a user access point system  324  are configured to control the performance characteristics of an electric bicycle such that the performance characteristics comply with a particular jurisdiction or government&#39;s regulations and requirements. In certain embodiments, appropriate software configured to be used in conjunction with the system to control and/or monitor an electric bicycle&#39;s performance can be purchased and/or downloaded for installation. For example, in some embodiments, software for a user access point system  324  can be downloaded and installed from a mobile app store. 
     In some embodiments, the system comprises a user access point system  324  configured to receive input from a rider and/or other user to specify one or more control parameters for controlling the electric bicycle. Such control parameters may include “pedal assist” or “power on demand” modes of power application (for example, pedal-assist mode in which the motor assists the rider based on the pressure of his or her pedaling, and power-on-demand mode in which the rider has control of the amount of power output by the motor), total power output (for example, in watts), top speed, maximum torque and/or brake on or off status. Additionally or alternatively, the system (for example, electric bicycle computing system  310 ) may be configured to determine one or more of such control parameters based on information provided by the user (for example, via the user access point system  324 ) and/or information retrieved from one or more internal or external databases (for example, regulations databases  306  or  322 ). For example, in certain embodiments, the rider and/or other user can input a maximum speed and/or power value for the motor. In other embodiments, the rider and/or other user can input and/or select the state or other jurisdiction where the electric bicycle is located, and the system can be configured to automatically configure the one or more control parameters such that the electric bicycle complies with the regulations of the particular state or jurisdiction. In some embodiments, the system can be configured to automatically detect the appropriate state or other jurisdiction, without requiring a user to manually input and/or select a state or other jurisdiction. For example, as further described below, the system can be configured to utilize a GPS module to detect the bike&#39;s location. 
     In some embodiments, the user access point system  324  determines the maximum speed and/or power output allowable under the appropriate regulations of the selected jurisdiction based on a regulations database  322  of the user access point system  324 . In other embodiments, the user access point system  324  communicates with a main computing system  304  comprising a regulations database  306  to determine the maximum speed and/or power output allowable under the appropriate regulations of the selected jurisdiction. Regulations related to electric bicycles, maximum allowable power and/or speed of electric bicycles, and/or other related information can be stored in the regulations database  306 ,  322 . The user access point system  324  and/or main computing system  304  can be configured to periodically update the one or more regulations databases  306 ,  322  by communicating with one or more other computing systems and/or databases. 
     In certain embodiments, a GPS module is configured to detect the current location of the electric bicycle and electronically transmit the location to the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304 . Based on the detected location, the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304  can automatically access the regulations database and determine the maximum speed and/or power output allowed under the appropriate regulations of the jurisdiction where the electric bicycle is currently located. In some embodiments, the GPS module is configured to periodically check the location of the electric bicycle and electronically transmit the location to the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304 . Based on the periodically updated location of the electric bicycle, the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304  can update the maximum speed and/or power output allowed under the regulations of a new jurisdiction when necessary due to the electric bicycle&#39;s movement. In some embodiments, the GPS module is part of a user&#39;s smartphone or other portable computing device. In some embodiments, in addition to, or in lieu of a GPS module, other locating or geolocation methods may be utilized, such as, for example, cellular phone tower triangulation, detection of Wi-Fi access points or other radio devices or broadcasts, and/or the like. 
     In some embodiments, an electric bicycle comprises an electric bicycle computing system  310 . In certain embodiments, an electric bicycle computing system  310  is configured to limit the maximum power and/or speed of the electric bicycle according to the determined maximum allowable power and/or speed from one or more regulations databases  306 ,  322 . In certain embodiments, the electric bicycle computing system  310  comprises a power control module  312  configured to control and/or limit the maximum power output of the electric bicycle&#39;s motor. The electric bicycle computing system  310  can also comprise a speed control module  314  configured to control and/or limit the maximum speed output of the motor. 
     In some embodiments, some or all data and user settings are logged, time/date stamped, and preserved for a period of time (for example, to preserve manufacturer liability in the event of a crash or misuse). For example, every time a location-based performance profile is created (for example, either from user specification of the location information or specific control parameters, or from automatic determination of location information and automatic configuration of relevant control parameters), any data generated and settings specified by the user are logged in a log database. In some embodiments, other data is also logged, such as speed, acceleration, distance traveled, throttle position, brake control position, distance from nearby vehicles, and/or the like. The system may be configured to periodically back up to another server or system for storage or analysis the data stored in the log database. 
     In certain embodiments, the user access point system  324  can be configured to enable the user (for example, rider) of the electric bicycle to select a riding mode from a plurality of riding modes such as a “bicycle” mode, a “moped” mode or an “off road only” mode. In one embodiment, the bicycle mode may, for example, turn off or disconnect the motor of the electric bicycle and enable driving the electric bicycle solely from pedaling, the moped mode may, for example, limit the capacity of the electric bicycle (for example, top speed, motor output, etc.) such that the electric bicycle falls under the definition of a moped (for example, the power control module  312  may be configured to limit the power output and/or speed of the electric bicycle to be within the limits defined by law), and the off-road-only mode may, for example, allow uninhibited top speed and/or motor output. 
     In certain embodiments, the electric bicycle computing system  310  and/or user access point system  324  comprises a speed detection module  316  configured to detect the current speed of the electric bicycle. The detected speed of the electric bicycle can be displayed to the rider via the user access point system  324  and/or other display means. 
     In certain embodiments, the electric bicycle computing system  310  and/or user access point system  324  comprises a navigation module  318  configured to communicate with a GPS module, detect the current location of the electric bicycle, and/or give directions to the rider. Directions can be displayed to the rider via the user access point system  324  and/or other display means. 
     In certain embodiments, the electric bicycle computing system  310  and/or user access point system  324  comprises a battery level detection module  320  configured to detect and/or monitor the current battery level by communicating with one or more battery sensors. In some embodiments, the electric bicycle computing system  310  is further configured to estimate a remaining distance or range the electric bicycle can travel based on the detected battery level. In some embodiments, the current battery level and/or estimated range is displayed to the rider via the user access point system  324  and/or other display means. 
     In certain embodiments, the electric bicycle computing system  310  and/or user access point system  324  are configured to control the suspension settings of the electric bicycle. In some embodiments, the user access point system  324  can display a suspension setting input field to a rider. The rider can insert a suspension setting of the rider&#39;s choice using the user access point system  324 . In certain embodiments, the user access point system  324  is configured to receive a suspension setting selection from a rider and transmit the selection to the electric bicycle computing system  310 . The electric bicycle computing system  310  can receive the selection input and control the electric bicycle accordingly. 
     For example, in some embodiments, an electric bicycle can be configured to have one or more suspension settings, such as soft, medium, or hard. If a rider selects the soft suspension setting, the electric bicycle computing system  310  can loosen the suspension settings of the electric bicycle by adjusting a shock absorbing mechanism of the electric bicycle. If a rider selects the hard suspension setting, the electric bicycle computing system  310  can tighten the suspension settings of the electric bicycle by adjusting a spring and/or shock absorbing mechanism of the electric bicycle. 
     The network may comprise one or more internet connections, secure peer-to-peer connections, secure socket layer (SSL) connections over the internet, virtual private network (VPN) connections over the internet, or other secure connections over the internet, private network connections, dedicated network connections (for example, IDSN, T1, or the like), wireless or cellular connections, or the like or any combination of the foregoing.

       FIGS. 3C-3I  illustrate an example of an embodiment of an electric bicycle that is configured to be coupled with a user access point or user access point system  324  for controlling the electric bicycle. In some embodiments, the user access point system  324  can be permanently and/or semi-permanently installed. In other embodiments, the user access point system  324  is a mobile device that can be selectively installed and/or removed. In some embodiments, the user access point system  324  comprises more than one separate computing device, such as, for example, a cellular phone or smartphone configured to be carried by a user and to electronically communicate, wired and/or wirelessly, with a separate computing device configured to be permanently or removably attached to the electric bicycle. In some embodiments, a user access point system  324  is configured to communicate with the electric bicycle computing system  310  wirelessly. For example, the user access point system  324  may comprise a smartphone configured to be carried by a user and to wirelessly communicate with the electric bicycle computing system  310 . 
     In some embodiments, a user access point system  324  is configured to be attached and installed to the electric bicycle via a connector mechanism  302 . In some embodiments, the connector mechanism  302  comprises a cradle or a case that is configured to hold the user access point system and a data port configured to connect the user access point system  324  to the electric bicycle computing system  310 . The cradle or case  302  can be permanently or semi-permanently attached to the frame of the electric bicycle. 
     In some embodiments, the user access point system  324  can comprise software that allows the rider to select or set a maximum output of the electric motor&#39;s power and/or speed. For example, using the software and/or user interface, the rider can set the maximum output of the electric bicycle&#39;s power to about or exactly 250 watts (currently the most common requirement in Europe), about or exactly 500 watts, about or exactly 600 watts, about or exactly 700 watts, about or exactly 750 watts, about or exactly 800 watts, about or exactly 900 watts, about or exactly 1000 watts, about or exactly 1100 watts, about or exactly 1200 watts, about or exactly 1300 watts, about or exactly 1400 watts, about or exactly 1500 watts, about or exactly 2000 watts, about or exactly 3000 watts, about or exactly 4000 watts, about or exactly 5000 watts or any other value. 
     In certain embodiments, the software and/or user interface of the user access point system  324  is configured such that a user only needs to select a state or jurisdiction where the user is currently located. The user access point system  324  in certain embodiments comprises a pre-stored database that comprises data of each jurisdiction&#39;s electric bicycle regulations and/or laws. For example, a user access point system  324  can have pre-stored the maximum power and/or speed of electric bicycles allowed by law of one or more jurisdictions. In other embodiments, data related to the maximum power and/or speed of electric bicycles allowed by law of one or more jurisdictions is stored in the electric bicycle computing system  310  and/or main computing system  304 . 
     In some embodiments, when a rider selects a particular jurisdiction, the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304  is configured to determine the maximum power and/or speed limit of the selected jurisdiction using a pre-stored database and restrict the electric bicycle accordingly. For example, if a rider inputted via the user access point system  324  that the rider is currently in California, the user access point system  324 , electric bicycle computing system  310 , and/or main computing system  304  can be configured to automatically determine or identify that the maximum power output for electric bicycles in California is 1000 watts and limit the power output of the electric motor to 1000 watts. 
     In certain embodiments, the user access point system  324  and/or electric bicycle computing system  310  comprises a GPS module which is configured to automatically and/or periodically determine the location of the electric bicycle, identify the maximum power and/or speed allowed by the appropriate jurisdiction&#39;s regulations, and limit the power and/or speed of the electric bicycle to that value(s). For example, if the user access point system  324  and/or electric bicycle computing system  310  determines that the electric bicycle is currently in California, the user access point system  324  and/or electric bicycle computing system  310  can automatically identify that the maximum power output in California is limited to 1000 watts and restrict the power output to 1000 watts. When the user access point system  300  and/or electric bicycle computing system  310  determines that the electric bicycle is in New York at a later point in time, the user access point system  324  and/or electric bicycle computing system can then automatically determine that the electric bicycle is currently in New York and restrict the maximum power and/or speed of the electric bicycle to the maximum value(s) allowed in New York. 
     In certain embodiments, the user access point system  324  can be configured to provide additional features as well. For example, the user access point system  324  can be configured to function as a speedometer and display the current speed of the electric bicycle to the user. In some embodiments, the user access point system  324  can also provide a GPS navigation system and/or map to the user via a GPS module. Furthermore, in certain embodiments, the user access point system  324  can be configured to provide driving education software to the user for efficient driving. 
     In addition, in some embodiments the user access point system  324  is configured to function as a key for locking and/or unlocking the electric bicycle. For example, when a rider attaches and/or installs the user access point system  324  into the electric bicycle, the electric bicycle computing system  310  can be configured to validate the identity of the user access point system  324  and unlock the electric bicycle if validated. Similarly, when a rider removes the user access point system  324  from the electric bicycle in certain embodiments, the electric bicycle computing system  310  can be configured to automatically detect that the user access point system  324  is removed and lock the electric bicycle. 
     Methods of Controlling Maximum Output 
       FIG. 3J  illustrates an overview of one embodiment of a method of controlling the maximum output of a motor of an electric bicycle. In some embodiments, a user and/or rider inputs or selects via a user access point system a jurisdiction where the electric bicycle is located at block  344 . In certain embodiments, the user access point system is configured to display only certain jurisdictions, such as certain states and/or countries. In other embodiments, the system is configured to automatically detect the jurisdiction. 
     In certain embodiments, the electric bicycle computing system communicates with a main computing system and/or other database(s) for any regulation updates at block  346 . In some embodiments, the main computing system communicates with one or more regulations databases  350  to obtain the most recent regulations. In certain embodiments, the user access point system only communicates with the main computing system for updates only when necessary or periodically at predetermined intervals. In other embodiments, the user access point system does not communicate with the main computing system for updates. 
     In some embodiments, the user access point system determines the maximum speed and/or power output allowed for an electric bicycle under the updated, if any, regulations of the selected jurisdiction at block  352 . An electric bicycle computing system in certain embodiments can limit the maximum speed and/or power of the electric bicycle according to the determined legal limits at block  354 . 
     In certain embodiments, the user access point system displays the set maximum power and/or speed to the rider at block  356  for confirmation. If the rider confirms, then the maximum speed and/or power output of the electric bicycle is set to the maximum level allowable under that jurisdiction&#39;s regulations. In some embodiments, the user access point system is configured to display to the rider or user an option to even lower the maximum power and/or speed of the electric bicycle below the jurisdiction&#39;s legal limits at block  358 . For example, a parent may decide to further limit the maximum power and/or speed of a child&#39;s electric bicycle. 
     In some embodiments, if a rider or user selects a lower maximum speed and/or power limit of the electric bicycle at block  358 , the electric bicycle computing can then limit such to the selected level at block  360 . In certain embodiments, the user access point system confirms the lower maximum speed and/or power value selected at block  362 . 
     Motor Placement 
     Generally, most electric bicycles comprise a hub-motor that is located within the rear wheel frame of the electric bicycle. However, such designs have many disadvantages. For example, because hub-motors cannot be configured to be used with gears, a specially designed low RPM motor must be used for placement inside the rear wheel frame. Also, the weight of the hub-motor naturally affects the weight of the rear wheel and affects the dynamics of the electric bicycle. In addition, due to the restrictions in size and placement, only motors of a particular size and/or configuration may be installed in such electric bicycles. Further, it can be difficult to remove and/or install a hub-motor due to its placement inside the rear wheel frame. In some cases, the whole rear wheel has to be replaced in order to replace a hub-motor. 
     In contrast, in an embodiment of an electric bicycle, the electric motor is placed outside the rear wheel frame. In some embodiments, the electric motor is placed substantially beneath the seat frame.  FIGS. 4A-4G  illustrate an example of an embodiment of an electric bicycle where the electric motor  412  is located beneath the seat and is attached directly to the bicycle frame itself. In some embodiments, the motor  412  is located substantially above a jackshaft  404 . 
     By locating the motor  412  outside of the rear wheel frame, such embodiments of an electric bicycle are more flexible and adaptable as they can be used with a wider range of motors. For example, because the motor  412  is not located within the rear wheel frame, the motor  412  can be configured to be used in conjunction with hinge gears, which allows use of a number of conventional motors that are not necessarily specially designed for low RPM. Also, there are less weight restrictions as the weight of the wheel itself is not affected by the motor  412 . In addition, motors  412  with a wider range of sizes and/or configurations can be installed. Further, it is easier to remove and/or install a motor  412 . 
     Drivetrain Design 
     In some embodiments, the drivetrain of an electric bicycle is chain-free and comprises belt drives  402 ,  410 ,  414 . In some embodiments, one or more belt drives  402 ,  410 ,  414  of the electric bicycle or portions thereof are covered. For example, in some embodiments where one or more bags  200  are located in the rear of the bicycle, one or more belt drives  402 ,  410 ,  414 , jackshaft  414 , motor  412 , and/or portions thereof may be protectively covered by portions of one or more bags  200 . 
     In certain embodiments, an electric bicycle is configured such that there is complete independence between the electric motor  412  and pedals  108 . For example, in some embodiments, there is no or substantially no resistance to the pedals  108  from the motor  412  when the motor is powering the electric bicycle. In certain embodiments, when the electric bicycle is powered by the motor  412 , the motor  412  moves a first belt drive  410 , which further turns a jackshaft  404 . As the jackshaft  404  is turned, a second belt drive  414  is moved thereby turning the real wheel  408 . 
     In some embodiments, when the pedals  108  are moved to power the electric bicycle, the pedals  108  move a third belt drive  402  which further turns a jackshaft  404 . In some embodiments, an electric bicycle comprises an idler  406  contacting the third belt drive  402 . In some embodiments, the same jackshaft  404  is turned by both manual pedaling  108  and the electric motor  412 . As the jackshaft  404  is turned, the second belt drive  414  is moved thereby turning the rear wheel  408 . 
     In some embodiments, the first, second, and third belt drives  410 ,  414 ,  402  substantially form a T-shape with the jackshaft  404  located at the intersection. In certain embodiments, the angle between the first and second belt drives  410 ,  414 , the first and third belt drives  410 ,  402 , and/or the second and third belt drives  414 ,  402  is about 5°, about 10°, about 15°, about 20°, about 25°, about 30°, about 35°, about 40°, about 45°, about 50°, about 55°, about 60°, about 65°, about 70°, about 75°, about 80°, about 85°, about 90°, about 95°, about 100°, about 105°, about 110°, about 115°, about 120°, about 125°, about 130°, about 135°, about 140°, about 145°, about 150°, about 155°, about 160°, about 165°, about 170°, about 175°, about 180°, or any other angle. 
     In some embodiments, the third belt drive  402  is located on one side of the electric bicycle and the first and second belt drives  410 ,  414  are located on the other side of the electric bicycle. In other embodiments, the second belt drive  414  is located on one side of the electric bicycle and the first and third belt drives  410 ,  402  are located on the other side of the electric bicycle. In certain embodiments, the first belt drive  410  is located on one side of the electric bicycle and the second and third belt drives  414 ,  402  are located on the other side of the electric bicycle. In other embodiments, the first, second, and third belt drives  410 ,  414 ,  402  are all located on the same side of the electric bicycle. 
     In some embodiments, the various belt drives are on pulleys attached to the various axles. For instance, a first belt drive  410  may be on a pulley connected to the electric motor  412  and on a pulley connected to the jackshaft  404 . An axle is connected to this pulley on the jackshaft  404  which connects to other pulleys on the axle. Among these other pulleys, one pulley may be connected to the second belt drive  414  and another pulley connected to the third belt drive  402 . The jackshaft  404  and axle may have more or less pulleys in various arrangements and locations, depending on the arrangements and locations of the various belt drives. 
     Shock Linkage 
     In an embodiment, the rear wheel suspension of the electric bicycle uses shock linkage instead of direct shock. By using a shock linkage instead of a direct shock it is possible to withstand a wide range of loads by making slight adjustments.
