A rear drive transmission system for a motorcycle includes a driving wheel, a center wheel, and a driven wheel. The center wheel includes a transmission wheel A and a transmission wheel B that are coaxially arranged. The transmission wheel A is fixedly connected to an opposite surface of the transmission wheel B. The driving wheel is drivingly connected to the transmission wheel B. The transmission wheel A is drivingly connected to the driven wheel, and the driving wheel is detachably and fixedly connected to an output shaft of a motor or engine. The driven wheel is detachably connected with a rear wheel shaft of the motorcycle. The center wheel is rotatably connected with a rear fork rotation center shaft through a bearing. The motorcycle is with the motorcycle rear drive transmission system.

The invention relates to a control device for controlling an engine driven transport apparatus. The control device comprises a fitness apparatus having a base part and at least one movable part movable with respect to the base part for enabling a user to perform a physical exercise. The control device further comprises a sensor device for sensing a degree of physical exercise. The control device is arranged for controlling engine power of an engine of the transport apparatus at least partly based on the sensed degree of physical exercise. The fitness apparatus comprises a flywheel rotatably connected to the base part. The fitness apparatus is arranged for setting the flywheel into motion by means of at least one of the one or multiple movable parts. The sensor device is arranged to sense the degree of performed physical exercise at least partly by sensing a degree of motion of the flywheel.

Wireless power transfer for integrated cycle drive systems is described. A cycle power system includes a rim that is connected to, and positioned concentrically with, a sealed housing that can rotate about an axis. The cycle power system also includes an integrated drive system disposed within the housing. The integrated drive system includes a battery and a motor for driving a cycle by causing rotational movement of the rim about the axis. Additionally, the cycle power system includes an inductive structure that is disposed within the housing, and that wirelessly charges the battery through induction between the inductive structure and remote a charging station.

A bicycle control device comprises a seat information generator and an assist controller. The seat information generator is configured to generate seat information. The assist controller is configured to control an assist actuator to assist a driving force of a bicycle based on the seat information.

Vehicle including a frame, a seat mounted to the frame, wheels rotatably mounted on the frame, and drive mechanisms for causing rotation of one wheel. Each drive mechanism includes an arm pivotally attached to the frame at one end, a weight and attached pedal at an opposite end of the arm, and a guide member including a bump and that moves in conjunction with movement of the weight. The guide member has a first end region at which the guide member is pivotally attached to the frame and a second, opposite end region which is free. A roller attached to the arm moves along the guide member during pivotal movement of the arm to cause pivoting of the guide member as the roller engages with the bump. An energy transfer system converts pivotal movement of the guide member into motive power to rotate the wheel.

Vehicle includes a frame, a seat arranged on the frame, a wheel rotatably mounted on the frame, an elongate directional slider, a pedal on the directional slider that slides between first and second positions, a main drive chain connected to the first wheel, a main drive sprocket that rotates the main drive chain and thus the first wheel, a flywheel that rotates the main drive sprocket, and an energy generating system that converts sliding of the pedal on the directional slider into rotational force to rotate the flywheel. The energy generating system may include a first electrical coil assembly connected to the pedal, a second electrical coil assembly in connection with the directional slider and that cooperates with the first electrical coil assembly to cause generation of electricity, and an electrical motor that is powered by the generated electricity and is coupled to the flywheel to rotate the flywheel.

The invention relates to a single-track land vehicle, which is designed, for example, as a bicycle (1), electric bike or electric scooter and has a vehicle frame (2) and a vehicle fork (5), which (5) has a fork steerer tube (4), which fork steerer tube (4) is mounted pivotably in a head tube (3) of the vehicle frame (2), wherein it is possible by means of a pivoting-angle brake or limiter (6) to at least decelerate the pivoting in of the vehicle fork (5) relative to the vehicle frame (2) and/or to define the maximum pivoting-in angle. For the single-track land vehicle according to the invention, it is characteristic that the pivoting-angle brake or limiter (6) has a tension element (7), which (7) is connected to the vehicle frame (2) via a holding element (8) held in the interior of the vehicle frame (2) or held on the vehicle frame, and that a holding counter-element (9) is provided on the tension element (7) at a distance from the holding element (8), which (9) rests or strikes against the vehicle fork (5) or against the fork steerer tube (4) when the pivoting-angle brake or limiter is activated (cf. FIG. 5).

A gerbilling-proof monowheel vehicle comprises: (a) a wheel felloe with a tire thereon; (b) a frame rotatably mounted within the wheel felloe; the frame carrying a passenger seat; (c) moving means configured for propelling the gerbilling-proof monowheel vehicle; and (d) braking means configured for decelerating the gerbilling-proof monowheel vehicle. The gerbilling-proof monowheel further comprises at least two auxiliary wheels side-mounted on the frame for vertically stabilizing the passenger seat and preventing the gerbilling-proof monowheel from side tipover and maintaining said passenger seat in a horizontal position within said wheel felloe.
