The wearable mechanism has a pedal, a pedal fixation rack, calf supporting plates, and magnetic pieces or belt and buckle. The shock reduction mechanism has a spring seat, springs and a cover. The drive mechanism has a motor having a hollowed center, and also an inner wall of a bearing. The motion transmission mechanism has an outer wall of the bearing, a wheel hub, and a rubber tire. The power mechanism has batteries, battery smart protection control board, ports and connection wires. The control mechanism is a single board unit with microprocessor, angular speed sensor, acceleration sensor, pressure sensor and relevant electronic components.

A bicycle control apparatus is provided that can improve the stability of the behavior of a bicycle. The bicycle control apparatus includes a controller configured to reduces an output of a motor that assists a manual drive force, upon determining a pitch angle of a bicycle body becomes greater than or equal to a prescribed angle, or based on a state of a suspension that absorbs vibrations of a bicycle, or upon determining a load that is applied to a rear wheel of a bicycle becomes less than a prescribed load.

A human-powered vehicle control device for a human-powered vehicle comprises an electronic controller. The electronic controller is configured to control a motor, which applies a propulsion force to the human-powered vehicle, in accordance with a human driving force input to the human-powered vehicle. The electronic controller is configured to control the motor to change at least one of a maximum value of an output of the motor, a first changing ratio of an increase rate of the output of the motor to an increase rate of the human driving force, and a second changing ratio of a decrease rate of the output of the motor to a decrease rate of the human driving force in accordance with transmission information related to a transmission ratio in a power transmission path between an input rotational shaft of the human-powered vehicle and a wheel of the human-powered vehicle.

Described herein are systems and methods for motorbike collision avoidance. One or more sensors or devices can be used to monitor the operating conditions of a motorbike and, upon a determination that a collision or drop has occurred, or is likely to occur, an alert system can be activated. The alert system can comprise one or more auxiliary illumination devices and/or acoustic devices configured to draw the attention of other motorists. The alert system may aid the other motorists in noticing the motorbike and approximating the motorbike's position, size, distance, or speed. The alert system can also be activated by the motorbike rider to communicate to other motorists that the rider believes a collision is possible or that a situation requires caution.

In a method for detecting a maintenance situation on a two-wheeled vehicle having a motor provided in order to assist forward motion of the two-wheeled vehicle at least at times, a maintenance situation is detected by sensing the position of the two-wheeled vehicle by way of a first sensor variable. Control is then applied to the motor either as a reduction in the applied drive power output, e.g. in the form of the motor speed or torque, or as a complete shutoff or immobilization of the motor.

A motorcycle including a frame to which an internal combustion engine is associated, from which internal combustion engine at least one exhaust pipe of combusted gases departs, the exhaust pipe having an open terminal, the frame mounted on a front wheel and a rear wheel, a control board or unit included, for controlling torque produced by the engine and other parameters such as velocity of the vehicle and spatial position thereof with respect to the road surface. The motorcycle including a system to verify when the front wheel of the motorcycle detaches from the road surface during acceleration. The system includes a choke for partialising the section of the exhaust gases outlet area from the exhaust pipe, during partialisation. The partialisation obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.

A seat post for a bicycle comprises a post body having a first end shaped to be connected to a bicycle frame, a second end shaped to be connected to a saddle, at least two longitudinal portions meshing with each other and slidable relative to one another along a longitudinal extension, and a fixing apparatus by which the two longitudinal portions can be fixed to one another in a settable relative position, the fixing apparatus being influenced to selectively fix and unfix by a radio signal.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.

A control device is provided for controlling an adjusting device of a human-powered vehicle. The adjusting device adjusts a front initial sag amount of a front suspension of the human-powered vehicle in a state in where a rider is riding the human-powered vehicle and a rear initial sag amount of a rear suspension of the human-powered vehicle in a state where the rider is riding the human-powered vehicle. The control device comprises an electronic controller configured to output a front control signal that adjusts the front initial sag amount of the front suspension of the human-powered vehicle, and output a rear control signal that adjusts the rear initial sag amount of the rear suspension of the human-powered vehicle to the adjusting device based on traveling information related to traveling of the human-powered vehicle.

A motorcycle braking arrangement comprising a brake lever (and/or brake pedal) defining a grasping or stepping surface, respectively, whereby a rider is able to apply pressure in order to produce a first analogue signal, a force-sensitive resistor (FSR) mounted on and/or in the surface and configured to produce a second analogue signal. In this manner, pressure applied to the grasping surface results in simultaneous production of the first and second signals, whereby a controller is configured to electronically correlate the second signal with the first. The arrangement also includes at least one servomechanism, which is arranged in signal communication with the controller and is configured to actuate a brake of the motorcycle according to the correlation between the first and second signals.
