A regenerative braking energy dissipater system which is adapted to dissipate energy from a regenerative brake in the case when the battery cannot accept further energy. The system may switch the energy flow from the battery to a dissipater when the battery has reached a high level of charge. The dissipater may include load resistors. The system may be designed such that the airflow around the dissipater flows over and under the dissipating plate.

Provided is a shifting device for shifting of a bicycle gear, such as a hub gear, of a bicycle. The shifting device includes a main control unit and preferably a motor control unit. The device includes a shifting control unit for receiving shifting instructions from the main control unit or the motor control unit. The shifting control unit includes a processing unit and a memory, power receiving means, such as including an electrical connector, for receiving power from a battery of the main control unit and/or a drive motor battery of the bicycle, a shifting motor, such as an electric motor, such as a stepper motor for providing a shifting motion for driving a shifting assembly for actuating a gear actuator, the shifting assembly for transferring the shifting motion from the shifting motor to the gear actuator, and the gear actuator for transferring the shifting motion to the bicycle gear. The shifting control unit, by means of communication with and controlling by the main control unit of the bicycle, is configured as a subsystem of the bicycle. The shifting control unit shifts the bicycle gear at each time on the basis of shifting instructions from the main control unit or the motor control unit.

A control device is provided for a human-powered vehicle that includes a generator configured to output electrical power, an electric power storage device electrically connected to the generator, and a component having an actuator actuated by electrical power from at least one of the generator and the electric power storage device. The control device includes a controller electrically connected to at least one of the generator and the electric power storage device. The controller is configured to control an operation state of the component in accordance with information relating to at least one of an output state of the generator and a store state of the electric power storage device.

A self-powered motorcycle or bicycle includes: a pair of shock absorber frame housings (101), each having a cylindrical hollow inside, a closed upper end portion, a split space formed at a lower end portion, rack gear moving holes (101a) respectively formed in both sides of the outer wall in a longitudinal direction, and self-powered generators (100) respectively mounted on both sides of the outer wall, the pair of shock absorber frame housings being mounted to face each other; a pair of shock absorber frames (102); disc-shaped partitions (102c) fixed in a horizontal direction; anti-rotation protrusions (104a) formed at both sides of the spring guide in a longitudinal direction; and anti-rotation protrusion guide holes (102b) formed at both sides of the shock absorber frame.
