Abstract: A motor bicycle control system is provided for controlling a motor for assisting rotation of a bicycle wheel. The bicycle motor control system includes a motor communication part and a first mode switching part. The motor communication part performs power line communication with an electrical bicycle component and that changes a motor operation mode of the motor. The first mode switching part is operated either by electrical power supplied via a power line through which the motor communication part performs power line communication, or by electrical power obtained from a generator. The first mode switching part switches the motor operation mode from a motor driving mode in which the motor assist in rotating the bicycle wheel to a motor power generating mode in which the motor outputs electrical power that has been generated using rotation of the bicycle wheel according to a state of communication with the electrical component.

Abstract: An auxiliary bicycle power supply system is provided that basically includes a bicycle power generating portion and an auxiliary power supply portion. The auxiliary power supply portion operates by power from the bicycle power generating portion. The auxiliary power supply portion is configured to supply power generated by the bicycle power generating portion to an electrical bicycle component based on a power supply situation from a main bicycle power supply.

Abstract: A bicycle regenerative brake control device is provided for controlling a motor, in relation to a brake mechanism that can be mounted on an electric bicycle in which human-powered driving is assisted by the motor. The bicycle regenerative brake control device basically includes a first control part, a second control part and a switch control part. The first control part controls the motor so as to generate a uniform first regenerative braking force. The second control part controls the motor so as to generate a gradually increasing second regenerative braking force upon determining the brake mechanism shifts from an initial state to a braking state. The switch control part switches to a control performed by the second control part in response to the brake mechanism shifting from the initial state to the braking state while control is being performed by the first control part.
