摘要： A bicycle drive system includes a bicycle drive unit and a bicycle battery unit. A first power supply path supplies power from the battery unit to the drive unit. A second power supply path supplies smaller power from the battery unit to the drive unit than the first power supply path. In a case where the drive unit and the battery unit are connected by the first power supply path and the second power supply path, the bicycle drive system is configured to be switched between a first state, in which the battery unit stops supplying power to the drive unit via the first power supply path and supplies power to the drive unit via the second power supply path, and a second state, in which the battery unit supplies power to the drive unit via at least the first power supply path.

摘要： A bicycle drive unit includes a motor, a second electronic controller and a communication circuit. The motor is configured to assist in propulsion of a bicycle. The second electronic controller controls the motor. The communication circuit is configured to communicate with an operation device that operates a bicycle electric component. The second electronic controller is operable in a third state, in which the motor is drivable, and a fourth state, which consumes less power than the third state and does not drive the motor. The second electronic controller is configured to switch an operation state from the fourth state to the third state upon the communication circuit receiving an input signal while the second electronic controller is operated in the fourth state.

摘要： A bicycle power supply system is configured to be connectable to a plurality of battery units and configured to switch each of the plurality of battery units between a first state and a second state. The bicycle power supply system includes a memory device and an electronic controller. The memory device stores order information for switching the plurality of battery units from one of the first state and the second state to the other one of the first state and the second state in a predetermined order. The electronic controller switches the plurality of battery units from one of the first state and the second state to the other one of the first state and the second state in accordance with the order information in a case where the plurality of battery units is connected. The memory device is configured to changeably store the order information.
