PROBLEM TO BE SOLVED: To solve problems that regenerative power is small, and the reduction effect of the capacity of a power source is small in an power-assisted bicycle having a driving part on a transmission mechanism behind a one-way clutch. SOLUTION: An outer rotor type permanent magnet synchronous motor is used for a drive motor, a switching element to be ON-OFF controlled to supply the regenerative power to a battery is provided between the battery and a forward/reverse switchable drive device, and a diode is connected to this switching element in a reverse parallel manner.
