PROBLEM TO BE SOLVED: To solve problems that losses in a reduction gear mechanism of a power-assisted bicycle are increased, and a battery capacity is increased for long distance traveling because a battery cannot be regenerated. SOLUTION: A power source is miniaturized, and the service life of the power source is prolonged by providing the power source of an electric double layer capacitor. A reduction gear mechanism is omitted by providing a drive motor of a outer rotor type permanent magnet synchronous motor, enabling regenerative braking.
