Abstract
An electrically assisted bicycle includes a human power drive mechanism for transmitting human power from a pedal to a rear wheel, a motor drive mechanism for auxiliarily driving a front wheel or the rear wheel by a motor, a battery for supplying the motor with electric power, a brake lever operated by a driver, a brake mechanism for braking the front or rear wheel that is not driven by the motor drive mechanism, by human power transmitted from the brake lever, and a motor control circuit for controlling the motor so that the motor is regeneratively braked to act as a power generator when the brake lever is operated.
