Patent ID: 6874592

Claim:
An electrically assisted bicycle comprising: front and rear wheels; a human power drive mechanism for transmitting human power from a pedal to the rear wheel; a battery-powered motor; a motor drive mechanism for auxiliary driving one of the front and rear wheels by the motor, wherein the one wheel constitutes an auxiliary-driven wheel and the other wheel constitutes a non-auxiliary driven wheel; a brake lever operated by a driver; a human power brake mechanism operably coupled to the brake lever for braking the non-auxiliary driven wheel by human power transmitted from the brake lever; and a motor control circuit operably connected to the brake lever for controlling the motor so that the motor is regeneratively braked to act as a power generator, wherein the auxiliary driven wheel is regeneratively braked by the motor and the non-auxiliary driven wheel is not braked by the human power brake mechanism when a displacement amount of the brake lever is less than or equal to a predetermined amount, and wherein the auxiliary driven wheel is regeneratively braked by the motor and the non-auxiliary driven wheel is braked by the human power brake mechanism when the displacement amount of the brake lever is greater than the predetermined amount.
