Abstract
A pedal-electric bicycle utilizes an e-clutch to prevent a motor of the pedal-electric bicycle that is fixedly engaged to a drivetrain of the pedal-electric bicycle from resisting movement of the drivetrain when the motor is not transferring power to the drivetrain. The e-clutch causes the motor to operate at a minimum torque level to overcome the internal resistance thereof. The use of an e-clutch beneficially permits the elimination of a mechanical motor clutch, thus reducing complexity, cost, and weight of the pedal-electric bicycle.
