Abstract
An electric motor speed controller for use in a bicycle includes a motor to provide a propulsion force to move the bicycle. The actual motor speed and a target motor speed are compared, and if the actual motor speed is lower, more current is supplied to the motor, and if the actual motor speed is higher, less current is supplied to the motor.
