Abstract
A motorized bicycle includes an electric motor, a motor current detector, a pedaling force detector and a controller. The controller compares the range of fluctuation in a pedaling force detected by the pedaling force detector with a predetermined range value, and stops the driving of the electric motor if the fluctuation range of the pedaling force is kept smaller than the predetermined range value for more than a predetermined time period.
