ABSTRACT:
An electric-powered bicycle has a monitoring unit connected to a throttle detector, a bicycle torque detector and a bicycle speed detector so as to monitor the position of a twist grip throttle, the bicycle torque on a pedaling device, and the forward moving speed of the bicycle. The monitoring unit is further connected to a motor driver, and controls the motor driver to deactivate an electric driving motor when the twist grip throttle is in the non-operative position and the bicycle torque on the pedaling device is not over a preset limit while an electric power source for the electric driving motor is activated, and when the twist grip throttle is in the operative position, the bicycle torque is not over the present limit and the forward moving speed of the bicycle is not over a preset safety speed while the electric power source is activated, thereby resulting in enhanced user safety.
