Abstract
A torque sensor for electrically assisting a vehicle with pedals includes a housing, a first gear, an actuator, and a control circuit. The housing defines a receiving chamber and is configured to be coupled to a drive member. The first gear is rotatably mounted in the receiving chamber. The actuator is received in the receiving chamber and is driven by the first gear. The control circuit including a resistor is received in the receiving chamber and the actuator slides along the resistor as a rider applies force to the pedals, thus for adjusting a resistance value of the control circuit, to allow the control circuit to output a signal which governs the assisting power. The disclosure also includes an electric bicycle using the torque sensor.
