Abstract
A torque sensor for electrically assisting a vehicle with pedals includes a housing, a rotating member, an actuator, and an resistor. The housing defines a receiving chamber and is configured to be coupled to the driving member. The rotating member is rotatably mounted in the receiving chamber and configured to rotate under an external force. The resistor is received in the receiving chamber and the actuator slides along the electrical resistance and compresses a spring as a rider applies force to the pedals. The variable resistor is coupled to a controlling module which governs the assisting power. The disclosure also includes an electric bicycle using the torque sensor.
