Abstract: An assistance control system includes a sensor mounted on a cycle body of a cycle, and a controller communicable with the sensor and an assistance module of the cycle. The sensor senses operation of the cycle body so as to output a sense signal indicative of a state of usage of the cycle body. Based on the sense signal, the controller switches between a boost mode and a deboost mode. In the boost mode, the controller outputs a control signal to the assistance module so as to control the assistance module to increase assistive torque for driving movement of the cycle body. In the deboost mode, the controller outputs the control signal to the assistance module so as to control the assistance module to decrease the assistive torque.
