Abstract
An elebike comprises a bicycle frame, at least one wheel, a transmission mechanism installed for actuating the wheel, a pedal mechanism for transforming pedal forces into pedal torque and coupling the torque to the transmission mechanism to actuate the wheel, a servo motor comprising a control port used to generate a torque according to an input voltage inputted from the control port, a coupling device for coupling the servo motor torque to the transmission mechanism to actuate the wheel, and a power control handle for outputting a handle voltage according to the rider's inputs to control the torque outputted by the servo motor. The bicycle control system comprises a torque detector for detecting the pedal torque inputted by the rider and outputting a torque signal, a rotation rate detector for detecting the rotation rate of the wheel and outputting a rotation rate signal, a control circuit for processing the torque signal outputted by the torque detector and the rotation rate signal outputted by the rotation rate detector and outputting a motor control voltage, and a voltage coupling device for coupling the handle voltage outputted from the handle with the motor control voltage ou…
