Provided are a user verifying bicycle control system and a user verification method thereof, including a sensing module and a control module installed on a bicycle. The sensing module obtains a torque signal and an angle signal from a crank sensing component, further obtains a speed signal from a speed sensing unit, and outputs the torque signal, the angle signal, and the speed signal to the control module; the control module assembles the torque signal, the angle signal, and the speed signal into a signal sequence as a key to verify a user identity for the bicycle.
