The invention discloses a built-in-motor electric-bicycle middle axle force moment sensing system. The built-in-motor electric-bicycle middle axle force moment sensing system comprises a motor, a middle axle, a strain sleeve, a torque sensor, a bidirectional overrun clutch, a chain wheel support and a five-way part. The middle axle is sleeved with the strain sleeve, one end of the strain sleeve is fixed to the five-part part and connected with the bidirectional overrun clutch, the other end of the strain sleeve is fixedly connected with the middle axle, and the inner surface of the strain sleeve is attached to the outer surface of the middle axle. The torque sensor is pasted to the outer surface of the strain sleeve and transmits a signal to a controller, and the controller controls the motor to carry out outputting. The bidirectional overrun clutch is divided into an inner ring, a middle ring and an outer ring, the middle ring is fixedly connected with the chain wheel support, the inner ring is connected with the restrain sleeve, and the outer ring is connected with an output part of the motor. According to the built-in-motor electric-bicycle middle axle force moment sensing system, the strain sleeve serves as a link of the treading force transmission middle axle and the bidirectional overrun clutch, currently-common unbalanced left-and-right foot detection generated during measurement of a force moment sensing system is avoided, the riding smooth feeling is guaranteed accordingly, and the riding comfort level is improved.
