The invention discloses an integrated power-assisted middle motor which comprises a motor module, a speed reducer module, a clutch module, a controller module, a pedaling frequency signal sensor, a motor shell, a motor gear shaft and an output middle shaft, the motor shell comprises a left side cover, a right side cover, a motor box body and a controller outer cover, and the motor box body comprises a middle partition plate, a first left side wall and a second right side wall. The two ends of the output middle shaft are connected with pedal cranks, a motor in the motor module is an outer rotor motor, and the first cavity and the second cavity are filled with cooling liquid. In order to increase the power provided by the electric power-assisted bicycle, the outer rotor is used in the design, so that the motor module can realize larger torque output. The pedal frequency signal sensor is arranged on the output middle shaft connected with the pedal crank, the controller module controls power output of the motor module according to the power assisting signals, and power assisting can be better provided for a user through the design. The cooling liquid is used for preventing the motor module from being damaged due to overheating in the operation process.
