Abstract: A power module of an electric assisted bicycle is disclosed and includes a pedal shaft, a gear-plate-output shaft, a reducer, a motor, a first sensor, a housing, a second sensor and a driving controller. The gear-plate-output, a reducer-output shaft and a reducer-fixed shaft of the reducer are disposed in parallel and sleeved on the pedal shaft concentrically. The motor drives the gear-plate-output shaft to rotate. The first sensor is disposed on the reducer-fixed shaft for sensing a first torque of the reducer-output shaft acting on the reducer-fixed shaft. The reducer-fixed shaft is connected to the housing. A frameset-fastening component protrudes outwardly from the housing, and is configured to fix the power module on the frameset. The second sensor is disposed on the frameset-fastening component for sensing a second torque of the power module acting on the frameset. The driving controller controls the motor in accordance with the second torque and the first torque.
