A power module (1) of an electric assisted bicycle is disclosed and includes a pedal shaft (10), a gear-plate-output shaft (20), a reducer-output shaft (51) and a motor-output shaft (61). The pedal shaft (10) is arranged along an axial direction (C). The gear-plate-output shaft (20) includes a first section (21) and a second section (22) arranged in the axial direction (C). The first section (21) is concentrically sleeved on the pedal shaft (10) through a first one-way bearing (30a) along a radial direction. When the pedal shaft (10) is forced to rotate, the gear-plate-output shaft (20) is driven through the first one-way bearing (30a). The reducer-output shaft (51) is concentrically sleeved on an outer surface of the second section (22) through a second one-way bearing (30b) along the radial direction. The motor-output shaft (61) is concentrically sleeved on the reducer-output shaft (51) along the radial direction. When the motor-output shaft (61) drives the reducer-output shaft (51) to rotate, the gear-plate-output shaft (20) is driven by the reducer-output shaft (51) through the second one-way bearing (30b).
