The invention provides an integrated dual-drive assembly of an electric power-assisted bicycle and a mounting method thereof. The dual-drive assembly comprises a base, a drive shaft, a chain wheel assembly, an electric motor, a gear transmission assembly and an auxiliary gear. The chain wheel assembly is connected with the driving shaft through a one-way clutch, and the driving shaft is provided with two pedals through two crank connecting rods to transmit a pedal force to the driving wheel. An output shaft of the electric motor is connected with the gear transmission assembly, the gear transmission assembly is meshed with the auxiliary gear, the auxiliary gear is connected with the chain wheel assembly through a connecting mechanism, and the chain wheel assembly is connected with the driving shaft through the one-way clutch to transmit power of the electric motor to the driving shaft. The driving shaft is installed in a shaft sleeve, and two bearings are arranged in the shaft sleeve and used for driving the driving shaft to work when the power-assisted bicycle advances through pedaling force and power of the electric motor. And the shaft sleeve and the base are integrally formed.The assembly is compact in overall structure, small in size, high in mounting efficiency and high in applicability; and the dual-drive function is realized.
