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 a crank connecting rod 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, and the chain wheel assembly is connected with the driving shaft through the one-way clutch and transmits power of the electric motor to the driving shaft. A first bearing is installed in the first shaft sleeve, a second bearing is installed in the second shaft sleeve, and the first bearing and the second bearing are matched with the driving shaft and used for driving the driving shaft to work when the power-assisted bicycle advances through pedaling force and power of the electric motor. The dual-drive assembly is compact in overall structure, small in size, high in mounting efficiency and high in applicability; and the dual-drive function is realized.
