A pedal-assisted bicycle includes a frame, a traction system with a battery, a central motor, a hub motor and a control unit. The central motor is directly connected to the pedal assembly to provide torque to the pedal assembly and is powered by the battery, while the hub motor is arranged at the hub and is powered by the battery. The control unit receives first input signals of an operating condition selectively variable between a servo operating condition and a charging operating condition and to detect the operating condition as a function of the first input signals and, in the servo operating condition, to emit a driving signal to drive the hub motor and the central motor following a maximum efficiency curve obtained from an envelope of the efficiency curves of the hub motor and the electric motor as a function of the linear speed (Vbike) and the transmission ratio.
