An electric bicycle is described with a propulsion unit comprising two pedals (12), an electric motor (M) to assist pedaling, a first drive toothed wheel (22) connected via a free wheel to the pedals, and a second drive toothed wheel (24) which is coaxial to the first toothed wheel and connected to the motor to receive drive torque, Two chains transfer drive torque from the first and second wheels to two gears of a bicycle wheel. An electronic circuit controls electrical power generated by the electric motor, and preferably stores it in a battery.
