ABSTRACT:
A power-assisted velocipede can be propelled selectively or concurrently by pedal power and by a battery-operated power unit. The velocipede includes a pedal crank which is mechanically coupled to the rear wheel by way of a sprocket incorporating an overrunning clutch and the power unit is mechanically coupled to the rear wheel by way of a second sprocket also incorporating a one-way clutch, both clutches operating so as to permit the rear wheel to overrun in the forward direction. The power unit is mounted to the frame and to the rear wheel axle and incorporates a small DC motor and a speed-reducing gear chain, the first gear being coupled to the motor and the last gear being rotatively coupled to the second sprocket by interfitting with the face of the last gear. The power unit is small, compact and easy to install on a more or less standard velocipede.
