ABSTRACT:
A power transmission unit for coupling a prime mover to a vehicle, in particular a bicycle. The unit has a clutch assembly, a gear train, and a freewheel mechanism. The output shaft of the prime mover is connected to the input side of the clutch assembly. The output of the clutch assembly is connected to the input side of the gear train. The output side of the gear train is connected to the freewheel mechanism. The freewheel mechanism is connected to a first sprocket wheel. The first sprocket wheel and a second sprocket wheel are mounted together on a common freewheel which in turn is mounted on the crankshaft of the bicycle. The second sprocket wheel is connected to the rear wheel of the bicycle. In the absence of power from the prime mover, the bicycle may be used in a conventional manner. When in use, the prime mover drives the rear wheel of the bicycle via the clutch assembly, gear train, freewheel mechanism, sprocket wheels and the rear wheel.
