ABSTRACT:
A three stage, sixteen-speed, planetary driving wheel, with the pedal drive shaft on the axis of the wheel and vehicle interface fittings on both sides inboard of the pedal crank arms, for mounting in pedal powered vehicles to replace the chain and derailleur system used in conventional multiple speed bicycles. Because the planetary gear arrangement is completely enclosed inside the wheel hub where it is well protected from dirt, and because this driving wheel provides five low range speeds below direct drive, it is well suited for mountain bicycles or for transporting the payload of a bicycle camper up steep grades.
