ABSTRACT:
A thirteen-speed driving wheel which includes a pedal drive shaft on the axis of the wheel, pedal crank arms, and vehicle interface fittings on both sides for mounting in pedal powered vehicles to replace the chain and derailleur system used in conventional bicycles. The driving wheel is particularly well suited for use in front wheel drive recumbent bicycles and tricycles and, because the driving gears are all enclosed within the wheel hub, provides a compact, low maintenance alternative to conventional chain drives.
