Abstract: A coaxially located crankshaft and wheel utilize a second radially spaced shaft to transmit power from the crankshaft back to the wheel. Multiple gears may be shifted between. In one embodiment, the wheel is a front wheel of a bicycle. The crankshaft includes pedals, and a first sprocket for transmitting pedal power to a first drive chain. The first drive chain couples to a second sprocket on a second shaft, which transmits power to a second drive chain via a third sprocket or set of sprockets on the second shaft. A second chain couples the third set of sprockets to a fourth set of sprockets, coaxially located with the wheel and crankshaft.
