<p>A driving mechanism for a bicycle, for example, using a conventional chain drive comprises an arcuate body 1 pivoted for oscillating movement on a base 8 connected to the bicycle frame. A foot rest 5 is attached or integral with the body. A connecting rod 6 connects one end of the arcuate body to the crank 9 of a chain wheel 10 of the bicycle to convert oscillatory motion of the body into rotation of the chain wheel to drive the bicycle. The arcuate body can be oscillated by a rider without bending of the knee. <IMAGE></p> |
