The present invention is structured by using one or both of an active wheel (113) and a passive wheel (413) being composed of an eccentric transmission wheel and being combined with a synchronous transmission belt (100) for forming an eccentric wheel transmission wheel series, so that in the reciprocal treadle performed by the human's feet, when the feet input forces at different angles from the treadle shafts (103,203) of the treadles (102,202) to an active wheel shaft (111) combined on the active wheel (113) through cranks (101,102), the active wheel (113) forms different transmission speed ratios relative to the passive wheel (413) according to the treadle angle.
