The present invention is structured by using one or both of an active wheel and a passive wheel being composed of an eccentric transmission wheel and being combined with a synchronous transmission belt 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 of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle.
La présente invention est structurée au moyen dune roue active ou dune roue passive, ou des deux, celles-ci étant composées dune roue de transmission excentrée et combinées à une courroie de transmission synchrone pour former une série de roues de transmission à roue excentrée. Ainsi, dans la pédale à va-et-vient actionnée par des pieds humains, lorsque les pieds transmettent des forces à différents angles par rapport aux arbres des pédales à un arbre de roue active combiné sur la roue active par lintermédiaire de manivelles, la roue active forme des rapports de vitesse de transmission différents par rapport à la roue passive selon langle de la pédale.
