PROBLEM TO BE SOLVED: To solve a problem that, in a conventional cycle, large power is needed to advance at a slope or bad road, especially, for women, children, and a person who has weak body force, and such a situation is inconvenient.SOLUTION: A front gear 4 is attached to left and right sides via a frame, a shaft 7 is bent forward at a link 2, and it is possible to step on at a time point of a top dead center for weighting. In addition, because the link 2 and the front gear 4 are coupled separated from a center part, by the principle of the lever, by the same motion, larger propulsion power can be generated.

    【課題】従来の自転車では、坂道、悪路等で、進むためには大きな力を必要としていた。特に女性、子供、等その他体力の弱い者にはそのような状況では不便で問題があった。【解決手段】フロントギア4をフレームを介して左右に取付して、シャフト7をリンク2で前方に曲げ、上死点の時点でも踏み込こんで加重出来るよう変更した。又、中心部より離してリンク2でフロントギア4と連結したことで、てこの原理で同じ運動でより大きな推進力を生む事が出来るようになった。【選択図】図1
