To provide a bicycle drive mechanism that has a function capable of recycling accumulated energy using same-pole repulsive force between magnet plates and effectively utilizing compressive force of a spring.SOLUTION: Two kinds of cylinder shaft are constituted in a bicycle bottom bracket shell 1 to install a hollow cylinder shaft 3 and a center cylinder shaft 5, and the shafts have a plurality of interlocking connection components built so as to serve as free rotation devices individually, thereby improving great effects on function improvements. As a pedal crank, a lower disk type pedal crank 7 is employed to let stepping-in power effectively interlock with reduction in power through principle operation of a lever. For a condition of effective accumulation of energy (power), a power ratio to energy in rotation (wheel half rotation) for stepping down of the lower disk type pedal crank from above to below essentially needs to be small (lower).SELECTED DRAWING: Figure 2

    【課題】マグネット板の同極反発力利用及びスプリングの圧縮力を有効活用した蓄積エネルギーを再利用出来る機能を持った、自転車駆動機構を提供する。【解決手段】自転車ボトムブラケツトシェル1内にシリンダーシャフトを2種類構成し、中空シリンダーシャフト3,中心シリンダーシャフト5、を設置し、シャフトは個別に自由回転装置とするため.複数の連動接続部品を組み込むことで機能改善が飛躍的な効果が向上する。ペタルクランクを下部円板型ペタルクランク7にする事で踏み込む動力はテコの原理作用が働き動力の軽減と有効に連動する。エネルギー(動力)を有効に蓄積する条件は下部円板型ペタルクランクの上部から下部へ踏み込む(車輪半回転)回転時のエネルギーに対して動力比率は少なく(低く)することが必要条件になる。【選択図】図2
