  • the reduction in the direct displacement that may occur due to the large difference in distance between the pedal and the force point at which the occupant exerts force and the pulley and force point at which the force advances the bicycle by the force is arranged laterally. It can be compensated by an increase in displacement in the power transmission unit, such as at least one pulley and a wire surrounding the fixed drum, thereby enabling high-speed driving while minimizing the loss of the pedaling force of the cyclist.
  • the left and right pedals are alternately lifted by forward rotation and reverse rotation of the rotating shaft, so that the occupant can apply external force continuously, and the reverse rotation of the rotating shaft is used not only to raise the pedal but also to the reverse gear.
  • the forward drive by it can be applied to a bicycle that can implement the forward drive while minimizing the power lost to the outside.
