<p>PROBLEM TO BE SOLVED: To provide a cycle with a leverage mechanism in which leverage bars are attached to a crank and a pedal part, respectively so that a user can travel by the cycle lightly and easily.SOLUTION: One end 1 of the leverage bar is coupled to a bar 4 attached from a top part of a cycle body in a state that the bar 4 moves in a lateral direction and does not move in a vertical direction, and to the other end 2 of the leverage bar, a pedal is attached for fixing the leverage bar in a state that one end 1 serves as a base point. An intermediate part 3 of the leverage bar is attached to a tip end of a crank of the cycle, and when a user pedals the pedal, large force is transmitted to the tip end of the crank with the ends of the leverage bar as base points. Thereby the user can travel by the cycle fast and lightly using the leverage.</p> |
