LEVER TYPE POWER TRANSMISSION DEVICE OF BICYCLE AND POWER MACHINE WITH MAGNETIC ACTION USED FOR THE DEVICE

摘要

A lever type power transmission device of a bicycle, wherein a large force can be developed with a small force by the power point and application point of a lever by the principle of a lever, the positive magnetic poles of magnets generate a magnetic force, and these two actions are combined with each other, wherein the device is installed on a frame of the bicycle so as to be interlocked to forward and backward wheel gears, whereby a bicycle pedal working pressure can be reduced and stable propelling of the bicycle can be persistently performed so as to reduce fatigue.
