<p>A bicycle and a motorcycle with a novel power transmission mechanism on a conventional drive wheel, capable of reducing a drive energy to a half or less and capable of being utilized for saving the energy of bicycles, motorcycles, and tricycles, wherein, in a conventional bicycle, a ring chain (21) is fixed to a ring chain holding ring (21b) installed on a rear wheel concentrically with an axle through a quarter-split ring (21c), a sprocket (77) is engaged with the ring chain (21) at the inner uppermost part of the chain, a sprocket (8) and the sprocket (77) connect respectively integrated sprocket (72) the sprocket (76) through a chain (8) for interlocked moving the sprockets (77, 76) are allowed to be rotated on a shaft (23) of a frame (20f) and the sprockets (8, 72) are allowed to be rotated on the axle (7), whereby, in a motorcycle, merely 1/2 to 1/3 of energy is required to travel over the same distance at the same speed, and a remarkable energy saving can be achieved and, in a bicycle, the bicycle can run on a slope in the same manner as on a level ground.</p> |
