Abstract

The jumping bicycle includes frame, handlebar, front wheel, back wheel and saddle, as well as two characterized pedals and two cranks. The two cranks are hinged through the middle shaft to the frame and can move within certain range limited with the limiting block to drive the bicycle forwards via chain or flexible rope and two flywheels driving the back wheel. The jumping bicycle has high transmission efficiency and light and flexible riding, and may be used in replacing walking and for building body.
