ABSTRACT:
A bicycle can have jumping capabilities by providing a spring-biased auxiliary frame directly below the primary frame, and mounting the drive sprocket on the auxiliary frame. The person riding the bicycle can transfer his weight from the bicycle seat to the foot pedals on the drive sprocket so as to lower the auxiliary frame. When the person shifts his weight back onto the seat the auxiliary frame is rapidly raised by the mounting springs, such that the auxiliary frame forcibly strikes the main frame to lift the bicycle from the ground surface.
