Abstract
A pivotal jumping stick with the handlebars and footrest connected together and pivoted at their centers to permit the user to maintain his balance on uneven terrain. While in motion, a pin slides vertically in a slot formed in the impacting rod, counteracting the inherent twisting force of the spring mechanism, and allowing the user to accurately steer the device.
