| Abstract: |
This disclosure pertains to a one wheeled vehicle rotatably affixed to a yoke. One arm of the yoke is provided with a stationary foot rest. The other arm of the yoke contains a rack which when reciprocated operates a gear train causing the wheel to rotate. A platform is secured to the uppermost portions of the rack and is biased upwardly by a spring urging the rack in an uppermost position. A pole extends upwardly from the yoke providing steering control to the apparatus and a balancing aid to the user thereof.
