A vehicle which can be driven by waist-twisting of human body is disclosed. The vehicle is, like a scooter, but it has a round footboard. Player stands on this round footboard with his two, hands gripping the handlebar and they twists his waist with his heels and toes tilting to force, each point of circumference of the footboard to ground on the resisting board in turn. In this, way, the player's strength of waist-twisting causes circular motion. The circular motion is, transmitted to the two driven wheels by a pair of bevel gears and the horizontal axle. Therefore, the player's strength of waist-twisting causes the steerable vehicle runs.

- Filed August 6, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 6, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
