ABSTRACT:
A bar-riding wheel positioned on a single circular cross-sectional bar. One end of the bar is partly restrained but allows for a limited amount of swinging and/or rotating motions. The other end of the bar is held by the operator's hand, by means of a handle, and provides its actuating motion to the wheel by lifting the handle. The bar cross-section generally increases from its free end to its partly restrained end. The riding wheel exhibits a deeply shaped groove such that as the wheel rolls in the direction of the increasing cross section of the bar, the center of gravity of the wheel eventually rises, up to and beyond a point where the wheel riding position becomes unstable. A mobile counterweight system causes the instantaneous center of gravity of the riding wheel to be located below its instantaneous axis of rotation at all times. The object of the operation is to successfully manipulate the bar such that the riding wheel rolls as far as possible, in the unstable region without toppling over. The farther the wheel rolls along the unstable region, the greater the skill of the operator. Indicia on the bar provides an accurate measurement of the operator's skill.
