ABSTRACT:
A rider actuated amusement device comprises a base which at one end includes a transverse crossbar supported on swivel casters. A shaft which is downwardly inclined toward the opposite end of the base is axially secured but rotatably free in a bearing of the base. A circular disc is fixed on the lower end of the shaft, the disc and swivel casters forming a three point support for the device. A transverse handlebar extends through the upper end of the shaft. A mounting member fixedly secured to the shaft between the handlebar and base bearing has a seat on the upper portion close to the shaft and a downwardly dependent portion extending below the shaft and having a foot rest bar for the rider's feet, whereby the rider shifting his weight to either side causes the disc to roll a short distance and the casters to move so that the location of the device with respect to the ground or supporting surface changes.
