Abstract
A skateboard comprises a single oversized centrally-located wheel in addition to conventional pairs of front and rear wheels. The wheels are arranged so that the board will ride on no more than three wheels at a time, with either the front or rear pair being elevated above the supporting ground surface, depending upon the rider's longitudinal weight distribution on the skateboard relative to the center wheel. An optional foot-operated friction brake is engageable with the center wheel.
