Abstract

The vehicle has a three wheel, triangular wheelbase and a pyramid-shaped frame formed of four tubular side members and an inclined tubular steering fork supported rotatively by the side members adjacent its upper and lower ends. Handle bars located generally above the rear wheels rotate the steering fork to turn a front wheel located adjacent the front corner of the frame for steering the vehicle. Two spaced apart rear wheels are mounted for rotation about a common axis adjacent the rear corners of the frame. A platform for supporting a rider is mounted by the frame between the rear wheels, and forms a support surface so constructed and arranged with respect to the handle bars and rear wheels that the vehicle may be tilted onto two of its three wheels at a time, and then may be balanced in that position so as to perform a 'wheelie' or similar maneuver, merely by concentrating or shifting the weight of the rider on the support surface and applying fore, aft or lateral balancing forces to the handle bars.
