Abstract
Abstract A one-wheel vehicle having an outer hoop, an inner carriage movably mounted inside said outer hoop, engine means for driving said inner carriage in a counterclockwise direction upon said outer hoop to impart forward movement of the vehicle, steering means comprising a seat supporting the occupant in a semireclining position movably suspended from said inner carriage and being pivotal in a direction transverse to the movement of said vehicle and means for swinging said seat in a pendulum-like movement. In a further aspect hereof, said outer hoop comprises a cylinder having a truncated cone attached to each end thereof thereby defining three stable rest positions for said vehicle. In a still further aspect hereof, said outer hoop comprises two separate hoops spaced apart having an outer band extending threrearound wider than the space between said two hoops and being fastened to each, said spacing providing a track guiding said inner carriage upon said band.
