The vehicle transports a person sitting or standing for many miles and is usable in all pedestrian areas. It will climb a 1:4 gradient and can tow a trailer. The multi-directional drive/steering unit 11/12 is rotatable through 360 DEG giving immediate motion in any horizontal direction. A stabilising system, which may comprise a pivot 14 with fore-and-aft axis to enable the handlebars to lean, greatly reduces the likelihood of the rider and vehicle becoming unstable while traversing lateral slopes. The vehicle has simple fold-away features with no separation of parts and is light enough to be carried upstairs, lifted into a car, bus or aircraft or pulled along on its rear wheels. It can be stood on-end for space saving. The self-contained drive/steering unit can be attached, via a simple bracket, to other lightweight unpowered mobile devices to give similar powered and steering features or be a powered unicycle. These general features can be packaged in several forms. <IMAGE> |
