The U3-X is an experimental personal mobility device concept by Honda, that can provide free movement to the rider in all directions, backward, forward, side-to-side and transversely by implementing Honda’s balance control technology and latest omni-directional driving wheel system. The users will be able to adjust speed, moving directions and stop anyhow they want by leaning their upper body. The one-wheel-drive compact mobility device allows the rider to seat at just around the same eye level as he or she is standing on the gourd and let them easily land on the ground from the footrest. The device remains in an upright position by implementing the precise control technology, which allows for agile and smooth movements and straightforward operation.
