A powered, gyroscopically balanced unicycle device to be used while standing, having leg contact surfaces which are made of a yielding, slightly soft material whose mild friction against the user's legs allows stable, precise control of the device without restraining the legs in any way. In one embodiment a single hubless wheel is driven by a friction drive mechanism which transmits torque from a motor through a drive wheel positioned below the foot platforms and in contact with the inner rim of the wheel. Various structures are provided for supporting the wheel and keeping it in place as it spins; absorbing small vertical movements of the wheel to prevent them from being transmitted to the foot platforms; enabling folding of the foot platforms; and facilitating carrying of the device by hand. Other embodiments are described and shown.

A controller coupled to the drive governs the operation of the drive at least in response to the position of the center of gravity of the vehicle to dynamically control balancing of the vehicle.

A controller for providing user input of a desired direction of motion or orientation for a transporter. The controller has an input for receiving specification by a user of a value based on a detected body orientation of the user. User-specified input may be conveyed by the user using any of a large variety of input modalities, including: ultrasonic body position sensing; foot force sensing; handlebar lean; active handlebar; mechanical sensing of body position; and linear slide directional input. An apparatus that may include an active handlebar is provided for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle.
