Abstract
A central wheel structure transportation device with fore-aft auto-balancing. The auto-balancing is selectively enabled (and disabled) to improve rider experience, safety and ease of mounting and use. In one embodiment, during mounting, auto-balancing is not enabled until the lateral tilt angle of the device is below a given threshold from vertical. Fore-aft sensors, lateral tilt sensors, foot presence sensors, and/or accelerometers, or the like, may be used in various combinations to affect device operation and performance.
