Personal mobility vehicles with adjustable wheel positions

Abstract

An adjustable wheel mobility vehicle can have a support structure for supporting a rider, a modular conveying feature with a wheel, and an attachment that physically and tightly secures the modular conveying feature to the support structure in at least two different positions. A tool-free mechanism can allow a user to free the modular conveying feature from the support structure for movement to another position. A system for adjusting a skateboard wheel position can include a wheel support structure having multiple wheel attachment positions, and a wheel assembly comprising a skateboard wheel and a base. The wheel can swivel with respect to the base and the base can join to the wheel support structure. The base and wheel support structure can tightly join to prevent rotation of the base with respect to the wheel support structure and that tightly retain the base in a first attachment position. A release feature can allow a user to easily loosen the base and reposition it in a second attachment position.
