Abstract: An adapter handle for use on wheeled vehicles having two spaced-apart handles for application of propulsion forces and steering formed by an elongate arm extensible between the spaced-apart handles of the wheeled vehicle which includes a clamp adjacent each end thereof to enable the adaptor handle to be rapidly coupled onto the spaced-apart handles and a single hand grip extending substantially from the center of the arm. The clamps are formed as over-center latches having plural contact shoes and shoe spacers which allow the adaptor handle to be used on wheeled vehicles having differing sized handle grips. Additionally, one or more auxiliary hooks are provided to enable storage of desired items upon the adaptor handle during use.
