Abstract: An operator can be connected to a moveable vehicle used to support a person or object, via a control device including a belt and pair of control poles. The control poles each can be telescopic, or adjustable in length, and can include resilient portions allowing for flexing and shock absorption. Anchors can be attached by hand to a handle bar or other support member(s) of the vehicle. The control poles then can be attached by hand to anchors on the belt and the anchors on the handlebar. The control bars can include rotatable portions such that the device can attach to any appropriate support member. The vehicle anchors can include an adjustable member, such as a strap, that allows the anchors to fit most vehicles. The adjustability and shock absorption of the attachment device provide a level of control and comfort for the operator.
