Abstract
A seated vehicle comprises a frame, one or more first wheels at a first position relative to the frame, one or more second wheels at a second position relative to the frame, and a wheel-positioning system. The wheel-positioning system includes one or more arms pivotally coupled to the frame, and an adjustment mechanism operatively coupled to a first position of the one or more arms. The one or more first wheels are operatively coupled to a second position of the one or more arms. The adjustment mechanism moves the one or more arms between a first position and a second position so that the one or more first wheels are in a first position relative to the one or more second wheels when the one or more arms are in the first position and are in a second position relative to the one or more second wheels when the one or more arms are in the second position.
