Abstract: A first support member is removably attached to the bicycle and a hinge end of a second support member is hingedly attached to an attachment end of the first support member that allows radial movement of the second support member in relation to the first support member. A wheel is rotatively connected to the second support member, at a wheel end of the second support member, distal from the hinge end. An adjustable preloaded strut is attached, at a first end of the strut, to the first support member. The adjustable preloaded strut is also attached, at a second end of the strut, to the second support member. An adjustable stop member is on one of two rotation restriction lobes to restrict the radial movement of the second support member toward the first support member. Hinge rotation stop tabs are on the hinge that connects the first and second support members to limit the amount of radial movement of the second support member away from the first support member.
