Abstract: A support member is rotatably fastened to a bracket that is configured for mounting to a bicycle seat tube just above the bottom bracket. The support member is movable between a stored position where it is generally parallel to and just behind the seat tube and a lower position to support the weight of the bicycle. A locking mechanism includes an X-shaped recess in a head of the support member and a pair of detents in the bracket. The detents extend from a projection that is flexibly connected to the bracket. The projection bends slightly to permit movement of the support member between positions.
