Abstract:
An all-terrain bicycle comprising a bicycle frame having a front and a rear fork to which is removably secured a front and a rear wheel, each said wheel having a circular rim, spoke means interconnecting a central hub of each of said wheel to said rim, said rear wheel having a chain sprocket secured to said central hub, means to impart rotation to said chain sprocket, a seat and handlebars secured to said frame, each said rim having a surface engaging support shoes assembly attached thereto to provide support of said bicycle on a surface, said surface engaging support shoes assembly comprised of a plurality of support plate members attached about an outer periphery of each said rim, said support plate members being connected to said outer periphery by a pivoting connection whereby each said support plate member can pivot independently along an axis transverse to the plane of said rim, said pivoting connection being constituted by a pair of spaced-apart attachment flanges projecting from a rear wall of each said support plate members, a removable fastener connectable between said attachment flanges and adapted to extend through a connecting cavity formed in a circumferential side wall of said rim, said connecting cavity being dimensioned to permit said fastener to articulate within said connecting cavity to permit said support member to pivot along said axis transverse to the plane of said rim, said rim has an outer peripheral wall which is of dome-shape cross-section to receive thereon in frictional contact a curved transverse cavity formed in said rear wall of said support plate member, said outer peripheral wall transferring a load on said bicycle onto said concave curved transverse cavity.
