This invention is a single-piece side wheel attachment member for removably attaching an auxiliary side wheel to a bicycle. The attachment member comprises a single-piece molded structure, including an upper vertical portion and a lower substantially horizontal spindle portion connected to said vertical portion through a C-shape compliant structure for allowing said spindle portion to move vertically when subjected to force. In its natural unbiased condition, the vertical and horizontal portions of the member extend generally perpendicular to one another. The upper vertical portion includes a projection and at least one through-hole for insertion on the rear wheel axle of the bicycle. The horizontal spindle portion is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends of the attachment member can angularly move relative to one another due to the C-shape compliant structure. The novelty of this invention resides in the structural simplicity of the side wheel attachment member which is, as previously stated, constructed from a single piece of material molded into a C-shape compliant structure.
