Abstract: Apparatus for attachment as an accessory to a cycle such as a bicycle, for stabilizing the cycle upon rearward rotation thereof about the rear wheel when the front wheel is raised from the surface upon which the cycle is located. The apparatus comprises a pair of elongated members secured to the structure of the cycle and extending generally rearwardly from the cycle and a brace extending rearwardly from the cycle to remote portions of the elongated members. A wheel arrangement is carried at remote ends of the elongated members for rolling engagement with the surface at a point rearward of the cycle upon rearward rotation thereof about the rear wheel axis through a predetermined angular extent.
