Abstract
A bicycle safety apparatus for stabilizing a bicycle when the front wheel of the bicycle is elevated above the ground which includes rollers or wheels that are mounted on the ends of rigid arms that extend outwardly and rearwardly from the back wheel of the bicycle. The rollers or wheels are maintained in spaced apart relationship with the axis of the rollers or wheels being in approximately the same horizontal plane as the rear axle of the bicycle, when both wheels of the bicycle are in contact with the ground. The rollers or wheels of the safety apparatus are substantially smaller than the wheels of the bicycle such that when the front end of the bicycle is elevated, a three point contact is made by the rear wheel of the bicycle and the spaced apart rollers or wheels to stabilize the bicycle and prevent it from tipping over backwards.
