  • Patent number: 7060009
    Abstract: Stationary bicycle riding on conventional bicycle rollers is enhanced and rendered safer by the use of this Bicycle Roller Balance Device. The sought after balancing characteristics of roller riding are unaffected; the rider enjoys complete freedom of movement within the width of the rollers, while at the same time is prevented from the perils of traveling off the sides of the rollers. This is accomplished by a system of curbs and bumpers. The curbs are near-vertical components that deflect an errant bicycle wheel back toward the center of the rollers. The bumpers are padded surfaces that deflect the rider back toward the center as well. Furthermore, stepping platforms are provided to aid the rider in more safely mounting and dismounting the bicycle. The device is self-contained and modular in nature, and can be assembled or disassembled readily by the user.
