Constructed from heavy duty steel tubing, these universal bike racks are heavily padded to prevent any damage to your vehicle's rear hatch or trunk. Utilizing six adjustable straps, the strap down bike carriers can mount snuggly and securely to any vehicle. When not needed, simply undo the straps and fold the carriers up to store them.
