Offering an ideal solution for hauling your family's bikes or giving your buddies a lift to the trail, the Rhino Rack Premium Hitch Mount 4 Bike Carrier is an ultra efficient way to carry four road or mountain bikes if you already have a 1. 25 or 2 inch receiver on your vehicle. This four bike carrier is constructed of heavy duty steel and reinforced plastics, ensuring durability for years to come. Featuring a top loading, swing arm design, this four bike carrier folds down when it's not in use for a more streamlined, aerodynamic shape. In addition, the carrier's release pin allows you to access your trunk or tailgate without removing the carrier itself. This carrier comes complete with securing cables and tie down straps for securely cinching down your valuable rides, and it also includes a pad to protect against dings and scratches when the road gets bumpy.
