Hollywood Racks Sport Rider 2-Bike Platform Style Hitch Mount Rack This heavy-duty platform-style bike rack mounts on a 1.25- or 2-inch hitch and folds flat against the back of a vehicle when not in use. The rack uses padded universal top clamps and adjustable wheel holders. Bikes need simply to be dropped into the wheel holders and clamps slid down onto the frames. Velcro wheel straps add security. The rack carries a limited warranty against defects. About Hollywood Racks Hollywood Racks started in 1973 when they began making trunk racks in the back of our bike shop in Hollywood, CA. As a retailer, the company knew exactly what people needed: good quality products that were easy to use. They earned a great reputation fast and began selling racks to other dealers, and later to the bike companies.
