Using the Hollywood Racks F1B bike rack is easy. First, make sure your vehicle is suitable as it fits most vehicles. Open the pre - assembled rack and position it on your vehicle. Use the patented hinges to lock it firmly in place. You can adjust it with a simple thumb pressure. Place your bicycles on the rack, making sure each bike (up to 3 and not exceeding 35 LBS each) is properly secured. When you're done using the rack, fold it flat for easy storage. For maintenance, regularly check the vinyl - coated support arms, hooks, and foam pads for any signs of wear. Clean them with a mild soap and water solution. Keep the rack dry to prevent rusting. If you have any questions, refer to the included instructions.
