Using the Enduro 2 rack is easy. First, make sure your vehicle has a standard 50mm towball. Then, attach the rack to the towball. Adjust the wheel tray position according to the size of your bikes. Place your bikes on the rack, ensuring the wheels fit into the tray. The adjustable rubber sleeves will protect your rims. When you don't have bikes on the rack, you can fold down the center post to access your boot. As for maintenance, regularly check the towball connection for tightness. Clean the rack with a mild detergent and water. Keep the adjustable parts lubricated to ensure smooth operation. Also, remember to test the lightboard before each journey to ensure it's working properly for your safety on the road.
