Using the Thule Apex XT bike rack is a breeze. First, make sure your vehicle's hitch type matches the 1 - 1/4' or 2' receiver of the rack. Attach the rack securely to the hitch. When you want to load your bikes, use the ratcheting cradle strap to quickly attach the bikes to the rack. The top - tube mount design makes it easy to secure them. If you need to access the rear of your vehicle, simply use the HitchSwitch lever to tilt the rack down. When you're not using the rack, fold down the bike arms for easy storage. Remember, each bike should not exceed 37.5 in weight. To keep your rack in good condition, clean it regularly with a mild soap and water. Avoid using abrasive cleaners that could damage the black finish. Check the straps and connections periodically to ensure they are tight and in good working order.
