Using this Thule DoubleTrack Pro XT bike rack is a breeze. First, make sure your vehicle has a 1 - 1/4 - inch or 2 - inch receiver. Slide the rack into the receiver and secure it properly. When loading your bikes, place them on the tray - style mounts and lock them to the rack. You can also lock the rack to the receiver for extra security. To tilt the rack for easy access to your vehicle's rear, use the convenient HitchSwitch feature. When you're done using the rack, fold it up for compact storage. As for maintenance, regularly check the locks and mounting points to ensure they're in good working condition. Clean the rack with a mild soap and water to keep it looking great. Avoid using abrasive cleaners that could damage the finish. And always make sure the weight of each bike doesn't exceed 37 lbs to keep everything safe and stable.
