Using this Thule bike rack is a piece of cake. First, make sure your towball is 50mm ISO compliant. Attach the rack to the towball. Thanks to the initial stability of the towbar coupling, you can easily mount and adjust the rack before closing the tightening handle. Then, place your bikes on the rack. Use the detachable bike arms with Thule AcuTight torque limiter knobs to secure the bikes. Tighten the knobs until you hear a 'click'. If you have fat bikes, use the adjustable pump buckles and extra - long wheel straps to fasten the wheels. When you need to access your trunk, just use the smart foot pedal tilt. For transport, you can carry the rack easily using the integrated carrying handles. And don't forget to use the included locks to secure your bikes to the rack and the rack to the towbar. As for maintenance, keep the rack clean. Check the knobs, straps, and locks regularly to make sure they are in good condition. If you notice any damage, get it repaired or replaced right away.
