Using the Thule VeloCompact 2 Bike Rack is easy. First, make sure the rack is properly attached to the towball using the provided locks. To load a bike, use the foot - pedal tilt system to access the carrier easily. Then, place the bike on the rack and use the extendable wheel holders and wheel straps with quick - release pump buckles to secure it. Remember, the total load limit is 46kg and 25kg per bike, so don't overload it. Avoid using it for e - bikes or long - wheelbase bikes that exceed the load limits. For maintenance, regularly check the locks for proper functioning. Keep the integrated lights clean and check the electrical adapter for any signs of damage. If you're not using the rack for a long time, store it in a dry place to prevent rust.
