Using the Thule VeloCompact 925 is easy. First, connect the carrier to your towball using the adjustable one - hand coupling. The pre - assembled design means you don't need any tools. Next, use the detachable bike arms and long wheel straps with pump buckles to quickly mount your bikes. To access your vehicle's boot, just use the smart foot - pedal tilt. When you're done, fold the carrier flat for easy storage. As for maintenance, regularly check the locks to ensure they're working properly. Keep the wiring plug clean and dry to prevent any electrical issues. And if you notice any damage to the carrier or the bike - mounting parts, get them repaired or replaced right away. Also, make sure to lock your bikes and carrier whenever you leave them unattended to keep them safe.
