Using this Yakima towball bike rack is easy. First, make sure your vehicle has a 50mm tow ball. Then, use the 'Just Click' system to attach the rack to the tow ball. The red/green indicator will show you if it's properly attached. Adjust the extendable wheel tray to fit your bike's frame size. You can load up to three bikes, and there's an option to add a fourth. When you need to access the rear of your vehicle, use the tilting system. For heavier ebikes, note the 60kg weight limit. If you want an easier way to load your bikes, consider buying the optional drive - up ramp. As for maintenance, regularly check the integrated lock system and the attachment to the tow ball. Keep the rack clean and dry to prevent rust. If you notice any issues, get it checked by a professional.
