Using this Yakima StageTwo +2 addition is easy. First, attach it securely to your Yakima StageTwo 2 hitch - mounting bike rack. Then, place your bikes on the trays. The stadium seating and offset tray design will help keep your bikes stable and minimize interference. When you need to access the rear of your vehicle, just use the forward - facing remote tilt lever. For security, use the integrated locking cables along with your own lock. As for maintenance, regularly check the attachment points for any signs of wear or looseness. Keep the trays clean to ensure smooth bike placement. Also, lubricate the moving parts like the tilt lever from time to time to keep it working well.
