Using the Camber 2 bike hitch rack is a breeze. First, make sure your vehicle has a 1.25 - inch or 2 - inch hitch receiver and transfer the rack to it. Then, use the ratcheting cradle strap to quickly attach your bikes to the rack. Remember to take advantage of the 7 - inch spacing between bikes for better safety. When you're not using the rack, fold down the bike arms to save space. To access the rear of your vehicle, just use the HitchSwitch lever to tilt the rack down. For maintenance, regularly check the anti - sway feature and the ratcheting cradle strap for any signs of wear. Keep the rack clean to ensure its long - term performance. And always double - check that your bikes are properly secured before hitting the road.
