Once you've slipped the RidgeBack 4 into your 1.25in or 2in hitch receiver, just twist the SpeedKnob to lock it in place and ensure your shiny new rack doesn't end up as a highway speedbump. When you cinch your bikes down into the anti-sway cradles with the flexible ZipStrips, they won't smash into each other or the back of your car, even when you're rallying down bumpy dirt roads. The built-in bottle opener will help you guzzle down some icy refreshment when you've reached the trailhead at the end of the dusty drive. It comes fully assembled, so it's far easier to use than your homemade contraptions, and tilts back (or folds flat) via the UpperHand lever to provide easy access to the back of your vehicle and all your carefully stashed snacks.
