I guess if preserving the bikes isn't important, and the main thing is access to the rear hatch, but the guy in the video put a Madone on that rack. Sacrilege. The front fork was swinging around freely, the wheels can spin freely in the wind, and there was just a rubber band to stop the bike from swinging fore and aft. Their idea of a lock was a cable around the frame. A hitch rack is a good idea for those who can't easily reach the roof rack, and for mountain or cross-country bikes that are already dirty from riding offroad, but the racks that hold the bikes in wheel trays are much more solid. This is Walmart stuff.
