This is the most common type of bike rack and hence why I’ll explain the installation process first. Hitch mounted bike racks require a tow hitch to mount to the vehicle. The racks are the strongest type of bike rack on the market as the bike rack connects directly to the chassis of the vehicle, reducing any wobbling of the rack and bikes.
To install a hitch-mounted bike rack, first ensure your hitch receiver is compatible with the hitch, if not there are adaptors available. The hitch of the bike rack connects to the hitch receiver as pictured below. Then simply line up the bolt so that it can slide the whole way through, locking the bike rack in place.
This should be a snug fit and the amount of play left in the rack should be minimal. If the rack has a lot of movement, the hitch has a nut that can be tightened to reduce the level of free play, securing the bike rack firmly. The two images below depict this well.
