The SportRack Crest Deluxe 4 hitch platform system bike carrier is a fully foldable, compact, and easy-to-use hitch-mounted bike rack that can accommodate up to four bikes. It's suitable for most types of bikes thanks to the multiple adjustment points that allow you to customize it to suit the type of bike you're carrying. This platform-style rack makes sure your tires are mounted on the rack, preventing your bikes from rocking back and forth.
