The Swagman ORIGINAL 4 is a hitch mount hanging bike rack that carries four bikes. Truly tried and tested, it’s our original bike rack. It’s RV Approved, meaning that it is designed to withstand the extra stressors of being on the back of your RV, travel trailer, or 5th wheel. The padded rubber cradles keep your bikes safe and secure and the strong steel construction is durable. A locking knob secures your bikes to the rack. It also can swing down to make loading and unloading easier. It also comes with a lock for the hitch so somebody wouldn't be able to remove it from the vehicle.
