The Bones Hitch 4-Bike rack is born out of the design and function of the best-selling Bones rack and brought to life in the form of a hitch rack. You wanted a nicely designed, tilting rack at a great value, and you wanted it to be lightweight. The result is the Bones Hitch. The Bones Hitch is one of the lightest racks in the marketplace yet every bit as strong and durable.
