Amazon.com Carry up to two bicycles on road trips or camping excursions with the Allen two-bike carrier hitch. The hitch insert--which fits 1-1/4- and 2-inch receiver hitches--is easy to operate and super secure for your bikes. Just attach it to your hitch, then use the tie-down cradle system to individually secure and protect the bikes. The carry arm accommodates a wide range of frame sizes and designs, so you can carry your kid-size mountain bike or adult road bike with equal confidence. And you don't have to remove your bikes to access the back of your truck or SUV, as the rack tilts back for easy lift-gate access and folds out of the way completely when not in use. Also equipped with a no-wobble bolt to keep the rack from moving inside the hitch, the two-bike carrier is colored with a black powder-coated finish. About Allen Bike Racks Started out of founder Dick Allen's garage in 1967, Allen Sports is committed to producing the highest-quality, easiest-to-use bike, parking, and storage racks on the market. Dick Allen, a onetime aerospace engineer, opened Allen Sports after building a prototype bike carrier in his Lincoln, Massachusetts, shop in his free time. The bike enthusiast tested the trunk-mounted carrier--made of electrical conduit, metal strapping, and fire hose casings (for padding)--on weekend excursions. Shortly afterward, Allen took his design to consumers, moving from local to national sales by 1971. Today, the company owns more than three dozen patents and operates three warehouses nationally, two factories abroad, and sells products in more than a dozen countries around the world.
