The TRS hitch rack will carry two 50 lb. bikes with up to 4.5" tires. It uses our new quick release spring system to tilt the rack down and fold it up flat against the car. The two bikes will sit on anodized aluminum trays with a rotating tire cage and multiple ratcheting wheel straps integrated. A uniquely designed hook is used to hold the bikes by the front tire. Max wheelbase is 48". Fits both 1-1/4" and 2" hitches.
