The Swagman E-Spec E-Bike Hitch Rack is designed for heavy-duty use, able to transport up to 2 bikes at a max weight of 70lb each, making it a great option for e-bikes. The padded ratchet hooks fit most frame shapes and sizes, and fastens down over the top tube to hold the bikes firmly without scratching the frame. Individual wheel trays hold your wheels securely, and will fit bikes with 20 - 29in wheels and tires up to 3-inches wide, though you can purchase separate fat tire trays to that will fit tires up to 5-inches in width. The rack folds up against the rear of the vehicle when not in use, and is equipped with locks for the bikes as well as a locking threaded hitch pin to help deter theft. For those of you that own RV's or travel trailers, the E-Spec rack is convertible between a folding e-bike rack and a non-folding RV approved e-bike rack with the installation of the reinforced bolt (included).
