The Allen QR hitch rack is the perfect way to transport your bicycles on road trips or camping excursions. The quick install locking hitch insert allows you to install the rack into your receiver hitch wobble-free without needing any tools to secure. The patented individual tie-down cradles secure and protect your bicycles. The rack also incorporates folding carry arms that quickly and conveniently drop out of the way when not in use. The rack also tilts back for easy lift-gate access. Important installation note: never use on trailers.
