The Vevor roof bike rack is a foldable upright roof-mount carrier designed to transport one bike securely on compatible T-slot crossbars. It supports bikes with 20"-29" wheels, tires up to 2.7" wide, and a maximum load of 33 lbs. Multiple locking points and fixed straps help keep the bike stable during travel, while soft rubber pads help protect your vehicle's paint. Its aluminum alloy construction is built for durability in sun, rain, and snow. The foldable design also makes storage easier when the rack is not in use.
