Thule Helium bike racks are the lightweight alternative to traditional bike racks. Made from heavy-duty, feather-light aluminum, Helium bike carriers are about the half the weight of steel bike carriers. Each rack securely holds bikes in place without any frame contact, making this rack ideal for carbon frame bikes. The ratcheting wheel loops make securing bikes a breeze, plus they fold down when the rack is not in use. Helium bike rack work with both 1.25 in. and 2 in. hitch receivers, provide access to your vehicle's rear hatch via the HitchSwitch lever (even with bikes on it!), and fits bike wheels up to 29 in. in diameter and up to 3 in. wide. Backed by Thule's limited lifetime warranty.
