Best Racks for Rivian R1S

The Rivian R1S (2022+) ships with factory crossbars integrated into the roof structure — a glass panoramic roof with embedded aluminum crossbar channels. Unlike traditional vehicles, the R1S does not use bolt-on rails or clip-on feet. The factory crossbars are the only mounting interface. Rivian's factory crossbars provide T-slot channels compatible with Thule and Yakima T-track accessories (ski racks, bike mounts, kayak cradles). Rail-to-rail span: approximately 44 inches. Crossbar spread: fixed at approximately 32 inches (not adjustable — they are structural to the roof). For cargo boxes: Thule and Yakima boxes with T-track mounting adapters bolt directly to the factory bars. The maximum dynamic roof load is 150 lbs — and this is a HARD limit on an EV where every pound affects range. [ADD PERSONAL EXPERIENCE] Critical EV consideration: 150 lbs of roof cargo on a vehicle with 0.30 Cd drag coefficient creates measurable range reduction. Expect 8-15% range loss with a loaded cargo box at highway speeds — plan charging stops accordingly. [ADD ORIGINAL PHOTO]

The R1S does not include a factory hitch receiver in the traditional sense. Rivian offers the Powered Hitch (optional accessory) — a motorized 2-inch receiver that deploys from behind the rear bumper via the vehicle's touchscreen interface. Rated at 3,500 lbs towing / 350 lbs tongue weight. When retracted, the receiver is completely concealed — maintaining the R1S's clean rear design. When deployed, any standard 2-inch accessory mounts: cargo carriers, platform bike racks, hitch-mount ski racks. For R1S models without the Powered Hitch: aftermarket solutions are limited due to the skateboard battery platform and structural aluminum rear subframe. Consult Rivian service for hitch installation options — traditional bolt-on hitches may not be compatible with the EV architecture.
