Budget for the Fit Kit: the rack and the bike-specific Fit Kit are separate line items (roughly $60 extra). Run your bike through OMM's Fit Kit Finder before checkout so the right hardware shows up with the rack.

The Bike Cave Verdict

Ben's Take

Gear-pick status: specs and reputation, not an on-camera test. This answers the number-one rack question ebike riders actually have: "my bike has zero eyelets — now what?" The Divide doesn't care about eyelets. It mounts through the axle, so the load rides on the hub instead of your frame — which is why it's safe on carbon, full-suspension and fat-tired ebikes, and why OMM keeps a dedicated ebike FAQ saying exactly that. 70 lb axle-mounted is more than most people should ever strap to a bicycle. Made by the Robert Axle Project crew, guaranteed forever. Just know the Fit Kit is a separate purchase.

👍 What stands out

  • Fits almost any bike: eyelets, thru-axle or QR via Fit Kit
  • 70 lb axle-mounted, 55 lb on eyelets
  • Safe for carbon and full-suspension frames when axle-mounted
  • Runs as a front or rear rack
  • Height-adjustable dropouts keep the load low and planted
  • Real deck for dry bags plus rails for standard panniers
  • Lifetime warranty, made by the Robert Axle Project crew

👎 What to know

  • Fit Kit is a separate, bike-specific purchase (~$60) — check OMM's finder first
  • All-in you're at roughly $230–$250
  • 3.9" × 10.5" deck is a strap-down platform, not a basket
