Product Details

Going fat isn't just a fun way to ride — it's a ride revolution. The security and control that the wheel system found on our Fatboy provides is unparalleled. You get dramatically more traction, grip, and floatation than with traditional mountain tyres, all without sacrificing climbing efficiency. The end result is easy to explain—you have way more fun. And to make sure of it, we built the Fatboy with a durable list of components that are low-maintenance and eager to perform season after season. Have more fun — go fat.

Our Stout XC Pro one-by crankset features a forged alloy construction that provides plenty of security from chain drop, while also leading the way for an efficient, lightweight, and simplified drivetrain with plenty of gear range for hard drives on the flats and climbs.
26x.4.6" Ground Control tyres help soak up bumps, while also providing a game-changing level of traction, control, and floatation for better handling out in the wild.

Med Fat Boy

I picked up a Fat Boy, and am I glad I did. I have rode it like three times in the snow, -5 to -15*C. It’s a sleeeeek little machine, very nice build, good package in it, tight frame, very playful.

Would Recommend?: Yes!

Great Beach bike

Great on any off road surfaces, including the only bike that can go through soft sand [Tyres 6/7 lbs]. Noisy on road, and I may have bought the wrong size as can't sit on it well, as the crank is too far back, when against a head wind. If it was an ebike then it would be awesome...
