  • Fat and fast

    Fat and fast

    27.5″ fat tires give you the best combo of all-terrain grip, stability, flotation, and fast-rolling speed

  • Adventure-ready fork

    Adventure-ready fork

    Farley's new, short-offset OCLV carbon fork puts you in an optimal position over the front wheel, upping traction over sketchy terrain while allowing for a shorter stem. A custom rack mount on the crown and thoughtfully positioned triple bottle bosses (64mm spacing) on the lower legs let you gear up without sacrificing handling. Protective rubber bumpers on the bottom of the fork legs keep Farley upright and manageable when the front wheel needs to come off.

  • Haul of the wild

    Haul of the wild

    Mounts all over the frame let you carry a wide variety of gear with endless customization options. Gummy bears? Extra layers? Camping gear? Haul it all.

  • Load up and bring on the big

    Load up and bring on the big

    Farley 9 comes with custom racks, a fender, frame bags, and drybag holders. Load up and get ready for your biggest adventures.

  • Keep it clean

    Keep it clean

    Internal routing helps to protect Farley's components from the elements and makes it easy to mount gear

  • Rapid Drive 108 rear hub

    Rapid Drive 108 rear hub

    With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.

  • A better way to produce aluminum

    A better way to produce aluminum

    Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Overview

Farley 9 is the ultimate fat bike for the explorer who doesn't want to hold back. What sets this Farley apart is its fully-equipped, frame-specific package of racks and bags for loading up with everything you need to get way, way beyond the beaten path. Extra-wide 4.5-inch tires give you amazing traction over loose terrain and progressive trail geometry gives you extra stability and efficient pedaling. The frame and fork are loaded with extra mounts for adding even more accessories.
