Farley 5 is the ultimate go-anywhere fat bike. Arctic tundra? Farley's game. Sandy desert singletrack? Farley's lofty tires will keep you afloat. A winter bikepacking mission through rugged terrain? Sounds like a walk in the park. Farley's geometry is more capable than ever with a slacker head tube angle for more stability and a steeper seat tube angle for pedaling efficiency and comfortable reach. Up front, its carbon fork is loaded with tons of mounts, so you'll be able to load up gear for the adventure of your dreams. All the mounts make it easy to add accessories and customize Farley for how you want to roam It comes with a carbon fork that has lower leg mounts for gear cages, mounts for our custom front rack, and rubber bumpers to protect the dropouts when the front wheel is removed Its huge 4.5-inch tires will keep you floating over snow, sand, mud, and dirt The progressive trail geometry feels more capable and confident than ever The internally routed dropper post lets you move around on the bike and get behind the saddle on steep descents Fat and fast27.5″ fat tires give you the best combo of all-terrain grip, stability, flotation, and fast-rolling speedAdventure-ready forkFarley'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 wildMounts 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.Keep it cleanInternal routing helps to protect Farley's components from the elements and makes it easy to mount gearRapid Drive 108 rear hubWith 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 aluminumStarting 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.
