Farley 5 is a go-anywhere fat bike built for snow, sand, and rugged trail missions. Updated geometry with a slacker head tube and steeper seat tube adds stability and pedaling efficiency. A carbon fork with multiple mounts lets you gear up for the long haul, while wide, grippy tires keep you floating through deep snow, soft sand, and everything in between.
  • 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 fast

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

Fat and fast

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

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.

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

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

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.
