Farley 5 is the ultimate go-anywhere fat bike. Arctic tundra? Farleys game. Sandy desert singletrack? Farleys lofty tires will keep you afloat. A winter bikepacking mission through rugged terrain? Sounds like a walk in the park. Farleys 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 youll 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 fast

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

Adventure-ready fork

Farleys 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 Farleys 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.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
