It's right for you if...
You're likely to ride year-round, even when it's snowing, and want a fat tire bike that gives you extraordinary capability and traction at a great value.
The tech you get
A lightweight Alpha Platinum Aluminum frame with Stranglehold dropouts, internal derailleur and dropper post routing, a Bontrager Haru carbon fork, a wide-range Shimano Deore 1x10 drivetrain, SRAM Level hydraulic disc brakes, and Tubeless Ready SUNringlé Mulefüt wheels paired with extra-grippy 27.5x4.5˝ Bontrager Gnarwhal TLR tires.
The final word
Fat bikes are ridiculously fun. They're grippy and stable, but the best thing about them is that they get you outside in more seasons. If you're looking for a fun alternative to riding the roads or trainer through the winter, you won't find a better value than Farley 5.

Features
27.5˝ fat tires
More efficient 27.5" fat tires keep you rolling faster, especially on groomed or packed snow.
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.
Tubeless Ready wheels & tires
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. Just add TLR rim strips, valves, and sealant.
Stranglehold dropout
Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
