Trek Farley 5 Bike
Farley 5 is our best value fat bike and your ticket to all-season freedom. It rolls over snow, sand, roots, and rocks with the stability and traction of a monster truck on wide, beefy tires. A 1x Shimano drivetrain and lightweight aluminum frame make it a great choice for anyone who wants to ride a mountain bike year-round, no matter the weather.

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 retailer.
