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, a Bontrager Haru carbon fork, a wide-range Shimano Deore 1x10 drivetrain, 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.

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.
