Super, fat

Farley changes the game for fat bikes. With lightweight carbon or alloy frame options and the ability to accommodate 5" tires and a variety of wheel sizes, Farley is the quickest and most versatile fat bike ever.

Fat bikes give you more places, more seasons to ride. From dunes to drifts, race to recreation, Farley lets you tackle anything, any time, for any reason. Fatten up this season.

Full fat

Farley's wide 197mm rear axle spacing accepts tires up to 5" in width, meaning there's no adventure that can't be conquered by this go-anywhere machine.

Accommodates all tire sizes

Versatility is the name of the game. Farley now accommodates capable 26" x 5" or fast 27.5" x 4.5" tires, so you can dial your ride for your style of adventure.

Easy tubeless setup

Say goodbye to the added weight of tubes, and say hello to lower pressure and more traction. The rims on all Farley models make it easy to run tubeless for trail-hugging confidence.

Alloy and carbon option

The sophisticated fat bike frame bred from Trek's MTB legacy is available in alloy or OCLV Mountain Carbon.
