Trek Farley 7

Farley 7 is a burly fat bike built for roaming trails no matter the season. From dusty summer doubletrack to ice-packed singletrack, the huge 4.5-inch tires give you sure-footed stability and tons of traction. A suspension fork takes the sting out of rowdy roots and rocks while the slacker head tube angle gives you more confidence when the trail turns steep. Mounts all over the frame make it easy to equip it with all of your essentials for adventure.

• All the mounts make it easy to add accessories and customize Farley for how you want to roam
• The suspension fork eats up rocks and roots for a smooth ride, and it also slackens the head tube angle for added confidence and stability
• You'll stay afloat on snow, sand, mud, and dirt thanks to its huge 4.5-inch tires
• 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

Super smooth suspension

Farley 7 comes loaded up with 80mm of front suspension to take the edge off rough terrain. It also slackens the head angle for a more stable ride when the trail gets steep.

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 Farley's 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.

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
