Product Details

Trek Farley 5 Fat Bike 2025

Farley 5 is the ultimate go-anywhere fat bike. Arctic tundra? Farley's game. Sandy desert singletrack? Farley's lofty tires will keep you afloat. A winter bikepacking mission through rugged terrain? Sounds like a walk in the park. Farley's geometry is more capable than ever with a slacker head tube angle for more stability and a steeper seat tube angle for pedaling efficiency and comfortable reach. Up front, its carbon fork is loaded with tons of mounts, so you'll be able to load up gear for the adventure of your dreams.

It's right for you if...

You don't want to limit your adventures to one season. Come snow, sand, or singletrack, you're ready to rip and want a bike that can handle it all. You like your days long, and your adventures longer. You appreciate the thoughtful details, like plenty of mounts for hauling a week's worth of gear to keep you going far beyond the last cell tower.

The tech you get

A rugged alloy frame with geometry that's built to handle it all. Huge 4.5-inch tires that keep you floating over snow, sand, mud, and dirt. A carbon fork with plenty of mounts for loading up racks and bags. An internally routed dropper post that lets you get behind the saddle on descents. A wide-range 10-speed Microshift drivetrain with a big cog for taking the sting out of steep climbs when your bike is fully loaded.

The final word

For the explorer who knows no bounds, Farley 5 is the perfect go-anywhere adventure machine. It's built for you to choose your own adventure and load it with all of the racks and bags you need to get you there.

Why you'll love it

  1. All the mounts make it easy to add accessories and customize Farley for how you want to roam
  2. It comes with a carbon fork that has lower leg mounts for gear cages, mounts for our custom front rack, and rubber bumpers to protect the dropouts when the front wheel is removed
  3. Its huge 4.5-inch tires will keep you floating over snow, sand, mud, and dirt
  4. The progressive trail geometry feels more capable and confident than ever
  5. The internally routed dropper post lets you move around on the bike and get behind the saddle on steep descents

How tall are you?

To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inseam?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
