Trek Farley 5 Fat Bike 2025
The Farley 5 is the ultimate go-anywhere fat bike. Arctic tundra? Farley's game. Sandy desert singletrack? Farley's lofty tyres will keep you afloat. A winter bikepacking mission through rugged terrain? Sounds like a walk in the park. The Farley's all-new geometry is more capable than ever with a slacker head tube angle for more stability and a steeper seat tube angle for pedalling efficiency and comfortable reach. Up front, its carbon fork is loaded with a variety 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 lamp post.
The tech you get
A rugged alloy frame with all-new geometry that's built to handle it all. Huge 4.5-inch tyres 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.
