It's right for you if...
You want to ride year-round, even when it's snowing, and you’re looking for a fat tyre bike that gives you extraordinary capability and traction at a great value.
The tech you get
A lightweight aluminium frame with horizontal sliding dropouts, internal derailleur and dropper post routing, a Bontrager Haru carbon fork, a wide-range Shimano Deore 1x10 drive train, SUNringlé Mulefüt wheels paired with a 108T Rapid Drive hub for instant engagement and extra-grippy, studdable Bontrager Gnarwhal TLR tyres.
The final word
Fat bikes are ridiculously fun. They're grippy and stable, but the best part about 'em is that they get you outside in more seasons. If you're looking for a fun alternative to riding the roads or training through the winter, you won't find better value than Farley 5.
favorite_borderWhy you'll love it
- Farley 5 is the perfect bike for breaking into the winter shredding scene without breaking the bank
- The stability and traction of super wide tyres make you a more confident rider on any trail
- It's a four-season freedom machine that lets you ride outside all-year long
- Horizontal sliding dropouts lets you fine-tune your geometry – run it long for stability or shorter for nimbler handling
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
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.
27.5˝ fat tyres
More efficient 27.5" fat tyres keep you rolling faster, especially on groomed or packed snow.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
