Product Description


2020 Farley 7 is the mountain biker's fat bike. It's built to feel like a traditional mountain bike with way more capability. The lightweight aluminum frame, 1x11 Shimano drivetrain, and Manitou Mastodon fork make it the ideal ride for trail-shredders who want to get rad in every season.


  • If you were under the impression that fat bikes were sluggish, this bike will change your mind
  • The combination of the Manitou Mastodon fork and 4.5" tires make it easy to charge through snowy trails and rock gardens alike
  • It's a four-season freedom machine that lets you ride outside all year long
  • The 27.5x4.5" tires deliver more speed and traction than their 26" counterparts
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8", for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local SCHEELS.

Almost perfect Fattire ride for big riders
Finally an XL came into stock with 4 snow rides left in the season! It's darned fun and I don't consider it that heavy relative to my size. I'd still change the following items to make the bike even better for me. Make a 5 inch wide 27.5 tire. Rear shock/frame Like the Farley EX that fits 5" tires. Longer dropper post on XL frames. Higher max weight capacity on all XL sized bikes. I'm 270 6'4" so with the weight of the bike that means I'm not allowed to cary any gear to stay within Treks 300lb load limit for the bike.
In the future I'll consider converting to a Rolhoff geared hub and Gates Carbon belt one day. The Strangle hold dropouts make it possible.
The Rapid Drive 108 rear hub makes peadling over obstacles much easier with large wheels, but I still prefer Onyx hubs because they are silent and that's pretty nice in the winter when everything else is too.

This bike is awesome
This bike is awesome, in winter or even summer. It is very fast and the rolling of the wheels is great.

Great Bike!!!
I like to go to my soccer games riding my bike, it's a great warm up and on the way back it's so comfortable that's not bad at all after playing a great game of soccer.

The #1 bike in my stable!
I ride this bike summer and winter, it really hooks up on the single track in the summer. In the winter with studded tires it's a blast on frozen lakes and groomed single track.

It works
I've been on about 4 rides with the Farley 7 so far. I'm enjoying it and glad I bought it. From the bike shop, it weighs in at 37.5 lb, tubeless setup. It's heavy and slow but, I knew that going in. I don't really feel like it's that heavy once I'm on it. I did one ride on 2" of snow over dirt; bike did great, excellent traction at lower pressures. I think the suspension fork is probably not needed, but, I didn't have any choice. The NX derailleur works ok, not as spot on as I'd expect from higher end group; wish it was GX. But, it's allowing me to get out pretty much regardless of weather and I love that.

Great bike for the desert southwest
Great bike for riding in the desert southwest. Floats across the deep sand washes and through rock gardens. By far the best "desert sled" I've ever ridden (and I've been on a MTB of some description or another since the early '80's).

Great bike for the beach, snow and any off road activity
My first off road bike. Surprisingly agile and responsive in spite of its size and weight. Goes through or over anything.

High torque Battle Tank
The Farley 7 cruises through muck, mud and beach sand. The torque when in the lowest gears is unreal! It's also the sickest pit bike when I take my son to motocross races.
