The 2022 FOES Mutz Gets New Geo Numbers and More

Press Release: Foes Racing

At Foes Racing, we are proud to announce the release of our 2022 Mutz fatbike frame. The next generation pioneer of mid-travel fatbikes is here!


The Mutz received a complete redesign. We lengthened the reach to a manageable 470mm (in size large) with a low seat tube at 457mm (L) for lots of drop. The frame now has a 65° head-tube angle paired with a 76° seat-tube angle and 150mm of travel to keep up with any normal trail or enduro bike.

The monocoque toptube and delta box maximize the stiffness of the frame. The rear triangle features the readily available SRAM Universal Derailleur Hanger for our rider’s convenience. We redesigned the Mutz with ease of use in mind and to take fatbike fun to the next level.


bigquotesCelebrating our 30th year in business, we are proud to stay true to our roots and continue to build top quality aluminum mountain bike frames in the USA. Since the very beginning, we have built innovative and dependable aluminum frames that are fun to ride. We are kicking off our 2022 lineup with our redesigned Mutz fatbike model.Brent Foes


The ’22 Mutz features the Foes signature modified single-pivot, low-leverage suspension design. We believe our design offers a better ride quality, prolongs service life, and simplifies the bike, giving you more time riding and less time maintaining. We carry shock options from DVO, MRP, and Fox and offer custom frame colors to tailor your bike to you.

 I love my Mutz. Its one bike for everything. I have 3 wheel sets ; 27.5x3.0, 26x4.0 and 29x2.5. For the trails I ride, I prefer a full suspension fat bike in the winter. Our trails are not groomed and are rougher in the winter. There are holes from people without snowshoes and a full suspension is so much better.

 If you’ve ever owned a Foes then you know that this bike is just an excuse to buy another one. It’s kind of hard to understand the craftsmanship without studying one in person. You know Brent Foes makes everything himself and the tooling as well?

This second generation of a model proves that it’s popular and making them money. It is such a unique bike that there are just enough people around to make it work for them.

I’d need to be filthy rich to justify a FS fat bike so I’ll keep collecting old Foes DH frames.

 I owned 2 Flys. 2003 model and a 2006, which passed away 2014 after 8 years of hard Shore use. I still have the frame hanging on my wall as a memento. Cracked completely around at the BB/downtube. Foes is by far the best manufacturer in terms of quality and ride. Both of my bikes had flawless welds, were dead arrow straight (remarkable considering all the welding and parts) and rode like a dream. The Curnutt shock was not the best at small bump compliance but nothing is perfect. I still wish my 2006 Fly was with me. But other than the Mutz they don't impress me anymore. Their bikes don't seem to have that "edge" to it anymore, or stand out. Could be the market and what they have to build but still....I keep checking up to see if anything new is coming out but when they abandoned the Fly I think it was a end of an era of sorts for them. The Fly was the ultimate free ride bike and they were very rare here on the Shore; don't think outside of me and my riding partner I ever saw one current with the time. An updated Fly I think would fly well with current models (pun intended).

 @blackfly: You and I talked a lot back in the day about our Flys. What a great bike. The Avalanche rear shock was awesome on it too.

 @kntr: Interestingly I sold my 2001 Ellsworth Dare for a 2003 Fly, and at the time I found the Dare to have a flat rear end; no ramp up and a linear rate. Could never get it to be either supply or not bottom out. I was going to put an Avy on it as an experiment but the Fly came around. I saw that Dare a few years later with the very Avy I would of put on it and it was for sale. I guess the platform shock didn't help. I will say my current Knolly Podium has the best rear end suspension feel and performance of any FS bike I have owned.

 They go so many things right with this version but there are two glaring oddities in the specs. One is sticking with 177mm spacing, this is pretty much a dying (dead) fat bike standard as most every manufacturer has moved to 197mm. The other is using an imperial shock sizing when all the shock manufacturers have moved to metric sizing on their new shocks.

I have long wanted a MUTZ as it could possibly be a one mountain bike solution for me, but I am glad I went with a custom fat frame instead.
  • 4 0
 I was surprised they stuck with 177 as well. Salsa was one of the others that used the 177 and have switched over to the 197. I got parts to build one of these up, but don't want to have to build a rear wheel just for it.
  • 3 0
 There could be something about that extra 20mm of 197 that interferes with a full sus version fatbike. Of the few options for full fat all have 177mm rear hubs. I’d also be all over it if it had a 197 rear end so I could plug and play my fat wheelsets.
  • 1 0
 @Klimbnbike: the trek farley EX full SUS fat bikes were 197mm. For the MUTZ it would not have interfered with anything but he would have been a bit more mindful of crank arm clearance with the frame. With a 197mm rear end the whole drivetrain is just moved out 10mm from the frame centerline, everything else remains the same
  • 1 0
 @pedalrepair: The 177 give you a better Q factor, but mostly companies have moved away from 177 and over to 197. I had bucksaw with the 177 and it was great till the frame seat stay snapped (common issue with the bucksaw) and now on a hardtail Norco Ithaqua with a Mastadon fork. I loved the Bucksaw but don't miss the full suspension that much and I ride the Norco over everything mostly year round.
  • 3 0
 @jbutland: that used to be true with 177mm bikes, but not really true these days when you have have the narrow q factor cranks (outward dished ring) and still have clearance for 4.8" tires. This is exactly what the Farley ex did and many other modern fat bike frames.
  • 2 0
 @pedalrepair: figured I’d be proven wrong as soon as I said they were all 177.
  • 1 0
 @jbutland: I agree on having a hard tail fatbike is probably enough as I split my ride time pretty fairly for regular trail riding between my 29 full sus, 29 hard tail, and my fatbike. Everyone I talk to that has a Lenz, bucksaw, or Farley ex loves them though.

 Probably not going to get a whole lotta PB love but I'm happy to see this new option. Also gave me a reason to check out the rest of their bikes - some other interesting models too.

 Make a 100-120mm version of this frame with similar (updated) geo, and I think you’d have something that would actually work pretty well for winter fat bike riding and warmer season trail riding. Have to side with those saying that a 150mm FS fat bike is silly, and really won’t be ideal for anything in my opinion.

I live in the Midwest and can attest that the Salsa Bucksaw (RIP) was and still is a bike you see a lot of, because it rode like a half decent trail bike in dry conditions but could obviously still be used on groomed trails in the winter, where tire volume and pressure are everything and suspension really doesn’t do much for you unless the trail is post holed from walkers, etc.

 You see the problem is...You're inside the box and Foes is outside the box.

 @MattP76 don't know about mullets yet, but far bikes are no fad. Yes they are certainly not for everyone but they have been around for a long time and will be here for a long time to come as well.

I think the misconception that most people have with far bikes is that they have only ever riding a cheap generic one that rides exactly how they expect it to, slow and cumbersome. Once you get into the higher end stuff they change dramatically. They become lively and very capable.

 Foes, please make DH bikes again with 9.5in shock eye to eye dims. But with a steep seat angle. We don’t care how much it weighs.
  • 5 0
 Why a steep seat angle on a DH bike? Do you pedal yours around while seated often?

 Really wanted to support this (local to me) company in recent times, but their geo hasn't caught up with said times... Nice to see this as a start.

 I don't get the need for a long travel fat bike. I love my kona wozo but riding it on dry trails the tires show their sidewall weakness. Didn't know the mastodon pro is now available in 150mm but with 34 stanchions I'd keep my trail/enduro bike for 3 season riding and rock the wozo in snow and mud.

 are fat bikes coming back? either way, that is really cool looking bike.

 Not around here. Everyone I knew that had a Trek or Salsa full suspension fatty sold them. Neither company makes them anymore, and most others that did before don’t either. Lenz is another one that still makes one I think.

 @DHhack: Yeah a FS fat bike is pretty useless for most people. I ride mine on many of the same DH trails I ride in the summer tho. I have a Maxx Huraxdax with 150 mm travel up front and 135 rear. It also has 197 rear spacing. That's the big reason I went with it over the Mutz.

 Fat bikes are huge in Ontario. We get 5-6 months of snow here and almost every cross country ski network also has fatbike specific trails, plus the trail systems local riders build on their own. My work has a rental fleet of about 25 bikes and they're always rented on weekends.

 @Ryan2949: Western NYer here. We’re on fatbikes from November to early April. One local builder here is growler and they tried with a full carbon fan fat bike a few years ago and it was just so heavy that it never really caught on. I ride mine rigid and wouldn’t ride one any other way. That said, the Foes is a really good looking example.

 @Arepiscopo: Growler FS fat bike is just another bike with ICAN04 full fat frame.
I just had my LBS build me a FS fat using ICAN04 frame - it is 33 lbs (Bluto fork).

 They're great in Vermont where the trails are snowed over for 4-5 months a year. I wouldn't ever want to ride one on dirt... though they can be fun on super techy climbs as the grip is crazy. I've got a fatbike, gravel bike, and a FS trail bike in the quiver, and that covers all of our riding seasons!

 Huge in Quebec too! A bit too popular in some area in fact... lol

Two of my friends are looking to buy one but a 2-3-4 years old fatbike is selling the same price as a new one!! You often have a year long waiting for a new one so.... Frown

You need a good amount of snow to have fun on a fatbike but it still a looottt of fun on dirty, on super techy climbs as the grip is crazy, like bonkmasterflex said!! Been fatbiking for 5 years and been on my snowboard 4 or 5 times max, since (used to do 20-25 snowboard days per winter). It is that fun!! Wink

 Warms my soul that Brent is still at it. Got my first LTS back in '93, then became the Northeast sales rep, race helper/mech, and general clingon. And as much as I'll never be caught dead on a Fatbike, this one actually looks great!

 Hey so cool re your Foes history. Hey my Dh bike is a Hydro, with a Fox 49 and wheel up front. Love that bike! I'm thinking of building up a Mixer. But ya a slack short travel Foes is overdue!

 I loved my Mutz, built three, two for me, one for a guy who came into the shop, so much fun, totally steam roll any feature, would love to get another one esp now that geo is modernized.

 150mm travel would mean a fat fork able to stretch to that length. The current Mastadon only goes to 140mm. Makes me wonder if Manitou doesn't have a Mezzer based fat fork in the works?
  • 4 0
 Mastodon Pros go to 150mm, but are only factory configured to 140mm as a max. The owners manual shows how to setup for 150mm.

 There is a guy in new Zealand that supplies the mastodon up to 170mm travel,specifically for the Mutz.

 Seems they engineered that BB tube junction to be just large enough to prevent a water bottle from fitting, resulting in that *interesting* placement that prevents your saddle from dropping fully down.
