Fat Bike Buying Guide (and Best Entry-Level models)

Fat biking (or fat tire biking) was invented, you could say, in Alaska back in the late 1900s, but it really started to become popular in the early 2000s.  Since then, the number of fat bikes you see on the trails, even when the weather is just fine, has really grown.

Fat bikes give cyclists a way to get outside and ride in terrain that would stop most other bikes in their tracks, including most mountain bikes.  Fat tire bikes have been known to cruise for miles on a frozen lake, a sandy beach, or along a rural bike trail that might not be cleared for weeks. No problem if you are on a fat bike.

For many Northerners, the fat bike is an alternative to moving indoors and mounting your road bike on an indoor bike trainer.  Bike trainers are great, and there is an important place for them (I will probably hop on mine in about an hour!), but we talk to many diehard cyclists who swear that they would rather ride outdoors whatever the weather. We can’t blame them.

Today, cyclists from the original fat bike diehards to committed road riders and commuters enjoy fat biking. The right fat bike with the right tires can expand the riding season by months in some places, and good quality fat bikes compete on price with some high-end indoor training solutions.  Not only are fat bikes popular with the cold weather set, but they are also catching-on for beach and desert bike riders because of their proficiency on sand.fat bike best

How is a Fat Bike Different?

Fat bikes and mountain bikes share some designs and components, but some unique features are unmistakably fat bike, including:

  • Wider tires. The hallmark of any fat bike, fat bike tires have grown over the years, from around 4 inches wide to a whopping 5 inches in some cases. In comparison, mountain bike tires now range from 2 to 3 inches. Many road bikes sport tires of less than 1 inch!
  • Fat-specific frames.  Frames and forks need space for huge rubber, and anything else in the way is moved too: fat bike wheels are wider at the axle and even the pedals on fat bikes can be further apart than other bikes.  So, it is not as simple as slapping wide wheels on that mountain bike you have in your garage — the frame design is fundamentally different.
  • Wider wheels (and other components). Wider tires need a wider rim for the whole wheel and tire to stay hooked together. Wheels with wide rims must be wider still in the center, with a wide hub and axle to cut down on flex.
  • Much Lower Tire Pressure. Tire retention is especially important with low tire pressures in mind, and no tire rides as soft as a fat bike tire. This gives the rider more grip and an ability to really “float” along in snow or sand. The high grip creates more drag or rolling resistance on pavement, so fat bikes are unlikely to replace your time trial bike or summer commuter.

What to Look for in an Entry-Level Fat Tire Bike

If you are looking for a fat bike, you will want to search for many of the same things you would in your other bikes. The differences involved can be intimidating at first, but this guide makes choosing a new fat bike quick and easy.

Frame

Like today’s common road or mountain bikes, fat tire bikes can be made of aluminum or carbon fiber for light weight and strength. Some fat bikes are steel for maximum longevity at the expense of weight. Even the highest performance fat bike frame is designed for some durability and versatility, while utilitarian models support huge loads on racks or in bags. As with almost any bike, lightweight frames can make for a quick, responsive feel. However, performance comes with a cost, and components such as wheels and tires are a big part of overall weight. Fat bike frames are also specific to one of two wheel sizes, 26” or 27.5”. The difference in wheel sizes is small in practice, but newer 27.5” bikes may hold more value in the short term.

Tires

We did a whole guide on fat bike tires, so check it out if you wanted a deep-dive. 

Tires are easy to change out if you need new ones, but the amount of rubber involved means the right tires on a bike could save hundreds of dollars. Much like our advice on gravel bikes, match the tire aggressiveness to the type of riding you need to do.  Fat bike tires inherently have quite a bit of tread and tend to be a bit knobby.  Go with a plenty knobby tire if you think your riding will fat bike tireinvolve soft surfaces like loose snow, dirt or mud. Width of the tires is an important factor as well, ranging from less than 4 inches on the low end to more than 5 inches on the high end. Generally speaking, narrower tires are better for riding on hardpacked snow or terrain where you know the surface will at least be solid.  If you run the risk of sinking into snow or sand, go with a wider tire that can be ridden at quite low PSI. Many fat bike riders will ride “tubeless,” removing the fragile inner tube from their tires and replacing it with a combination of tape and liquid tire sealant to use lower pressures. Both systems have ups and downs, but a factory tubeless bike can save time and money for tubeless fans while easily accepting a tube.

Suspension

Some fat bikes have suspension, others don’t.  Having the right suspension can be important depending on the type of terrain you plan on riding your bike. If you are riding steep and challenging trails with features like rock gardens or large ruts, then suspension will help keep the bike under control and the ride comfortable. Rear suspension is rare in fat bikes, but suspension forks are increasingly common. Suspension adds up-front and maintenance costs to any bike, but gritty and slushy winter conditions make fat bike fork and shock maintenance particularly important. Rigid forks are the most popular choice for fat bikers, since the large tires give enough cushion for comfort on most surfaces.

Where to Find a Fat Bike?

There are really three options for buying your fat bike:  New – local, New – large retailer, or used. 

Choosing a second hand bike could shave 50% or more off the cost of a fat bike, but there is plenty of risk involved. Frame damage is the biggest danger, so look carefully for corrosion, cracks or dents. Less critical issues can still cause headaches, and test riding is a good idea, but even an experienced mechanic could miss some expensive issues on the horizon. Fat tire bikes experience particularly hard miles and accelerated wear in particularly hard-to-see places.

Buying a new bike avoids all these risks, so we recommend most first-time shoppers consult a professional.  A local bike shop is always a good place to begin, and we love when our readers support their important local bike shops.  These shops keep the cycling industry going.  There is a chance that your local bike shop doesn’t carry fat bikes, and you will likely need to buy the lines they carry.  But they probably carry those lines because they believe in them!

You can also buy from a larger retailer, or chain.  This can be a good option if you know pretty much what you want, and if your local bike shop doesn’t really carry the fat bike that you have zeroed-in on.  Where possible, we provide some ideas for you as we outline our favorite entry-level fat bikes on the market today.

Our Picks: The Best Entry-Level and Mid-Range Fat Tire Bikes 

Before we get in to our picks, a note.  Just because these bikes are “entry-level” doesn’t mean they are cheap.  Several of these fat tire bikes cost as much as a road bike or good gravel bike.  We wanted to pick bikes that were accessible to many, but that also earn the distinction of being best-in-class.  Sorry, no sub-$1,000 bikes here, but you can always look for good used ones, here.

Trek Farley 5

Find Here.

Trek made a large and controversial splash into the fat bike market with its Farley line of fat tire bikes. Family of the late comedian Chris Farley filed suit in 2017, alleging infringement, and the matter was settled out of court. Legal issues and questions of taste aside, the Trek Farley speaks for itself as a leader among “big three” fat bikes.best trek fat bike

The Farley 5’s MSRP is a little higher than the Giant Yukon 2, and a little on the high side for lowest model in the range but with plenty of modern features. Trek kept the Farley simple with only water bottle mounts, which may restrict some adventures. However, the sleek aluminum frame and carbon fiber fork keep the weight low for a claimed 32.33 lbs in size M. While L and XL models feature a full 4.5” tire front and rear, the Trek website and buyer reports are unclear if S and M rear tires run 4.5” or 3.8”. Any question should be easy for a Trek dealer to answer definitively. Tire knobs are substantial in either size, and tires are listed as tubeless and studdable.

Hits:

  • 27.5” wheel size
  • Studdable tires
  • Good geometry
  • Carbon fiber fork
  • Dropper seatpost

Misses:

  • Limited versatility
  • Potential 3.8” maximum tire on S/M

Worth an upgrade?

The Farley 7’s MSRP is more like $2,500 (here), with changes including a different drivetrain and a suspension fork with 80mm of air-sprung travel. With a retail value over $600, the suspension fork alone helps justify the $800 difference. That makes the upgrade worth the cost for any Farley rider with suspension in their future.

Surly Ice Cream Truck

Find here.

Long synonymous with “fat bike,” Minnesota-based Surly might be the biggest small brand in cycling. Surly is one of several brands owned and operated by Quality Bicycle Products, the largest distributor in the United States for everything except bikes. Surly is widely considered both a pioneer of the fat bike concept and the first to make it rideable in practice. The Ice Cream Truck is a staple of Surly’s fat bike lineup and highly sought after in their home state.best fat bike entry

Surly’s Ice Cream Truck may raise eyebrows with its price of around $2,00 for a heavy steel construction, limited dealer network, crass webpage and lack of suspension or dropper post. Some of that price is justified by the riding experience, with some of the best handling on or off-road of any fat bike, only recently matched by some competitors. The Surly’s steel frame is favored by some riders for its many mounting points and heavy-duty load carrying ability. Surly’s “ICT” does feature the highest quality drivetrain and the largest tire clearance on this list, albeit using the 26” wheel size now dropped by some brands. Tires are Surly’s own with large, aggressive knobs. Overall, the ICT is a poor value for some riders but the only game in town for others. Surly owners can expect better than average resale value due to the brand’s status and infrequent model year changes.

Hits:

  • Huge 5” tire clearance
  • Tubeless tires
  • Great geometry
  • High quality drivetrain
  • Highly versatile

Misses:

  • Price
  • 26” wheels
  • Heavy frame

Worth an upgrade?

Surly only offers one ICT configuration. However, the ICT is Surly’s top model to the Wednesday. The Wednesday shares the ICT’s disadvantages with 26” wheels and a heavy frame, but loses out on tire clearance and premium drivetrain, making the ICT well worth the upgrade. Keep the Wednesday in mind, especially if shopping used.

Giant Yukon 2

True to its name, Giant is a major name in cycling internationally. Alongside Specialized and Trek, Giant makes up the “big three” brands which dominate bike shop inventory in the United States. All three now offer a range of fat tire bikes refined through multiple generations, putting fat tires firmly in the mainstream. Giant is known for its in-house manufacturing and refined designs, which show in its single fat bike model, the Yukon.giant best fat tire bike

Not inexpensive, the base Yukon 2 retails for a little over $1,500, undiscounted. The Yukon’s frame design and angles show a trail focus, with a tucked-in front end and plenty of space to move around with the top tube sitting low and out of the way. That front end features a carbon fiber fork for weight savings, while the rest of the frame uses Giant’s signature aluminum construction. Mounting points include the usual water bottle bosses but little else. The fork does provide additional points, but its carbon fiber construction may not suit heavy loads. Giant does not provide an overall weight, but relatively low-profile tire knobs should help the Yukon’s pace, and at least 4.5” of clearance offers plenty of options.

Hits:

  • Competitive price for what you get
  • 27.5” wheel size
  • Great geometry
  • Carbon fiber fork

Misses:

  • No available suspension

Worth an upgrade?

The Yukon 1 retails for a little over $2,000. This near $500 upgrade changes the drivetrain and brakes, and adds a dropper seatpost. The frame and wheels appear unchanged, while the drivetrain and brakes are an incremental change. A dropper seatpost is handy but affordable and easy to install. We say pass.

Conclusion

With major manufacturers firmly stuck in to the fat bike market, the sub-$2000 entry-level offers better value and more “dialed-in” performance than ever before. We particularly recommend that shoppers looking for value try a Giant dealer with the Yukon 2 in stock. For riders planning to hit the trails, the extra jump to a Trek Farley is worth the money in either the rigid Farley 5 or the suspension fork Farley 7. And for the adventurer, Surly is still the last word in the biggest tires.
