To see all the articles, head over to our Winter Guide Hub Page and be sure to check out part 1 and part 2 of our Hottest Fat Bikes Round-Up.

Fatback Corvus

Fatback Corvus

The Fatback Corvus is the brainchild of fat bike original gangster Greg Matyas from Alaska. The frame is unidirectional carbon fiber creation with room for up to 4.8” tires. The 460mm keep the bike stable, but not sluggish. Other highlights include a SRAM GX1 drivetrain and Avid BB7 mechanical brakes. If you want to spend more, the model range rises up to $6675, and includes such enticing add-ons as a Lauf suspension and Schwalbe Jumbo Jims 4.8” tires. Head tube angle on all the bikes is 69.5, maintaining a responsive and maneuverable feel. | Price: $2975 | More info at fatbackbikes.com

KHS 4 Season 5000

KHS 4 Season 5000

The 4 Season 5000 gets top-of-the-line spec at a price where some brands are just getting started. Frame and fork are carbon fiber with internal cable routing. The 2×10 drivetrain means you’ll never run out of gear. Girthy 4.8” tires float in sand and snow. Head angle is nimble 68.5 degree, with a fairly steep seat angle of 73.5. Chainstays are a lengthy 462mm to improve stability and provide ample tire clearance. Finished in matte black with no decals, this bike is a stealthy looker. Thick, shaped carbon frame tubes deliver a stiff but light frame ready to take on year round riding. And there are five models to suit just about any budget. | Price: $3299 | More info at khsbicycles.com

Moots 4 Frost Hammer

Moots 4 Frost Hammer

When you’re done trying different bikes, it may be time for a custom Moots. The heart of the bike is its titanium frame. And while $3975 is a steep price, we’re likely talking about a 10-year investment here. Head angle and seat angle are fairly steep at 69 degrees and 74 degrees respectively. And the bike sits low, with a 12.1” BB height. Tire clearance is up to 4.8” and the bike is adaptable to 3.0×29+ for summertime use. Lines on the frame bend and curve to allow for better standover clearance, and it has a 100mm threaded bottom bracket, so there are no creak concerns. Custom options include rack eyelets, dropper post routing, third water bottle location, and an etched and engraved finish. | Price: $3975 | More info at moots.com

Norco Sasquatch

Norco Sasquatch 6.1

This Norco fat bike screams value — and fun. The price is on the lower end of the spectrum, yet the bike includes a 100mm RockShox Bluto. Rigid forks are fun and all, but get going at high speed with a few jumps here and there and you’ll realize that benefits of travel and rebound control on snow. Another notable spec highlight is the inclusion of a higher end 1×11 drivetrain. And the downside of inadequate low gearing is addressed by a 26t Race Face chainring. That may come at the sacrifice of high speed pedaling but Norco decided that it’s outside of the Sasquatch’s domain. Customizable length stems all the way down to 35mm complement the 760mm bar. Norco also sells 24” models for kids and e-bikes for those who want a little uphill assist. | Price: $2575 | More info at www.norco.com

    Suspension on a fat bike with those massive low pressure tires; really? No, really?

  • Michael Banks says:

    Jim, would it be possible to see your data? I am very interested in this not only as a cyclist but as a researcher having worked with very precise measuring instruments in wheelchair push-force requirements for different tire/caster configurations. As you know, friction and rolling resistance are so interesting because of the multifactorial nature that produces them. It would be nice to see some hard data on this well worn topic within wheeled mobility circles. Thanks.

      Here are some professional results… but they only went up to 4.0″ tires. His data matched ours exactly.

      We came to the conclusion that on snow… tubeless 120 tpi tires with just enough air pressure to “Leave a Flat Track” was the lowest rolling resistance possible for a given rider with any given conditions. “Leave a Flat Track” is the principle we have been working with the USFS to gain access to winter trails. It is a win-win for all nordic users… The hard part was getting nordic bikers to let the air out of their tires. Conventional wisdom says more air = lower rolling resistance and that is simply not true when riding on snow.
