There are places in this world ordinary bikes can’t take you. And when every ounce counts, when every pedal stroke drives you further into the wild, get there on Borealis Crestone. The lightest and toughest carbon fatbike on the market lets you follow northern lights deep into a Wisconsin winter as part of the 42K Soltice Chase, or pack it up for a blitz across the tundra – the Crestone is the premier choice for fatbiking fun.

As fatbiking differentiates itself, carbon rigs are a way to outdistance your fellow riders – both at the trailhead and when deep in the bush where no trails exist. The Crestone is the elite choice, and it comes in two builds for the riding and spec you prefer. XX is the lights-out, blinged-out best – race-ready and trail-tested; the XO1 maintains the outstanding performance at an attractive price point.

Named after Echo Canyon in Dinosaur National Monument up in the northwestern boonies of Colorado, the echo is the first performance-oriented, full carbon frame designed around the brand new RockShox BLUTO fat bike suspension fork. The extreme lateral stiffness combined with geometry optimized for the BLUTO's 100mm of travel truly revolutionized fat biking. We also spec 35mm clamp stems and handlebars on our top two build kit models; this new oversized standard is a perfect match for the extra-wide tires of fat bikes. Internal dropper seatpost routing is the cherry on top of the echo's design features that make it stand out as a do anything, ride anywhere, year round adventure shredding machine

Fatbiking adventurers know that inspiration matters, and a ride (or bike) is only as good as the idea that created it. The expedition-ready Flume capitalizes on all the sweetness of the Crestone, but does so in lightweight, 6000-series aluminum. Up mountains, down glaciers, and across deserts: the Flume is ready for action.

There are all kinds of alloy fat bikes on the market, but none with the Flume’s purebred heritage. The custom tubeset mates ideal, high-performance geometry with competition-ready spec. But if pedaling across our blue planet is more your speed, the Flume will speed you through.

Wednesday, $1499 Wednesday is a frame with a decade of Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of our other Omniterra bikes can and for the Wednesday, we borrowed elements from both our Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff and doesn’t feel sluggish when you have to ride back to the top.

Ice Cream Truck, $2399 The Ice Cream Truck has the ability to float over pretty much anything you’ll find out there be it snow, rocks, mud, sand, or rocky mud. But unlike our other, more terrain crawling fat bike models, the Ice Cream Truck’s geometry is trail approved and ready to rip. The Ice Cream Truck is made out of our own proprietary 4130 CroMoly steel and is ED coated. ED coating is a process that leaves a coating that, externally, provides a solid foundation for paint while also providing an added layer of corrosion protection internally. However, we still recommend an additional treatment such as Frame Saver or Boeshield. Ice Cream Truck begins to differ from all of our other fat bike models from there.

Pugsley, $1399 Many moons ago we began producing the Pugsley because we wanted to ride a bike that could be ridden where other bikes simply faltered. In order to do that we figured this bicycle needed to have floatation and traction the likes of which have never before been seen. Pugsley is our brilliant solution to this -and it seems to work. This bike rolls through all the sloppiest slop around.

Ice Cream Truck Ops, $1849 Ice Cream Truck Ops is a ‘little brother’ of sorts to the Ice Cream Truck but both share the same Surly 4130 triple butted Cro-Moly Ice Cream Truck frame, which can only mean that you’ve come here looking for a trail-approved ripper that can fit some big ass tires. The Ice Cream Truck Ops uses the same 190mm spaced rear end of the standard Ice Cream Truck. With the Surly MDS dropout system you have the option of running a 197x12 thru-axle, 190mm geared or single speed drive train. The complete Ice Cream Truck Ops comes with only the Shimano direct mount, 197mm thru-axle chips and framesets come with all three MDS chips so you can build the frame up however you want.

Pug Ops, $1699 We won’t beat you over the head re-explaining the idea of the Pugsley or fat bike theory. If you’re looking at this bike there’s a good chance you already know what you’re looking at, and if you don’t then check out the Pugsley and Moonlander pages. There’s plenty of info there to get you up to speed. Pug Ops shares the same frame as the standard Pugsley, and it has the same non-offset fork.

Moonlander Ops, $2550 Many of you are probably familiar with the Moonlander. This was our first bike to run 4.8˝ tires on 100mm rims. Such a large footprint allows you to ride them at very low pressure, which bestows a rider with lots of traction and float over all kinds of terrain. Moonlander, like its name implies, is meant to go beyond where normal bikes, even normal fat bikes, can go. It is designed from the ground up to ride where there are no roads, no trails and no people.

Pugsley SS, $1199 If you’ve ever ridden a singlespeed you probably remember it being the most fun you’ve had on a bike but you may have found it odd how little you thought about the bike while you were riding. It was just you, hauling ass down the trail. It was just you pedaling for all you were worth. There was no noise… no clunky. There was only speed, one speed, only fun. There really isn’t a better frame to give the single speed treatment to than the Pugsley. It’s the same E.D. coated, proprietary Surly 4130 Cro-Moly we all know and love.

Moonlander, $1999 Moonlander runs 4.8˝ tires on 100mm rims. Such a large footprint allows you to ride them at very low pressure, which (as with a snowshoe) enables unparalleled traction and float over all kinds of terrain…wet stuff, roots, rocks, pebbles, gravel, sand, and many types of snow. Moonlander, like its name implies, is meant to go beyond where normal bikes, even normal fat bikes, can go. It is designed from the ground up to ride where there are no roads, no trails and no people.
