Crestone

$4,950 to $6,050

$4,950 to $6,050

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.

Echo

$2,999 to $5,850

$2,999 to $5,850

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

Flume

Starting at $2,199

Starting at $2,199

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.
