At Borealis, we craft world-class carbon fiber fatbikes. It’s our passion and we do it well, testing our creations in the Colorado backcountry, and venturing to Utah and Alaska and all points in between. Choose from our flagship, class-leading Crestone, the alloy Flume. Based on the tech found on Crestone, and the two carbon rigs that started it all: the Echo and Yampa. Each is different, each is wickedly fast, and each features perfectly dialed geometry for steering precision, stability, and goat-like climbing traits.

CRESTONE

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.

ECHO

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.

FLUME

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.
