Borealis is a Colorado Springs, Colorado based company that specializes in building fat tire bicycle frames and components. What differentiates them from other bike companies is that they ONLY do fat bikes, and they do them really well. They offer both aluminum and carbon fiber models with several component and wheel options available, so you can get exactly the bike you are looking for. The crew at Borealis love the sport of fat biking and show that love by putting on the Fat Bike Worlds race each year. We have really enjoyed working with this company and the bikes they produce are high quality. Check out what we have in stock below or stop in for a test ride!
