Kaczmarek formed Borealis Fat Bikes in 2013 by utilizing his track record of successful start-ups to implement operational procedures that drove the Colorado Springs-based company through exponential growth during the first two years. “Fat bikes are the hottest thing on two wheels, and Borealis is thrilled to be a leader in this category.”

Steve is an avid outdoorsman and grew up in the competitive sailing arena where the lightest, fastest designs and products were demanded. After moving to Colorado where large bodies of water are hard to find, Steve identified mountain biking as his preferred activity. Just following Steve’s first Fatbike ride, he was able to combine mountain biking with his extreme understanding of carbon fiber and exotic materials from sailing into what is now recognized as the World Leader in Fatbike Technology.
