The Gravity Coaster was designed and developed by former Polish Ski Champion, Jan Karpiel, who competed in both the Europa Cup and the World Cup before deciding to enter the adrenaline sport of MTB downhill racing.

After pursuing a degree in mechanical engineering from the University of Utah, Jan founded Karpiel Design and proceeded to develop and produce unique mountain bikes for the next 15 years. Karpiel bikes have been featured in television science programs (Next Step, Extreme Machines), and films (Down, Double Down, New World Disorder 1 &2), and video games (Sony Playstation 2, Downhill Domination).

His interest in speed and design eventually prompted him to create the Karpiel Speed Bike, which he raced to earn the North American Speed Record (107.7 mph). In designing the Gravity Coaster, Jan has combined his passion for skiing and mountain biking into a brand new exciting way to downhill.
