All Lenz Sport Skibikes are hand made from the ground up, and mountain tested right here in Colorado. We also fabricate our own line of skibike boards that bring ultimate performance for all types of ski biking. We use superior grade, American aluminum for every frame. All of the parts that go into the fabrication of each frame are CNC machined in-house including head tubes, swingarms, pegs, skis, and more. All Lenz Sport ski bikes are light and durable for all types of riding, and the geometry has been developed over years of ski bike riding to give the most performance and comfort of any snow bike in the world.
