HomeReviewsRide a mountain… on a Ski Bike! This is the Lenz Sport Ski-Bike. It’s exactly what the name says… a bike on skis. The Colorado based company has a few different models tricked out for the snow. The Ski Bike is perfect for those lacking in the coordination to tackle a mountain on traditional skis or snowboards. Judging from the videos… these things handle well allowing riders to scream down a mountain with a more familiar control.
