Fat bikes are becoming fixtures on groomed multi-use trails throughout Colorado, and many Nordic centers and ski resorts are now allowing them on their trails. Some areas are even hosting competitive races — Como puts on the annual 20-mile Abominable Winter Fat Bike Race; Crested Butte, always ready to adopt biking innovations, is home to the Alley Loop Fat Bike Race; Sunlight Mountain Resort in Glenwood Springs and Copper Mountain both host races and rides guided by moon and bike lights; the Cloud City Wheelers bicyling club in Leadville coordinates its Winter Mountain Bike Race Series throughout the snowy season; and the 10-hour Silverton Whiteout race debuted in 2015. (Many events are in January; check our events page for details.)

The comically wide tires bring back memories of clunky first-generation mountain bikes, when weight and agility weren’t main priorities. With fatter tires and handlebars and not-kidding-around treads, these new bikes aren’t speedy, but they can go just about anywhere, floating on the snow and giving people of all skill levels a new mode of exploration. Many ski areas offer lessons with staff instructors; the bikes’ three-point stance and low center of gravity make it an easy activity to pick up.

Ski Bike Down the Slopes

Ski biking (sometimes called snow biking) is another way to experience the beauty of a Colorado winter and also get your adrenaline flowing. It’s simply a bike with the wheels replaced by skis. Many ski areas offer lessons with staff instructors; the bikes’ three-point stance and low center of gravity make it an easy activity to pick up.
