Criterium Bicycles and the Monument Ride Center offer bikes, gear, and professional instruction to two-wheel devotees and pedal-pumping travelers. The Beginner Mountain/Comfort Bike class covers training basics, including a gear overview and the keys to proper steering, climbing, descending, and stopping on a dime, picking it up, and buying a Chiclet without ever dismounting. The Riding for Fitness and Weight Loss course teaches more-experienced riders efficient, reasonable ways to bike off calories and build strength while still relishing the ride. Because Criterium Bicycles’ instructors compete in mountain-bike racing, track racing, and Ironman Triathlons, they’re fully prepared to answer any questions, be they about gear ratios or keeping top hats atop heads while riding. Groupon holders may also apply the value to one of Criterium's two $90 classes and pay the $30 difference.
