Inspired by the sport of cycling, the BikeErg offers an authentic riding experience that builds power and endurance with every pedal stroke. The BikeErg has the same flywheel and Performance Monitor as the Concept2 RowErg and SkiErg, bringing to cycling the strengths and features we've previously brought to rowing and cross-country skiing. The flywheel uses air resistance to create a smooth, quiet and responsive ride, and the damper is your "gearing," allowing for quick changes to the feel of your ride. PM5 and Device Holder included.
