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.
