Concept 2 BikeErg

The Concept2 BikeErg is the latest addition to our family of sport-based ergometers

The BikeErg has a flywheel with fan blades, which cause increasing air resistance as the wheel spins faster and as the damper allows more air to circulate
The resistance you feel on the BikeErg is a function of your cadence
Simply increasing your cadence will also increase the resistance, similar to a road bike. Adjusting airflow to the fan will change the resistance you feel at a given cadence
Airflow is controlled by a simple damper lever on the fan enclosure. The result is much like changing the gearing
