The Evocardio Airbike Renegade pro AB100 is a stationary bike with handles, also known as the fan bike. The large fan creates the resistance, this wind resistance is increased exponentially as you pedal harder. So the intensity is completely dependent on the energy the user puts into the workout. It is possible to train your lower and upper body simultaneously. But you can also train only your arms, by resting your feet on the supports.
