This allows the user to get a great work-out, as powerful of one as they want. The Airdyne also supports heart-rate monitoring, which allows the user to continually monitor their pulse. This lets them tell if they need to pedal faster or slower, depending on whether they think their heart rate is too fast or too slow. When compared to another exercise bike by Schwinn, the Airdyne Evolution Comp, the Airdyne falls short in some areas, such as resistance based braking, or sealed cartridge bearings.
