Need more of a challenge? Toggle between 8 resistance levels for combined air and magnetic resistance (AirPlus Technology). The harder you push, pull and pedal, the more air you’re moving and the greater the resistance. There are many benefits of including AirPlus resistance in a standard air bike as it allows athletes to train for strength, cardiovascular and multiple combinations between the two. Users can better achieve specific goals (i.e. general heath improvements, weight loss, muscle tone) due to the wide range of resistance provided by the added magnetic resistance (AirPlus Tech) as well as the natural resistance from the flywheel as you increase RPMs. Additionally, this equipment allows users to gradually increase the intensity of their workout as they progress in their fitness journey.
