The M3i Air is Keiser’s pioneering, third-generation, indoor cycle – the result of over a decade of manufacturing experience and research, and developed in conjunction with the cooperation and feedback of trainers and facilities worldwide. By utilizing a revolutionary new magnetic resistance system, the M3i Air delivers a superior ride which feels just like an actual road bike.


  • Iso-Lateral® Technology – Iso-Lateral® technology delivers the smoothest converging and diverging arcs of motion in the industry. This allows your members to move both limbs at the same time, one at a time, alternating, or with different weights for each.
  • Independent Limb Movement – Dual selectorized weight stacks preserve the integrity of independent arm or leg action, allow users to obtain more proportionate results, and add more strength-training variety to workouts.
  • Superior Belt-Drive System – Short, direct transmission of resistance through a belt-drive system ensures smooth performance and premium durability.
