Keiser M3i Indoor Cycle


Keiser M Series Indoor Bikes revolutionised the world of group fitness when they came on the market over two decades ago, and have set the standard for the category ever since.

Keiser M3

The first bike to use eddy current magnetic resistance and an aluminium flywheel, the M Series continues to offer users and owners innovations that improve the group cycling experience.


As part of our commitment to scientific solutions for fitness, Keiser M Series Indoor Bikes are built to change the way you look at indoor cycles.

  • Rust-resistant design includes stainless steel hardware and rear flywheel
  • Revolutionary, re-designed Keiser pedal
  • Quiet and low-maintenance belt drive system, eliminating the output of dust and need for lubricant with chain-driven systems
  • Magnetic eddy current system provides infinite levels of resistance options and a smooth ride
  • Lightweight at 85 lbs. and easy to transport with two front transport wheels
  • Over 300,000 M3 field-proven group bikes in use today
  • Powertrain tested for more than 30 million cycles
  • Handlebar tested for more than 30 million cycles


The magnetic resistance system works using eddy currents: electric currents on M Series equipment are generated by two opposing magnets passing over the flywheel. By varying how much of the flywheel comes into contact with the magnetic field, resistance can be increased or decreased for the rider.

And, as no parts in the resistance system ever touch, there is no wear on the system.


As indoor group cycling grows in popularity and the demands on bikes increase, the need for a more user-friendly - yet more durable - commercial grade pedal became clear. For those who demand more from their equipment, Keiser introduces the M Series Bike Pedal.


Because the industry standard isn’t up to our standards, Keiser once again revolutionises Group Cycling down to the last detail with our game-changing Bike Pedal that will challenge the way all pedals are measured.

Keiser M3

  • A. The cage is integrated into the design of the pedal, not just added on
  • B. Ramped barbs allow for secure foot placement without insertion difficulty
  • C. Curvature of the pedal matches typical shoe design, eliminating pressure points on the rider's foot
  • D. Stronger bearings tested for static and dynamic loads experienced when rider gets on, off, and rides the bike
  • E. Pronounced edge allows rider to easily flip pedal and insert foot
  • F. Easily accessible SPD tensioning adjustment
  • G. Flexible and strong axle design that evenly distributes stress load. Forged, chromoly steel axle, machined and heat treated for maximum strength
  • H. Re-angled SPD clip position provides greater clearance between the cage and the ground when using the SPD clips
  • I. Secure strap design to prevent slipping when tightening and excessive wear

Customer Reviews

Just added the Keiser to our home gym. I will be in touch in April with another order, Thank You, Josh
- Josh S on 09/03/2017
The M3i model is a really high quality piece of kit. It is super smooth and magnetic resistance means it is virtually silent. Thanks to the team for phone support setting up the bike. Tested it with a few clients already and they love it.
