Keiser M3iX Indoor Cycle

“These are getting used more than anything else in gyms.”

The M3iX is a newer addition to Keiser’s dynamic line of award winning indoor fitness cycles. Combining the unique pivoting patented X-Bars to the heralded M3i Indoor Cycle makes the M3iX to mountain biking or hill climbing what the M3i is to road biking. It has the same silky smooth ride and M3i reliability, with 7 levels of handlebar resistance. Independent upper and lower body movements offer great core, upper torso, and arm benefits and also aids balance training. Research shows X-bars burn more calories than traditional group exercise bikes. The X-Bars offer added variety for both instructors and riders both in the classroom setting and out on the fitness floor.

The M3iX is made of corrosive resistant materials, has a non wearing resistance system, and is virtually maintenance free. The M3iX is a great performance exercise cycle for all indoor cycling classes and cardiovascular conditioning. The M3iX is like no other cycle you have ever rode before; smooth ride, whisper quiet, easy to use and a host of other built in features designed with your clients, instructors, and facility in mind. The M3iX also comes with a computer that measures RPM, power output in watts, kilocalorie expenditure, heart rate (via wireless Polar monitor), trip time, gear (resistance), and trip distance. Experience a whole new way to cycle, with the Keiser M3iX.

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 revolutionizes Group Cycling down to the last detail with our game-changing Bike Pedal that will challenge the way all pedals are measured.

Indoor Cycling is a group exercise class done on stationary bikes. During the class the instructor simulates a ride. Together, you travel on flat roads, climb hills, sprint and race! It is truly a fantastic cardiovascular class. The beauty of indoor cycling is that you can do it even when its raining or snowing outside! You are kept motivated by the instructor, the people around you and by the music! Its lots of fun. FitnessZone® is the premier fitness superstore on the Internet for indoor group cycles. We carry a wide selection of top quality and reliable home or commercial indoor group cycles. The FitnessZone® superstore offers the largest selection of indoor cycling bikes in the industry. Since 1987, the evolution of the indoor group cycle has come a long way; and is still an ever-growing popular way for an intense, cardiovascular exercise in the home or at a group cycling class. We offer such a huge selection of indoor group cycles at the best prices so you don’t have to waste time searching for a lower price.



An eddy current is an electric current in a conducting material that results from induction by a moving or varying magnetic field. On M Series equipment this is generated by two opposing magnets passing over the flywheel. The flywheel (a conductor) passes through the magnetic field generated by the two powerful magnets. By varying how much of the flywheel comes into contact with the magnetic field you can increase or decrease the amount of resistance for the rider. As no parts in the resistance system ever touch there is no wear on the system.

When the flywheel is turned in proximity of the magnetic field the eddy current is created. The flywheel acts like a conductor with closed circuits. The energy generated by turning the flywheel has nowhere to go, so as it resists it becomes more difficult for the rider to pedal. If the flywheel is in less contact with the magnetic field it’s easier to ride. The more of the flywheel that comes in contact with the magnetic field (the higher the energy that is being generated with each turn) the more difficult it becomes to ride.

Fig. 1. At full resistance the flywheel is in most contact with the magnetic field. When you reduce the amount of contact to the field (move the magnets away) the resistance then decreases.





Keiser M3iX Console Features:

LINE 1 BACKLIGHT SENSOR: While the M Series Computer is awake, the Backlight ensor automatically detects ambient light levels in the room and turns on the backlit display when needed.

LINE 2 RPM (CADENCE): The RPM displays the cyclists Revolutions Per Minute on one crank arm. RPM is also known in the cycling world as Cadence and is roughly the speed at which the cyclist is pedaling. At above 140 RPM the computer will not read and the word “STOP” will appear to indicate that the cyclist is pedaling faster than he or she needs to be. If the cyclist is out of the saddle and wishes to retain the sufficient resistance, pedaling should not fall below 60 RPM.

LINE 3 POWER: The Power Output is displayed in Watts (currently generating) and Kilocalories (total value for the workout). The computer toggles back and forth between Watts (displayed for eight seconds) and Kilocalories (displayed for two seconds) throughout the ride. Rated accuracy for Power is +5W for Power below 50W, and +10% for Power above 50W.

LINE 4 HEART RATE: If there is no Heart Rate signal, a steady heart symbol and a zero will be displayed. If a participant is wearing a Heart Rate strap, once the computer locks onto the signal, the heart symbol will blink and display the heart rate. Please note that the Heart Rate strap.

LINE 5 ELAPSED TIME: The number shown reports the total time spent cycling and will reset to zero after 60 seconds of inactivity or if computer is reset using the gear shifter.

LINE 6 GEAR: Gears from 1 – 24 are displayed on the bottom left hand of the screen.

LINE 7 ODOMETER/TRIP DISTANCE: For the first eight seconds when the computer is first activated, the Odometer will display the total distance the cycle has been ridden. This feature is for service and maintenance purposes only. After eight seconds, the Odometer will display Trip Distance.


Display console design

Although it may look similar to the console used on the earlier M3, the Keiser M3iX display console has one major difference; its Bluetooth wireless connectivity.

The screen itself is backlit, and can still be used to provide feedback on a number of important workout statistics while you cycle.

This includes your RPM, power output in watts, heart rate, time, gear (1-24 gears), and distance.

Bluetooth connectivity to phones and tablets

With the increase in the number of mobile fitness apps and personal fitness trackers, it’s becoming more important to be able to track your workout away from the display console that’s attached to the machine.

The Keiser M3iX can now connect to your phone and sync the data from your workout, which acts as a more accurate way to measure your progress between multiple workouts.

While this is a feature best suited to single users for their home gyms, it can also be a major benefit for commercial gyms and group cycling sessions.

This is because each bike can be synced to a projector, which can then display your workout information on a screen in front of you.

Having the entire cycling group’s workout stats displayed in one easy-to-read format can help create a greater sense of competition, encouraging you to push yourself more and see greater improvements in your fitness as a result.
