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 M3i 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 M3i 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.

Keiser M5i Strider

The Keiser M3i 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.
