THE POWER IN HUMAN PERFORMANCE
Keiser M3 Indoor Cycle Resistance Design
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 began more than 30 years ago in the training of world class athletes. Keiser began in sport because they recognized that there are two components to any human movement; 1. The force you produce, and 2. The speed at which you produce it.


The M Series Computer displays
- 1 - Backlight Sensor - The Backlight Sensor automatically detects ambient light levels in the room and turns on the Backlit Display when needed.
2 - Cadence (RPM)
3 - Power Output (Watts/Kcal)
4 - Heart Rate (HR)
5 - Elapsed Time
6 - Current Gear (Resistance Level)
7 - Odometer / Trip Distance
The Computer gives accurate and precise information instantly, and automatically. It will also display average ride calculations and total distance that has been put on the machine. The Trip Distance feature was initially intended to be used by gyms and facilities to record how much an M3 was used for a given time frame. The odometer does not reflect distance in terms of miles or kilometers, rather something in between. For every 200 turns of the crank arm the distance will reflect as 1.0 on the display. In the future, we may revise the computer's algorithm to display a more recognizable distance, which will also be influenced by a rider's pedaling effort or Power.
