TRACK EVERY RIDE. RECORD EVERY DETAIL.
There’s an easy way to see your progress when training on the Keiser M3i Indoor Bike.
The FREE Keiser M Series app enables you to track every ride and record every detail of your cardio workouts, as well as:
• Train using Functional Threshold Power (FTP)
• Access guided sessions developed by Keiser Master Trainers
• Analyze ride data within the app itself
• Export ride data in TCX format for analysis by other tools
IT’S EASY TO GET IN SYNC.
Syncing your M3i with the M Series app is easy. Simply find your Bike ID number, which appears on the second line on the right-hand side of the M3i display for three to five seconds when you being pedaling.
Unlike other bikes, the Bluetooth®-enabled M3i with open API is able to communicate with group class projection systems while SIMULTANEOUSLY syncing data to the M Series app and other cycling apps.
DOWNLOAD & RIDE.
Simply search the App Store® or Google Play™ to download the Keiser M Series app for Apple® or
Android™ device and start riding.
While the M Series Computer is awake, the Backlight Sensor automatically detects ambient light levels in the room and turns on the backlit display when needed.
The M Series Computer is a powerful teaching and programming tool. It can assist both the instructor and the participant by providing immediate feedback as well as the ability to track on-going improvement. The computer can be used as a motivating tool to engage participants in their workouts, as the more participants understand the components of a proper workout, the further they can fine tune their performance.
The M Series Computer displays:
1 – Backlight Sensor
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 M Series 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.
EDY CURRENT RESISTANCE
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 decrease
M SERIES BIKE PEDAL
With our game-changing bike pedal, Keiser has again revolutionized indoor cycling down to the last detail. New pedal features include:
- Stronger bearings tested for static and dynamic loads
- Cage integrated into pedal design, not just added on
- Ramped barbs for secure and simple foot placement
- Curvature eliminating pressure points on the rider’s foot
