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.


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 M3 COMPUTER 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:

    Backlight Sensor Cadence (RPM) Power Output (Watts/Kcal) Heart Rate (HR) Elapsed Time Current Gear (Resistance Level) 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.
