Just assembled my new M3i Bike and the computer is not working.
Problem: Computer not turning on when pedaling.
Solution: Check the wire that plugs into the circuit board. Typically it gets disconnected if tugged when mounting the computer.
Remove the top 2 top corner screws located on the bottom side on the computer.
This will allow you to remove the face cover and give you access to the LED / display.
Look behind the display and find the 4 pin wire connector (red/black/green/yellow) and align the holes on the connector to the pins on the display and squeeze it closed with your thumb and index finger.
