This is a possible fix to your exercise bike or elliptical's resistance motor that isn't working especially for a NordicTrack s15i or s22i bike. Most of the forums online have people noting that it is simple, you just replace the resistance motor. I am here to say that may be only one way of several ways to fix the problem. With the use of some batteries and wires you may be able to just re-adjust your resistance motor back into a position that it can sense therefore allowing the control board to send the motor electricity, if that makes sense. Be safe and I'm hoping this helps!
