Today, after less than 140km ridden with the Kinsgong S22, the motor started to make an odd sound, which was increased after power demands. I tried to capture it better for warranty purposes, and instead the motor stalled and burned the mainboard.
I suppose something got loose in the motor, either a magnet, the hall sensor or something else critical. Very glad the final failure didn't happen with me on it, or I would have hit the pavement.
I would highly recommend to stop riding immediately your S22 if you hear any bad sound coming from your S22 motor.
