Often, on a Ninebot ES1, ES2, ES3, or ES4, Error 18 is due to the controller failing to retrieve proper values from the hall sensors.

This can be caused by the motor hall sensor cable (the 2 x 3 connector) coming loose or getting burned.

Occasionally this can also occur if the sensors themselves are burned or damaged.


Reseat the motor hall connector and restart the scooter.

Make sure the plug is firmly in place before reassembling.

If reseating doesn't work then attempt to plug the motor into another controller and see if some part of the old controller is burned out.

If no other steps work, you may need to follow the guide at: Replace Ninebot ESX Motor.
