Error 30 indicates a communication issue between the display of your bike and the internal controller. Somehow, the two aren't communicating properly. Typically the issue is:

  • 40% Internal Controller.
  • 35% Display settings or damage of the display wire connecting to the controller.
  • 20% Motor or a damaged cable.
  • 5% Damage to another wire or the PAS sensor or Throttle. If an issue persists disconnect each separately and test the other. 

First, try resetting your display to default. This is done from the main screen by holding the middle (Power) and top (+) button on your display at the same time. Select reset to default 'yes' and hold the middle button to enter that setting. These steps can be reviewed in our display tutorials:

  4. Is it intermittent sometimes not happening at all during your ride?
