Quick answer

Error 07 on the NIU KQi kick scooters (KQi2, KQi3, KQi3 Max) means “Controller communication fault and verification failure.” Most likely cause: the display, controller and battery have stopped talking to each other properly. Try this first: switch off and restart.

Switch off and restart
Write down the code and when it happens

In plain English

The parts of the scooter share data over a cable through the stem and deck. This code means that link was lost. A restart sometimes clears it. If it stays, support can check the connections.

Step-by-step checklist

Work from the top. Steps go from free and easy to shop jobs. Switch the scooter off before touching any connector. Tick each step as you go. Your progress is saved on this device.

1Switch off and restartFree Turn the scooter off, wait 30 seconds, then turn it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
2Write down the code and when it happensFree Take a photo of the display and note when the code appears: at switch-on, when you set off, on hills, in rain or while charging. Support will ask for this.
3Contact support or a service centerShop job If the code stays after these checks, stop riding and contact the brand's customer support or an authorized service center. Don't open the deck, battery, controller or motor: most scooter batteries and controllers aren't user-serviceable.
