You may wonder why you are still stuck in e-save mode even after binding and activating your kick scooter to the app.
When you see the e-save indicator flashing on your scooter's screen and you can't switch gears, it means that your scooter is in custom mode. If you manually set a top speed in the NIU app, it will blink the E-Save on the scooter.
You will need to enter the NIU App and turn off custom mode. Only then can you switch gears and use the sport mode for your kick scooter.
