There are several riding modes that you can use for your KQi scooter.

The 4 modes are E-Save / Sport / Custom / Pedestrian.

You can find this in your user manual.

After a long press of the power button to turn on (or off) the device, short press once for the gear switch.

Attached is the video of how you can switch to different riding modes.

E-save mode has a riding speed of up to 15 km/h for your KQi kick scooter.

You will need to bind your scooter to the app and activate it by completing the tutorial. 

Only after this that you can switch to sport mode and get the maximum speed of your kick scooter.

In case you're unable to proceed with the tutorial, please update the NIU app to the latest version. Then check if this helps resolve the problem. If this doesn't work, please send an email to questions@niu.com and include the scooter's SN or VIN, screenshot of the App version, and the video recording of your NIU App and scooter showing the problem so we can check.
