How to Change Region Ninebot ESX

January 13th, 2021


Region locks are one way that Ninebot ESX (ES1, ES2, ES3, or ES4) scooters can be speed limited.

This is similar to the process used for a Ninebot Max/G30.

Often the max speed is set through a serial number prefix.

In order to change your vehicle’s region and unlock its max speed, change the 4th digit of your serial number.

Below is a list of serial prefixes and their effect on max speed.

Choose the one corresponding to the region you want.

    • B is limited to 23 kmh/14.3 mph
    • K is limited to 25 kmh/15.5 mph
    • S is limited to 30 kmh/18.6 mph
    • T is limited to 30 kmh/18.6 mph
    • U is limited to 22 kmh/13.7 mph

Windows

On Windows, there are two main apps that can easily be used to change the Serial prefix.

Ninebot IAP and Ninebot Flasher are based on similar code-bases but have different GUI’s.

Ninebot IAP makes it a little easier to change a serial due to its one-click buttons for changing SN.

Both applications require your computer to have BLE support unless you are using serial for IAP.

Ninebot IAP is an app developed by Scooterhacking.org.

Next, press “Change SN” and type your serial number out exactly as it was before, but change the 4th digit to the prefix you chose above.

Press “OK”, then you should hear your scooter beep twice in quick succession.

The developer has made a 15-30s wait time and an ad that you must watch in order to change the region.

Once you have sat through that and likely decided to use another app in the future, you will hear the scooter beep twice indicating a successful region change.
