This app connects to Etwow GT SE and can set settings including unlocking full speed (use on private roads).
Be careful because this app can lock and stop suddenly your scooter while ridding if you press the red lock.
Don't have an Android phone? You can send custom Bluetooth instructions to configure your E-Twow GT Bluetooth (SE / SL / GTS) scooter
