The first thing you should do is make sure you have the latest version of the Gotrax app installed on your smartphone. Next, open up your app and head to the Settings section (the gear icon at the top of the screen). Look for an option called "Modify Vehicle" and tap on that. Once you're in there, tap on "Remove Speed Limiter." That will put your scooter into programming mode, where you'll change the mode according to your style and needs.
