The Navitas Speed Controller allows you to adjust the Speed, Regenerative Braking, and Acceleration.

Once it's dialed into your desired settings, you can use the OTF key to lock it to that speed. Useful for when your kids are driving it!

There is also an app called the Navitas Dashboard where you can adjust over 100 other settings. You can even lock your cart from the app. This makes locks and cables obsolete!
