Are you trying to increase your speed? Otherwise, there a USB port/connection cable that you can purchase to connect directly to your bike. You have to disconnect the screen on your bike and connect the cable to the cable that is connected to the motor. You will be prompted to download the software. Once in you will see all the parameters of your motor.
Take a screenshot of the settings before you do anything. This will ensure you can reset everything if you don't like the changes you made. This will void your warranty. It's a diagnostic tool that allows shops to customize the settings to their settings. Personally, I've never felt the need to change my Rad bikes settings, but when converting bikes to electric, it's handy.
