Instructions for getting rid of the factory 20MPH (USA) speed limiter on the Turbo Levo. In this video, I used an iPhone with the app "LightBlue Explorer" to communicate with the bike.
This should also work on Android too, if you can find a bluetooth explorer app that allows you to write/read the program files.
Follow the video EXACTLY, step for step (including closing apps between steps). Also, make sure motor is plugged into battery while you do this.
