The app is not required in order to use your bike. As soon as your Flash is assembled, you can take it out and ride without ever using the Flash app.
However, the app does provide you with some great features, including:
- Setting a personal PIN code for the bike's touchscreen to turn on or disarm your Flash.
- Live check-in on battery, security and location status, no matter where you are.
- Arm/disarm Flash from any location.
- View your live riding data, such as distance and time.
