Flash uses a combination of Bluetooth and wireless technology to connect with your phone and send you updates on battery and safety alert status, as well as provide GPS location.
In order to set up all of this functionality, the only thing you need to do is pair your phone with your Flash using the Flash app. This allows the two to communicate securely and seamlessly. When you receive your Flash and launch the app on your phone, you'll be walked through the quick and secure pairing process. Once that is complete, you're good to go.
Just enable Bluetooth on your phone whenever you're headed out for a ride, and your phone and Flash will automatically connect. This way, your phone will display your current speed, track your riding distance and time, and more.
Note that in order to simply ride Flash, it's not necessary to have your phone with you or Bluetooth enabled.
In order to maximize our cellular coverage, Flash uses 3G and LTE wireless technology to send you battery status and security alerts, and to track GPS location in the case of theft.
You don't need to do anything to set up a wireless connection. Flash arrives connected and ready to go, and it is completely separate from your own personal wireless account. You don't ever have to deal with it (or pay for it). Just get out and ride!
Due to issues with certifications, regulations and wireless performance, Flash is not designed for wireless use outside of the United States.
