Our patented ANGi sensor calls for help when you can’t. In fact, it’s the first device to protect you before, during, and after a crash. It does this through a pairing with our Specialized Ride App for iOS or Android devices. And if it detects a crash, it commences a countdown that, if you’re ok, you can stop and keep riding. If, however, ANGi determines that you’re in need of help, it’ll send an alert to your selected contacts with your last known GPS coordinates and a message that you’re in need of help. What about if you’re out of service coverage? ANGi has a plan for that. Just set your estimated ride time before you head out when you know that your ride will take you out of range. All you need is an active data signal when you start your session. And if you haven’t completed your ride within that time frame, ANGi will send a notification to your contacts with your last uploaded location.
- ANGi is a ride tracker, crash detector, and safety beacon.
- Includes a one-year subscription to Specialized Ride Premium app.
- Detects and reports potentially dangerous helmet impacts to the Specialized Ride app, which notifies your emergency contacts and sends them your most recent GPS coordinates.
- Additional premium features include start ride notifications and ride-time alerts.
- Attaches to Specialized ANGi-ready helmets.
- Approximate six months' battery life on a 2032 coin cell battery.
- Weight: 10 grams w/ battery
- Two-year sensor warranty
