Our ANGi sensor (patented in the USA) 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.
