An incapacitating crash that leaves you unable to summon help is a frightening risk for any cyclist. Stick Specialized’s ANGI on your helmet, pair it with your phone, and help is one text message away. If the gadget’s accelerometer and gyroscope detect an impact or spill, it sounds an alarm. Fail to respond within 90 seconds, and the Specialized app sends your location to an emergency contact. The device weighs just less than 1 ounce, works with virtually any lid, and doesn’t require a subscription or annual fee.
