Here is a cycling backpack designed to help you stay out of trouble on the road. The Roadwarez Street Warrior Bluetooth-Enabled Cycling Backpack displays turn signals on your back. It features automatic hands-free signaling with voice control.
The GPS router automatically signals for you. In case of an accident, the motion sensors alert the app, so a SMS message with your location is sent to your friends. The battery lasts up to 10 hours.
