Meet HAIZE: a smart bike navigation device that uses LEDs to show you how to reach your destination. It is very simple to use. Just choose where you would like to go, attach the device to your bike, and rely on the outer and center LEDs to figure out the direction and distance to your destination.
HAIZE has turn-by-turn and compass modes. It can be used on any bike. There is also a wristband that lets you wear the device and take it with you while you are off the bike.[where to find it]
