This unique speedometer uses a GPS for speed tracking, and displays your speed with an RGB LED. While as-programmed the speed is displayed only as stopped (red), +2MPH (yellow), +9MPH (blue), or +13MPH (green), this could be expanded to a more granular form if you so desire. Also, the GPS unit could be used to show other stats, like how far you are from home, and the bike has a white flashing mode specifically for night visibility.
