SmartHalo 2 Bike Computer

The original SmartHalo was heralded by some as the best biking accessory since the wheel. The SmartHalo 2 is even better. Like its predecessor, it has a circle of colorful lights it uses to communicate information, but it's now joined by a white-pixeled "PeekDisplay" that enables more robust features. It can supply turn-by-turn navigation, display the fitness metrics for your ride (which also sync back to your favorite fitness tracking app), protect your bike with a 100 dB alarm, and keep you safe at night with a 250 lumen light. It's also waterproof, goes weeks between charges, and can easily be customized to show the information that's most important to you.
