If you live in the city your bike can be a great way to get to and from work — you save money on gas while helping stay in shape — but there are plenty of hazards out there for bike commuters. The Helios Bike Bars ($200) make your two-wheeled transportation safer and smarter, thanks to built-in intelligent LEDs and GPS. The LEDs, including a powerful headlight and rear-facing indicators, light your path and signal to others your intended turning direction and speed. On-board GPS gives you turn-by-turn directions and lets you find your bike if it's lost or stolen. Bluetooth 4.0 connectivity lets you use your phone to control ambient lighting, navigation, and more. Choose from two versions, the bullhorn and the drop bar, both available in black and white.
