This is so much more than just a bike helmet! One of the latest items of wearable tech, this helmet tracks your heart rate and calories burned, sending the data to your devices via Bluetooth. The heart rate sensor is built into the helmet, so no chest strap! It's designed to be used in any weather, it gives you 15 hours of use, and it even comes with LED lights built in for maximum convenience.
