The LifeBEAM bicycling helmet has an all weather compatible “advanced optical” sensor in the helmet to collect data on your heart rate, calories and performance. But the best thing about this helmet is that you are not tied down to communicating that data to only one device or app. This helmet will transmit the data via Bluetooth 4.0 or ANT+ to your phone, fitness watch or cycling computer devices, like those from Garmin, Suunto, Timex, Adidas, Mio Technology, PapaGo, etc. (see complete list here) and apps like Endomondo Sports Tracker, iRunner, iBiker, iCardio, Map My Ride, Samsung S Health, and Garmin Fit. To connect to your phone you will need an iPhone 4S or newer or an Android phone running 4.3 or later. It sells for $229 from LifeBEAM’s website. Pilots, astronauts, and special forces were LifeBEAM’s first clients using their biosensors. So, if they’ve successfully used LifeBEAM’s biosensors in extreme environments, I suppose it should also work for us common folk.
