LifeBeam bio-sensing bike helmet reads your heart rate and provides calorie burn data, eliminating the need for a conventional wrist-top heart-rate monitor with a chest strap. The same technology appears in LifeBeam ski goggles, hats and visors.
Likes: Invisible, comfortable, convenient. A tiny optical sensor contact is built into the helmet’s headband. It connects to your smartphone via Bluetooth or ANT+. The battery (rated to last up to 15 hours) charges via a USB port in the rear, with a 1.5-inch status light-strip glowing blue when charging or turned on by pressing a hidden button. LifeBeam doesn’t come with its own app; it pairs with Suunto, Polar, Garmin and more, and with numerous iOS and Android apps. The helmet, a modified Lazer Genesis, includes the excellent Rollsys adjustment thumb-wheel for a perfect fit. While not light (about 13.5 ounces, heavier than the regular Genesis by 25%), it feels comfortable.
Dislikes: Another thing to remember to charge. You can’t wear a cap under your helmet. You have to return the helmet to Israel if there are problems. It doesn’t do enough; heart-rate watches are loaded with data this doesn’t have. Why not a built-in LED safety light?
