Sharing the road with cars, as a cyclist, is always a risky proposition. Especially at night. There are many products out there meant to increase your visibility, but none quite as cool as the Revolights. They’re a set of LED lights arranged around a hoop that attaches to the front and back wheels of your bike. Sensors detect the speed at which you’re traveling and the LEDs blink on only when they’re passing through a specific arc in the front and back. This creates a static “bar” of light that not only lights the path in front of you, but makes you extremely visible. There are 8 LEDs at 35 lumens, per wheel. That’s a lot, as can be seen in the video below.
The power for the Revolights come from a bracket-mounted Li-Ion battery pack that you attach to each wheel hub. You’re adding 12.3 oz. in heft per wheel, which could be seen as quite a bit by competitive cyclists, but isn’t really that much to the average person. Those batteries will keep the lights on for about 4 hours, which is more than your average bike ride.
The Revolights started out as a Kickstarter project a year ago, which was funded many times over. The company is now selling them at full retail price, which is $250. If you order now, you can still get yours before Christmas.
