One of the common headaches with bike lights is battery life. Some lights run off of AAs or whatever, but then you need to get new ones when they expire. Others are rechargeable, but you need to do the recharging, naturally. Imagine if there was a bike light that didn't require batteries!
There is! And it's not one of those hefty dynamo driven lights that make it harder to pedal (though ever-so-slightly), it's the Reelight. It uses a pair of magnets that are screwed onto the spokes of your bike to power the tiny dynamo within the light, therefore effortlessly providing power to the lights as you ride.
Pretty neat - and anything that makes safety on your bike easier is a good thing.
Edit: Fellow blogger and frequent commenter on this blog Fritz posted a review of the Reelight at Commute By Bike. Check it out!
People, not speed.
