Thanks for the article link. I’ve been curious about these since I first saw the kickstarter promo video.
It’s a little bit too novelty for me since it’s not going to light up enough dark pavement to see a good distance in front of you (some streets in my area have very little lighting). The hub mounted battery is a bit clumsy, but their site does mention a future hub dynamo powered possibility.
That said, imagine what a group of riders with these on doing Hains Pt at night would look like!
