[93KgBike]

I think they are a great idea, and my wife even gave me one a few years ago*; I just pulled it out of the box to see if it's still there. It's a single unit called Contour that does a med/wide angle in 1080iHD for about an hour, or several times that in SD. It's probably a brick by today's weight std I'd bet.

Could be it was the charging ritual maybe, or having to deal with the computer, perhaps - I'm not sure, but I just never got going with it. I think it relates somehow to my preference for dyno hubs over battery lights.

*Actually, it was two weeks after my first son was born when a young physician, showing off for his new wife almost killed me with his very nice new BMW (they were both sweet people). I should give it another try this year.
