Hand crank flashlight on bicycle?
 

I was checking out thinkgeek and saw this. It says you crank it for 1 minute to provide for 45 minutes of light output. I was wondering if anyone has mounted one of these on their bicycles to where they can ride at night without an expensive bicycle dynamo setup and without having to replace those pesky little watch batteries.

"Up to 45 minutes" means 45 minutes on the "low beam" mode. If you ran all three LED's I'm guessing you'd be closer to fifteen minutes. I doubt it throws much light, either. Why not just get a CatEye setup and a fistful of rechargeable double-A's?

I've got something like that. It isnt bright enough to be a full-time bike light and has no mounting mechanism. If you were really stuck it would work in an emergency, taped to the bars with pvc or duck-tape.
I have one bike with a full dynamo setup and another with the dynamo lamp powered by a separate rechargeable battery in a waterbottle. .
