Another option would be a bottle gen like the old bike light ones but DIY and wound for 12 or 6V and at around 15 or 16 MPH. (What I have found to be the avg, motorized bicycle speed)
Another option is a rechargeable system. But I think the best would be a solar panel with the option to plug in to recharge a battery system.
But you are gonna get some great thoughts and suggestions. Just MHO there.
Thanks for the response, its too bad there is no electrical output, and it doesn't sound like making one is easy by any means.
