Yup, the generator runs on the side of the tire. I want to leave the existing knobby tire on so the bike remains usable in short order.
So this afternoon I
picked up a junk 12v battery.
And... it works! I
can charge it with the bike.
Also, I've linked to the images in the thread instead of using attachments, so you don't need to be an EcoRenovator member to see them.
