Yeah, but you need a lot of surface to catch the rays. That's got to be the most sensible placement I've seen for collection surface on a bike. About the only problem I see is a high incident angle when the sun is at apex, so charging would be limited to early, and late, while riding perpendicular. Or, you could lay it down while you work, and charge up for the commute home! If you use in hub motor/controllers, then all you have to worry about is the power supply. Some companies make batteries for the frame triangle.

It should work fine in most cities, but out here in Montana you'd be pedaling while flying with that kind of surface area exposure.

Cool in theory, but those would absolutely suck to have on a bike in even a remotely noteworthy sidewind--it'd push you around like a kite on a string.
