This video shows a chopper bicycle with a solar panel installed in the front. Ihe chopper is using an electric hub motor, super capaciters, and the solar panel for the power drive system. It appears that the bike is running only of electricity collect from the sun.
This video is labeled as a "solar bicycle". It was designed by engineering students at a University. It appears to have a few solar panels embedded in the top of it's skin.
Come ride along on my helmet aboard a solarized P-38 recumbent bike.
