I learned how to convert a DC motor into a generator and attached it to the back wheel. I ran a cord to a organ that i modified to use DC power and now you have an Organ Bike. The faster you ride, the louder the organ is. You steer with the keys and play at the same time.
I just walked out of my apartment one day and saw both the Bike and the organ in the trash. I kept them in my place for a while, who would ever guess that they would go together.
