My bike is messed up. One pedal fell off, th other is starting to come off, nd i need to ride it A LOT! (school, park, down th block...) so i looked for ways to motorize it WITHOUT buying a motor kit. And i used to have to weed whacker things, but ones..gone, nd i need the other. So i need to figure out how to motorize a bike without using th weed thing, or spendin money (no way for me to make it, hard to save, nd wallet lost)
