Ok everyone I am making another custom minibike. Welding a frame, fabricating parts, you know. Anyways I am planning on putting on lights and a horn, and want to get it registered. However, I can't just keep changing out batterys and I want to be able to drive without fear of dying. So my question is, is it possible to generate electricity sonehow? I heard sone motors can have diods/alternator parts and voltage regulators wired to the coil, and they can generate 12v DC.
