These bike engines can be fitted by any competent DIY person in a couple of hours. Then, just imagine inviting some friends for a bike ride and watching them as they huff and puff climbing that never ending hill. You, with your new bike engine, will of course just effortlessly cruise all the way to the top.
But be warned, your friends of course will now want a Star Fire Bike Engine for their bike and guess who will have to help them bolt it on.
