For last five yrs I have tried to build a fat wheel pit bike that is a lifan motor pit bike with a three wheeler rim/tyre fitted to a moded alloy swing arm. This project has taken five yrs due to moves and me giving up a few times. I know have gotten closer to getting a serious contender for a functioning bike with all factor considered, and there is a few! I will post a few pics as I complete. I has been a complete waste of money and a total frustration, but it will be one of a kind. Will keep anyone who is interested posted. Matt
