Hi everyone, I have been riding a moped since 16 and have come to love riding, so I wanted to build my own trike now that I am turning 17. I want to build it completely from scratch but I have no idea where to start. My dad is a mechanic so I can use his tools and such, and he advised me to start with a VW rear drive engine but I don't know which one to use. On top of that, I don't know where to look for trike parts for sale to compare what I want, so I came here seeking advice. Thanks.
