Hi all, I'm trying to get into this whole motorized bicycle thing, but I know very little about it right now. I'm pretty experienced with mechanics and modifying cars, but bicycles would be new to me. I'm thinking about getting this bike: (edit) I can't post a link Men's 26" Huffy Cranbrook (Wal-Mart Website) Where could I get an engine that will fit this bike? Keep in mind that I want to start off simple, I'd like to have to do as little modification as possible to get it mounted and working. Thanks.
