My LBS is called "Build a Bike" and carries mostly cruisers and some bmx. They have some really cool custom stuff there. Randy, the manager will help you out with your bike but he wont work on anything to do with the engine.
That wasn't really a problem for me as I only needed some minor assistance, but the whole time he was saying things like, "I hear a lotta bad things about these" and "Why would you want to put an engine on a bicycle?"
My question is, "Why wouldn't you want to put an engine on a bicycle?"
