Hello, I'm from S.E. Michigan and I'm thinking of building a motorized bicycle with a 70cc lifan engine. I'd appreciate any help in picking out a frame and components and any pitfalls heading my way. At this point in time, I'm planning on using a stretch beach bike frame, a springer fork, having a suicide shift on the left. I don't know whether it would be better to have a left side drive in the back or go through a shaft and use the standard right drive?
