Been kinda lurking for a while and think I want to make the jump, however am confused with which engines. I see references to china engines in the forums as well as a couple manufactures I don't know where to get. Think I probably am looking for a kit, but even that is confusing. 48 cc or 80cc (probably 80). What is the difference in the manufacturers. First I thought about an 80cc from SpookyTooth for $250, now i see BikeBerry for $150 and BiketoMoped for $299. What is the difference to cause the price fluctuations? I did awhat I thought was a pretty good search, but if there is a faq or other thread, or even kit supplier I need to look at, please point me there.
