I am new to the site and am sure it will be fun. I just sold a 12 speed Miyata bike. I am trying to find an older schwinn bicycle that I can put a 48cc motor kit on. Can anyone give me some ideas as to where I might be able to find one other than the local paper and online classifieds? Walmart has some basics but the frames look weird and not the round tubular type frame that I think will be needed to mount an engine. I could be wrong. Any advice would be appreciated.
