thats a good choice. I have been looking and looking for months trying to decide what I should do to motorize a bike. My first step when I found out about them was to go to ebay and look for a bike. I like the schwinn chopper so I bought it right away for $104 and I thought 'this is great I can make myself a moped for less than $300' but then I realized I had to purchase a special engine mount $35 And since I liked the idea of a long quiet exhaust I bought one of those too with some chain tensioners and a set of ape hanger bars.
So now I am up to $235 already and I cant decide on an engine!
I would love to get a whizzer kit because the motors are 138cc but then I would have to spend alot more money on turning the bike into a motorcyle. Thats why when I saw your selling yours for $500 I was thinking this is not a good idea, and I really didnt put effort into jumping on it because I thought you would probably change your mind.
