How many teeth should my sprocket have?
I've got a chopper bike, solid build, looks pretty nice, but the back wheel is only 20 inches in diameter. I've got a 80cc engine coming in the mail tomorrow, and I'd like to know if anyone knows how many teeth I should look for on eBay (with a wheel this small, a 44t is going to be much too large) for a replacement.
The bike is about 25 pounds, and I'm 130. There are some medium sized hills here, but nothing too huge.
If anyone has experience with small tires, and knows what might work best, that would be great.
