What size sproket for 20" wheel?

[boyntonstu]

I believe that a sprocket designed for a 26" wheel will reduce the speed of a 20" BMX sized wheel.

What sprocket size would equalize the 20" wheel performance?

(Or possibly change the engine sprocket?)

If my calculations are correct, and they sometimes are, a 36 tooth sprocket on a 26 inch wheel should provide the same speed as a 28 tooth sprocket on a 20 inch wheel.

How many teeth on a China kit sprocket for a 26" wheel?

Are 28 teeth sprockets available?

I've never seen smaller than a 32 tooth. the stock sprocket with a china kit is a 44 tooth sprocket.

44/32 = 1.375

26/20 = 1.3 pretty close.

I just found this on Craigslist:
