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.
