What size sproket for 20" wheel?

    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:
