Need help with sprocket ratios?

[GlennR]

I reread your question. Since it's a DC motor, why not just add a speed control and adjust the speed by turning the knob down?

Variable speed is the beauty of DC motors, right?


Btw, here's a site for helping choose sprockets for motorcycles. I doubt it's useful for this, but might be handy sometime.
