Background info before my question:
I have a Staton-inc axle mounted gas kit on a 26" wheel bicycle. My current top speed is 28mph, using a 13 tooth small sprocket and a 60 tooth large sprocket. I can adjust my top speed by changing the size (the number of teeth) of one or both sprockets. However, I'm not satisfied with the variety of large sprockets for sale on Staton-inc.com, because I can't dial in my top speed more precisely. Therefore, I want to purchase a custom-made large sprocket from www.electricscooterparts.com, so as to better dial in my top speed closer to 30mph.
Question: what is the mathematical formula (or ratio) for calculating the top speed of my Staton-inc axle kit, given that the only two variables in the equation (or ratio) are the number of teeth on the large and small sprockets?
I can order a custom-made large sprocket from www.electricscooterparts.com with the exact number of teeth that I specify. For example, the large sprocket can have 53 teeth or 47 teeth -- whatever number I specify.
I want my top speed to be as close as possible to 30mph, yet without going over 30mph. My ideal top speed would be precisely 30.0mph, but somewhere between 29.5mph - 30.0mph would be acceptable.
I hope to use an 11 tooth small sprocket, which I've already purchased from www.staton-inc.com, along with a custom-made large sprocket.
Thanks.
