    Here is handy tool to determine your speed roughly

    10 tooth front and 36t rear @ 6000rpm should get you 41mph or 65km/h ---> 3.6 ratio

    10 tooth front and 44t rear @ 6000rpm should get you 33.5mph or 53Km/h----> 4.4 ratio

    10 tooth front and 48t rear @ 6000rpm should get you 30.7mph or 49km/h----> 4.8 ratio

    all based in 26in wheel diam

    By some fabricating a 12t front engine sprocket we can achieve roughly a 10 to 14km speed increase to motor.

    now Iam not sure what the torque power would be like

    can we have more input to this topic

    I have noticed over at the cycle shop they have replacement front sprockets 15T, etc. Not sure how the sprocket splines on the bicycle motor or if they would be interchangable.
