    I will save you and others the trouble of finding that thread and send you to the source

    livefastmotors makes one too but it isn't as good and is more expensive
    jims is custom bored to fit your hub and worth the wait

    I think 'Creative Engineering' in this Forum came up with a bolt-on rear wheel sprocket adaptor, if memory serves me correctly.

    if you get 54 teeth you will be getting more for your money

    (more teeth = less $/tooth)

    40 is a nice compromise between low end (torque) and top end (speed) :cool2:

    44 teeth is standard
    34 is about as low as i would recommend for a light rider on flat ground
    without a lot of stop and go with a strong 66 ccc engine

    so pick a number in between

    Thats one killer idea, never seen one before! So the gizmo transfers torque from the gear to the hub w/o stressing spokes! Awesome!

    the sprocket is driving directly to the hub with NO contact to the spokes

    Just a idea. You could get 2 sprockets to go with the hub. A 34 and 40. Would fit most needs.
    Would like to see a set up like the old small bikes had. Sprocket in a sprocket.
    You will be happy with the sprocket and adapter setup, smooths out the the ride so much.
