    I am getting ready to motorize a GX7. It has 29 inch, 48 spoke wheels. Is there a sprocket adapter that will fit this? My concern is not the hub diameter, but more the 48 spokes.

    What is the hub diameter?

    The large Manic Mechanic sprocket adapter fits a coaster brake 48 spoke wheel.

    With all the spokes, it's hard to wrap a tape measure around it, but I got around 3 inches. It's a 7 speed derailleur on the back if that helps.

    this is what you need to measure diameter of the hub.

    knowing the exact size of the hub is critical for making sure the adapter will fit the wheel properly.

    Duh, sorry, I gave you circumference. It comes out to just about 1 inch diameter. That's converting the circumference to diameter, since I don't have one of those tools.

    I'm a little late to the thread, but the SBP jackshaft shift kit works great with that bike, no need to hassle with rag joint in the spokes!
