I bought this hub for a custom motorized bicycle project. I laced this hub to a 24" bicycle rim with 11g spokes. It went together fine. I haven't run the hub yet, but the only issue I ran into so far was that the spacers that came with the hub could have been a little longer. The freewheel was rubbing on the frame. This problem was easily solved by adding a washer to both sides of the hub right beside the spacers. So just be aware if you buy this hub, you may need washers for extra spacers.
