Hi, I'm new to forum,thank you. I wonder if you guys can give me some help or advice on a problem im having with a mxus 5k turbo hub motor. I can't seem to get a single speed freewheel to fit on the hub? I have tried two freewheels including a halo clickster and they both screw onto hub maybe 4 or 5 whole turns and then they bind up on thread? I don't want to force them on and damage hub so I'm thinking there the wrong thread or pitch? Everything I seem to find on net is a 1.375x24tpi which seems to be the standard size now? But I have no idea what thread size is on hub? Any help or advice would be greatly appreciated. Many thanks.
