Just want to know I bought a new 12gauge rear freewheel wheel for my mountain bike. Do you need a hub adapter to mount on the rear sprocket for motorized bike . Of course I can't mount it on the threaded side where my new threaded freewheel is going because I need to peddle the bike it's a friction clutch. It don't seem to mount on correctly on non threaded side. This wheel is also quick realease it's strong and bad a** any help is much appreciated because I think I have it on all wrong.
