i have those same mags ...i junked the rest of the bike ...i thought it was weird also .... wonder if a guy could put a single speed freewheel on there ? prolly huh ...
Yes I would say you could put a regular single freewheel on if you changed out the axle. I have had a few sets of these mags on single speed bikes and almost every one I had, had a craked mag. So be sure to look yours over before riding. Matt
