Convert fixed side of flip flop hub to freewheel I have a flip flop hub and I'd like to convert the fixed side to be free wheel. Is this possible? If so how much might it cost?

My motivation for this is that:


I never ride fixie
I'm running a 46/16 and would like to have a lower gear ratio (46/17 or 
46/18). It would be really nice if I could keep the 46/16 and just flip the hub to have a different gear ratio.
You can just use the freewheel on the large thread on the fixed side. It's the same size, and just as durable as the freewheel side, for normal people.

So just unscrew the lockring and cog, and put on a standard freewheel of your choice. Did it as a bike messenger, and it still holds to this day.

Happy riding!
