My freewheel started freewheeling in both directions and I walked the bike the rest of the way. I'll see if it will hook up on the way home.
I had some water trapped in my rear hub earlier this year and it froze up my hub, just like what you are experiencing. I pulled it apart, flushed it out with some alcohol and repacked the bearings. So far it's worked well down to -20F.
