Thanks, Cuda -
I'd like to keep riding it - I can't commute right now due to distance and work schedules, but weekends (during the winter) and evenings (once we get back to DST) are good. I haven't ridden in a while, but I can't make myself go to the gym often enough, and I will ride regularly once I get back in the saddle. My wife is also getting back on her bike - so I won't get grief for spending time on the bike.
I am also looking at bents - haven't test-ridden any yet. I really think a bent or even a trike would be good for the wife. She has some breathing and dizzyness issues that worry me a bit with her on a DF bike. Anyway, I will see what I can find locally for a replacement wheel, and one gentleman on here has an old Trek rear wheel we are discussing.
So, I appreciate the advice, and that of anyone else who wishes to chime in.
