Yeah I saw that. Good news for anyone who wants to try them out.

runrunn and irclean, just an FYI, I swang by my bike co-op on Saturday morning as part of a morning ride I was finally able to take. We took apart the whole bottom bracket assembly, cleaned it all out and repacked the bearings. There were two or three metal filings of mysterious origin amidst the grease and bearings. Obviously, we took them out. I say mysterious, b/c in the mechanic's estimation, everything looked good otherwise (i.e., nothing had been obviously damaged that would have caused the metal to be in there). Anyway, got it all put back together and the noise is gone. I hope it's as simple as that.

If the click comes back, I'll look into replacing the BB. In the meantime, $10 worth of work stand time at the co-op seems to have made the noise go away. Plus it was a fun, educational experience to pull the cranks, service the bottom bracket, and reassemble. Fingers crossed, fellow Schwinn hybrid owners.
