I'm with the other guys. It's a crap shoot. I have heard all kinds of horror stories about WM BSOs, but my experience with their singlespeed bikes is a tad different. Yes, I rode it home and immediately disassembled and regreased everything, set the bearings and such, but I had really only ever intended the thing as a winter beater. It functioned well in that respect. I can't even really remember the name of it, it was yellow and came with blue tires.
AFAIK its still running around fairbanks, I get occasional messages from a group out there I rode with. Ill ask them for a picture of it next i hear from them. Mine seem to have poofed
