I think a 23" (58.4cm) was the biggest the Trek 520 was sold in, at least by going off the 90's catalogs I have seen. There may have been a larger size in the earlier years.

I'm 6'2" as well and fit a 23" 520 nicely. I have shorter legs, compared to my torso, so any larger and I wouldn't clear the top tube.


You didn't mention whether you want drop or flat bars so I'll echo either a vintage mountain bike or touring bike. Just note that rim brakes are not the best in wet conditions like Seattle, discs are better at that.
