Most stingrays have 20" wheels, a little small for a taller person. Schwinn made a 24" wheel bike called a Manta Ray, in the schwinn book it's described as the bike favored by fat kids and bullys. I have a Sears verson of the Manta Ray I bought on Ebay about ten years ago, I didn't pay much for it. I recomend finding a frame and wheelset you like and buying the seat and handlebars and build it yourself. I have one with a springer fork, old style shifter we always called "nutcracker shifters" and drum brakes that I built myself. That bike actually started it's life as a mountian bike. I'm leaving for vacation for a week, when I come back I'll post a couple pictures that might give you some ideas.
