Can Bicycle Shops Last 70 Years

Bill's Cycle is on Roosevelt Avenue in Woodside. I've never been able to find out anything about the place, but the sign says Est. 1939. Is that possible? I know the bike biz is a tough one, with slim profits. If Bill's is really 71-years-old, I'd say that makes it the oldest bike shop in NYC. Whaddaya say, Queens people—anyone know anything about Bill's?
