When I was growing up on Anglesey in the 70s/80s, there was an old guy who used to trundle around on his bike, a serene expression on his face and often a pipe in his mouth. My dad later found out he was an Olympian - I can't remember his name but I think his event was the tandem track (sprint?), he may have won a bronze, I'm not sure. He must have been well in his sixties by the early 80s, so it could have been 1948 I suppose. Any ideas where I could and try and find out?
