I never had a new bike till I was about 35, somewhere around 1975 or so. I never paid much attention to how they were made or what size they were. I just made do with what ever I could get at the time when I was a kid. My first new bike was a Panasonic road bike and I didn't have a clue why I got that one. I guess the sales person just felt thats what I needed. Lots of bikes since then, but I was never one much for looking at the design complexities.
