Ooops! I thought the thread was about the first bike owned. Obviously I had to be taught how to ride at a much earlier age than 12 but I can't remember how old I was or what the bike was (probably about 4 or 5). I do remember my dad walking along with me and at some stage letting go of the saddle. I went to tell him something and got no answer - he had let go and I didn't even notice!I was a late starter. I was 12.
