It's difficult to say, because of my blurred memories, but I think we bought a bike after we had moved out of my grandparents' apartment into our own place (that was when I was eight). I think I was about 10 or 11 then, but it could've been earlier too. I've been able o ride since, but I'm not that good at it. That is, I've never had any of the more severe corrination trouble that some oher people have, but I'm not entirely comfortable when riding. I have to concentrate on keeping my balance all the time, and I can't ride too fast or downhill (definitely not both at the same time), and any more or less pronounced bump in the road may make me fall. Whenever I see bumps or pits approaching, or the road starting to slope downwrds, I begin to panic, hop off the bike and push it along while walking beside it, until I've passed the difficult stretch.
