as a 6 or 7 year old, i was put on a little bike with training wheels. A grownup would push it and let go. I was absolutely terrified and after that experience, I had no interest at all in cycling. When i was 9 my father bought me a 24" wheel bike. He got on it and rode in a circle. he gave it to me.. I did the same. I was riding! just like that!
