I taught Jules to ride a bike on Long Island. The trick is to use the advantage of a spinning wheel (gyroscope) that tends to stay upright when spinning fast. I just pushed from behind, gave her the notion I was holding on, and then let her go off on her own. It wasn’t hard. She got the hang of it right away. I learned from my mistake with brother John. I tried to get him riding on our lawn in Elkins. He couldn’t peddle well enough in grass to stay upright. Hey! You learn. David was younger but quickly followed his sister’s example.
