I don't recall the author mentioning it but they already have what he describes. It's called a kick bike. My two oldest grandchildren learned to pedal after fighting to not have training wheels taken off at like 5 and 7yos. The next two started on a kick bike at 3 and were flying around the neighborhood like it was nothing. In time they got right on a pedal bike and off they went. Highly recommended. I hope the original inventor got rich off the idea because it is a really great idea.
