My son learned how to bike recently. They Tour de France was taking place, which motivated him to try once again. We live at the end of a cul de sac and I ran around with him, holding his bike seat, as he peddled and worked to find his balance. Without planning it, he took off down the street, unassisted with me running behind him. That afternoon, we probably covered close to three miles – he peddled and navigated the street to the main road and down to the park while I ran along side or way behind yelling for him to slow down. The sidewalk on the main road is wide and a great space to learn how to ride a bike.
