I have been meaning to help Sam learn how to ride his bike without training wheels for a few months now, but only recently have I really put in some time with him. He is improving but not quite there yet. He will peddle for about two seconds until he thinks he’s going to fall and then he puts his foot down.
When I run with him down the sidewalk and hold his back he does better, but as soon as I let go, down goes the foot. I think he just needs to learn to have the confidence to ride without help and without fear of falling. I think this will happen with practice-practice-practice.
