Just an update on my son. He is 11 now and in his way hinted he was interested in riding since he has outgrown the hitchhiker. So I took the pedals off my wife's comfort bike and lowered the saddle. Told him to coast. He did this off and on all summer, but rather slowly. Monday we went to a parking lot and he said "I wish I had pedals." So last night I put on the pedals and in half an hour he was pedaling all around the parking lot. Balance and braking still need work, but he did it! I am so proud of him. I guess I just needed to wait until he was ready and motivated.
