I have a 17 year old son with Down's Syndrome. He is only slightly taller than my wife but has at least 25 lbs on her. His balance is terrible and his attention span is not that great either. I keep saying I want to try to get him on our bike, but I'll have to swap out for platforms before I think of attempting it. I'm sure he'll be a handful but if we could manage it would be pretty cool. It would have been great to do a ride like Best Buddies with him.
