Batten disease is a rare and fatal disease of the nervous system. David goes to physical therapy and our doctor said that it may help him retain motor functioning as long as possible. And bike would help us a lot both for therapy and as a fan, of course. David is very fond of riding and being outdoors, he would be happy to have such a bike.
