I have been trying to get my son a bike and many years I have gotten him one and his mental stability is not up to the task it overloads him when he's tried to learn how to ride a normal bicycle and I've even gotten him training wheels and all kinds of things to try to figure out how to do it and he needs the straps over his feet or he needs something for his back and this will help strengthen his knees from when he's broken his kneecap and his ankles and feet it'll help strengthen him!
