Our company specializes in therapy for special needs children. Part of therapy is preventing physical and mental defects before they happen. If more children were active and receiving sensory and motor input as well as physical exercise there would be less need for special needs therapy. This unit gives your child all the exercise he or she would need in a day and will be one of the most fun toys they have ever played with. Just remember back when we were children. This is what we did. Go outside and ride a bike or ride a big wheel. Do you remember hearing of autism or a.d.d. or a.d.h.d.? Probably not. You know why? Because they did not exist!!!! We offer this product at a very reasonable price because we believe that learning should be fun.
