A retired couple in Michigan believes that every child should have the exalted feeling of riding alone with the wind in their face. So they build custom-made tricycles in their basement for hundreds of small children with disabilities.

It costs about $200 to outfit a standard three-wheeled bike to help stabilize kids with cerebral palsy and other physical challenges.

So far, 900 children now have the joy of riding free, thanks to Gordon & Connie Hankins.

Other physical benefits result, too, when kids are pushing their muscles.
