For people with disabilities the durability and usefulness of wheelchairs is very important, but even though inventors are constantly improving the design, there are still some issues that are yet to be solved. One of those is definitely moving through challenging terrain. Thanks to some guy and his new invention, wheelchair users now can push over surfaces that would typically be impossible.
FreeWheelTM Wheelchair Attachment is a single wheel that easily clamps onto the footrest of almost any wheelchair and allows an individual greater stability in negotiating curbs, grass, snow, rough roads, uneven ground and more. This life changing innovation was first shown to the world at the 2011 Abilities Expo. Very creative definitely, hope it will help many people lead a much easier life.
