Wheelchairs are usually built to travel on reasonably flat surfaces. This wheelchair we came across seems to have mutated a few qualities from a conventional tank! Called the Action Trackchair, this one sport treads in place of those traditional wheels and does perfectly well off flat roads. Complete with a camouflage finish, this all-terrain wheelchair sports a top speed of 5mph, enough to get you around and through considerably rough terrain. Sporting gun-racks and mounts just in case you decide to carry a fire-arm on your outdoor wheelchair expedition, the Action Trackchair comes at a base price of $9,000 and makes conventional ATVs seem mind-numbing.
