The advances in technology for those in a wheelchair have come on a lot in recent years, and more and more people confined to a wheelchair can do things able bodied people can. So it stands to reason that people in wheelchairs can also get some awesome extreme sports fun in the form of the Der Ziesel Electric Tank Wheelchair ($30,000).
Literally a chair on two giant caterpillars, this is a mini tank that will destroy just about any terrain you can throw at it. The Tank Wheelchair is mega light, so the 21 horsepower and 30 lb-ft of torque will propel the machine along at 22mph, while the battery will last for 4 to 5 hours. Hell, you do not even have to be in a wheelchair to enjoy the 21 horsepower and 30 lb-ft of torque.
