Working to help a friend who was paralyzed in a skiing accident, engineer Kevin Halsall spent four years modifying a Segway to become a wheelchair. The user simply leans in the direction they want to go — no need for even a joy-stick to make it move.
The two powered wheels can be changed quickly for all-terrain tires, allowing a user to race down a sandy beach at 12 mph — the average adult running speed or twice as fast as most people jog.
