Sure, the Segway looked cool initially, but it’s expensive and bulky. Here’s a much smaller, more portable human transport called the Treadway. Essentially, it’s a motor, battery, and wheel which you attach to the outside of your shoes.
Treadways are lightweight and feature directional control is via a wireless controller. The battery pack is worn on a belt around the waist and it is rechargeable using any electrical outlet. Full power on the prototype gives 15 mph. Watch the video to see the design changes the Treadway Mobility shoes went through.
