Some of us remember a time when you could get roller skates that fit shoes. Moonwalkers have the same idea, except that the goal with their project is for the wheels to be powered, to drive you forward at a maximum speed of 11 km/h.
Speed Increase Depends on Base Walking Speed
They claim that this would increase walking speed by 250 percent, but I already walk at 5 to 7km/h, so it would double walking speed. Theoretically, this is a fantastic idea because it allows people who walk more slowly to get around more quickly, whilst walking. The drawback is that, as with all these developments, they are designed for urban, rather than rural use. They are designed to speed up getting around for people who already have access to buses, trains, foot scooters and more.
