Grinding down flights of stairs isn’t always easy when you are on a skateboard, so Po-Chih Lai decided that skateboards could be improved so that they would have no problem going down steps.
The Stair Rover skateboard uses extra pivoting trucks with two wheels on each side to follow the contour of stairs, allowing the board to ride down smoothly. While the video shows a skateboarder using the Stair Rover successfully, I wonder if it has enough ground clearance for all kinds of stairs. Nevertheless, it looks like it works well on a variety of bumpy surfaces.
For now, the Stair Rover is just a working prototype. There’s no word if it will ever be mass produced, but I can think of people who wouldn’t mind having the extra wheels that they can thrash down stairs.
