An eight-wheel mechanism allows the unusual Stair-Rover skateboard to descend flights of steps the way conventional skateboards never could. Designed by Po-Chih Lai, the wheel system mounts to a longboard and flexes to follow the contours of stairs and ride up curbs.
In addition to the original design, which fits wood boards, Lai offers an upgraded Pro version with a fiberglass deck and black components. The chassis goes to work on rough surfaces like cobblestones or uneven paving to reduce impact and prevent falls.
“Reach the top of a flight of stairs and simply keep going – let gravity and the patent-pending V-frame design do the rest. The wheels bounce up and down independently and conform to the shape of each step. It’s a balancing act that gives the board its crab-like scuttle and gives you a butter-smooth ride to the bottom.”
A new video of the board in action shows it navigating London landmarks like the Royal Albert Hall, Emirates Stadium and the Millennium Bridge. Currently up on Kickstarter, the project is seeking £50,000 in funding to bring the board into production. Backers donating at a certain level are pre-ordering a board before it’s available to the general public.
