Skateboarding Down Steps

Those hoses appear to be nothing more than bling. Extension limiters at best...could have used strings.

I checked the other url on that site and the comments there were interesting. Surprisingly so....

One chap explained that it didn't really ride the stairs at all and that the lowered board height just meant that the board could skid down the stair edges and the wheels just hung and pivoted freely.

That the subject ability was only featured for a tiny amount of the entire video seemed to reinforce the idea that this was just a cool design with no special capabilities.

Thanks for sharing.
