So As I surfing the ebay I found something called, NAPSR skateboard. https://www.ebay.com/itm/The-X-Calibur-Full-Race-Electric-Skateboard/273112393351?hash=item3f96c46687:g:2wAAAOSw8A1ajL4W
So it is Esk8 with scooter wheel at back, in his describtion : The X-Calibur Full Race Electric Skateboard Retails Only As A Custom Made Racing Skateboard That Is Known To Hit Speeds Exceeding 50mph. It is the only Powered Skateboard that is approved by the NAPSR, National Association Of Powered Skateboard Racing League. The average cost of these boards is well over two thousand five hundred dollars (2,500.00) The X-Calibur Full Race Electric Skateboard Is The Only approved Skateboard By NAPSR Racing Please Google Or You Tube NAPSR Racing. I am The Patent Holder On This Skateboard USPTO 8061725. I am slashing the price on the two working Skateboards to 700.00 a piece.
Which I though it was a joke and encounter this on youtube.
Is this still going on or is it Relic of the past?
