The idea behind the Vertrax concept skateboard is the ability to cruise over a variety of non-paved surfaces with thick treads. Does it look cool? Sure! Would it work? We'll never know! But it is a neat piece of design.
The all-terrain renders are from the portfolio of designer Bryson Lovett, who imagines the Vertrax being electrically powered and still able to carve from side to side at "the beach, ski slopes, or even the desert." [Bryson Lovett via OhGizmo!]
