Image of 5 from iSlide: Segway meets skateboard in radical urban transport concept

These days the term skateboard tends to refer to a whole raft of different transport modes that go way beyond the two-axle, four wheeled conveyances that rose to prominence in the 1970s – everything from in-line caster boards to spokeless mini-motorcycles and sit-down street machines tend to be categorized under the genre. Just when you thought it was safe to go back to the ramp, a new concept has emerged that could see self-balancing technology and electric propulsion incorporated into the skateboard design. The iSlide concept by industrial designer Ofir Tal is a one wheel motorized board that utilizes a hydrogen fuel cell and onboard gyroscope to attain speeds of around 15 kph.
