The Lightest Electric Scooter on the market is the Zoom Air 2 - at 10.7 KG, it is easy to bring around on the train, bus, and still gives a good speed up to 25 KM/H.
Looking for something even more compact, and unique? Then check out the Wheelies AirWheel X3. It is only 10 KG, and is the smallest vehicle you can get that will bring you anywhere you want. The Wheelies takes some practice, but once you master it - you will be cruising everywhere without a sweat!
Our newest kid on the block is the Deux Cruiser | Hoverboard. Made popular by the numerous celebrities using this technology in the U.S, it is easy to use; just step on the pads and lean forward to move. It can even be used by kids, or if you have absolutely horrible balance - you'll still manage on it!
