The sexiest electric vehicle in the world right now is arguably the Tesla Model S luxury sedan, but now there seems to be a race on to design the smallest electric vehicle in the world.

First came the Commute-Case from Green Energy Motors, and now we have the less expensive (and rather less glamorous) Trikelet.

The Trikelet scooter has three wheels--two small, closely-spaced ones at the rear and a larger one at the front that steers.

It folds up into itself, forming a sort of box on wheels with a long handle that resembles an odd-looking roll-aboard suitcase.

The 27-pound (12-kg) Trikelet not only folds up but, as the makers say, "fits in the luggage compartment of the train".

The video shows it being loaded into the cargo bay of a German-market Volkswagen Up minicar, and shows it being used as a "last-mile" solution for trips via car or mass transit.

The top speed of 12 mph (20 km/h) is about three times the pace of a brisk walk, and its makers say it could be brought to market for 1,000 to 1,500 euros ($1,350 to $2,025).

Its makers are still developing the Trikelet--they need about another year, they say--and are seeking both distribution partners and mass-production funding.

But with electric two-wheelers expected to outnumber plug-in electric automobiles globally, we'll likely be seeing a lot more of these kinds of little electric mobility appliances.

Frankly, we're just waiting for a handful of electric skateboards to replace the ones with noisy little airplane engines buzzing away on their tail.
