While the three-wheeled hybrid scooter from Piaggo we featured earlier this month boasts some impressive performance statistics, it's easy to see that it might not be for everyone. The dual front wheel looks a little funky, the company is still reviled in some circles for its association with the Vespa, and some people will have a hard time getting over the fact that the MP3 still uses gas.

For those folks, there's the Brammo Enertia. Fully-electic, the bike can exceed 50 mph, and range well over 45 miles on a single, three hour charge. At a scant 280 pounds, the bike should also be fairly easy to handle after a dismount—not something a whole of other two-wheelers can boast. And on the style front, it presents all the elegance of a vintage Triumph crossed with the high-tech edge of a Tron light cycle.

The Enertia is also unique in its recent decision to use Valence lithium-phosphate batteries. Most lithium ion batteries found today in electronic devices are lithium cobalt oxides. Though lithium cobalt oxides can pack a lot of energy into a smaller space, they present a variety of problems, including the tendency to explode, a higher production cost, and more toxic byproducts when disposed of. By chosing lithium phosphate batteries, Brammo has dramatically reduced the lifecycle impact of its new vehicle.
