Back at the 2007 EICMA show in Milan, Taiwanese scooter company Motive Power Industry Co. Ltd. (PGO) was showing off a new electric scooter. The design of the machine apes a model that they already sell, but the innards are actually pretty intriguing. The scooter uses both lithium ion and lead acid batteries. The lead acids provide the necessary power to move the machine while the lithium ions act as additional storage. When a large lithium ion battery pack is assembled, small cells are placed in both parallel and serial configurations in order to hold enough juice for extended running while also being powerful enough to provide quick bursts of acceleration. In this case, the lead acids could provide the necessary output while the lithium ions could just keep the system "topped-off."
Take a close look at the picture above. Note that the front wheel is powered by an electric motor. We can't confirm this for sure, but this appears to be a two-wheel drive electric scooter, which would be really awesome! There is a small chance that a version of this scooter could make it to U.S. shores, as Genuine Scooters in Chicago currently imports certain models from PGO, including the one that this scooter is based on. In the states, it's called the Buddy.
