the wrath of the SUMO

The company says the futuristic motorbike enjoys high energy efficiency thanks to a state-of-the-art magnetic motor which is a hybrid between a electromagnet and a permanent magnet. The new motor, called SUMO, short for "super motor," is housed inside the bike's rear wheel. The manufacture says the new motor is seven-times more cost efficient than gas-powered scooters. http://video.google.com/videoplay?docid=-7356522113050137185
