Hatfield, a Bay Area entrepreneur with 20 years experience developing electric vehicles, first caught our attention in 2007 with his electric-powered Yamaha YZF-R1. That development mule led directly to the Moto-1, the prototype of a street-legal electric sportbike Hatfield expects to put into limited production by the end of 2010. The prototype is a bit of a mongrel, but with an impressive pedigree. A&A; Racing's Ray Abrams (Kenny Roberts' go-to frame guy) built the steel trellis. The rear wheel is from one of Roberts' Proton MotoGP bikes, while the Marzocchi fork once resided on a Fast by Ferracci Superbike. Drive is courtesy of a liquid-cooled motor from the supposedly disappeared GM EV-1 electric car. "If I told you where I got that, I'd have to kill you," Hatfield says. The custom battery pack is built from the same A123 Systems lithium-nanophosphate cells that Tesla uses in its electric supercar.
