Yamaha's two new electric motorcycle prototypes, the PES1 streetbike and the PED1 dirt bike. The nomenclature is a combination of the initials for Passion, Electric and Street for the street version and Dirt for the off-road model.
Both prototypes are equipped with DC brushless electric motors powered by lithium-ion batteries. The power unit, dubbed the “Yamaha Smart Power Module”, for both models is mounted in a monocoque frame. One innovative feature is a new transmission system that can be switched between manual and automatic modes.
