Yamaha continues to push the limits of innovation thanks to its latest concept, the PES2. Yamaha’s new design is set to make an appearance at Tokyo’s Motor Show displaying 2-wheel drive technology amongst other advances. The PES2 hosts two motors with one inside the wheel hub and the other in the bike’s chassis. A removable battery pack also makes up the PES2′s inner workings which makes it flexible to many occasions. Yamaha also plans on displaying an off-road electric bike dubbed the PED2 that will only be rear-wheel drive.
