Today we will move back a little bit to the 2015 Tokyo Motor Show, where Yamaha unveiled its concept electric motorcycles - PES2 for the street, PED2 for off-road and bicycle YPJ-MTB Concept.

The Japanese company isn't yet publically offering any plug-in motorcycles, but the tipping point is approaching...we hope.

Here we have a set of photos and videos from the show:

"The only thing you hear is the sound of the wind rushing by; this is the future of road-going sport bikes. The PES2 is the product of a pursuit to create a sport EV that can provide performance never experienced before. The second motor is built into the hub of the front wheel, making this a 2WD motorcycle. From starts to cornering, the PES2 heightens the feeling of road contact and ensures efficient transmission of drive force to the road in a way that never feels unnatural to the rider. Also, the “smart helmet” serves as the base for a next-generation rider-support system."

"This electric mountain trail model was developed with a theme of coexisting with nature. The torque from the electric motor is precisely controlled by means of our electronic control technology to deliver performance that makes the PED2 easy to use even for beginners as well as delivering plenty of drivability at very low speeds. The PED2 uses the same main electric power unit as the road-going PES2. The only noise emitted by the PED2 is the light hum of the motor, allowing you to quietly enter the woods and ride on trails without disrupting the serenity of the sound of the birds and the wind rustling the branches overhead. Whether it is for bird watching or just exploring a new trail, this is mobility that opens up new way to enjoy the great outdoors. "

"This electrically power-assisted mountain bike mounts an electric motor on a high-performance bicycle and is designed for adults who want to enjoy the freedom of being able to ride on virtually any terrain. It lets you feel the presence of the power unit where it is most appreciated, like in starts, acceleration and hill-climbing, but with a design that minimizes the visual presence of that same power unit. For added assurance in riding longer distances on any type of terrain,the model is fitted with a large-capacity 400 Wh battery and a multi-function instrument panel. This YPJ project is about offering new value and new scenes for bicycle riding, and this mountain bike concept model redefines the positioning and functions of electrically power-assisted bicycles from a vehicle that makes riding easier to one that opens up a new realm of sporty recreational riding."
