Taking full advantage of the greater chassis design freedom afforded by an in-wheel motor, this is Yamaha's proposal of a completely new type of two-wheel-drive (2WD) EV (electric vehicle) with "Stretch" functions in the vertical and horizontal directions for the aluminum frame body that brings a very Yamaha joy of riding. In addition to the great drivability of the 2WD, it is possible to adjust not only the riding position but also the silhouette of the chassis to fit the rider's body size, riding environment, road surface conditions and personal preference, as well as output characteristics. This is Yamaha's proposal of a bike of the future that offers the kind of personal fit only possible with an electric vehicle.
