Yamaha Deinonychus concept
The Deinonychus concept shows off the radical research by Yamaha engineers into an electric bike that can adjust itself to different riding situations. In this picture, it's in a commuter position. It can dip into a cruiser position, which gives it a chopperlike look, or stand up in a BMX position. It also has a parking position where the foot pegs drop down to serve as a stand. It uses two hub-mounted motors along with a battery pack under the seat.
