Zweistil is a bicycle prototype developed by Stefan Wallmann, a renowned German industrial designer, with the shape changing ability. This innovative bicycle will provide the rider with two riding options. First one is a compact shape for traveling around the city when you have to be more alert and aware of the busy traffic around you. The second option is for long distance rides when the rider can lay back with leisure and enjoy the views. The transformation process is simple. While driving, just pull the handle onwards and the paddles will be automatically placed for the relaxed ride. When you want to get back to the previous state, just push the handle and the back supporting seat outwards and you will be on your desired position.
