ZWEISTIL

Variable Frame Bike

독일의 'Anhalt'대학에서 졸업을 앞 둔 '다니엘 크뉘퍼(Daniel Knuepfer)'와 '스테판 월맨(Stefan Wallmann)'의 졸작으로 선보인

변신하는 자전거 'ZWEISTIL'는 자전거의 핸들 부분의 레버를 조절하여 전체 프레임을 바꿔 기본형 자전거에서 누워서 타는 리컴번트 자전거로

3단계 형태로 바꾸어 탈 수 있는 콤비네이션 자전거입니다. 핸들의 레버를 풀고 핸들을 몸쪽으로 당기면 차체가 낮아지면서 뒷쪽 보조 안장이

등받이로 세워져 라이더가 쉽고 편하게 누워서 탈 수 있도록 하였고, 또한 등받이 하부에 배터리 팩과 전륜에 허브 모터를 장착한 전동형 자전거입니다. 프레임 자체 또한 현대적인 감각에 맞게 디자인되었습니다.

The bike is up, then the bike is down. You sit on the bike upright in the city, then set it down to cruise in the suburbs. It’s intuitive. It’s wild. It’s a thesis project. It’s got a video to go with it. It’s already mocked up. The final version will have a battery and hubmotor for a little kick in the pants. Environmentally friendly city and country transportation in one bike.

Each frame is adjusted to the weight of the rider. The rider may ride in either mode forever, but if the rider wants to switch from one position to another, they’ve just to push the locking lever and lean forward or backward. The rider may change positions while continuing to ride the bike.

Info on the mockup movie, below:This is the proof of concept mockup for a commuter bike with variable frame as part of the diploma thesis of the product-designers daniel knüpfer and stefan wallmann at anhalt university, dessau in mai 2008. In the concept, the frame can be locked by a lever on the handlebar, that feature is missing in the mockup. Also, the springs that help bringing the rider in an upright position need to be adjusted to the riders weight to balance the frame (making it possible to switch positions while leaning back or forth). these springs are too weak in this prototype, therefore the riders in the video need to push the backrest a little bit. only a very lightweight rider managed to bring himself up by simply leaning forward.

Vielen Dank, Deutschland.
