Zweistil is a bicycle with a special frame that can be transformed during the ride. By simply unlocking and leaning backwards, the rider can achieve a recumbent position that provides both ergonomic and economic advantages. From this recumbent position, it is possible to lshift the riders weight forward to go back to the normal position again. Here, the rider can travel through heavy traffic with confidence, having both good overview and best maneuvering capabilities.
Key element of the frame is an adjustable, blockable oil-spring that provides both the blocking funktion of the frame as well as support to reach both positions safely.
