The machine: Zweistil bike
Status: Concept, Thesis project
Product Designers: Daniel Knuepfer & Stefan Wallmann, Anhalt University
The Zweistil Variable frame bike is undoubtedly a fresh concept that you’d fall in love with at very first sight. Daniel Knuepfer and Stefan Wallmann have introduced this concept bike with an adjustable frame.
The Concept
A lever locking the frame on the handle bar of the bike and adjustable springs brings the rider to an upright position, depending upon his/her weight. It facilitates the rider to lean forward or backward while on the move. Therefore, it gives the rider the flexibility to choose what best suits him.
Riding down the city, sit upright, and while riding on the outer reaches just set your bike down in an easy mode. A purported improvement of this design is that its ultimate version will come with a battery and a hub-motor.
