Last week during Salone de Mobile in Milan, Bleijh Concepts and Design showed the Sandwich Bike at the Tutto Bene Show. Currently in prototype stage, the bike frame is made of two wooden plates, and four identical 'smart cylinders'. It ships flat and can be assembled at home with a single tool. The absence of welding joints makes the frame very easy to produce, and the materials can vary according to the clientsâ€™ demand. This way the bike can be kept simple and reasonably inexpensive.
The Sandwich Bike was a big hit - so much so that someone broke into the exhibit and stole the prototype. Rather than dole out justice on the thief, your best course of action is to order one of the bikes yourself.
yeah its ss/fg related! look at the drive train. also...inspiring idea i can make that easily....but i would use metal/aluminum plates and not wood.
