Ai Weiwei:

The bicycle is a few objects when we grew up every household has in China. When I was a child, the whole society is very poor. To have a bike is a very luxury item. And the Forever bicycle was the best brand at that time.  It's very durable and it's very practical matter and build very strong for the countryside. But in China, it's changing. More cars are being bought and the air is very polluted. So it's really related to people and citizens. And today, when I started architecture to teach the students how to build, I tell them you can build with any material, not just bricks and concrete. I said let's use daily objects to build a structure. So, after discussion, we managed to use bicycles, because you see everywhere. But you never think to use bicycles to structure something else. It's very much like the stools, same kind idea. Use its own logic to destroy itself to become something new.
