China was once known as the “Bicycle Kingdom”. Now, a young US man, David Wang, living in Beijing is using pieces of bamboo to replace(代替) parts of bicycles.
Two years ago, David opened the Bamboo Bicycle Beijing workshop in Langjia hutong. They cut and shape bamboo into bicycle frames(构架). After connecting the pieces with special glue, they join wheels and other parts together.
After graduating from university, David came to China to continue his study. He has lived in China for more than 6 years and loves the city's ancient hutongs. However, he found people threw old bicycles everywhere in hutongs. “Beijing is becoming a big graveyard(墓地) of bicycles，” David said. He began picking up the given­up bikes and “saving” them, repairing, repainting, and renewing them.
Then one day he found a really old bicycle, which could not be “saved” in usual ways, so he began thinking of better materials to replace the frame. Bamboo came to his mind.
He searched online, and after three months of research and tries, communicating with factories and experts, he made his first bamboo bicycle. “It was amazing! It really works！” he recalled.
The bikes are not for sale—they're to encourage a love of cycling among people who live in Beijing. David hopes bamboo bicycles can create “a little bit more different culture in Beijing”．
