Chris Tress and his wife, Florence Tress, drive bamboo electric tricycles that they designed themselves, in Shanghai, June 25, 2012. The shell of the tricycle is made from composite bamboo boards, and the lamp is LED light. The Tresses, who are British, first saw a Chinese tricycle at a friend's wedding two years ago, and started thinking about producing the environmentally friendly and practical tricycle. Most of their buyers are foreigners because the tricycle is priced at 30,000 yuan ($4,713) to 40,000 yuan. [Photo/Asianewsphoto]
