Zhang Yali, 49, tests a giant bicycle designed and made by him and his friends outside a rented warehouse in Jilin, Jilin province, China, December 25, 2011. The 3.2-metre-high and 5.5-metre-long three-seated giant bicycle, weighing over one tonne, cost Zhang more over 20,000 yuan (3,156 USD). Zhang spent two months making this bike as a gift for his son, a 25-year-old part-time cartoonist currently living in Shenzhen, Guangdong province.
