Tough Rides: China

After surviving India's dangerous mountain roads, the Pyle's head to Amritsar, home to the peaceful Sikh Golden Temple and the volatile Indian - Pakistan Border.

Colin and Ryan Pyle are in Rajasthan, famous for brightly painted palace hotels. The first stop in the heat of the Indian desert is the world famous rat temple in Bikaner.

On their journey down the Indian south west coast, the Pyle brothers visit Mahindra's mega car factory, and Colin takes the test to become a car factory worker.

Madurai is a 2000 year old city and one of the world's oldest inhabited cities. As the journey continues north up the east coast of India, the carnage on the roads continues.

Ryan and Colin Pyle bike to Inner Mongolia, bunking down for a night in a yurt village before visiting one of China's largest wind farms. Heading away from the idyllic grassland and rolling green hills they strike the world's largest traffic jam, where some trucks are stuck for 20 days.
