Tough Rides: China - Season 1

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. Then, heading away from the idyllic grassland and rolling green hills, they strike the world's largest traffic jam.

Ryan and Colin Pyle leave their moon-scape camping ground at Turpan and head across the salt flats to Xinjiang, China's Wild West. In a few hours, they travel from 150m below sea level to 3300m above sea level in freezing temperatures.

After Ryan has recovered from the worst motorcycle fall he's ever had, the Pyle brothers aim for Tibet on the G219 highway, passing mountains and lakes, including one of the most holy places in Asia, Lake Manasarovar.

A local Zhongba motorcycle repairman comes to the Pyle brother's rescue, managing to get the BMW bike clutch back in working order. But further disaster strikes when Colin's bike blows a tire. The journey is now in real jeopardy.
