Colin and Ryan Pyle take off from Shanghai on their two well-kitted out BMW bikes for an epic adventure. They will cover 18,000 kilometres over 60 days in a circuit of China that has never been attempted before. Within minutes of setting off, Colin is nearly clipped by a giant bus and that's just the first in a series of unexpected obstacles that lie in wait for the Pyle duo.

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.

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. Their ultimate goal is Mount Everest Base Camp, but it's not going to come easy.

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 tyre. The journey is now in real jeopardy, with both bikes off the road and no clutch parts available in all of China.
