Dramatic security camera footage of a motorcyclist sliding on a road for 20 metres after falling off his bike.

In the clip, which was captured in Karamay, Xinjiang Uygur Autonomous Region on July 31, the motorcyclist approaches a junction at considerable speed.

Suddenly a car turns in front of the biker and he falls as he attempts to avoid the vehicle.

The biker's momentum sees him slide along the tarmac - narrowly avoiding the car - for twenty metres.

He survived the crash with only minor injuries.
