An oxygen cylinder smashed into a biker after dropping from a transport truck in eastern China.

The dramatic video, shot in the county of Pujiang in Zhejiang Province on March 9, shows two oxygen cylinders falling from a transport truck after it turned a corner.

An over 50kg cylinder's valve broke and the oxygen inside fired the cylinder away, knocking a biker over.

The biker named Zhang suffered fractures to her right hand and left leg and is still hospitalized for treatment. Since she wore a helmet, her head was not injured and she is not in life-threatening condition.
