A dirt biker's helmet camera has captured a terrifying high-speed crash.

The video shows the rider speeding down a gravel trail in Minnesota when he begins to wobble before fully losing control and falling off the bike on to the ground.

Fortunately, he was not seriously hurt in the accident.

Although the accident happened in 2016, it has only just been uploaded online.
