A motorcyclist who was allegedly involved in a hit-and-run incident in Adelaide has been filmed by a witness clashing with a driver.

According to the filmer, who wishes to remain anonymous, the motorcyclist hit a car while travelling along Hindley Street and then stopped his vehicle.

In the video, the rider tries to put his keys into the motorbike's ignition but is prevented from doing so by another man, apparently the driver of the vehicle that was hit.

"Buddy I've already got your picture, there's no point (driving off)," the filmer can be heard saying in the video as the rider and driver wrestle.

"You cannot hit-and-run," says the driver to the motorcyclist.

The motorcyclist then asks for help from another passer-by, saying: "Hey cuz, help me! Help me!"

Another passer-by then chips in and says to the motorcyclist: "Why don't you wait till the police get hear?"

Motorcyclist trying to get out of a hit and run accident then pleading with bystanders to help him.

This occurred after the motorcyclist drove at high speeds and broke too late behind a turning car, colliding with the back and throwing the driver over the handlebars. The driver of the motorbike fled on foot briefly then returned to try to escape on his bike, which is what is shown in the video. Following the video he ran away on foot, after being denied use of the bike by the other man in the video (the driver of the car).

This occurred on Hindley St, Adelaide, South Australia at 4.30pm on 14/3/18.

The motorcyclist seemed to be running from something so he may've stolen the motorbike.
