Shocking dashcam footage has captured the moment a cyclist was thrown from his bike after being hit by a car south of Perth on Monday morning.

The footage, taken on Safety Bay Road near Rockingham about 7.45am, shows a cyclist travelling in the bike lane on the side of the road before a white Toyota attempts to pull into the intersection, seemingly unaware of the rider's presence.

The cyclist is hit, and collides with the windshield of the car.

A witness submitted the footage to the Dash Cam Owners Australia Facebook page and said the cyclist was "shaken up" but had walked from the crash unscathed.
