The cyclist is shoved with such force that he falls from his bike into the ditch below. The fall looks traumatic, and the cyclist may have sustained injuries.
You can hear laughter in the video after the cyclist hit the ground.
The video was posted with the words "This is the new challenge boys," however the Facebook page's author, has denied that the video is his.
The video has already had 383,000 likes on the Facebook page on which it is posted, however many people also criticised the video, and questioned how anybody could find it funny, when what appears to be an innocent person is viciously attacked for no reason other than for the perpetrators entertainment.
People have reacted angrily to the video on social media:
"Do people not realise how dangerous this is if the cyclist is going even at a slow pace it can cause serious bodily harm. People need to cop on."
"The only way this would have been funny is if he missed and fell out of the car."
"What would they do if that person had heart problems and had a heart attack from fright? Or they had special needs and it severely upset them? "
"Would have been funny if it was one if these idiots on the bike and the other gobshite fell out the window, or got a smack of a branch This assault on a stranger is bang out of order & I hope karma bites you hard. On the bollix."
The Daily Mirror posted a similar video in June, with the article disturbing footage captures laughing yobs shoving cyclist off bike from moving car.
The appearance of this second video, which appears to have been filmed in Ireland, hopefully does not mark the beginning of a worrying online trend, which could easily end in disaster.
