A pack of rowdy bikers were caught on video pummeling a driver into the pavement of a California highway on Wednesday.

A group of about 15 bikers driving all-terrain vehicles surrounded the man’s car on Highway 101 in San Francisco Wednesday and violently tossed him to the ground as terrified motorists drove by, according to the San Francisco Chronicle.

A woman who identified herself as the victim’s sister told the Chronicle that her brother is a new father and an Uber driver in the city.

“He’s a good guy,” Natalie King told the paper. “He’s not a troublemaker or nothing like that. I don’t understand why someone would beat him up.”

A number of witnesses videotaped the brutal beatdown as it unfolded.

“I saw the male bikers surround the vehicle and started to yell, break side mirrors and also physically hitting the vehicle,” one driver told the Chronicle.

“It seemed like they were provoking the driver to come out.”

The incident was reminiscent of the 2013 beatdown of Alexian Lien — who was attacked after he ran over a biker on the Henry Hudson Parkway.

The assault took place after the bikers surrounded Lien on the highway.
