That’s one way to beat traffic.

An newly viral video captures a brazen gang of minibikers rolling their rides onto a crowded subway train.

The clip, posted by the popular @SubwayCreatures Instagram account, shows three men line up single file on motorbikes as they attempt to board the F train at the 47th-50th Street Rockefeller Center station.

As two of the men walk their pint-size bikes into a subway car, one onlooker can be heard muttering, “that’s absurd.”

The third rider then motors his slightly larger bike along the platform — nearly hitting a commuter — before driving into a separate train car in front of gobsmacked straphangers.

The NYPD and MTA said they were looking into the incident after the video went viral — but had no idea when the stunt took place.

Citizen cameraman Connor Bell told ABC7 he took the video at around 6 p.m. on Dec. 11 on the Queens-bound platform of the Midtown station.

Fellow straphangers told The Post on Monday they found the bikers “disrespectful.”

“It’s annoying enough when people take their regular analog bikes on the train, but I guess that’s considered OK for most people, so whatever,” said Mitch Hurwitz, 24, of Forest Hills.

“Motorized bikes? Come on. Like, why not carry on a grand piano while you’re at it?”

Another rider gave sarcastic “props” to the “brazen” two-wheelers.

“I’m just amazed they got their bikes down there in the first place,” William Hu, 21, of Kew Gardens, said.

“Aren’t there supposed to be cops in every station? Or did the anarchists succeed in getting rid of them?”

MTA rep Aaron Donovan said the agency did not receive any complaints about the incident.

MTA safety boss Patrick Warren said riders should alert cops if they see another stunt like this on the subway.

“This is not only alarming for other passengers but it’s completely unsafe,” he said in a statement. “Motorized vehicles pose a hazard to our customers and are banned in the subway system.”
