Former New York Rangers hothead Sean Avery was found guilty of criminal mischief Thursday for using a scooter to hit a car that was blocking a bike lane in 2019.

The forward, 42, was sentenced to time served in Manhattan court after a truncated two day trial.

Avery — a fierce protector of bike lanes — was in court for bashing the driver’s side door with his scooter at East Eighth Street and Broadway in Greenwich Village on Feb. 23, 2019.

He hit the car belonging venture capitalist Jonathan Schulhof, who testified before Judge Marisol Martinez-Alonso Wednesday about the incident.

The judge, who presided over the case without a jury, also issued orders of protection for all complaining witnesses.

Schulhof told the judge that “a very agitated person started screaming vulgarities at me and just telling me, you know, ‘Why don’t you watch where the eff you’re going.”

The businessman, who was in the minivan with his wife and 4-year-old daughter, testified that Avery cursed him out but “it was very startling, so I don’t really have a great record of exactly what he said.”

After the two exchanged words, Schulhof then “heard what sounded like a stick of dynamite go off, a really loud boom, and felt the car shaking.”

The attack left a “quarter-sized hole” in the door of the car next to where Schulhof’s four-year-old daughter was sitting, he said. 

Avery, who retired from the NHL in 2012, originally said he was going to represent himself in court — against the judge’s advice — but ended up hiring criminal defense attorney Jason Goldman.

Prosecutors offered Avery a series of plea deals, but he did not accept them and instead opted for a trial. He had been facing up to three months in prison.

Avery told The Post following a court appearance in June 2019: “If I need to be the poster boy for defending the bike lanes, I will absolutely do that. We need to be able to just bike in freedom.”

He played for the New York Rangers for roughly half his 10-year NHL career before hanging up his skates.
