Hundreds of dirt bikes, drag racers, ATVs and motorcycles were caught on video tearing up the streets of Washington Heights after police pulled back on enforcement, neighborhood residents charge.

Footage of the brazen “invasion,” which took place July 17 in broad daylight, reveals a flood of the vehicles loudly zooming through the neighborhood.

The crazy convoy “roared up Fort George Hill and then south on Saint Nicholas Avenue — taking up both lanes of traffic, running up on the sidewalks, zooming around cars and pedestrians in terrifying fashion,” an incredulous resident, David Friend, told The Post.

“We feel completely abandoned by the city — we worked with them to provide a solution — which worked — and they abandoned it after just a couple of weeks.”

In May, the Post documented the plight of the outraged Upper Manhattan residents, who challenged the cops to do something.

And they stepped up, Friend said.

After The Post’s coverage, the 34th Precinct “suddenly was amenable to requests that had been made for months and months by local residents,” he said, adding that for five weeks, the NYPD provided a squad car on-site on weekend evenings and placed barriers to make it harder for drag racers to gather and “do donuts.” 

“This didn’t completely solve the problem, but it made a big and noticeable difference which was recognized by everyone in the area,” Friend said. “Then, all of that stopped with no notice and no apparent reason.”

Neighborhood resident Eileen King echoed Friend’s sentiments.

“In May we were promised and were given a patrol car that blocked Fort George Avenue  and another car on Amsterdam [Avenue] and 190th [Street] and that prevented the motorcycle rallies with souped-up cars going in circles for hours,” she said, noting, “At the June 30th [community] meeting we were promised that this would continue.  Not so!

“Clearly there is serious breakdown in public safety when 100 motorcycles can race up a hill and take over public streets and sidewalks. It is also clear that this is an organized activity facilitated by the Internet. The size of the invasion also paralyzes any police response.”

The Fort George Area is very attractive to motorcycles, motorbikes, three-wheelers, and ATVs because the north/south avenues are wide, and some border a wooded park, residents said.

Police have told the community during meetings at the station house that cops are “frustrated, understaffed, that they must give priority to more serious problems and crimes,” said residents, who noted police have said they won’t risk endangering others by chasing the wild bikers.

The NYPD said citywide seizures of the marauding vehicles have increased a whopping 92 percent this year, to 2,646 through July 18, compared to the same period in 2021 when 1,379 were taken.

The NYPD insisted it’s still “aggressively pursuing every method to rid our streets of illegal dirt bikes and ATVs.”

“We strongly encourage residents to call 911 so that the groups can be tracked and the NYPD can alert adjoining precincts,” the department said in a statement. “If an NYPD officer can safely stop any of the motorcyclists and they are driving illegally, the motorcycle will be confiscated and appropriate police action will be taken by officers at the scene. … The end result must ensure the safety of our citizens while ridding our streets of this menace.”

City officials crushed nearly 100 dirt bikes last month, with Mayor Eric Adams saying he’s determined to eradicate the illegal vehicles from local streets.
