Cops are slamming the brakes on dangerous Central Park cyclists — as the mom struck in the park last week died.

Police hit riders with 103 summonses during a weekend crackdown that was launched a day after Jill Tarlov was hit by a speed demon on a high-per­formance bike, according to NYPD stats.

Tarlov, of Connecticut, died from her injuries on Sunday night, her family announced Monday.

Between Friday and Sunday, 29 riders were caught failing to yield to pedestrians, 26 blew red lights and 30 were ticketed for wearing headphones, according to the NYPD.

Officers wrote 42 of the tickets in a “targeted enforcement area” along West Drive from West 60th to West 65th streets — the busy area where Tarlov was hit on Thursday.

Fifty-six summonses were doled out on Friday, 27 on Saturday and 20 on Sunday.

Cops were already on a record ticketing pace in the park before the bike blitz. They wrote 468 total summonses — including 233 for failure to yield to pedestrians — between Jan. 1 and Sept. 14.

That is a 210 percent spike from the same period in 2013, when 151 summonses were issued.

“I follow the rules,” parkgoer Dr. Jonathan Schrott, 59, said Monday of the amped-up enforcement. “And I think they should crack down on everybody who breaks the rules. That includes pedestrians.”

But cyclists were still riding rampant Monday. During a 30-minute span, a Post reporter witnessed 67 of 69 park cyclists pedal right through a red light. None was ticketed.

A 37-year-old cyclist who only gave a first name, Allan, was stopped by police at around 4:15 p.m. for running a light on West Drive near West 65th Street — just north of the crash site.

“I didn’t know they were cracking down,” he said. “Makes sense, people are dying. It’s crazy, nobody knows the rules.”

But he also admitted bikers’ routine recklessness.

“Everyone goes through reds,” he said.

Lina Petion, 47, who lives on West 72nd Street, said the crackdown was needed to make Central Park a safer place.

“This is a park, you have to feel safe,” she said. “There are kids here.”

Knowles Johnson, 44, who was biking through the park, stopped at the scene of the accident to leave flowers and pay his respects.

“I’m a cyclist some days, I’m a pedestrian some days — but I’m a father and a son every day,” he said.

Cyclist Shelly Mossey, who also left a bouquet of white roses at the site — as well as a sign that read “NYC cyclists care” — put some of the blame on clueless pedestrians.

“They don’t need NYPD — they need pedestrian crossing guards and some common sense,” Mossey, 60, sniffed. “Hopefully this will wake the whole city up. That woman did not need to die.”

Tarlov, a mother of two, was left brain-dead from Thursday’s crash and spent the weekend on life support.

Jason Marshall, 31 — who witnesses said was speeding on his $4,000 Jamis Eclipse bike — has not been criminally charged.
