The city streets are crawling with menacing pedicab drivers — and the de Blasio administration isn’t doing a thing about it, The Post has learned.

Not one rickshaw driver or pedicab business has gotten a violation this year from the Department of Consumer Affairs, according to the most recent data, as of May 15.

Only four of the drivers were ticketed at the same point in 2014, during Mayor Bill de Blasio’s first year in office — far fewer than the 97 violations issued under then-Mayor Mike Bloom­berg for that period.

“Bloomberg really cracked down,” said one pedicab driver, Cengiz Ozcelik, 42, of Bay Ridge, Brooklyn. “I’m thankful to de Blasio. We used to get mad tickets. But not under de Blasio.”

Pedicab businesses also have gotten a big break under the new administration — from 15 summonses in 2013 to just seven in 2014.

Akiva Abdurahmanov, a 33-year-old tourist from Israel, said in Central Park that pedicab drivers keep harassing him and his family on their vacation.

“They approached us and asked, ‘Do you want a ride?’ I asked how much, and he said, ‘For 40 minutes, it would be about $120,’ ” said Abdurahmanov.

Pedicab drivers are required by law to have clear, consistent rates posted on visible signs.

Carlos Roman, 46, who works on Central Park South, said some drivers are out there every day trying to overcharge tourists.

“One tried to charge a lady $200 to go from 59th and Sixth to the Sheraton on 53rd,” he said. “I turned to the lady and said, ‘Grab a cab or walk.’ They hurt tourism.”

The Department of Consumer Affairs is blaming the court system for the lack of enforcement.

The city lost two appellate court decisions on pedicab cases in February and June last year, when judges challenged its right to randomly stop pedicabs.

“These cases significantly challenged our ability to inspect and enforce against pedicabs,” the DCA said in a statement.

The agency said it has worked with the Law Department and plans to start inspections again soon now that the weather is warm. It added that it works with the Parks Department and NYPD on enforcement.
