Brooklyn’s worst neighborhoods have become dumping grounds for Citi Bikes — which locals are stealing from docks in nice neighborhoods in Manhattan and using as disposable one-way rides home, police sources say.

Cops have discovered more than 67 of the bright blue cruisers abandoned on streets and sidewalks in East New York, Brownsville and Crown Heights, the sources said.

“The first time we saw it, I thought it was kinda funny,” one police source said. “We can only assume they’re taking them for joyrides or that the crook would rather take a bike than a train ride home.”

Bike thieves sometimes wait for riders to improperly dock a bike in Manhattan then snatch it, ride it home and ditch it in Brooklyn, the sources said.

The problem has gotten so bad in Crown Heights that cops are out of garage space to store them, another police source said.

To solve the problem, they’ve started stashing the bikes in a jail cell — while they wait for Citi Bike officials to pick them up, the source said.

“We were putting them in the garage, but there wasn’t enough room — so we moved them to the back cell,” the source said.

At least 12 of the abandoned bikes turned up in Brownsville, 15 in Crown Heights and 40 in East New York, officers said. At least five thieves were arrested for riding the stolen bikes in Bedford-Stuyvesant, the sources said.

The thefts are also going strong in The Bronx.

At least two Citi Bike crooks have been arrested in recent weeks — including one cyclist who painted a bike orange to disguise it, a Bronx police source said.

But cops spotted the Citi Bike “sticker” on the orange ride and charged him with grand larceny, the Bronx source said.

The bike-share program features docks in several northern Brooklyn neighborhoods, including Williamsburg, Fort Greene and Dumbo, but does not include most of southern and eastern Brooklyn.

Riders who check the bikes out and don’t return them are charged $1,200.

But Citi Bike spokeswoman Dani Simons had no information about how many total have gone missing — or what Citi Bike does if a bike is swiped by someone who has not checked it out.

“In general, the bikes are locked in the docks . . . Nearly all of our bikes are back in our system within 24 hours,” said Simons.
