Vincent Graziano always feared he’d get hurt by the Coney Island’s famed Cyclone roller coaster, but he never imagined it would happen while he waited in line.

The former Brooklyn resident is suing the city and the operators of the rickety relic, claiming he was struck in the neck with a 5-inch long metal bolt that shot off the ride in March 2018. “I was stunned and shocked,” Graziano, 42, told The Post.

“I thought somebody hit me with a weapon. I got dizzy, and as I was trying to get my bearings I saw a piece of metal that fell right next to me and I realized it bounced off my neck.”

He added: “I was shell-shocked, and people were yelling at me to lay on the floor, and I didn’t know what was going on.”

Graziano was taken by ambulance to Coney Island Hospital, according to his suit in Brooklyn Supreme Court, for what he called “bad headaches” and “pain in the back of my neck that almost made me cry.”

His complaint names the city and the owners of the amusement park and ride, seeking unspecified damages.

City Law Department spokesman Nicholas Paolucci said he had not seen the complaint and declined to comment.

“The scariest thing about the Cyclone should not be waiting in line,” Graziano’s lawyer Seth Nadler said.

Central Amusement International, Cyclone Coasters and Luna Park LLC could not be reached for comment.
