Brooklyn resident Steve Greenfield said bicyclists are spinning out of control.

“I’ve been hit several times,” said the 67-year-old retiree who lives near Prospect Park.

He described a scary 2007 incident when he was knocked down by an out-of-control biker.

Greenfield said he was crossing Union Street and Grand Army Plaza near Prospect Park when he was clobbered.

“I waited for the light to change. A bike came down the street the wrong way,” he said.

“It hit me in the bag I was carrying and it spun me around and I fell on the ice. He didn’t even stop.”
