A Citi Bike-riding man was shot dead outside a Brooklyn housing development Saturday, according to authorities and police sources.

The 47-year-old victim was found in the rear of a Marcy Houses building at Marcy and Park avenues in Bedford-Stuyvesant around 9:30 a.m., cops said. He was pronounced dead by first responders.

His bloodied body was covered in a white sheet, and the Citi Bike lay next to him on the sidewalk as investigators gathered at the scene.

No information about suspects, or a motive, was immediately available.
