The victim was found next to his bicycle just before 4:00 a.m. on Meeker Avenue between Frost Street and Manhattan Avenue.
He had suffered trauma to the head, authorities said. He was taken to Bellevue hospital, where he was pronounced dead on arrival.
Investigators are still trying to piece together what happened and do not have a description of the vehicle yet.
The identity of the victim has not been released, pending proper family notification.
