A 47-year-old member of the 69ers Motorcycle Club was critically wounded by a gunman on Staten Island on Sunday, police said.

The man, whose identity was not immediately released, was shot in the neck near the group’s clubhouse on Hardy St. near Roff St. in Stapleton about 10:30 a.m., cops said.

An argument preceded the gunplay, but the details of the dispute were not immediately clear, cops said. It was not known if the man’s membership in the motorcycle club, which traces its roots to 1960s Brooklyn and has charters along the East Coast, was related to the attack.

“Motorcycles came up then I heard a boom,” said a woman who lives on the block and declined to give her name. “If this is a gang rival thing, now I’m worried about the kids being outside. Who knows what can happen?”

The victim was taken to Richmond University Medical Center in critical but stable condition, cops said.

The club bills itself on its website as one of the oldest of its kind in New York.

“This is not a club for the faint of heart, nor are we weekend warriors,” the group’s website states. “This is our lifestyle.”

Several members remained inside the clubhouse in the hours after the attack.
