A pack of bike-riding men surrounded a 41-year-old woman and robbed her at gunpoint at Pier 84 in Hell’s Kitchen, cops said Sunday.

The woman told police the men circled around her around 8 p.m. on Friday in front of 555 12th Avenue when one of them pulled a gun.

The pack stole the woman’s purse containing $60 in cash, a cell phone and three credit cards, according to police.

The credit cards were used four times later that night at CVS and a smoke shop, where two of the men charged more than $640, cops said.

Police released photos of the pair who used the credit cards Sunday.
