A Greenpoint motorcycle club is going full-throttle for Puerto Rico hurricane relief.

Members of the Unknown Bikers MC say their Puerto Rican roots run deep.

"They're starving over there," says Chez Sanchez. "If we could help, whatever we could do, we're going to continue helping."

The club began by crowdsourcing supplies -- gathering donations of food, water and medical supplies from the community.

Then they gave the donations to the Coney Island Youth Organization, which will pass them on to the Coney Island Tabernacle to be shipped to Puerto Rico.
