Some lucky Brooklyn residents walked away from a giveaway with free sunglasses, water bottles and even bikes.

Sponsored by the drink brand Spiked Seltzer, the company gave away 20 bikes as part of a promotion for the looming L train shutdown.

But those who won the bikes didn't get them easily -- one winner stood in line at the Willamsburg Hotel for about seven hours.

Though many walked away empty-handed and sweaty from the high temperatures, the promotion rolls on Wednesday and Thursday.
