Arben Hoti, a 31-year-old construction worker, was driving into Manhattan on the bridge's outer lane about 2:30 a.m. when he fell off his motorcycle and into the road, police and family said.
Hoti, who lived on East Third Street in the East Village, had suffered multiple injuries when first responders arrived and pronounced him dead, the NYPD said.
"Everything is going through my head right now. I don't know what to do or think. It's just so sad. We're going to miss him a lot," said Hoti's grieving brother, Adnan Hoti, 29.
Family who flocked to Hoti's apartment Thursday morning said he had been riding for about six years and was part of a motorcycle group.
"He rode a lot," his grieving brother said. "He was really experienced."
Relatives struggled to grapple with the biker's death.
"Every young kid likes to ride a motorcycle. I don't know what happened last night. I only know that it was raining," said the motorcyclist's 64-year-old father, Hasan Hoti.
"It's hard as a parent."
Although thunder storms drenched Thursday's predawn hours, police couldn't say whether Hoti's death was weather-related.
No other vehicles were involved, police said.
