Even in a month where eight people were killed in a terror attack, this past October, the mayor says, was the safest on record.
"We remain America's safest big city. And what happened on Tuesday didn't change that," de Blasio said.
De Blasio spent his last Friday before Election Day talking about public safety, overall reductions in crime and specific changes the city is making in the wake of Tuesday's terror attack.
"We want safety and security, but we also want people to be able to go about their lives," he said.
The city placed new barriers to block cars along the Hudson River Park bike path. They have upset some cyclists.
"I think what was originally put in in just the last day or so needs some revision to make sure people can still ride their bikes," de Blasio said.
The mayor's Republican rival, Assemblywoman Nicole Malliotakis, has been trying to poke holes in the mayor's public safety record. She is pointing to a rise in sex crimes on the mayor's watch. Rapes are up 4 percent over the last four years. Other sex crimes have risen 25 percent over the last three.
The mayor started his day at a political breakfast at Junior's in downtown Brooklyn.
Turnout is expected to be low on Election Day, and the mayor is refusing to say just how many voters he wants to see come out to the polls to feel good about the results.
"I don't have a magic number because I, like so many others, know you cannot project turnout anymore," he said.
Political consultant George Arzt says even if turnout is low, he does not think it matters.
"He wins, he wins," Arzt said. "No one is going to say, 'Well, he didn't really have a mandate.' No one is going to say that.
Still, de Blasio and his campaign team say they are focused on getting New Yorkers out to the polls.
