Even Aquaman gets scared sometimes.

Jason Momoa shared his experience of riding a vintage motorcycle on the streets of New York City — warning that it’s not for the faint-hearted.

“I was scared,” he said on “The Tonight Show Starring Jimmy Fallon” Thursday night. “I was really scared.”

“I got out there, I was like, ‘Oh this is amazing.’ It was like a video game. I don’t even play video games but if I were to imagine what a video game was like, it would be driving a motorcycle in New York City,” he told Fallon.

The “Dune” actor compared the experience to a real-life version of “Grand Theft Auto” and “Frogger.”

“The people are scarier, they don’t give a crap they just walk across the street,” he went on.

“The cars at least respect the people. But it was amazing. Perfect blue-bird day, just a little bit of a chill and I’m with my friends and I’m riding in New York. And just to be able to ride up to ‘SNL’ — pinch me. I just wanted to do all the cool stuff.”

Momoa was snapped riding on the motorcycle Monday, just days before his “SNL” hosting gig in promotion of his latest film, “Aquaman and the Lost Kingdom.”

The -year-old Hollywood star was spotted at the intersection of Bowery and E. 3rd Street outside of The Bowery Hotel as he was seen firing up his chopper.

He even looked the part — opting for a black leather motorcycle jacket over a gray top with black combat boots.
