A Brooklyn cyclist died days after be blew a red light and was hit by a driver over the weekend, police said Thursday.

Kenichi Nakagawa, 22, was riding his bike south on Brooklyn Avenue near the corner of Dean Street in Crown Heights — just blocks from his home — around 5:24 p.m. Saturday, as a 66-year-old man behind the wheel of a Toyota Sienna was driving east on Dean Street with the green light, police said.

The front bumper of the car hit Nakagawa and knocked him onto the street, where he sustained a head injury, cops said.

The driver stayed on scene and was not charged because he had a green light, authorities said.

Nakagawa was brought to Kings County Hospital and was placed on life support but he succumbed to his injuries Tuesday.

A colleague who had been to visit his friend in the hospital told The Post Nakagawa looked “like he could wake up [at] any time” and “couldn’t think” when he found out his pal died.

He said Nakagawa had a passion for healthy food and was a chef at a restaurant.

“He brought Ethiopian spice one day, we were talking to one day try [to cook with] Ethiopian spices, but now he’s not here,” the friend said.

The friend, who didn’t want to give his name, added Nakagawa was a “very kind” and a “very honest, straight person.”

“One time I was complaining about someone, and he said, ‘forgive, just forgive,'” said the pal.

“He was young, but his soul was very mature…. He wanted to be a tattoo artist. I was going to introduce him to a tattoo artist, but now….” the friend added before trailing off.

Roy Messiah, Nakagawa’s neighbor, called the news of his death “heartbreaking.”

“He was a pretty nice guy. He always waved when he comes and goes,” the 56-year-old said.

Nakagawa’s landlord said the chef would sometimes ride a unicycle and he was a very devout Coptic Christian.

“I’m sorry he ran a red light. I don’t know why he did that. I never think that would happen,” the landlord said.
