The teen was riding the green bike when he was hit.

A 17-year-old cyclist was fatally hit by a tow truck in Staten Island on Tuesday — the 16th bike rider killed on New York City streets this year.

The boy was riding his green GT mountain bike alongside his brother eastward on Castleton Avenue in West Brighton around noon when he ran a red light at Clove Road, police sources said.

The teen slammed on his brakes and fell off his bike — then was hit by a 38-year-old driving a flatbed tow truck, sources said.

The boy was rushed to Richmond University Medical Center with serious injuries but could not be saved, according to authorities.

His brother, who was able to stop in time, was unharmed, police said.

The driver of the truck, registered to L&S Towing, remained on scene. No arrests had been made as of Tuesday afternoon and police were still investigating.

L&S Towing declined to comment.

The teen’s death comes amid a spike in cyclist deaths this year. He is the 16th bike rider killed in the Big Apple in 2019 — up from seven deaths in the same period in 2018, according to the NYPD.
