A 16-year-old boy was killed when he and two others riding on an e-bike were struck by a truck Monday on a Brooklyn street, cops and law enforcement sources said.

The three teens were traveling on Ditmas Avenue toward Coney Island Avenue when they were hit by the commercial vehicle as it made a right turn shortly after 4 p.m., police said.

The e-bike slid underneath the truck during the crash, according to authorities.

The 16-year-old boy was pronounced dead after he was taken to Maimonides Medical Center, while a 15-year-old boy was taken to the same hospital in stable condition, police said.

The third teen was not hurt in the crash.

The driver remained at the scene. No arrests have been made.
