Police have released surveillance video of a man riding an e-bike who they say is suspected of sexually assaulting at least three women in Manhattan since May.

The two most recent incidents took place just an hour apart on July 16.

According to the NYPD, in one instance, a 23-year-old woman was walking at around 4 a.m. near Central Park West and West 82nd Street when she was accosted by a stranger who came up to her from behind and yanked her to the ground.

“After a struggle ensued, the individual held the victim down and digitally penetrated her genital area,” cops stated.

The attacker fled on foot and was later seen traveling on an electric bicycle.

The victim suffered abrasions and was taken by paramedics to Mount Sinai Morningside to be examined.

An hour later, a 28-year-old woman was walking in the area of Avenue A and East 4th Street when a stranger on a e-bike approached her, dismounted and grabbed her.

Police said the attacker allegedly told the victim that he had a knife, then pulled her to the ground and exposed himself to the woman before forcing her to perform oral sex on him.

The culprit was last seen pedaling away eastbound on East 4th Street.

Two months earlier, on May 15, a 26-year-old woman was riding her bike at around 4:30 a.m. on the Manhattan Bridge walkway when a man approached her on his electric bicycle.

Cops said the stranger got off his bike and grabbed the woman’s hair from behind. He then displayed a knife, pulled down his pants and forced the woman to perform a sex act on him, before fleeing the scene.

Police previously released a sketch of the wanted man, who appears to be young and wearing a hoodie.

As of Thursday afternoon, no arrests have been announced in connection with this case.
