Two thugs viciously attacked a biker in The Bronx and tried to make off with his motorcycle, according to police video released Tuesday.

The footage shows the 24-year-old victim stopping at a red light on the corner of Valentine Avenue and East 184th Street around 6:30 p.m. before the two men run up to him and punch him off his dirt bike.

The victim at one point gets beaten with his own helmet as the men brawl in the middle of the busy street.

One of the men then tries to flee on the motorcycle but is apprehended by responding officers, cops said.

Kirk Mcgowan, 23, was charged with robbery, menacing, assault and criminal possession of stolen property, police said.

His cohort, who is still on the loose, is described as in his 20s, 5 feet 9 inches tall and weighing approximately 180 pounds.

The victim was not seriously injured.
