Bike messenger in road-rage tragedy has lengthy rap sheet

He’s hell on wheels.

The bike messenger involved in the road-rage crash that maimed an English tourist has a long rap sheet that includes 22 arrests — including a recent bust for threatening to decapitate a man and kill his family, The Post has learned.

“You don’t know who you are messing with! I will stab you! I will decapitate you! I will kill you and your family!” Kenneth Olivo, 40, allegedly snarled in a McDonald’s at 545 Sixth Ave. on April 28.

“You don’t know what I have up my arm,” he said, pointing to his sleeve and implying that he had a knife to threaten a man who had objected when Olivo kicked a dog, according to authorities.

Olivo later pleaded guilty to a menacing charge.

The rogue cyclist has not been charged in Tuesday’s crash, but sources said investigators are still combing through video to determine if any charges should be filed against him.

VICTIM DETERMINED TO CARRY ON WITH HER LIFE

In addition to the menacing incident, Olivo is also allegedly a chronic turnstile jumper who intimidates straphangers into giving him free MetroCard swipes.

On Oct. 25, he was blocking turnstiles in the West Fourth Street/Sixth Avenue station and issued a violation, one of three busts for aggressively panhandling MetroCard swipes since July 2012.

In February 2012, he was busted for allegedly openly drinking a can of Four Loko in front of 77 Eighth Ave., and in August 2011, he was arrested for allegedly drinking a can of malt liquor at St. Marks Place and Avenue A.

In February 2011, he was charged with assault for allegedly punching his roommate in the face in their Brooklyn apartment in a dispute over using the telephone.

A month earlier, he was charged with larceny for allegedly swiping wine from a cafe in Penn Station.

He was busted in November 2010 for allegedly urinating on a moving subway train near Seventh Avenue and West 34th Street. He has other busts, for alleged grand larceny, assault and other charges, five of them sealed, dating back to July 1994, sources said.

Olivo, who said Tuesday’s crash was “like a damn movie,’’ had gotten into a road-rage fight with cabby Mohammed Faysal Himon, 24, of The Bronx.
