The Manhattan man stabbed in the head by an e-bike rider wearing an Uber Eats backpack Thursday told The Post the beef started after the two-wheeler nearly ran him over in a crosswalk.

“I said to him, ‘Yo man, you almost hit me man, the bike lane is over there. They are in court now fighting for bike lanes,’” Raymond Shaw, 57, said on Friday of the fateful encounter on 8th Avenue outside the Port Authority around 1 p.m.

He said he assumed that was it for the dalliance — until the unidentified e-biker came back and spit in his face.

Once the cyclist pulled out a knife, Shaw began to record on his phone.

But the man put the knife away, so Shaw put his phone away and lobbed his own loogie — and his rival hopped off the bike and re-drew the knife.

“He jumped off his bike so I started backing up on to the curb and slipped,” Shaw said. “The only punch I felt was to my head I didn’t know I was bleeding.”

“I was going to Popeye’s to have lunch, to get some chicken but it never happened,” he said.

The perp fled the scene and remains at-large.

Uber couldn’t say whether the rider worked for them without a name.
