"If something happens, you stop right there. It's an accident. You think and stop. You don't keep reacting on," he told CNN's Erin Burnett on Wednesday.
But on CNN's "New Day" Thursday, Davis said, "Two wrongs don't make a right" and said it was clear the SUV driver was afraid.
"If I was in his shoes, I'd be scared," he said.
No charges against driver
Police have not said that they are seeking any charges against Lien.
But they arrested Christopher Cruz, who is seen slowing in front of the Range Rover before he was bumped.
Cruz, 28, was in court Wednesday on misdemeanor charges including reckless driving. Cruz's attorney told reporters that his client is not guilty.
Cruz was to be released after posting $1,500 cash bail and a $15,000 insurance bond. In addition, his license was suspended, and he was ordered to surrender his passport.
"His motorcycle was struck, and he stood right there," Cruz's attorney H. Benjamin Perez said. "He never assaulted this man. He never tried to assault him in any way. And he does not know any of the other motorcyclists who were involved in this beating."
A second arrested biker was released Wednesday when authorities determined that he may have been trying to help.
Allen Edwards, 42, originally faced charges of reckless endangerment, criminal mischief and menacing, police said.
But that didn't mean prosecutors were done.
"Prematurely charging individuals with low-level crimes does not further the goals of the investigation and could weaken the cases we expect to bring against the perpetrators of serious crimes," said Karen Friedman-Agnifilo, the prosecutor who is overseeing the case.
"After we investigate the facts and each person's individual actions, we will know what charges can be supported by the evidence. There is still a tremendous amount of investigation to be done."
The New York Police Department released images and asked for the public's help in identifying and locating suspects.
NYPD detectives have interviewed the motorcyclist whose helmet cam captured the confrontation, according to Deputy Commissioner John McCarthy. They tracked the unidentified biker to his home in Bellport, Long Island, and have the video.
Police are also looking at a 2011 video that shows a separate case of biker violence. In it, riders appear to surround and antagonize a motorist.
Law enforcement officials said they are examining the footage frame by frame, looking for possible patterns.
Mieses' family says the real victim of the confrontation is the hospitalized biker.
"All of his ribs are fractured. His lungs are so badly bruised that he's still on a ventilator," Yolanda Santiago, his mother, told CNN affiliate WCBS.
His wife, Dayana, told CNN affiliate WBZ that Mieses got off his bike to help the SUV driver.
"And whatever he did, he got scared, he peeled off, and he paralyzed my husband on the way," she said.
At the vigil Wednesday night, the attendees raised almost $400.
