The driver, who police say was frightened for his wife and 2-year-old child in the SUV, suddenly lurched forward, plowing over another rider before heading north. The cyclists pursued the driver for about 2.5 miles, until the SUV got off the highway and got stuck in street traffic.
The video showed one biker smashing the driver's window with his helmet. Police said the group then pulled the man from the SUV and beat him, although that part isn't shown on the video, which police confirmed was authentic.
The SUV driver, Alexian Lien, was taken to a hospital for stitches for his face. A call to his home wasn't returned Wednesday.
Cruz's attorney said his client wasn't involved in beating Lien or attacking his car, didn't know anyone who was involved and was simply trying to exchange driver information when he got off his motorcycle after it was hit.
The biker who was run over as the SUV fled, Edwin Mieses Jr., broke his legs and suffered spinal injuries that will leave him paralyzed, said his wife, Dayana Mieses, who said the motorcycle riders had wrongly been vilified in the episode.
At least one other biker was injured.
The motorcyclists were participating in a periodic rally in which more than 1,000 bikers head for Times Square, police Commissioner Raymond Kelly said. There were 15 other arrests, and 55 motorcycles were confiscated, he said.
