The biker who may never walk again, Ed Mieses, is the one hit by the car as it sped away, his wife Dayana said.
He suffered broken legs, fractured ribs and spine injuries, according to his family.
Mr Mieses, known as Jay Meezee, is an aspiring rapper from outside Boston, and he and his wife have two teenaged children.
"There's no hope for his back," Mrs Meises told reporters outside hospital.
"They crushed his spine.They broke it in two different places, so he will be forever, forever paralysed."
"My husband got off his bike to help the guy," she said of the confrontation.
"When you look at the video you can see he (the driver of the car) is running over something. It's not just a motorcycle, it's a human being that was under there."
