"He managed to come out of it with what you could only describe as injuries from a car crash, literally, multiple fractures of bones in his elbow and in his back," he told Radio.com.
"But he's doing OK."
Bono is currently in recovery in Dublin, he added.
Since his accident, Bono has been forced to sit out of a number of U2 live appearances, including a headlining gig for World Aids Day in New York earlier this week, where he was replaced by substitute frontmen Chris Martin and Bruce Springsteen.
The "high energy bicycle accident" in Central Park left him with a "facial fracture involving the orbit of his eye" and a bone "tearing through his skin".
Dean Lorich, Bono's Orthopaedic trauma surgeon, told Rolling Stone magazine: "He was taken emergently to the operating room where the elbow was washed out and debrided.
"A nerve trapped in the break was moved and the bone was repaired with three metal plates and 18 screws."
In true Final Destination style, the incident happened days after Bono narrowly avoided a mid-flight disaster when the door fell off the private jet he was travelling in, scattering his and his friends' luggage somewhere over Germany.
The singer was making a two-hour trip from Dublin to Berlin on board a Learjet 60 D-CGEO with four friends heading to the Bambi International Music awards when the accident apparently took place.
When the aircraft reached the German coast, the tailgate at the rear of the plane became detached.
"He was extremely lucky, the plane could have gone down," a source is quoted in the Irish Daily Mail as saying.
