Should I work things out with the at fault driver instead of going through insurance?

I was hit by a car while riding my ebike a few weeks ago. My mother bought the bike online for me from the manufacturer. I hadn't registered the bike yet, and hence had not activated the warranty on it. I was headed home after delivering for Uber Eats with the bike all day, which is my only income source right now. I have no other vehicle.

The driver assured me at the scene that he intended to buy me a new one. I felt bad for him and made sure he understood how expensive it was. He gave me a ride home, we traded phone numbers and shook hands. His passengers were the only witnesses. The bike is trashed but doesn't appear to be totalled, but no repair person has looked at it yet. I've got some minor injuries. Basically I'd like to get back on the road, and while i'd happily take a brand new bike and some compensation for the lost income, I don't think i have the stomach to demand that if we keep it between us. What should I do?
