"felgenreparatur doktor bamberg" you will find many shops that can repair your damage wheel(s).
Behind MediaMarkt(& KFC) there is a small body shop that does GREAT work(
A&N SCHOLZ) . I've used them before. They don't speak much English but they are good people. Also across the street from MediaMarkt is another body shop "Lack Doktor" that probably could do the repair too. ATU also does wheel repairs too now.
