My Rad City3 Step-thru motor clunks when hitting rough spot or during shift.
I believe it comes from the gear cassette slap and resonates.
Is this common or is there a fix? thanks

It's shifting OK? If so the cassette is probably fine. They will start clicking a little when worn, but that's the only noise I'm aware of from that.

Not grinding or skipping a tooth occasionally? That would indicate the need for some maintenance. A derailleur adjustment at minimum.
 
Wiggle the largest rear gear back and forth. If it moves enough to hear it that’s the problem.
