Honestly, if I had needed to make a professional decision about it, I might have gone with translations as well. It's a tough spot to be in.
In season one they kept "Mumen Rider," though the joke doesn't really translate well without context regardless. Mumen Rider is a play off "Kamen Rider," a famous superhero series in Japan. It also literally means "Licenseless Rider," hence why he rides a bike to get around.
