I think a combination would work best on a MUP, ring bell, then call out, "passing on your left". The bell gets their attention, so they actually hear you. "BICYCLE passing on your LEFT" also makes an assumption, and that is that everyone you come upon has a decent understanding of English, this is not a given in a lot of major cities.
