A
cyclist may also say "
On your left" or "
On your right" as applicable, to let you know they're approaching you. This is especially true if they don't have a
bell on their
bicycle. The disadvantage to this approach is that the
pedestrian only hears "left" or "right" and moves that way, which is again, into the approaching cyclist. Just be informed that if you hear one of these phrases, someone's coming at you from the corresponding side, and you should go the other way to avoid them.
Generally, this is only applicable on bike paths or sidewalks, where it's considered appropriate for cyclists to ride on the sidewalk.
