If you've ever been charged by an angry goose, you know they hiss. Not Sssss like a snake, but an open-beaked Hahhhhhh. Hiss at them like that and they scatter quickly.
I also spread my arms out, like they do their wings.
I never see them on my bike ride but I encounter them at Minto Brown park in Salem, OR when I go running there. Once I had gone off the path and tried to go around a goose (gander? dunno) who was hogging the trail. He was not satisfied though and came after me anyway. I demonstrated that, at 175 fairly fit pounds, I can defeat a goose in single combat. Yay me!
