短语 on your bike 是一个非常口语化的表达，告诉别人快走开，不要来烦你了。因为这不是一个礼貌表达，所以使用时要注意。

例句

You want twenty pounds to clean my windows? On your bike!

Hey, on your bike – ball games are not allowed on the village green!

I told you, I don’t want to go out with you any more – on your bike!

请注意

另一个不表达让别人走开的非正式用语是 get lost, 去你的！

This is private property, you are trespassing! Get lost!
