Here's another:
Q: Have you ever ridden a bike?
A: Yes, I have.
Q: When did you last ride a bike?

It is very common to move from a present perfect that signals the past without being specific to a past event that is specific. This happens all the time in English. In fact, this is one way the past perfect versus the simple past is taught to ELLers.
Q: Have you understood what I am saying?
A: Yes, I have.
Q: How did you understand it?
A: I understood it because your explanation is [or was] pretty clear.
