"I have had several bicycles in my lifetime."
Does this sentence suggest that he doesn't have any of those bicycles now? or we can't tell?
He may have one, but like Bhaisahab I think he's very unlikely to have several IMO. And the sentence is not about what he currently owns.
I would say it does not imply that he has no current bicycle/s. And if he does have a bike currently, then it is, by definition, one of the ones he has had in this lifetime.
A: I like your new bicycle. Is this your first?
B: No, I've had several bicycles in my lifetime. [and this is one of them]
This is the present perfect, which is used for events etc. that are still true in the present.
"I've had three wives." Am I currently married? We can't tell.
But, as usual, people don't talk in isolated, cryptic sentences.
