In Iasi county, Romania, i never encounter this. The only obstacles i encounter are eithet metal poles against the drivers who park theyr cars on the sidewalk but those are not against bicycles. Round concrete shapes are also used on rezidential apartment complexes.
I think, we can call this a typically barrier=cycle_barrier with a separatebarrier=swing_gate
In CZ I found a business for producing such as the searched barrier:
Similar to the pic above, I found this:
(But I doubt that a bicycle could get through here without an accident.)
and that:
But back to the main question, how to map it.
I prefer barrier=swing_gate, because the barrier is lightly passable for bikes and won’t stop them (the intention of a cycle_barrier)! Tagging bicycle=yes (designated only when there is a sign), foot=yes and vehicle=private should fit too. Whether a horse can go through depends on how width the pass is.
