I haven’t seen one of those before, and I honestly do not know what they are called. But looking at those seats, the first thing that came to my mind was: Are they safe? I wouldn’t dare going up there in those tiny seats. But perhaps, I’m just afraid of the height?
We visited at a time when these were not running. Otherwise, I would have been able to see whether there are more security measures or this is how people ride on them.
