I’d noticed those hire-bikes in the background of some of your other videos. You probably know there are similar schemes elsewhere around the world (the largest being Paris and London).
In Paris people love to hire bikes to cycle down the Montmartre hill but no-one ever wants to cycle back up (the scheme operator drags them back up en masse).
We've noticed that here in Guadalajara, there are popular pickup points and other places that are popular for dropping off. That means, there are often times bike stations that are completely full or empty. It seems that they have to put a lot of effort into transporting bikes from popular drop-off stations to popular pick-up stations. I imagine it's quite a complex system and there's an immense amount that we don't know.
