Well, a long while ago in the mid-eighties, Amsterdam had the "white bikes" plan, launched by a group of activists, the idea was the same as in Georgia.
The plan failed cause people started too steal or sell the "white bikes"
Today, commercial companies use the same idea, but you have to pay for it, Ammsterdam is overcrowed with bicycles, every where you go, you see bikes.
The biggest problem are the stolen bikes, a year ago it was not ilegal and not legal to sell bikes on the street, this sounds a bit weird, but this is typical Dutch policy, its called "gedogen".
This means its actually forbidden, but the police does not charge you.
People who needed money, started to steal bikes and sell them on the street;a person who needed a cheap bike, bought it on the street, and here is the big circle; the whole city is riding on eachothers bicycles!
A friend of mine had eight bikes in one year, all been stolen!
This year its forbidden to sell bikes on the street in Amsterdam, hopefully, the number of stolen bikes goes down.
