It's not even a year since the Vélib' bike share programme was introduced in Paris and the city has embraced bike culture quicker than you can drink a post-dinner espresso.
Not just the Vélib' bikes, but bikes of all kinds grace the streets. They mostly use the existing bus lanes but there are many segregated bike lanes.
The most amazing thing is that all sorts of people ride. Men and women and kids. Young and old.
Even more amazing is that the traffic - normally a witchs' cauldron of automotive hell - are dealing with it. The cars stop for the bikes. The cyclists watch for the cars. It's splendid to see a big city like Paris making it happen.
