Literally everywhere? Quais, bd Sébastopol, Grands Boulevards, Rivoli, Bastille are places you can barely cross due to the amount of bicycles.

I've also biked and seen others on the Maréchaux, through all arrondissements. Same in the Petite Couronne suburbs, and i have friends living in faraway places that have well bike parkings at their train stations.

Concur. I remember sitting jet-lagged in a cafe at the Place Bastille watching all the cyclists go by. I was impressed by the guy who cycled with a phone to his ear, until I saw the woman with a phone to her ear and a cello on her back.

Three weeks ago I walked from Opera to Eiffel tower and while there were some cyclist it was only a few and nothing compared to like the netherlands.
