Yes, Paris is quite easy to cycle around. This article, though mostly about plans for new cycling infrastructure, also mentions cycling has increased in Paris in recent years along with the existing infrastructure, some of which is temporary bike lanes added during the pandemic: https://www.bloomberg.com/news/articles/2021-10-22/how-paris...

it isnt safe. you need to be careful all the time of many things. many people have serious injuries on bikes in paris. if you know driving rules, have experience riding a bike and a helmet then it becomes less dangerous but to give you an example when u bicycle on a straight line you will be allow to continue and the drivers will be allowed to turn. 50% of the drivers dont understand that you can go straight will they can make a right turn. it is really dangerous and you always need to be careful of cars turning on you. people who tell u otherwise are just drinking their koo. aid or working for lobbies

As a local, I still wouldn't recommened cycling here to inexperienced tourists.

Yes it is.
