Cycling infrastructure needs to go hand-in-hand with bike share. If you plop down a bunch of bike share stations and don't make the necessary improvements to encourage people to cycle, people will likely not feel safe and won't use the bikes. This is the case in Rome, Italy where there were many bike sharing stations--empty. And it wasn't because they were all being used. There's no bike infrastructure in Rome and it's not a particularly bike friendly place. The bike share stations were plopped down and it didn't work.
Maybe Calgary will be different. I've never been there, but I assume that it's not as densely developed as Rome, and the streets are wider. Rome has to accommodate millions of cars in limited street space. It's hard to fit bikes, too. I did see a fair number of people getting around on bikes, but they were not bike share bikes. But really, Rome isn't like Paris, where the bike share and the infrastructure together resulted in a fantastic bicycle friendly city--a total turnaround. It can be done.
