Yes. Tons and tons more people are biking now, especially those that weren't able before. Older and also overweight people can now bike much more easily. All anecdotal, but Denver has seemingly many more bikers.
Anecdotal as well, but Switzerland has loads of them too. I appreciate the fact that it gets more people on bikes, but I'm a bit concerned about them going on terrain way above their level (as noted above) or risking accidents with hikers.
