As mentioned below, cycling is still a major form of transportation in Shanghai. And as in some European cities, bike parking can be a problem. 
The street rights-of-way laid out by the Europeans in the international concessions may be wider than the traditional lanes of the lilong in the older Chinese sections, but they are being asked to do more as automobiles take more space and the sidewalks have to cope with both pedestrians and parking for bikes and scooters. And the bikes and scooters are getting bigger too.
If you want a glimpse of the future of cycling in North America,
you can get a pretty good idea by taking a survey in Shanghai of the percent of ‘bikes’ that in fact are electric scooters, and scooters that are morphing into motorcycles. I’d estimate that something like 50 to 60 percent of foot-powered vehicles are in fact electrically assisted, whether manufactured that way or adapted with battery packs and gearing.
Only in places like Vancouver, I presume, do people get on bicycles for recreation and exercise. In any event, I’ll predict that our separated bike lanes, like those in Shanghai, will eventually be filled with people whose legs won’t move even as their wheels do.
