My first visit to Guangzhou (once known as Canton) was in 1981. On the main boulevards one found,during morning rush hour,a number of old,broken down Soviet style buses,a few Soviet style limos and about 800,000 bicycles.
These are all pretty flat cities (although not sure about Bern) which makes a bicycle very practical for most people, and that’s key. But with the adoption of electric bikes cycling becomes practical even in cities with rolling hills. At least when the weather is good. Too bad they blew the $700 tax credit for electric out of the recent bill... although like the car companies the bike sellers would have just raised their price to compensate.
