I think Jonsims has really hit the nail on the head with analysis. The problem with China is there are so many people in China, that enforcing any law has minimal effect. Over the years they have figured out the only way to make any effect on road use or habits is have an absolute zero tolerance purge. The problem with this it robs people of their freedom. Yes, banning motorcycles completely is a very effective way to stop unregistered, uninsured, unlicensed riders bag snatchers and illegal motorcycle taxis, but taking away people's freedom to ride in a city is much worse.

And it's the same for ebikes forcing licensing, registration and insurance won't work unless the police are 100% committed, and it's just not a priority because ebikes are so low on the food chain, and there are just too many of them. So what what would most likely happen is they are completely banned, and that's just not a place I want to go. It's not because I have any love for ebikes, I don't understand them at all.

China needs much better public education on road use, from inside the family, school and on TV in newspapers. What they have at the moment is 'drive civilized, walk civilized' or look what happens when you have an accident because you didn't 'drive civilized', but little underlying concept of what driving civilized actually is.
