In both cases, bike, ebike, and scooter riders seem to love sidewalks. I imagine that case 2 is legal because riding on a busy road along with cars that are going twice as fast is dangerous, but I'm wondering about case 1 in Shanghai, as well as other cities (e.g. Nanning is particularly scary for pedestrians).
It's most certainly not legal to ride a bike on Hengshan Rd:
Road sign banning bikes on Hengshan Rd.
In general, if you're in the French concession and you encounter a street with no bike lanes, assume that bikes are forbidden. Of course, there is zero enforcement if a police officer is not present.
