I wonder how much they will have to protect against recklessness of the e-bike owners? For example, against the end user sourcing substandard cells, and combining them in inadvisable ways.

I don't have a good profile of e-bike owner behavior about maintaining their own equipment, but what I can say is fewer than 1/5 of e-bikes will stop on red at a 3-way intersection near me (when cars are stopped in the parallel lane, and pedestrians are crossing).

We also see a lot of riding on sidewalks, at speed, to bypass red lights and traffic on a major street here.

That said, the e-bike riders are often wearing helmets as they plow through pedestrians, so maybe their recklessness only extends to the safety of others, and they'll be conscientious about not lighting a lithium battery fire between their own legs.
