Glad to see innovation in bicycle space. That said, when I was living in NYC, I was always afraid that someone on an e-bike would hit me when I'm trying to cross the road (esp. in the evenings or when the weather doesn't permit a lot of visibility). Some of these e-bikers also ride on the pedestrian platforms and it's dangerous (as of 2022, I don't think there was any enforcement to keep them out of the platforms).

It'd be interesting to see if/how e-bike laws would evolve if this trend gets bigger (ebikes are already big in big cities like NYC)
