Those "bikes" look like they do have pedals and a self-propulsion mechanism, just hidden beneath all the bodywork designed for it to look more scooter like.
But I agree, the line between bike/scooter is more blurred than before.
I'm a bit skeptical about some of these claims about the greeness of ebikes and scooters tbh. Here in London we have fleets of e-bike/scooter schemes than can't be profitable. The get vandalised and stolen, and then the bikes can get left anyway on the sidewalk which sorta pisses everyone off. They pay some poor sod minimum wages to drive around the city overnight and pick them all up and return them to their parking stations. It's not a sustainable business model.
There's a huge difference between (the greenness of) owning and using your own e-bike/scooter and those rental schemes. Don't think you should conflate the two. Those schemes have tons of flaws, but that's not really what this is about.
Would either/both of you care to elaborate on your complaints about these programs? To my mind, a car trip replaced with a micro-mobility trip is just as good whether the user owns or rents the device in question.
These rental schemes get a hell of a lot of people's foot in the door who might not be willing to make the upfront investment of buying a scooter or e-bike themselves or don't have the storage space. It makes it easier for tourists to decide they don't need to rent a car. They provide peace of mind for people who are worried that their bike would get stolen if they bought their own. There are a lot of benefits to these things.
I've heard lots of anecdotes of people who own their own bikes making regular use of bikeshare bikes just to have flexibility (bike downhill, take transit back up; or bike to the bar, take transit after they've been drinking). I have lots of friends who went to a school in downtown LA without cars, and scooter rentals seemed to be really genuinely useful for them due to the lack of better transit service in LA.
I just don't see the reason for the hate. Yes, it costs money to replace and repair stolen/damaged bikes and scooters, yes maintaining the system requires employing people to drive around and move bikes between stations or retrieve abandoned scooters... But so what? It costs money to pave roads, it costs money to provide free or subsidized public parking, it costs money to repair sidewalks, it costs money to run a transit system. It's a piece of the overall puzzle of solving our transportation woes, which gets more people to take the lower-carbon, and less space-intensive option rather than driving. That warrants some public subsidy.
The "can't be profitable" line seems just as nonsensical here as when applied to public transit, and I don't understand where the purported "difference in greenness" is supposedly coming from. Yes, there's more wear and tear on a shared rental bike/scooter, so they need to be replaced more often... because it gets used a lot! That's a good thing!
And again, the nuisance of some young people *gasp* having fun riding around town on e-scooters, or some jerks leaving some scooters laying around carelessly, is a fraction of a percentage of the harms caused by cars.
