"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:

Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.

Regen is a fairly common feature in ebikes. It doesn't work while you ride, other than as a brake going down hills, but as most are hub drive if you lift the rear wheel off the ground you could use the bike as a generator and charge the battery by pedalling.
However, it would in no way be energy (food) efficient compared to just using a bicycle due to the losses, but if you needed it for emergencies or for powering something else, it could be used.
It's not a common feature.
It doesn't make as much sense to do on an bike, mainly because regenerative breaking requires more expensive electronics and stresses the battery more.
My family has 7 ebikes, all different models and none has regen.
It also requires special frame dropouts consideration because of the back-and-forth torque. Typically a strong torque arm.
Regen is only really a thing with direct-drive hubs and not even with all of them. Yes you can weld the clutch of a geared hub, but this isn't done in production. Some DIY shops like Grin do it on some motors but that's not a widespread practice. And there's definitely no regen on mid drives. To be clear, I'd absolutely use regen if I had a direct-drive hub, because the controller I use supports it, but yeah, it definitely isn't common.
Grin is co-developing a mid drive regen. It has a neat design.

Not a mid-drive but a geared hub. And yeah, it's a pretty cool design. I'm just worried about cost and water/salt ingress.
Whoops, you're right. I misremembered that for sure.
Totally agreed with the cost. Grin motors are pretty inexpensive, but not many companies have a complete system. Who knows what a licensing agreement would run.
