I think there was a Renault that worked like this. I think the main issue is that you need a decently sized battery that can supply enough power or else the ICE needs to start every time you hit the gas pedal like was the case with the older Prius models and then you might as well connect it to the wheels and you can have a smaller electric motor.

But batteries keep improving and you can pull more power per kWh now. Maybe with solid state batteries this power train could become the more affordable option.

There was a scooter sharing company that drove around, swapping the batteries. It went out of business and now there are only the Bird style scooters.

If there were battery swapping stations, I’d definitely by me a bike.
