Indian scooter maker Hero, is offering an electric scooter with dual batteries. As shown in a video review, here are two compartments under the seat to hold two batteries. The scooter can be operated with both batteries installed for maximum range, or one, while the other is removed for charging.

As the battery is a large investment, it would also be worth providing the option of using it to supply limited household power during a blackout.
ps: There are swap and go designs for interchangeable scooter batteries, such as Gogoro Network, but these all suffer from being proprietary systems.
