I think electric stand up scooters have a strong future. They are extremely convenient in that they can easily be taken inside offices, in elevators, on public transport, etc which is something you couldn't easily do with bikes. They really boost the usefulness of public transport because you can now quickly get to the nearest stop even if its 1-2km away.
Unfortunately they are illegal by default in much of the world but this seems to be changing.
