Except that there are no 48V engines...just 48V motors.

(AFAIK: An engine is a motor which converts thermal energy to mechanical energy. A motor is a machine that converts energy to motion. Thus, all engines can be motors, but not all motors are engines. I could be mistaken, of course.)

I don't know anything about the specs of similar 48V scooters to compare, though.

Thank you for clarifying. In my mother thongue there is no distinction.
Anyway,
A small correction on what I wrote above, in the translation of the website, the company merely says that 96V engines are more efficient. I got confused because their range measurements are in km instead of miles.
Their range is about as good as the modern bikes, although I believe their claim about 96V being more efficient.

96V means you could charge the battery with a minimum on charger equipment (just an AC-DC converter from 110VAC to 96V DC). It would making a charger for such batteries extremely cheap and lightweight. (I've read an article of a guy just using a graetz bridge (diode bridge), and capacitor, to fast charge his batteries on 110V. That's less than $15-25 on material.
And also interesting to be able to plug in a power cord straight into the bike, without the need for a separate charger, or worrying about Ah rating of extension batteries. Technically the net has enough power to charge 110V upto 15A, and some go even upto 20 or 25A.

Normally a battery 96V, 10Ah, is about as powerful as a 48V, 20Ah.

On their specific equipment, it may well be. But actual efficiency would depend on many factors, including the speed at which it is used and the design of the vehicle.

There are several threads on "bad boy" chargers here on ES, some of which were successful, and some of which weren't finished or tried, or failed.

Normally a battery 96V, 10Ah, is about as powerful as a 48V, 20Ah.

Not "as powerful" but rather "has the same capacity as". Whether it is as powerful or not depends on the cell types and interconnects, as well as the BMS if any.

If only it was that clear cut....
