This scooter is to expensive
Not inside everything what looks like an E-Max S is the same technic, even when the product is offered to the same price of nearly 2000.-EUR.
Here an outside similar model with a 1500 Watt engine. The E-Max S has to compare 2200 Watt and 3850 Watt with power button.
The vendor thought at such a weak engine are half the batteries enough.
A look over the rear wheel shows, behind the battery box is no further place for batteries. I assume there is much less battery capacity inside.
