Hi, it is possible to change the engine. For example when I now purchase the 4 kW Model, will it be possible, when the 7kW Model is released to change the Engine from 4kW to 7kW (by Hardware).
Aand I´ve got another question what is the range with 3 batteries when I drive 50 km/h or much more (e.g. 80-90km/h)
I look forward to your Reply.
