Should work and it is working.
I changed a while ago my cassette and did a mistake, which leads to a blocked freehub. I didn't even realize it till I came back and turned the wheel by hand.
I'm riding Vitoria. Now in Winter the Mota and in Sommer rear Martello Front Mazza, but the normal one.
I see no reason for eBike tyres (only more money for the vendor).
Why should everything eBike ready? It is more or less a normal bike.
As said, you need to push the button on the battery while battery is inside the bike.
System will start and charge the power button.
Alternative is the USB Interface PCE02
The battery inside power switch is down.
You need to be creative and push the button on the battery inside the bike.
I know from people, they wrapped a zip tie around to do so.
It is discussed many time here and in other forums. The new switches, buttons, etc. are not wokring with the "old" EP8 Motor system due to the new CAN bus.
I would love, if it would work, I want the new display and power button.
