You can just Google Amyet S8 front motor problems. There are some threads on Reddit. I did come across one thing, someone also had trouble plugging in the front motor and he said he couldn't do it until he cut off all of the zipties in that area.You said some people are experiencing issues w the front motor out of the box ? Who is ?
Another thing you could check, if it is still an issue, is unplugging your brake cut offs. I don't know how they arrange them with dual motors but if one goes to the front and it is sticking in the off position then the motor won't run.I just did and I didn't see a lot of bikes w this issue. I'll do my best to get those wires 100% seated and then go from there.
Yay! Spring will make everything better still!I warmed up the wire connectors with a hair dryer today. After some attempts, I was able to finally push the ends fully together. Everything is good now !!
