Could You please note the full name of the 3.6 software here? I can go back to Chili and ask her to provide this file to me, the I can post it here! Thanks mate!
You think the frame may be damaged? I think the main reason for weight reduction is the closed downtube without battery cutout. I would take the risk and try it 😊
The challenge on the range extender is how to connect to the system. One option is to plug it into the charging port (like Orbea and others) with reduced amps flowing into the main battery. Not a good option imho, because if You drain the main battery qicker then recharging will be possible...
Well, the Bafang 410Wh battery weight is out of 2023 Workbook. The 720Wh battery weight ist quoted from the frame manufacturer selling this battery. In my world this is more then an assumption 😊

It will give You a flater steering and seat angle by appr. 1.5 Degree compared to original specs. More downhill / enduro geo, but very good to ride imho.
I saw this somewhere already. Remember the extremely low BB @ 327mm. Looks like the Kabon

I don’t need stealth look / hide it’s an ebike. I think the CEF50 has a verny nice and still slim silhouette. Noise is important for me, and I‘m so curious to see how the M820 will perform and sound. And the best: I have You guinea pigs 😂 to test it! Cross fingers that it it will be a great...
