Ok, I have my answer from Bosch technical: Bosch doesn't fix motors that are not covered by warrantly (2 years) and they charge me a full motor exchange ($700).

The motor has been sent for the second time to Bosch because they didn't found any issue the first time. That's why I done a video for them. Now I have to wait for another 3 weeks (I live in France at around 400km (250miles) from Deutschland ... imagine if you need to send your motor from USA !!! )

The promised video about my Bosch Active Line (2 years old, 6000 miles) slips as hell with crank load https://youtu.be/EBW3s5iZSoE

When the wheel looks not true, last time it was after 7000km (4300 miles)

Yes it is overkill, but it was easier for me to clamp this heatsink. Also this is for a 7000W setup.

I tried some of these SSR and they burn if the inrush current is to high. That mean you still have to deal with a pre-charge resistor before switching the main power with the SSR. As I wanted to use only one switch to power the bike I had to connect like this: The main switch connect the...

You can do it, have a look:

Sorry, yes you can add a tiny copper link to bypass this shunt. Then try if power is increasing. After the test add some solder around the copper. Be carefull to check the fets temp, they may burn while climbing.
