Hi Redshifquasars, you can check the correct torque value for your ST5 by opening up the app on your phone ( linked to your bike) and going to the "profile" tab at the bottom right of the main screen. Scroll down to user manual page 31. All the correct torque values for your bike are listed there.If your bike still has the original TMM sensor the correct rear axle value is 25Nm.
If your bike is equipped with the newer version it is 40Nm. Last time I checked the user manual had not been updated.
In the service menu you should be able to see wether it is a P178 ( old ) or P211 ( new ).
The service menu can be accessed by 1- pulling and holding for 10 seconds the right brake then hitting the menu option on the bikes screen . The sensor menu becomes apparent and allows you to see which sensor is installed. Tighten with torque wrench according to instructions below.
Please proceed with caution .
I don't pretend to be an authorized Stromer bike mechanic. Worked for me. Hope this

Thank you @Petropoliskhan. i will check and see what version of the sensor i have and adjust accordingly. i currently have it torqued to 25nm and i am getting poor battery performance(post tire change). I am getting great performance but at the expense of mileage(again post tire change).

i do go in and run the sensor calibration before each ride.

update:
via service menu(thank you @@Petropoliskhan) it showed that the newer P211 is fitted to the bike. i removed bolt, greased, reinstalled and torqued to 40nm.

The power assist levels now feel normal on a 30 mile ride that I've been using to test batter performance and now have my normal percentage left over at the end of that ride(difference of about 15% with the bolt torqued originally at 25nm then updated to 40nm).

@redshiftquasars If you don't mind sharing, what's your mileage and battery range now?
All other variable aside. (Rider weight / rider style...etc)
My 2019 ST5 now has about ~6000 miles and range about ~60 miles. I pretty much mostly been using mode 2 since new.

my apologies @Insider for the late response. I've been recovering from a pretty bad tire fail.

*******i had a tubeless setup and had tires pumped to 43psi(im in the U.S.[p=pounds; s=per square; i=inch]). front tire had popped off the rim with a violent bang and lost control. i rolled under the a nearby car that was equipped with crash detection..... shoulder, head and leg trauma. bike is in good condition, minus tire situation********

from my app stats before any tire mods, i was able to get about 75 miles per charge on the blue battery[6'; 205lbs; low to med assist].

[i'm doing better and have stayed with safer MTB riding where falls on the dirt don't involve entanglement with cars on the road]

I'm in better shape now and have ordered tannus armour inserts with tubolito tubes {never going to use tubeless on the ST5 again}. pretty sure i can get like 80~90 miles out of a full charge. gonna try a Los Angeles to Santa Barbara ride soon on the ST5. will keep you posted
