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
