The bike stand on the Stromer gives little cause for complaint. Every now and then you can read in a forum post that it broke at the mounting plate.
However, the automatically folding Pletscher stand on the ST2 2014 was unstable and was later replaced by a Hebie.
Again and again, alternatives were discussed that would make the Stromer (even) more stable. To anticipate - no serious ones were found.
Stromer offers two different Hebie models that differ in length. This is due to the change from 26″ to 27.5″ tires.

The newer model from Stromer costs €75 and fits all Stromer models with 27.5″ tires: ST7 | ST5 2023 Pinion | ST5 ABS | ST5 2018 | ST3 Pinion | ST3 | ST2 2023 Pinion | ST2 Belt | ST1 LCI | ST1 2019
Alternative
The Stromer bike stand is (almost) the model Bicycle stand Mittelbau 632 | eLEX from Hebie. The mount of the original Hebie does not have a Stromer thread. This must be adapted.
- Drill out the M10 threaded hole so that the M10 fixing screw can be inserted through without any problems.
- As the screw head is too wide for reverse fastening, the contact surface and recess on the stand must be reworked, e.g. with a Dremel. This allows the screw, including lock washer and washer, to be inserted cleanly and screwed onto the mounting plate on the Stromer.
- The length of the fastening screw may need to be adjusted for installation. [Source]

The photo section is from an ST2 (26″). The newer stand for the 27.5″ models also fits in terms of the mount, but could be a little too long. The shortening (~1 cm) can be done by removing the PVC foot (goes tight), shortening the tube and remounting the foot. Conversely, the 26" model also fits on the 27.5" models, the Stromer simply has a little more inclination and tends to tip earlier when heavily loaded.
