The models ST5 2021 ABS | ST5 2018 | ST3 2022 Pinion | ST3 2018 | ST2 2020 Belt | ST1 2021 LCI | ST1 20197 use an 'All in one' Higo plug-in connection from the Type HG-F.M-L1019Awhich combines all connections to and from the motor. Shown here is the Higo Panel Mount L1019AM 03 DQ 300 on the left chain stay.

Older models
Stromer used various motors from different manufacturers in the course of model development. Accordingly, different connection configurations were also used.

Here is an ST1-V1 motor (400595_Wheel-Rear-M33-ASI-Silver_UltraMotor) with four connections.

The cables were usually connected to the electrical system under a sleeve beneath the left-hand chain stay. The connection on the far right is the programming plug for the controller in the motor.

On models such as the ST2/ST2S, a more complex connection cable was used, which could be decoupled from the motor. This was sometimes a source of error due to cable breaks.

A connection from Mutual was used here, one HT-F-M Mini C.
