Stromer calls the automatic locking and unlocking of the bike 'Smartlock' (formerly Seamless Ride). The technology is based on Bluetooth technology.
Smartlock is available for the models ST1 with Omni B, ST1x with Omni C and ST2 /3 /5 /7 with Omni C.
After a revision of the function (SUI FW 4.2.1.8 from 21.10.2019) Smartlock works better, although not 100%.
Update: SUI FW 4.4.3.4 (7-02-2024)
Smartlock can now be used via the Riding Display in the Omni app.

Update: SUI FW Version 4.5.0.3 (05-03-2025)
Stromer writes in the release notes for the update:
The legacy SmartLock (locking and unlocking via standard Bluetooth) will be replaced by the new BLE version in conjunction with the Stromer OMNI app. Users who are currently still using the older version will receive a corresponding message. The Stromer OMNI app must be opened in the Omni via MENU > BLUETOOTH > OMNI APP be reconnected. SmartLock via Bluetooth BLE only works if the Stromer OMNI app is at least running in the background. The function is not active when the app is completely closed.
