VanMoof error 54: Internal SIM card not detected

VanMoof S3 / X3 (also S5 / A5 where applicable)Fix at homeSafe to keep riding

The cartridge cannot find the built-in SIM that the bike uses for GSM location tracking and remote features. Riding and Bluetooth unlocking are unaffected. The code is mostly relevant for theft tracking and for owners whose bikes lost VanMoof connectivity after the 2023 bankruptcy and relaunch.

Likely causes

Temporary modem glitch after a firmware update or hard reset
SIM contact issue inside the cartridge after vibration or a knock
Cartridge with a dead or deactivated SIM (some older bikes were never re-provisioned after the relaunch)
Water in the cartridge
Modem firmware not booted properly (see error 58)

How to fix VanMoof error 54

Hard reset: power button 10 to 15 seconds, wait a minute, power on and let the bike sit outdoors for a few minutes with a clear sky
Check the app: if location and remote features still work, ignore the code and watch whether it returns
Install any pending firmware update
If you have not used the app for a long time, log out and back in so the bike can re-register with the current VanMoof backend
If the code persists and you rely on GSM tracking, an independent VanMoof-capable shop can reseat or test the SIM in the cartridge; be aware that connectivity depends on the relaunched VanMoof keeping the service running

Go to a dealer if: Go to a shop only if GSM tracking matters to you and the code stays after a reset and firmware update; the bike rides fine without it.
Warranty: Warranty from the original VanMoof B.V. died with the 2023 bankruptcy; the relaunched VanMoof (LAVOIE/McLaren Applied) only covers bikes sold by them after the relaunch, so most S3/X3 owners pay for repairs.
Typical cost: Usually nothing; a cartridge inspection is about EUR 50-100, and a cartridge swap EUR 300-500 if the modem or SIM is dead.

Still stuck? Take a photo of the display and show it to a local e-bike workshop. Bring the bike's system name (e.g. Bosch Performance Line CX) and the exact code; that saves diagnostic time and money.

Frequently asked

Does error 54 stop my VanMoof?

No. It only affects GSM tracking and remote features. You can ride and unlock via Bluetooth as usual.

Does VanMoof tracking still work after the bankruptcy?

The relaunched VanMoof kept the app and servers running, but coverage and support vary by country. Do not rely on it as your only theft protection.

Can I replace the SIM myself?

It is soldered or seated deep in the cartridge. Not a home job, and a different SIM will not work without VanMoof's provisioning.
