Couldn't load pickup availability
The JOYOR S8-Z Anti-Theft Alarm XT90 is a factory-designed security alarm specifically for the JOYOR S8Z electric scooter. It mounts near the rear wheel or controller housing and integrates with the scooter’s wiring harness via the XT90 connector to deliver audible alerts when unauthorized movement or tampering is detected. This alarm enhances theft deterrence by emitting a loud, attention-grabbing siren when triggered.
Replace this alarm if it fails to activate, produces weak or no sound, or loses synchronization with the scooter’s power system — common signs of electrical wear or connector corrosion. It is intended for use as a direct replacement part and is not compatible with aftermarket controllers or non-S8Z models.
This is a genuine JOYOR replacement part engineered for precise fit and function on the S8Z model, ensuring seamless integration with original wiring and security protocols.
