SEFIS Basic bike lock with alarm

SEFIS Basic – highly durable lock with alarm for bicycles, motorcycles and scooters

Every cyclist faces the challenge of keeping their bike safe. The SEFIS Basic lock with alarm protects your bike from theft and damage, surprising you with its solid, all-steel construction. Aside from its robust, tamper-resistant design, the SEFIS Basic also features an integrated alarm triggered by a motion and shock sensor – the moment anyone tampers with your bike, the 110dB alarm sounds immediately. With its 6mm pin, it is perfect for any bicycle equipped with disc brakes, as well as motorcycles and scooters.

Siren alerts you to unauthorised tampering

Applying the SEFIS Basic lock is incredibly easy – just fit it directly onto the brake disc and lock it by pressing the locking mechanism, without needing a key. After 5 seconds, a confirmation beep sounds to let you know the system is active. In the event of unauthorised tampering, the alarm first gives a triple-beep warning. If the bike remains in motion, the siren sounds at full volume for 10 seconds. If the tampering continues, the alarm triggers repeatedly. If the movement stops and does not recur within 30 seconds, the alarm resets to its original active state.
