USAGE AND MAINTENANCE

Before leaving


  1. Position — Align the axis (6 mm) with a brake disc hole.

  2. LockPress to activate: a beep confirms activation.

  3. Test — Lightly touch the motorcycle: pre-alert (short beeps).

    If the vibration continues → alarm 110 dB ~10 s.


  4. Unlock — Insert the key, turn: the alarm stops immediately.

Compatibility


  • Motorcycles, bikes, disc scooters with holes ≥ 6 mm and accessible.

  • Not suitable for wheels without a drilled disc.

Good practices


  • Always mount the block on the disc (not on the spokes/tire).

  • Orient the opening away from the ground to limit splashes/water.

  • For prolonged parking: combine with frame/chain lock to maximize deterrence.

Maintenance (simple and quick)

Battery


  • Symptoms of low battery: volume decreasing / abnormal beeps → replace.

  • Battery access: use the provided Allen key, open the hatch, change the button batteries (type LR44/AG13 depending on your version), close.

  • Tip: keep a spare set of batteries on hand.

Water resistance & cleaning


  • Resists rain (outdoor use). Avoid prolonged immersion.

  • Clean with a soft cloth slightly damp. No high-pressure jet on the speaker.

  • Do not apply any lubricant inside the alarm module (risk of false contacts). If necessary, a micro-drop of dry lubricant on the key only.

Storage


  • When not in use: store it in a dry place, in a pouch or under the seat.

  • If inactive for a long time: remove the battery to prevent discharge.

Periodic check (30 s/week)


  • Check the trigger (tap test), the tightness of the lock, the condition of the cable return and the integrity of the disc at the anchor point.

Safety


  • Never ride with the lock in place — the anti-forget cable is there for that.

  • Place it in a visible manner: deterrence starts before the break-in.

Frequently Asked Questions

Frequently Asked Questions

If you do not find the answer to your question here, please contact us.

Is it compatible with my bike?

Yes if your bike has standard disc brakes. The block locks onto the opening of the disc (shaft ≈7 mm).

Also suitable for e-bikes, gravel/urban with disc, and most disc scooters.

How does the alarm work?

After one-click locking, a sensor detects shocks/vibrations: at the slightest touch, the 110 dB alarm sounds immediately and scares away.

To disarm: unlock with the key and remove the disk lock.

Waterproof? Usable in the rain?

Yes. The body of the disk lock is designed for urban weather conditions (rain, wet sidewalks). Dry quickly after heavy rain to preserve the mechanics.

And what if I forget the disk lock before leaving?

Never ride with the disk lock in place: risk of damaging the brake/fork.

Tip: use a bright-colored reminder cable to the handlebars so you don't forget it.

Is it enough on its own?

No lock is “unbreakable”. The disk lock + alarm provides an immediate deterrent ideal for short stops (restaurant, shopping).

For long-term parking, add a U/chain to a fixed point if possible.

6. Piles & autonomy

Power supply by button batteries (type LR44) that are replaceable. Autonomy of several weeks to a few months depending on the triggers.

Simple replacement: open the compartment, change, close.

7. False alarms / sound volume

The module is calibrated to ignore micro-vibrations and react to real keys. Secure the disk lock firmly and avoid it hitting a beam. The 110 dB are brief but very dissuading.

I lost a key... what to do?

Two keys are provided. Keep them separate. In case of loss, contact us (support@ozalo.fr) for cylinder/key replacement options.
