Vector Disc Locks JawX 10 & JawX A10 Review

The scene could be straight out of a biker novel: seven gleaming Ducatis line up in front of the café like pearls on a chain. Six of them stand unprotected, while on one the Vector JawX lock in the disc and the handlebar lock prevent it from rolling away. In this moment, it becomes clear what a disc lock is really about – not ultimately fending off professional thieves, but buying time and making your own property less attractive. Because if a potential thief has the choice between six freely accessible bikes and one with a visible security device, his attention will likely turn to the easier targets.

This is exactly what Vector developed the JawX series for – in our test, the mechanical version Vector JawX 10 and the Vector JawX A10 with alarm.

A disc lock is inserted through an opening in the brake disc of a parked bike and blocks its rotation. This means the bike can no longer simply be pushed or rolled away. Among the biggest advantages of this type of security are the compact design, low weight and quick handling. A disc lock fits even in a jacket pocket and is fitted within seconds.

High-quality models feature hardened locking pins as well as protective mechanisms against drilling, picking or forceful leverage attempts. This doesn't make theft impossible, but it significantly increases the effort and time required. Some models, including the Vector JawX A10, also supplement the mechanical protection with an electronic alarm. This reacts to vibrations and produces a warning tone of up to 120 dB, intended to deter potential thieves and draw the attention of bystanders.

However, security experts warn of the limits: cheap locks can be broken open with simple tools or bypassed by removing the brake disc. It is therefore advisable to choose a high-quality lock and – if the bike is left unattended for a longer period – combine it with a chain and a solid anchor point. For added security, many manufacturers recommend a brightly colored reminder cable that hangs on the handlebar, serving as a reminder to remove the lock before setting off. Vector includes such a cable as standard.

The JawX series will be launched across Europe in summer 2026 and comprises five models. In our real-world test, we focus on the two 10 mm variants: the JawX 10 (mechanical) and the JawX A10 (alarm). According to the manufacturer, all models are made from 304 stainless steel, waterproof and weatherproof, and protected against rust, impacts, drilling, picking and cutting.

Each comes with three keys and a spiral-shaped reminder cable. A double locking pin with a 10 mm diameter secures the shackle at both ends – a design considered particularly resistant to sawing and leverage attacks.

Vector JawX 10 The JawX 10 is the purist model: a 10-mm pin, no electronics, but 100% mechanical protection for 59 euros. It weighs 564 g and impresses with its clean design language. The brushed stainless steel surface looks classy, and the deeply engraved Vector logo along with the removable "shark mouth" sticker give the lock character. The three included keys are labeled "Vector" on the head, making them easy to identify even years later.

Vector JawX A10 For 79 euros, the JawX A10 offers the same mechanical base but adds an alarm function. Behind a screwed-on stainless steel cover sit six LR44 batteries that trigger a 120-dB alarm. The lock weighs 647 g. The electronics are activated via a small pull tab in the battery compartment and are armed instantly as soon as the pin is locked. The alarm horn is louder than some bike exhausts – a shrill siren that's more likely to cause annoyance in residential areas. All other technical features match the JawX 10: stainless steel housing, double locking, drill and pick protection, as well as the included reminder cable.

Both locks come in glossy cardboard packaging. Inside you'll find the lock, three keys, the spiral-shaped reminder cable, and, in the case of the A10, an extra-long Allen key for opening the battery compartment.

Right from unboxing, the stainless steel housing gives a high-quality impression: no powder coating that could chip after a crash, but bare steel that lets scratches age with dignity. The stuck-on "shark mouth" looks a bit clunky in photos but serves its purpose as an eye-catcher and can be removed without leaving residue. The engraving of the Vector logo impresses with depth and precision.

The purely mechanical JawX 10 is ready to use immediately: insert the key, push the 10-mm pin through the brake disc and press it shut, done. The locking mechanism feels precise; even in the dark, the key finds its way, with nothing jamming or binding. Clear feedback confirms that the pin is locked. Then attach the neon-colored reminder cable to the handlebar – and you can head off for an espresso with peace of mind. The double locking feature is practical: it secures the pin at both ends, making it much harder to saw through. In everyday use, we found the weight pleasant: at around half a kilo, the lock fits into any jacket pocket without being cumbersome.

The JawX A10 alarm version requires a small step during initial setup. Using the included Allen key, the cover is opened and the transport safety tab is removed, or the batteries are inserted. After that, the system is ready to use.

How it works:

1. The JawX A10 is pushed through the brake disc and locked with the key. A short beep sounds when locking – BEEP. The system is now armed. Any vibration first triggers a warning triple beep, and with further movement a bone-rattling 120 dB siren follows.
2. When unlocking, the lock remains silent at first. Only when you subsequently lock it again away from the brake disc to remove the key does a double beep sound – BEEP BEEP. This signal confirms that the alarm is deactivated. The lock can now be stowed away quietly, battery-friendly and without false alarms.
3. This principle repeats with every use: lock the bike – BEEP – alarm active. Remove the lock and lock it for storage – BEEP BEEP – alarm deactivated.

Note: The idea behind this is as simple as it is clever. Still, you should stay alert: if the alarm is accidentally activated inside a packed backpack, every movement becomes an involuntary test of nerves.

Feel, locking mechanism and build quality match the JawX 10. Only the integrated electronics make the JawX A10 somewhat bulkier and noticeably heavier.

A high-quality disc lock can't always prevent theft, but it significantly raises the hurdle. Its purpose is to cost time, increase the effort for potential thieves, and make your own bike a less attractive target compared to unsecured machines.

Which of the two JawX models is the better choice depends mainly on your personal usage profile. The JawX 10 convinces as an uncomplicated everyday companion. It's lighter, more compact, cheaper and always ready to use. Anyone securing their bike in front of a café, at the office, or during a quick shopping stop gets exactly what a good disc lock should deliver: maximum simplicity combined with high everyday usability.

The JawX A10, on the other hand, is aimed at riders who regularly park their bike in places where they can actually hear an alarm. In the home garage, outside the bedroom window, in a hotel garage, or next to the tent while bikepacking, the 120-dB siren can offer real added value. The acoustic shock effect is enormous and is likely to stop many theft attempts right from the start.
