Effective lock but read the instructions carefully first!
I rate ABUS kit functional with reasonable quality. This is a great product for it's intended purpose - ie preventing opportunistic theft by securing your bike for a few mins in low risk environments. It's lightweight and compact so can fit in a jersey pocket with no hassle. Fight the temptation to fiddle with it straight out of the box as you could get locked out of your own lock! The instructions aren't the clearest, but if you follow them carefully for first usage, you can set your own code and operate the lock quite easily.

good lock
good quality, easy to use. has all the functions that are important in these locks (its not just the locking and unlocking, but also the ability to lock the length of the chord - which this does, and a few other things)

Locked safe
Since we have friends who had their pushchairs stolen, I was adamant that we have a lock! Most of those on Amazon are shorter with 3-digit passcode lock. I was happy to find one longer. It is very compact and lightweight with straightforward instructions. The only bit I'm worried about is that it may feel too lightweight. I'm not sure how durable it would be, if someone actually tries to break it. Hence the 4 stars.

Useful security device
Works quite well, obviously not high security but works great as a deterrent. I purchased for securing skis when leaving unattended, for example when stopping at a busy mountain cafe or restaurant, or in an open ski room. Stops someone inadvertently taking the wrong skis by mistake, which occasionally does happen, a cheap and simple lightweight deterrent.

Great cafe lock.
Small enough to fit in your pocket! Feels like a quality product. Yeah it’s a thin cable but as far as locks go it’s better than no lock at all!. Cable length is about 1m so could go round two bikes. Perfect cafe lock and goes with me on every ride!

Brilliant
Great little lock & super for other uses as well. Bought this for a snowboarding holiday just for peace of mind over anything. Is it going to stop someone pinching your board or they have some hefty wire/bolt cutters... No. But does it act as a deterant for any sticky fingered individuals who might want a quick snatch of a decent board. Yes!! £20ish quid is nothing when you've spent several hundreds on your own board

Poor code setting instructions
Giving 3 stars based on lack of decent instructions for initial set up. Almost had it set to a random number due to poor instructions and set button releasing prematurely but thankfully worked it out. Better instructions please!! On a plus, seems nice & light for travelling with.

Good but not super secure.
Works ok, its made from plastic, so would not deter a determined thief. But its OK for securing the helmet to the motor bike, which is what I use it for occasionally

Ich habe mir das ABUS Combiflex Spezialschloss gekauft, um unterwegs eine schnelle und leichte Sicherungslösung für mein Fahrradhelm, meinen Rucksack oder mein Fahrrad in der Arbeit zu haben. Wichtig war mir vor allem ein Schloss, das handlich und unkompliziert ist, aber trotzdem zuverlässigen Schutz im Alltag bietet. Erster Eindruck / Verarbeitung: Das Schloss wirkt sofort hochwertig verarbeitet – wie man es von ABUS kennt. Das Gehäuse ist robust, die Zahlenräder lassen sich leichtgängig einstellen und rasten sauber ein. Das Kabel fährt federleicht ein und wieder aus, sodass es schnell einsatzbereit ist. Anwendung & Praxiserfahrung: Das Schloss ist sehr vielseitig nutzbar: • Zum kurzzeitigen Sichern von Taschen, Rucksäcken oder Helmen. • Perfekt für Reisen, da es klein genug ist, um in jede Tasche zu passen. • Auch beim Sport (z. B. Fitnessstudio oder Fußballtraining) praktisch, um Ausrüstung kurz anzuschließen. Natürlich ersetzt es kein massives Bügel- oder Kettenschloss – dafür ist es nicht gedacht. Aber für die schnelle Sicherung bietet es ein gutes Maß an Schutz und vor allem eine große Flexibilität. Vor- und Nachteile: ✅ Vorteile: • Sehr handlich und leicht, passt in jede Tasche bzw Trikottasche • Einfach zu bedienen (Zahlenkombination) • Hochwertige Verarbeitung, langlebig • Vielseitig einsetzbar (Helme, Taschen, Kinderwagen etc.) ❌ Nachteile: • Kein Ersatz für ein vollwertiges Fahrradschloss • Kabel könnte für manche Anwendungen etwas länger sein Fazit: Das ABUS Combiflex Spezialschloss ist die perfekte Lösung für alle, die unterwegs eine leichte und flexible Sicherung benötigen. Ob auf Reisen, beim Sport oder im Alltag – es bietet schnellen Schutz für Gepäck, Ausrüstung oder auch das Fahrrad und überzeugt durch Qualität und Handlichkeit. Für meine Zwecke absolut ideal.

Świetne kompaktowe zapięcie, które mogę mieć ze sobą na właściwie każdej przejażdżce. Oczywiście nie jest specjalnie mocne i pancerne ale do zostawienia roweru pod sklepem spokojnie się nadaje a mieści się w każdej kieszonce.
