I needed a lock that could secure two bikes and attach compactly to the frame. This one is very convenient and lightweight — it even fits into a rear jersey pocket. The frame mount is also quite practical and easy to use. Unfortunately, I didn’t check the security rating before buying. More secure locks are at least twice as heavy, so this one is best suited for short stops — like grabbing something from a store or a quick coffee break. That’s exactly how I use it

The lock meets my expectations: good size, attaches to the bottle holder, or can be mounted without screws using Velcro - great. The lock itself is easy to operate. I realize that it's not the most safe place to set off, but I only wanted it for short stops to shop or stop off while on tour.

Das Schloss entspricht meinen Erwartungen: gute Größe, Befestigung am Flaschenhalter ,oder ohne Schrauben per Klettverschluss montierbar-top. Das Schloss selbst lässt sich leichtgängig bedienen. Dass es nicht das aufbruchsicherste ist,ist mir klar, wollte es aber auch nur für kurze Zwischenstopps zum Einkaufen oder Einkehren auf Tour.

Good lock, surprisingly light.

Gutes Schloss, erstaunlich leicht.

The thing really weighs just under 600 grams including the holder. That's one word. It's still quite bulky, but value for money is good.

Das Ding wiegt wirklich knapp unter 600 Gramm inklusive Halterung. Das it ein Wort. Es ist immer noch recht klobig, aber Preis-Leistung ist gut.

Possible to install anywhere on the bike frame
