Introduction
The Giant SureLock Flex Combo 15 is a flexible, self-coiling cable lock with a resettable 4-digit combination—ideal for commuters and urban cyclists seeking a lightweight, quick-stop security solution. Weighing around 800 g and featuring a tough vinyl coating with a quick-release mounting bracket, it’s perfect for brief café breaks or short errands.
Design & Build Quality
Featuring a 15 mm heavy-duty flexible cable, this lock balances portability with deterrence—though it’s not designed to stop determined thieves. The vinyl cover protects your bike’s frame from scratches, while zinc end caps add impact resistance. The bright, 4-digit fluorescent combination dial offers up to 10,000 possible codes and eliminates the hassle of keys.
Performance & Features
As a “café-stop lock,” it excels at keeping “honest people honest,” per user feedback. The 180 cm length coils compactly, yet has enough reach to secure the frame, wheel, or even a stroller. Convenient quick-release mounting makes it easy to carry.
