FAQ

Can I set my own combination?

Yes — it's a resettable 5-dial combination (default code 00000), giving roughly 100,000 possible combinations.

Is this strong enough to be my only bike lock?

No — cable locks like this one are the weakest common lock type and can be cut with basic tools in seconds. Use it as a second lock for a wheel alongside a real U-lock or chain lock, not as your only line of defense in public.
