What to Compare Before Buying
- Reach: Check that 1 m is enough to pass around the bicycle and the fixed object you plan to use.
- Link thickness and lock type: Compare the 6 mm links and combination mechanism with other locks you are considering. The listing does not provide a security rating, so do not treat the chain description as a guarantee against theft.
- Selected variant: The listing describes other length and color options. Confirm that the selected configuration is the black 1 m version if that is the one you need.
Setup and Correct Use
The listed default combination is 00000. The supplied reset instructions say to set the dials to the current unlocking code, rotate the reset dial 90 degrees, and set the new code. Change the default before relying on the lock, and keep the chosen combination somewhere secure. The polypropylene sleeve is intended to help protect the frame and other contacted surfaces from scratches.
Before You Decide
Check the chain’s reach at your intended locking point, confirm the 1 m black variant, and choose a combination you can recall. A chain lock can help secure an item, but it cannot guarantee theft prevention.
