SPGOOD 830mm Bike Chain Lock with 5-digit code 🔒

This heavy-duty bike chain lock offers straightforward security for bicycles, scooters and gates, combining a 7 mm chain with a resettable 5-digit code so you can secure belongings without keys. Its compact 830 mm length and 750 g weight make it practical to carry or wrap around a frame, while the resettable combination gives flexibility for everyday use.

Key Points

The lock uses a resettable 5-digit combination, with the factory setting at 00000 and the ability to set a personal code following the instructions. This removes the need to carry keys and allows up to 100,000 possible combinations for increased variety. 🔐

Construction mixes a hardened steel chain and a reinforced lock head aimed at resisting common tampering methods. The chain is covered in nylon to help protect paintwork on frames and to reduce noise when carrying the lock. 🚲

According to the manufacturer, the head material and nylon cover have been optimised in this version to improve durability. Consider that, as with many cable and lighter chain locks, very high-risk areas may require a heavier U-lock or thicker chain for maximum resistance.

Usage Recommendations

Wrap the chain through the frame and both wheels where possible to reduce theft risk, and loop it around an immovable object such as a bike rack or sturdy post. When setting your personal code, follow the included sequence carefully and test the new combination several times before leaving the bike unattended. For convenience, carry the lock in a saddlebag or loop it securely across a rack to avoid contact with braking surfaces.

If you need to protect multiple items such as a scooter and a gate, the 830 mm reach can be useful for linking several objects together. Bear in mind that while the nylon sleeve protects finishes, it can trap dirt over time so a periodic wipe down will help keep both the sleeve and the locking mechanism working smoothly.

Positive Aspects

The absence of keys simplifies daily use and removes the risk of losing a physical key. The variety of colours makes it easy to pick a visible or discreet option depending on preference. Overall the lock balances portability and deterrence, offering a practical option for lower to moderate risk environments.
