SPGOOD Heavy Duty Bicycle Lock 830mm Chain 5-Digit Resettable Code
Product description
This heavy duty lock provides durable protection for bicycles, scooters, doors and gates. The 830 mm chain offers ample length for securing a bike to a fixed object and the 7 mm hardened steel links help resist cutting attempts. The 5 digit resettable combination is easy to set and change, making it a practical option for daily use in urban settings 😌.
This is a versatile security solution designed for riders and homeowners who want a straightforward way to lock up assets during short stops or longer away-from-home periods. The lock uses a robust head construction and reinforced nylon materials to withstand typical handling and weather exposure, while keeping the mechanism relatively simple to operate. With a broad colour choice, you can select a shade that matches your bike or home style.

Key Points


SPGOOD Bike Locks Heavy Duty/Bicycle Chain/Cycling Lock (14 Colors) 5-Digits Codes Resettable 100,000 Codes for Bike Cycle, Moto, Door, Gate Fence 830mm Length(Red) offers a practical balance of length and strength for everyday security. The chain is stored in a compact form when not in use, which helps with portability on commutes or weekend rides. The 5 digit code can be customised following the included instructions, and the factory setting is 00000 to simplify initial setup. A longer chain gives you more flexibility when looping the lock around frames, posts or railings, and the bright red finish helps with visibility in low light. The model is available in fourteen colours, so you can pick a tone that suits your gear or home exterior. 🧷

In practice the combination lock reduces the need for keys and offers straightforward operation, even when you are wearing gloves. The reinforced head and nylon components are selected to improve durability while keeping the overall weight manageable for carrying in a backpack or cycling bag. It is worth noting that the security level depends on the environment and the ease of access to the chain, so pairing with a secondary lock or selecting well lit, busy locations can improve protection. The design is aimed at delivering reliable everyday performance without overcomplicating the locking process.

Usage Recommendations

For best results, secure the frame and a fixed object as close as possible, avoiding slack in the chain. Avoid leaving the lock unattended in direct exposure to harsh weather for extended periods; when not in use store it in a dry place to extend its life. If you are locking bicycles at busy urban locations, consider a secondary lock for the wheels or seat to deter opportunistic theft. The combination should be checked and updated periodically to maintain security.
Practical Notes
The 830 mm length provides flexibility for locking larger frames or pairing the lock with another security device if needed. The 7 mm hardened steel offers solid resistance for most casual to mid-range theft attempts. If you require higher security levels for high-risk environments, additional security measures may be appropriate.
