Sportneer Ultra‑Thick Chain Lock

The Sportneer lock uses a 120 cm long, 8 mm diameter manganese steel chain, delivering high tensile strength for enhanced resistance to cutting attempts. Its compact heaviness offers portable security suitable for bikes, scooters and light motorcycles. The design features a waterproof and dirt-resistant cap over the lock head to minimise rust and jam from wet weather, while the 360° rotatable lock head streamlines clipping and alignment. A wear-resistant protective cover safeguards both the lock and bike frame from scratches during use. Regular application of anti-rust solutions is advised for longevity.
SPGOOD 3‑Key 90 cm Lock

This SPGOOD model offers a 90 cm length with a 6 mm hardened steel chain, and an included three-key set for convenience. A hard-wearing nylon cover protects the chain from UV exposure and prevents scratches on the bike frame. The waterproof design at the lock opening helps deter rust by keeping rain and snow away from the cylinder, ensuring smoother operation in UK weather. The relatively light footprint makes it suitable for everyday cycling and quick locker visits at work or leisure sites.
GRIFEMA GA1201-12 High Security Lock

The GRIFEMA GA1201-12 combines a 7 mm diameter chain with a zinc alloy lock cylinder for resistance to drilling and tech-based unlocking. The lock ships with two keys, mitigating lockout risk should one key be misplaced. Its waterproof and dustproof cover protects the cylinder from moisture and debris, extending service life and maintaining low friction operation. A compact, heavy-duty option suitable for bikes, motorcycles, and perimeter protections on gates and doors.
SPGOOD 1200 mm Coil Lock With Mount

This SPGOOD model features a 1200 mm long, 12 mm thick steel cable and includes a mounting bracket for quick attachment to a bicycle frame. The reinforced zinc alloy lock cylinder and durable ABS housing offer strong resistance to cutting and prying attempts, while the spiral shape allows convenient wrapping and storage. The included mounting accessory helps cyclists secure the lock when not in use, a practical accessory for daily commuting and travel on crowded UK routes.
SPGOOD 14-Color 830 mm Lock

This 830 mm length lock from SPGOOD uses a nylon-nylon blend outer coat with a 5-digit resettable combination. The large length protects bicycles, scooters and other assets by enabling secure anchoring to fixed structures. The combination mechanism is factory-set to 00000 with a straightforward reset process, offering flexibility for personal codes. The robust construction provides a balance of portability and deterrence against opportunistic theft for city and suburban cycling in the UK.
Ainiv 65 cm Resettable Lock

The Ainiv 65 cm lock uses a high-quality zinc alloy core with a PVC-wrapped steel cable for rust resistance. It provides a four-digit resettable combination, enabling up to 10,000 unique codes. The compact design makes it ideal for lightweight packing on commutes or park-and-ride stops, and its anti-corrosion construction supports reliable use in damp UK climates. The lock is suited for bikes, motorbikes, scooters and gates that require a portable, easy-to-carry security solution.
Buying Guide
- Security level: Choose thickness and material balance that suits your risk. Thicker chains and hardened steel offer more resistance to cutting tools.
- Lock type: Chains and cables trade off weight for flexibility. Mounting brackets and retractable designs aid portability for daily use.
- Weather resistance: Look for waterproof caps, dustproof covers and corrosion-resistant cores to cope with UK rain.
- Key vs. combination: Keys provide straightforward access, but spares add resilience. Combination locks avoid carrying keys but require code recall.
- Length considerations: Longer locks secure multiple points or larger bikes but add weight. Shorter options are lighter for quick stops.
- Mounting options: Brackets and clips help you attach the lock to your frame without hindering riding.
- Maintenance: Regular lubrication keeps the lock cylinder functioning smoothly and extends life in damp environments.
- Multiple-perspective choices: For urban use, a balance of portability and security is essential; for trail use, heavier chains may be justified.
