Buying Guide: 120cm Bike Locks
📋 Table of Contents
1What security rating should I look for in a 120cm bike lock?
Opt for a lock with a minimum security rating of 5 or higher from the Sold Secure or British Standard BS EN 16221. Higher ratings indicate better resistance to cutting, drilling, and picking, which is crucial for urban areas with high bike theft rates.
2What materials are best for a 120cm bike lock?
Stainless steel or hardened steel shrouds offer the best durability and resistance to tampering. Avoid cheaper zinc or low-grade steel, which can bend or break under pressure. A solid shackle made from hardened steel is also essential for added security.
3Is a U-lock or a D-lock better for a 120cm bike lock?
A U-lock (also called a 'U-shaped' lock) provides better security for a 120cm length due to its compact, rigid design, which is harder to cut. A D-lock, while strong, is bulkier and less convenient for securing bikes in tight spaces or on public transport.
4How thick should the shackle be for a 120cm bike lock?
Look for a shackle thickness of at least 10mm, as thinner shackles are more vulnerable to cutting tools. Thicker shackles, typically 12mm or more, offer greater resistance and are recommended for high-theft areas or long-term outdoor use.
5What accessories should I consider with a 120cm bike lock?
A lock with a built-in cable or chain extension can help secure multiple bikes or lock to a rack. A keyless entry system, like a combination lock or Bluetooth-enabled model, adds convenience. A lock with a dust cover or protective sleeve can also extend its lifespan in harsh weather conditions.
