Bike cable locks are lightweight, flexible and easy to carry. Their generous reach makes them useful for awkward locking points, securing accessories and protecting a second wheel, while compact designs are convenient for short, lower-risk stops.
Why Choose a Bike Cable Lock?
A cable can pass around larger objects and multiple parts of a bike more easily than many rigid locks. This makes cable locks practical for riders prioritising low weight, simple storage and versatility. Security varies considerably, however, and most lightweight cables provide less resistance than a substantial D-lock, chain or high-rated folding lock.
What to Look for in a Cable Lock
- Intended use: Decide whether the cable will be your main lock for a brief, low-risk stop or additional protection alongside a stronger primary lock.
- Security rating: Check the exact model's Sold Secure rating where one is provided rather than judging security by cable thickness alone.
- Length and diameter: Longer cables provide more reach, while greater diameter can add resistance but also increases weight and bulk.
- Locking mechanism: Choose between a key and combination according to convenience, while comparing the construction and rating of the complete lock.
An extension cable is designed to supplement a primary lock, often by securing a wheel or accessory, and may not share the main lock's security rating. For guidance on when a cable is appropriate, read our Bike Lock Buyer's Guide.
