Check on AmazonNo bike lock is unbreakable. A determined thief with a battery angle grinder defeats every consumer lock in under 90 seconds. The point of a good lock is to make your bike a worse target than the bike next to it - and to slow opportunistic theft (which is 80%+ of bike theft) to the point where the thief moves on.
Sold Secure (UK) and ART (Netherlands) are the only independent lock-rating bodies that actually attack locks with the tools thieves use. ABUS Security Levels and Kryptonite Security Ratings are manufacturer self-assessments - useful for comparing within a brand, not across brands.
Match the lock to where you park. Suburban quick stops? A solid U-lock is plenty. Urban overnight outdoors? You need at least a Sold Secure Gold lock plus a secondary chain or cable for the front wheel.
How we chose these locks
- Consider the time, place, and value of the bike when deciding what lock type and security level to carry.
- Check shackle or cable dimensions against the frame, wheel, and fixed object you intend to secure.
- Compare lock weight and carrying method with how far you ride and where you mount it.
- Review how the lock attaches to the bike and whether a holder is included.
- For a combination lock, consider whether preset codes and cable length suit your use.
- Treat manufacturer security ratings as product-specific information, not a guarantee against theft.
Picks are based on manufacturer specifications, applicable certifications, and published feedback. We do not claim hands-on testing unless it is explicitly described.
What to look for in locks in 2026
- Security rating (Sold Secure Gold/Silver/Bronze or ART 1-5 stars or Kryptonite 1-10 scale)
- Lock type vs use case (commute vs storage vs casual)
- Weight & portability for daily carry
- Key vs combination (key: better security, combination: no lost keys)
- Shackle/chain diameter and material (14mm+ for high-security)
- Anti-theft warranty and registration benefits
Sizing & fit
Match lock value to bike value (rule of thumb: spend ~10% of bike value). Inner U-lock dimensions need to clear frame + wheel + secure object. Standard U-lock: 4" x 9" fits most frames/single wheels. Compact: 3" x 6" for lightweight bikes/portability.

Locking to bad infrastructure
Sign posts unscrew. Wooden fences split. Chain-link fences cut. Always lock to a fixed steel rack, a steel railing, or a thick concrete-set bollard. If you can lift the object the lock is around, so can a thief.
Leaving the U-lock loose against the frame
A U-lock with empty space inside it can be levered open with a car jack. Fill the U with bike - frame, wheel, and rack - so a thief can't fit a lever inside.
Securing only the frame
Quick-release wheels walk off in 10 seconds. Use a primary U-lock through the frame + rear wheel + rack, plus a secondary cable through the front wheel. Or run thru-axles with security skewers.
Trusting combination locks for anything valuable
Combination locks can be brute-forced by sound or feel within an hour. Use them for helmets and shoes, not for bikes.
The final word
Choose among the current bike locks based on the bike's value, parking location and time left unattended. Alongside a suitable lock, record your serial number and ownership evidence, photograph the bike and register it with a service such as Bike Index or 529 Garage. Those records can help identify it if it is recovered.
