Conclusion: frame locks

AI
Choosing the right frame lock depends on where you park and how much time you leave your bike unattended. Whether you need a basic deterrent or a high-security immobiliser, our curated list has you covered. Explore the full selection to find your ideal match.

Frequently Asked Questions

AI
For very short stops, they are convenient deterrents. However, for long-term parking or high-theft areas, it is highly recommended to pair a frame lock with a chain or U-lock to secure the bike to a fixed object.
Most are designed for standard frames, but compatibility depends on the seat stay thickness and the presence of mounting holes. Always check if your bike requires a specific adapter or a universally adjustable model.
Security levels typically refer to the resistance of the locking mechanism and the thickness of the shackle against cutting tools. Higher levels offer more protection but may be slightly heavier or more expensive.
