It boasts a Security Level 9 with hardened steel components, offering strong protection against theft.

ABUS 2023 Framelock Granit Xplus 6950M AM R BK, Key Not Rremovable When Unlocked, Fits Most Bikes, (1-Pack)
The ABUS Granit Xplus 6950M is notable for its universal compatibility across most bike frames, making it a flexible choice for riders with different bikes. Its key remains in the cylinder when unlocked, which is convenient for quick access, though this feature could potentially be a security vulnerability if not managed properly. The lock features an 8.5 mm shackle of hardened steel, offering high security. Compared with other options, this lock balances security with ease of use, but its weight at 1.70 pounds makes it less ideal for those seeking a lightweight solution.

How We Picked
My selection process focused on premium frame mounted locks that combine high security with ease of use and installation.

I compared security levels, build quality, user convenience, and tradeoffs like weight and size to recommend options suitable for serious cyclists who want reliable theft deterrence.
Factors to Consider When Choosing Frame Mounted Locks Premium
Choosing the right premium frame mounted lock involves balancing security, compatibility, weight, and convenience. High-security locks like the ABUS 4750X are excellent for large bikes and e-bikes but come with added weight and installation considerations. The ABUS Granit Xplus offers a versatile fit and ease of use, perfect for riders with multiple bikes or those who prioritize quick access. The Trelock RS 481 XL excels with wide tires and high security certification but may weigh more than some users want. Understanding your bike’s specifications and your security priorities will help determine the best fit.Security Level and Build Quality
High security is vital for preventing theft, especially for expensive bikes. Look for locks with certifications and hardened steel components. The ABUS Level 9 and Trelock Level 13 locks offer strong protection, but higher security often means more weight and complexity. Balance your security needs with your bike’s value and typical usage environment.
Compatibility and Fit
Ensure the lock fits your bike’s frame and tires. The ABUS 4750X is ideal for large wheels, while the Trelock RS 481 XL is designed for wide tires. The ABUS Granit Xplus’s universal mounting makes it flexible for different bikes. Measure your bike’s frame and tire width to pick the best fit.
Ease of Use and Portability
Features like keys that stay in when unlocked or multiple mounting options enhance convenience. However, heavier locks, such as the Trelock or ABUS 4750X, may be less portable. Decide if weight or quick access is more important for your riding style.
Frequently Asked Questions
How secure are frame mounted locks compared to U-locks?
Frame mounted locks generally offer high security, especially when certified at high levels like ABUS Level 9 or Trelock Level 13. However, they are typically less portable than U-locks and often need to be supplemented with secondary security devices for maximum protection. The advantage is convenience and integration with the bike frame, making them harder to cut or pry open when used correctly.
Can I use these locks on any bike?
While most of these locks are designed for broad compatibility, it’s important to check their mounting options and passage widths. The ABUS Granit Xplus provides the most universal fit, while the ABUS 4750X is best suited for large wheel bikes. The Trelock RS 481 XL is ideal for bikes with wide tires. Always measure your bike’s frame and tires before choosing.
Is the weight of these locks a concern?
Yes, especially with high-security models like the ABUS 4750X and Trelock RS 481 XL, which tend to be heavier due to their steel components and wider passages. If you prefer a lightweight setup for commuting or frequent use, consider how much weight you’re willing to carry or mount.
Do these locks come with alarms or electronic features?
No, these models are purely mechanical frame mounted locks. They focus on physical security and ease of use but do not include electronic alarms or GPS tracking. If electronic features are important, you may need to look at different lock types or add-on devices.
How important is security certification?
Security certification, like those from Sold Secure or equivalent testing agencies, provides assurance of the lock’s resistance to common theft methods. Higher certification levels generally mean better protection, but also often come with increased weight and cost. Prioritize certification if your bike is a high-value asset or parked in high-risk areas.
Conclusion
For riders prioritizing maximum security for large or high-value bikes, the ABUS 4750X NR is the best fit despite its weight and need for secondary locks. Those seeking a versatile, easy-to-use lock that fits most bikes should consider the ABUS Granit Xplus 6950M, especially if quick access is a priority. Meanwhile, cyclists with wide tires and a focus on high safety levels will find the Trelock RS 481 XL ideal, provided weight isn’t a concern. Your choice should align with your bike’s specifications and your security needs, balancing weight, compatibility, and ease of use.
