ABUS Pro Tectic 4960 Frame Lock
The ABUS Pro Tectic 4960 is a rear-frame lock designed for quick securing of a bicycle. It features an 8.5 mm thick shackle and a hardened steel body, providing a robust deterrent against casual theft. Best for urban commuters who frequently make short stops and need a compact lock that can be mounted to the frame for immediate use. The lock housing accepts accessories to expand security options. A potential limitation is its frame-fit constraint; verify the mounting area on your bike to ensure compatibility with your frame’s geometry.
Best for: City commuters and riders who value fast, on-frame security without carrying a separate padlock.
Why chosen: Combines compact size with strong construction, making it a reliable quick-lock solution for daily errands.
Caution: Confirm compatibility with your frame shape and clearance around the derailleur and rear wheel.

This frame lock is a heavy-duty, one-push locking system with a 65 mm opening and a mounting bracket included. It’s designed for quick, reliable wheel immobilization, suitable for mountain bikes, cruisers, and road bikes. The solid construction features a hardened tongue and protective coating for weather resistance. Best for riders who want a straightforward, secure lock that’s easy to operate and mount. A limitation to consider is its fixed opening size—bikes with tires wider than the opening may not fit.
Best for: Riders needing a robust, easy-to-use frame lock with quick operation and a reliable mounting solution.
Why chosen: Easy one-push mechanism reduces handling time during quick stops while offering strong resistance to common theft methods.
Caution: Check tire width and frame clearance before purchase to ensure a proper fit.

It includes a hardened bracket and an anti-drilling cylinder for enhanced security. This model also supports plug-in options for chains or cables, increasing overall security when used in conjunction with other anti-theft devices. A potential limitation is the need to pair with plug-ins for extended security, which may require additional purchases.
Best for: City bikes and e-bikes with wide tires that require extra clearance for secure mounting.
Why chosen: The extra-wide opening and high-security features offer strong protection without obstructing tire clearance.
Caution: Consider adding plug-ins for complete theft deterrence when parking in high-risk areas.
NDakter Heavy-Duty U Lock with Chain
The NDakter lock set features a heavy 3T manganese steel U-lock and a 4-foot chain, designed to resist cutting and leverage attacks. The 0.57 inch (14.6 mm) shackle thickness adds strength, making it a strong deterrent in high-theft zones. With a 4-digit resettable combination, it eliminates the need for keys and reduces risk of key loss. The shackle is coated to minimize bike surface scratches. Limitation: The overall weight is substantial, which may reduce portability for some riders, and no bracket is included for mounting the chain and lock on all frame types.
Best for: Riders in high-theft areas seeking maximum physical security with a keyless option.
Why chosen: The combination of a thick, hardened shackle and long chain provides versatile, heavy-duty protection when secured to a fixed object.

Why chosen: The one-push design plus an adjustable mounting bracket offers an unobtrusive, fast security option for daily use.
Buying Guide: Key Considerations for Rear Wheel Locks
- Lock type and opening size: Frame locks are quick to use and mount, while U-locks with chains offer greater length and flexibility. Check opening diameters to ensure your tires or fenders fit without interference.
- Security level and materials: Hardened steel, anti-drilling cylinders, and thick shackles deter thieves. Consider hardened brackets for extra protection against leverage attacks.
- Bike compatibility: Frame lock mounts must fit your frame diameter and geometry. For wide tires, choose locks with wide openings or additional plug-in options.
- Portability vs. permanence: On-bike frame locks are lightweight and always accessible, while U-locks with chains are heavier but offer flexibility for securing to fixed objects.
- Weather resistance: Coated surfaces resist rust and corrosion. Outdoor storage conditions should guide material choices.
- Installation and mounting: Look for adjustable brackets and clear installation instructions to fit various frame sizes and shapes.
- Security accessories: Some models offer plug-in chains or cables for extended security; plan for additional components if needed.
Frequently Asked Questions
- What’s the difference between a frame lock and a U-lock? A frame lock attaches to the bike frame and immobilizes the wheel quickly, ideal for short stops. A U-lock provides robust security when used with a chain or cable to secure the bike to a fixed object, suitable for longer parking.
- Is a wider opening better for tires? Yes, wider openings accommodate balloon tires and wide fenders, but ensure fit with your frame and wheel width.
- Do I need additional accessories? Some frame locks support plug-in chains or cables for enhanced security; consider these if you park in higher-risk areas.
- How important is a hardened shackle? Highly important; a thicker, hardened shackle is harder to cut or pry and increases overall resistance to theft attempts.
- Can I mount these on any bike model? Mounting compatibility varies by model and frame design; verify frame diameter, mounting points, and tire width before purchasing.
- Are keyless locks safer? Keyless options reduce key loss risk but require careful handling to avoid forgetting a combination. Always document or memorize the combination securely.
