Frequently Asked Questions (FAQs)
What is the strongest type of bike lock?
Generally, heavy-duty U-locks with shackles thicker than 16mm, like the Kryptonite New York Fahgettaboutit, offer the highest protection. They are difficult to cut with manual bolt cutters.
Is a U-lock better than a chain lock?
U-locks usually offer a better weight-to-security ratio, but chains like the Kryptonite Evolution are easier to lock around large objects. U-locks are better for standard racks; chains are better for versatility.
How do I properly lock my bike?
Always lock your frame and rear wheel to an immovable object. If possible, use a secondary cable or lock to secure the front wheel. Keep the lock off the ground to prevent leverage attacks.
Can bolt cutters cut through these locks?
Locks with shackles 16mm or thicker are extremely difficult to cut with manual bolt cutters. Smaller locks (under 13mm) are more vulnerable, so choose based on the risk level of your area.
Do these locks come with a warranty?
Most reputable brands like Kryptonite, Abus, and OnGuard offer warranties. Some even offer anti-theft protection programs that pay out if your bike is stolen due to lock failure, provided you register properly.
