To properly fit a bike lock and maximize security, you need to secure the frame, and ideally a wheel, to a sturdy, immovable object like a bike rack.
Here's a breakdown:
1. Choosing the Right Lock:
- U-Lock (or D-Lock): Offers high security, especially when used correctly.
- Chain Lock: Provides flexibility in locking locations, but can be heavier.
- Cable Lock: Offers low security; best used as a deterrent or secondary lock.
2. The Best Locking Technique:
-
Target a Secure Object: Always lock your bike to a solid, immovable object like a bike rack, sturdy pole, or designated bike parking structure. Avoid flimsy fences or signs.
-
Prioritize the Frame: The most important thing is to lock the bike frame. Pass the lock through the frame (ideally the rear triangle) and the secure object.
-
Include a Wheel (if possible): If your lock is large enough, also pass it through at least one wheel. The front wheel is usually easier to remove than the rear.
- With a U-Lock: Pass the U-Lock through the rear wheel, the frame (rear triangle), and the secure object.
- With a Chain Lock: Wrap the chain around the secure object, through the rear wheel, and the frame, securing it with the padlock.
-
Tighten the Lock: Minimize the space within the U-Lock or chain. This makes it harder for thieves to insert tools to break the lock.
-
Consider Two Locks: For higher security, especially in high-theft areas, use two different types of locks. For example, a U-Lock through the frame and rear wheel, and a cable lock securing the front wheel.
3. Key Considerations:
- Placement Matters: Position the lock so the keyhole faces down, making it harder to pick or tamper with.
- Avoid Quick-Release Levers: Consider replacing quick-release levers on your wheels and seat post with bolt-on versions. This reduces the risk of parts being stolen.
- Register Your Bike: Register your bike with a national bike registry. This can help authorities recover your bike if it's stolen.
- Make Your Bike Less Attractive: Make your bike look less appealing to thieves by making it look older or less valuable.
In Summary: Always lock your bike frame and at least one wheel to a solid, immovable object using a quality lock. Consider using two locks for added security, especially in high-risk areas. The goal is to make your bike the least appealing target on the rack.
