How to Lock Your Bike Properly: A Practical Security Guide
Most bike theft is opportunist — a thief takes the easiest bike on the rack. The goal of locking well isn't to make your bike impossible to steal; it's to make it more trouble than the one next to it. Here's how to do that.
The principle
Lock the frame to something immovable, secure the wheels, spend a sensible fraction of the bike's value on the lock, and pick your spot carefully.
Lock the frame, not just a wheel
Always pass the lock through the frame and around a solid, fixed stand — never just the front wheel, which pops off in seconds. A D-lock through the rear triangle and the stand is a strong, simple default.
Secure both wheels
Quick-release wheels are quick to steal. Use a second lock or a cable for the front wheel, or swap to locking skewers. Take lights, computers and bags with you.
Buy a lock worth the bike
A cheap lock on an expensive bike is a false economy. As a rough guide, budget around a tenth of the bike's value on the lock, and look for a Sold Secure rating. Two different lock types (a D-lock plus a chain) beat one.
Choose the spot
- Busy, well-lit, ideally covered by cameras
- A proper fixed stand — not a flimsy railing or a signpost you can lift it over
- Keep the lock off the ground and the keyhole facing down
And before you ever lock up: register the bike and record the frame number — so a good lock is your prevention and a registration is your recovery.
