It’s important to make it as hard as possible for would-be bike thieves to steal your bike. We encourage bike owners to invest in a decent lock, and register their bikes with 529 Garage.
Using a bike lock
Choose the right lock and you’ll be far less likely to have your bike stolen. A good rule of thumb is that you should spend 10% of your bike’s value on a lock.
- Always lock your bike through your bike frame and the rear wheel to a solid object, preferably a solid bike stand.
- We recommend checking the independent security rating Sold Secure (Diamond, Gold, Silver or Bronze) before purchasing your lock, especially if your bike is high value.
- The stronger the lock the better. D-locks are usually the strongest, or there are also chain locks or foldable locks. Avoid flexible spiral cable locks – they’re easy to cut.
- The stronger the lock the better. D-locks are usually the strongest, or there are also hardened steel chain locks or foldable locks. Avoid flexible spiral cable locks and galvanised chain locks - they’re easy to cut.
A guide to bike locks
-
D-lock
D-locks are made of heavy D-shaped steel bars. They’re generally the strongest lock of all, and worth the investment. The most secure way to use these on most bikes is to skewer them straight through the rear wheel, around the bike frame.

-
Chain lock

Chain locks are flexible and made of solid steel links. The thicker the better for these locks, ideally 8mm plus.
-
Foldable locks
Foldable locks are relatively strong, practical and flexible. They can be folded up nice and small, and usually come with a handy mounting pouch for easy carrying.

-
Cable locks

Cable locks are easily cut and should not be used as a primary lock. They can be useful for securing your front wheel to help avoid wheel theft.
