Here are five top tips on buying the best bike lock:
1. Buy the correct standard rating for the value of your bike
The majority of bike locks are rated on a ‘Sold Secure’ scale and are given a podium style rating of Bronze, Silver or Gold. Unsurprisingly, Bronze is the weakest and Gold is the strongest.
What you must realise is that bike insurance policies won’t pay out on your stolen bike if you use anything less than an approved locking device
2. The price
While it’s not always an indicator on quality, in the bike lock world, generally, you get what you pay for. A cheap lock will offer little resistance to a thief. A good bike lock will cost in the region of £30 to £50.
3. D locks
Bike locks don’t come sturdier than this. It is generally accepted that U locks (or D locks whatever way you look at them) are the most durable and the first choice of security for many cyclists.
You’d think that the larger the U lock the better, but this allows the thief to manoeuvre in and around your bike and create enough leverage to force open a lock. Smaller ones give less room to 'do the job'. They are also lighter to carry. And don't think a smaller u-lock isn't as strong. The thickness of the lock isn't dependant on the overall size.
4. Chain locks
Chain locks are robust and heavy – the majority of chain saws won’t be able to chew their way through it. However, such a heavy chain requires an extremely strong padlock. This is the weak point of the lock and catches out many cyclists. Look for one that is made from hardened steel. Remember, the chain is only as strong as the lock.
5. Avoid cable and combination locks
While cable locks may be light to carry and easy to transport on your bike, they are susceptible. They can be cut through and the locking mechanism is ‘easy’ for a thief to break. It’s also best to steer clear of combination bike locks. Combinations can be worked out – why give the opportunist thief a chance?
