If you’ve read London Cyclist for long enough then you’ll know about our roundup of the best bike locks.
In there we talk about the importance of a heavy D-lock for your security.
However, as any seasoned London cyclist will tell you, this should always be complimented by a secondary lock.
Your primary lock goes around your frame and back wheel. The secondary lock then goes around the front wheel and the frame.
Without a secondary lock it would be easy for someone to steal your front wheel.
Also, thieves don’t tend to carry the tools required to break two different types of lock. Therefore, they are less likely to get away with your bike.
Don’t worry; we’ve got a list of the best secondary bike locks to compliment your existing lock. Now all you have to do, is figure out which one is best for your bike.
Choosing A Secondary Lock
You probably spent lots of money on bicycle accessories from your saddles, to pumps and jackets, but you worry about cost when it comes to the security of your bike.
Remember that a cheap secondary lock will likely provide cheap security that is easy to breach. This doesn’t mean you need to break the bank on your secondary bike lock, but it should be sufficient enough to back up the primary lock.
Don’t let a heavy secondary bike lock deter you from it as there are plenty of lightweight yet effective locks on the market. Besides any seasoned cyclist can carry around an extra kilo or two. If not, there are plenty of secondary locks that are small enough to fit in a sack, around your waist or on the frame.
Here are some of the best options we’ve picked out.
Best Secondary Bike Locks
Flex-O-Steel is an apt name for this cable lock because it comes with an outer layer of hardened steel that protects the cylinder lock while keeping it flexible. The automatic locking and unlocking mechanism means cyclists—especially couriers—don’t waste precious time locking it down. Not as heavy as other cable locks at just 1.1 kilograms, it’s lightweight and convenient to transport.
When combined with a D-Lock you can feel confident your bike is secure.
Available from Amazon for around £30.
Knog Party Frank Bike Lock
If you’re looking for a traditional but inexpensive back up lock, Knog Party Frank is it. Made with a braided steel cable with scratch-less PVC, a fibre core and a unique key design, offering an enhanced level of security. This is definitely not your father’s cable lock.
The lightweight Party Frank lock can easily wrap around the bike, your wrist or backpack so it is easy to carry. Although it seems flimsy, as a secondary bike lock you could do worse than this coil lock. Thanks to the scratchless PVC lining, you also have no chance of scratching your frame.
Available from Amazon for around £15
Kryptonite Kryptoflex Coiled Key Cable Lock
This trusty Kryptonite bike lock provides the perfect blend of a lightweight design with sturdy protection and a Talon lock pick retention system. With a 360-degree rotating lock head you won’t have to contort your body just to lock up your bike!
What’s more, the Kryptoflex coils up easily for transport and the cable is long enough that you can secure the bike around most bike racks, lamp posts and fences.
Available from Amazon for £18
Hiplok V1.50 Wearable Chain Lock
The fact that the Hiplok is wearable is one of the biggest selling points because you don’t have to lug around a heavy lock, but instead can just strap it on and go. This is the ideal secondary bike lock for those who use their bikes for to travel without a bag or purse weighing them down.
Your Velcro strap acts as a belt while you’re cycling and it’s expandable to about 112cm for every size cyclist. Secure the bike by bringing the chains together and you’ve got a pretty nifty back up lock. It’s convenient, if a little heavy (1.8kg) but somewhat pricey for a secondary bike lock.
Available from Evans Cycles for £62
While these bike locks provide sufficient security, we recommend only using them with a sturdier primary bike lock to provide the best protection for your bicycle.
