Best Bike Lock Buying Guide
Do you know how many bikes are stolen each year?
According to FBI statistics, the rate of bicycle rate is rising though other types of property theft are decreasing. It is found that approximately more than 1.5 million bicycles are stolen every year only in the USA. The growing demand for the bicycle as a sport and eco-friendly transport makes it one of the easiest targets for thieves.
On the other hand, Crime data expresses that the number of bicycle theft in the UK is 376,000 in each year. That means, every 90 seconds, one bicycle is stolen.
So, What to Do?
The best solution to your problem is to find a good bicycle lock. Any bicycle lock is designed to prevent bicycle theft. There are various types of bicycle lock such as U-lock or D-lock, Folding lock, Chain lock, and Cable Lock.
The most secure bicycle lock is the one that is large, heavy and portable. As a result, U-lock is recognized as one of the best bicycle locks which are too sturdy to break and can secure both wheels and frames to each other or to a fixed object.
What is U-lock?
U-lock, also known as D-lock, is a locking mechanism designed for securing a bicycle or motorbike when parked. You have to fasten the bicycle with the lock to a fixed object like a bike rack.
The name “U” comes from the strong U-shaped metal rod that has cutouts at each end and attached to a horizontal locking bar. As the U shaped shackle attached with a horizontal or straight locking bar, it forms a D-shape when you lock or secure something.
This horizontal locking bar or crosspiece is also made with solid metal. As a result, most U-locks are sturdy, robust and hard to break, offering protection for medium to high-risk theft areas.
U-locks are made of solid steel and very robust. These locks are too hard to break while cable locks can be cut easily. It is revealed that 90% of bicycle thefts were fastened with cable locks. So, buy U-locks instead of cable locks as U-locks ensure more resistance to cutting tools.
However, as U-locks are sturdy, it is heavy to carry and sometimes look awkward while carrying. Fortunately, bike lock brackets are also available to attach the lock to the frame for easy transportation. Instead of this situation, U-locks are the best solutions for securing your bike.
It is suggested to use U-lock with a chain lock for optimal security.
How to choose the right U-lock:
Understand your need and the level of security:
The first and foremost work is to understand what level of protection you need for your bicycle.
Before selecting any bicycle lock, try to understand your needs. If you are living in a high-risk area, you should go for a good lock and avoid a cheap one. But instead of your location, if you are riding on an expensive bike, you should choose a good and expensive lock.
So, how do you realize whether you are in a low risk or high-risk condition? Here are some tips:
|Diameter thickness||Cutting Possibility|
|Less than 13mm||Can be cut by medium size bolt cutters|
|13 to 15 mm||Can be cropped by only biggest bolt cutters|
|16 to 18mm||Cannot be cut by biggest bolt cutters|
However, it is also true that stronger and sturdier U-locks can be cut by stronger power tools like angle grinders. Unfortunately, you can do nothing for this except limiting the possibility of theft by buying U-lock with a thicker diameter. Usually, the thicker the diameter, the better the security will be. But thicker diameter will be heavy which leads you to think about the portability of the lock.
Portability is an essential thing to consider since people like to carry smaller and lighter one than a heavier one. The heavier lock will discourage you to carry, leading your bike to get stolen. U-lock transportability will depend on its size, weight, metal type and the quality of mount frame or bike lock bracket.
Generally, these mount frames are made with plastic that allows you to fix the frame with your bike in different places such as the top tube, the seat tube, the down tube or even the seat stays or handlebars.
A good frame is the one that can firmly attach the lock to the frame while you are riding. Though you can use a bag for carrying your U-lock, it is sometimes uncomfortable and can easily get wet or dirty. So, it is suggested to choose a U-lock that comes with a good mount frame.
Sold Secure Scale:
Without taking appropriate precautions about safeguarding your bicycle, your thousand dollars is a total waste. Your Payment will be back when you buy a good U-lock. An easy way to evaluate your bike lock is its security rating.
All lock manufacturers come with their own protection rating that shows how strong the equipment is. A higher rating indicates higher security and strength. In the majority of cases, better locks are more expensive while cheap locks give less security and become an easy target for the burglars.
Most of the bicycle locks are rated by the “Solid Secure” scale which is an independent and premium lock testing organization and certification house for security products. They give a podium-style rating of bronze, silver or gold for all the security products while bronze denotes the weakest and gold indicates the strongest. A list of approval categories and tested products with product brands will be found on their website.
|Security Level||Highest level||Higher level||Lower level|
|Protection||Best protection against optimistic thieves||Withstand determined thieves||Resist against opportunistic thieves|
|Tools protection||Can protect against a full set of tools for at least 5 minutes||Withstand attacks from an enhanced set of tools||Protect from basic set of tools|
|Suitable for||Best for bikes over $1000||Bikes less than $1000||Only cheap bikes|
|Perfect for area||Higher risk||Lower risk||Lower risk|
ART Foundation rating:
ART is another anti-theft prevention tester like “Sold Secure”. This Dutch organization gives a rating in 5-star scales where 5 stars are highest and 2 stars are accepted but less reliable. Try to find a lock with 3 or more stars. However, they rate less locking brands.
For example, in their security scale, popular New York brand Kryptonite gives rating 8/10 for a U-lock which is awarded a gold rating by Sold Secure. On the other hand, it gets 3/5 stars from Dutch lock testers ART.
So, while buying U-lock checks both manufacturers’ security scale rating and “Sold Secure” scale rating and approval which can be found here. If possible, buy gold or silver rated U-locks.
U-lock is one of the best ways to secure your bike. Though picking the right type of U-lock is difficult, you should check the above things such as the size of the lock, thickness, transportability, and security rating. Then you should also consider whether you are living in a high-risk area or not or where you need to lock your bike. The best secure bike locks are thicker, heavy and expensive. But again it depends on your circumstances where you need to use the lock.
