How to Choose the Best Bike Locks
You buy a bike lock to keep your bike from getting stolen. But there are a lot of bike locks out there! So, how do you choose the best bike lock for your bike? Here’s a quick 3-step guide to help you get started.
Step 1. Get the right level of security
To determine the right level of security you need for your bike, we need to assess your risk first. Refer to the table below:
University, city, or big towns
Villages or small towns
How do you intend to park your bike?
Over one hour
Less than one hour
Is your bike attractive?
You will need a high-security lock if you answered two or more yeses on the high-risk column. If you have two or more yes answers on the low-risk column, a lower security lock will do.
Step 2. Choose your type of bike lock
Now that you have a good idea of how much protection you need, it’s time to choose the type of bike lock to buy. There are at least three main types of bike locks in the market. These are:
Cable locks – flexible and lightweight bike locks that you can store and transport easily. These locks provide a basic deterrent for low-risk areas. Cable locks are usually locked with a combination lock. If you are living in medium and high-risk areas, don’t use cable locks as your primary deterrent as these can be cut by bolt cutters in less than a minute.
Chain locks – these locks are made from hard metal links that are chained together. Chain locks are usually locked with a padlock and key. Depending on your needs, these locks come in a variety of weight, strength, and size. Heavier chain locks offer more protection than lighter ones but are less portable. Chain locks are a good visual deterrent and will require power cutting tools to break.
U-locks – these bike locks look like a giant padlock. Protecting bikes since the 70s, U-locks features a tested and proven design that’s resistant to leverage attacks, drilling, and picking. High-quality U-locks are highly resistant to bolt cutters. They can come in varying sizes, weight, and strength. Best used in combination with chain locks. With U-locks, make sure you have a tight fit to reduce the space thieves can use for a leverage attack.
Step 3. Go with trusted brands
Always avoid knock offs. Your bike is a major investment and the last thing you want is to cheap out in keeping it safe.
Tips on How to Keep Your Bike Safe
Your bike is a major investment. And it’s a waste to see it in the wrong hands because you failed to protect your bike against theft. Below, we’ve listed some of the top tips on how to keep your bike safe. Read on.
1. Invest in a high-quality bike lock
Your bike lock is your number one deterrent against bike theft. So, investing in reliable and high-quality locks is a must. Remember that with the right tools, any determined thief can still get through your lock. Here’s a way to give them a very, very hard time:
- Don’t use cable locks. Any garden cutters can get through these.
- Use heavy-duty bike chains and U-locks for the best protection.
- Don’t just lock the bike frame. Lock your wheels too.
- Always use two U-locks to secure the front and rear of your bike. You can also use different set of locks. For example, a U-lock for the front and a heavy-duty chain lock for the back. This way, the thief will be forced to use different tools and strategies to get your bike — making it riskier and time-consuming for them.
- Get the smallest U-lock that fits your bike. The smaller the lock, the less space the thief has for leverage.
2. Register your bike
We all register our cars, so I don’t see any reason why you should not register your bike. Bike registration is not expensive and it increases the likelihood of recovering your bike in case it gets stolen. Your city or independent organizations in your area should have this service.
Registering your bike is easy. All you need is the manufacturer, model, and serial number of your bike. You will then receive a unique code associated with your bike. Some bike registration services give warning stickers alerting bike thieves that your bicycle is registered.
3. Install a GPS on your bike
Take advantage of technology! If you consider your bike as a valuable investment, then you should install a GPS tracker on it. Most trackers for bikes look like standard bike components like a top cap or bike light — thieves will not even know it’s there. GPS trackers can transmit a signal so you can pinpoint the location of your bike in case it gets stolen. Some models even have a feature that notifies you when your ride is moved.
You can also install a bike alarm that works in the same way as car alarms.
4. Avoid parking in the same spot every day
Do you know that most bike thieves work in groups of three? The first person scouts the area for vulnerable bikes while the second accomplice brings in the tools to free your bike. The last person will then simply ride away with your bike.
Parking your bike on the same spot every day allows these criminals to create a plan of attack. Don’t be deceived by the false sense of security offered by your “favorite” parking spot.
5. Bring your bike inside
Don’t leave your bike exposed on the streets or in the hallway. If you can, bring it inside where it can be safely stored. This tip applies to all instances — whether you are at work or home. There are a lot of bike storage solutions available for all types of spaces.
6. Lock your bike ALL the time
Even if your bike is parked in a closed garage or balcony, always lock your bike. Believe it or not, bike thieves are masters of their craft. Some of them are so good they can even steal bikes on second-floor balconies!
Frequently Asked Questions
Types of Bike Locks
Bike locks come in various types and sizes. There are at least three common ones:
1. Chain Locks
Made of steel links, chain locks can be built into a combination lock or a padlock. Chain locks are long. The most common ones can reach up to 6 feet — long enough to around your bike’s front and rear wheels. This type of bike lock is usually covered in nylon or vinyl to protect your bike’s frame from scratches.
Chain locks are heavy. So, if you worry about taking too much weight while biking around the city, pick a different type of bike lock instead.
2. Cable Locks
Cable locks are usually made of coiled wires of varying length and thickness, covered in nylon or vinyl to protect your bike’s finish from scratches. Like chain locks, this bike lock can also be built into combination locks or padlocks. Because they’re light, cable locks are a favorite among bike commuters.
The convenience cable locks offer has a serious downside. Compared to the other two types of bike locks, it’s the weakest. Because of this, cable locks are not reliable deterrents to scare away bike thieves.
U-locks are at the sweet spot between convenience and security. Made from steel, they’re very tough and offers great visual deterrent for thieves. It’s also lighter compared to chain locks, making it easy to carry around when biking in the city.
U-Locks have a solid crossbar, which when removed, allows the “U” to wrap around your bike’s frame and a post. Replacing the crossbar locks the “U” into place.
If you’re lucky enough, you can even get a U-Lock with a cable lock that you can wrap around your bike’s wheels.
Types of Bike Locks
If you really want to secure your bike from bike thieves, you need to know how to lock it properly. Here are some tips:
When locking your bike in the street, make sure you choose a busy place. Bike thieves are not comfortable “working” with many people passing around.
Choose a place with CCTV coverage. If your bike gets stolen, a CCTV footage can help identify the thief and help recover your bike.
Choose a place with lots of bikes already locked up. With a lot of bikes to choose from, thieves will most likely go for a badly locked bike. More bikes mean less space for thieves to maneuver their gears.
Lock your bike on an immovable object such as railings. Avoid trees, sign posts, chain link fences, and wooden posts as much as possible.
If you are going to a restaurant, a cinema, or any places where you’ll obviously take significant time, consider locking your bike a couple of streets away. Why? Because when thieves see you enter these premises, they’ll know they have more time on their hand to do their dirty work. Don’t give them this clue.
Always lock your frame. Many cyclists carelessly secure their bikes through the wheel.
Keep your bike locks elevated. Locks that are close to the ground can be broken when smashed with a hammer against the hard floor. The floor can be also used by thieves for added leverage!
Position your bike lock so its difficult to access. If you can position it facing downwards, all the better!
Another great way to secure your bike is to use more than one lock or a combination of the locks we’ve discussed above. When thieves see that your bike is secured by two or more locks, they are more likely to walk away and find an easier target.
For U-Locks, fill the inside space as much as you can. Feel free to include the pedal, chain, and even wheels when locking your bike. U-Locks are known for the security they offer but they aren’t safe from a bottle jack attack. Prevent thieves from using this method by giving them less space to work on.
Keep your bike secure at all times! It’s a big investment. So, protect it with the best bike locks you can find. For an added layer of protection, consider getting it registered as well. The authorities are not getting better at handling bike theft cases and there are several organizations that keep tabs of your bike for a minimal fee.
