Bike Lock Buying Guide
Considerations When Purchasing A Bike Lock
Types of Locks
Typically, a power tool is needed to get into a U-lock. They are usually a more expensive and heavier option than its competitors since it uses hardened steel in its construction so you can’t cut it with a hand tool. Some versions use a double deadbolt feature meaning you need two cuts to open the lock which is a great deterrent to a thief that doesn’t want to waste the extra time.
If it is made with hardened steel and has a durable shackle, a chain lock can rival a U-lock in security. Don’t use a standard gym class combination lock with a store-bought chain that can be easily cut with a set of bolt cutter. Find a larger chain that will have the ability to lock up your bike frame as well as both wheels to a post or tree.
A popular alternative to the cable and chain lock, the folding lock features a low profile when they are folded making them a perfect choice for a commuter. Security wise, they are no match for a power drill or bolt cutter, but they do allow you to lock up larger objects that a U-lock can’t.
Known as the least secure lock type, the cable lock is inexpensive making them a popular choice. These lightweight locks wrap easily around a bike frame but they are easily defeated by a set of bolt cutters. This is a good choice from a low crime area where you are only interested in protecting your bike from someone that might just walk off with it.
Key Lock Versus Combination Lock
As far convenience, a key is obviously handier and faster to use than a combination lock. Keep in mind that you can lose a key. With a combination lock, you won’t have a key to lose, but you can forget the combination. Which is better is really up to personal preference.
Another feature determined by personal preference is the weight of a bike lock which can get pretty heavy depending on the model. Your choice will definitely be influenced on whether you want to be carrying that extra weight around as you ride your bike. It isn’t as much of a problem for those that only occasionally take out their bike, but someone that work as a bike messenger will want to find the best lightweight bike lock that’s on the market.
How to Use Your Lock
It’s a good rule of thumb to lock your bike according to value meaning you want to lock up the most expensive part first which is the frame. Then lock up the rear wheel before the front. If you lock up both wheels to the frame using a cable or chain lock, you have the best chance of not having your bike stolen.
Remember to lock your bike in a well-lit area and never leave your lock on the ground as a thief can use that position for leverage when prying it open. Make sure what you are locking your bike to is stronger than your lock and that it isn’t something the bike can be lifted up and over like a small tree or pole. You can increase your security by also registering the serial number for your bike with the local police department so they can return it if it is stolen and found.
What’s the best bike lock?
Typically, the standard U-lock is considered the best lock for most of the extreme circumstances your bike can be stolen in.
Is It Possible to Break Through A Bike Lock?
There isn’t a lock on the market that can’t be broken into. The question you want to answer is, how hard is it to break into? A low-end lock that is easy to break into will be a prime target versus a well-engineered lock constructed of a high grade and thick hardened steel that an experienced thief will avoid because it is too much to work to break open.
What’s the Difference Between A U-Lock And A D-Lock?
They are both the same thing. U-locks are called D-locks in Great Britain. So, it really depends on the manufacturer and what geographical area you are in.
Having a well-designed bike lock can make a big difference in whether or not a thief is going to take the time to break your lock. Make sure you choose a lock that is appropriate to the area where you lock your bike and always lock up your bike correctly to ensure your lock will be able to work properly.
