Best Bike Alarms Available in the Market Today

Let’s just go on and say it; bike theft is a big hassle. Imagine paying thousands of dollars on a rad bike, pimping it out with all the bells and whistles, only to have it stolen a short while later. That will be enough to make your blood boil a hundred times over. And, I don’t know about what experience you might have with bike theft, but I’ve had a few of my bikes stolen before, and they were rather expensive bikes.

Sometimes it’s the accessories I’ve saved up for and put on my bike that gets stolen, which is, granted, better than having the whole bike stolen, but is still a huge annoyance. There was even an instance where I had to ride my bike without a saddle because—you guessed it—it got lifted by a thief.


Anti-theft add-ons like locks and alarms are, therefore, an essential item to have installed on your bike. They add a layer of protection that can dissuade a thief from targeting your bike altogether.

A great system will be that which has both—the lock and alarm—working together to give your bike the optimum protection. Of course, not all bike locks and alarms were made equal.

Some are better than others, while others are much better than others. We understand that it will be challenging to get an idea about which product will be performing as advertised, which is precisely why we thought of creating this article.

Below, we’ll do a roundup of what we think are the best bike locks and bike alarms that are available on the market today. But before we do that, allow us to dedicate some pixels to discussing how you should choose the best bike lock and alarm for your two-wheeler.

How to Choose a Bike Lock and Alarm

As with almost everything, you can pretty much determine how well a bike lock and alarm system will perform by checking out its price. Naturally, the simpler the bike lock and alarm is, the more affordable it will be. To be sure, tandem bike locks and alarms that are simple aren’t all bad. Their utility will simply depend on where you keep your bike—and how you keep your bike. If your bike is parked in a moderately crowded area, then a simple lock and alarm mechanism will serve its purpose well.

In fact, there might not be a need for a more expensive system if the risk of your bike being stolen is low. Conversely, if you keep your bike parked in, how shall we say, a more shady area—or an area where theft is more probable—then you might want to go for something that is more expensive but works better at protecting your bike.

Ultimately, the type of anti-theft system that’s best for your specific circumstance will depend on you, so choosing a system will require careful consideration.

Some anti-theft systems are expensive, but they are made from more durable material, are more difficult for thieves to bypass, and have more than just one setting. Some can even have more than one utility to users. In other words, some, typically the expensive ones, are more than just anti-theft attachments to your bike because they can serve multiple purposes.

The more affordable bike anti-theft products will be pretty straightforward, and some will even be downright easy for thieves to break away from your bike while attracting a minimal amount of attention. In a nutshell, something affordable will always have some compromise in quality and performance, so this should be something you need to keep in mind.

Without further ado, below are the best bike lock and alarm systems we’ve found that are available on the market today.

The Best Anti-Theft Devices for Your Bike

Kryptonite Evolution Bracket

Kryptonite Evolution 11-14mm U-Lock with FlexFrame-U Bracket

Kryptonite’s Evolution 11-14mm U-Lock with FlexFrame-U Bracket is a great lightweight lock option for cyclists. It’s made of 11mm hardened steel, making it strong and secure, while still being light enough to carry around. The included FlexFrame-U bracket makes it easy to transport the lock in multiple locations. The higher security disc-style cylinder is also pick and drill resistant, providing an extra layer of protection.

Our Verdict

The Kryptonite Evolution 11-14mm U-Lock with FlexFrame-U Bracket is a great lightweight lock option for cyclists looking for added security without too much bulk or weight. It has received mostly positive reviews from customers on Amazon, and provides an extra layer of protection with its disc style cylinder. We recommend this product for anyone looking for a reliable bike lock that won’t weigh them down!

Bike Lock Anti-theft Alarm Bicycle Cable Locks


When you want to keep it simple, the Bike Lock Anti-Theft Alarm Bicycle Cable Lock will do a good enough job and give you peace of mind. And simplicity is the operative word here because the system is pretty straightforward.

With this, you’ll be able to secure your bike to a lamppost or a rail, and anyone who’s got the cojones to tamper with the cable will be greeted with a loud, piercing alarm sound. It’s no fun to the ears, trust us. And anyone around will be alerted to the deed.

The cable is long, flexible, and easy to manage, and we’re sure users won’t have a problem implementing it and hooking their bike to street furniture. The alarm is also loud and piercing (like we mentioned earlier), so you’d have to be a good distance away not to notice it when it goes off. Overall, the system is very easy to use. There’s nothing here that needs to be further explained as it is all pretty straightforward—and we think that this is all they will need for some people.

Of course, there are clear downsides. While the cable is strong, we fully expect a diagonal cutter to be able to break it with ease. Naturally, the alarm will go off should this happen, but if your bike is in an area where there are not too many people around, then there’ll really be nothing to dissuade an inveterate thief from taking off with your bike. If your bike looks like it’s worth $10,000 dollars, then you might be better off utilizing some other kind of anti-theft system.

Customers Reviews Analysis

This lock is a great product for cyclists looking for a secure way to protect their bike. Customers praising the lock’s ease of use and its anti-theft features. Many customers noted that the lock was easy to install and operate, with one customer noting that it was “very simple to set up and use.”

In terms of security, many customers were pleased with the lock’s ability to deter thieves. One customer noted that the “alarm feature is loud enough to scare away any thief,” while another said that they felt “safe knowing my bike is locked up securely.” Additionally, several customers commented on how durable the lock was, with one customer saying that it had held up well in all weather conditions.

Our Verdict

Overall, this is a great product for cyclists looking for a secure way to protect their bike from theft. The combination of its ease of use and anti-theft features make it an ideal choice for anyone looking for a reliable bike lock.

G Keni Bike Tail light, Intelligent Anti-Theft Bicycle Alarm


We liked this product, not least because it serves multiple functions, but we would suggest using it in tandem with another bike lock system because the G Keni’s anti-theft feature is simply an alarm. To be sure, it works great as an anti-theft alarm and will work by dissuading thieves with its loud and piercing sound. Indeed, the sound it emits is extremely loud and painful to the ear. It will take a really determined thief to still go through the process of stealing your bike once the G Keni is activated.

The alarm also serves multiple purposes. As we mentioned earlier, it’s both a bike bell and a tail light and can be placed unassumingly below the saddle, away from curious eyes. The whole system can be controlled via a small remote controller that is included in the package. It doesn’t require batteries and can be charged via USB—in addition, one full charge (which takes around 4 hours) will reportedly last 30 days. Moreover, the G Keni is that it is also waterproof—so you don’t have to worry about the device getting wet from the rain.

Like we mentioned, however, as an anti-theft device, the G Keni only offers an alarm feature and lacks the ability to keep your bike from being lifted and transported. So we think it will be best to install the G Keni in tandem with some other anti-theft system that offers a cable lock functionality or some such.

Customers Reviews Analysis

The G Keni Smart Anti-Theft Bike Alarm has been receiving overwhelmingly positive reviews on Amazon. Customers have praised the product for its convenience and ease of use. Many customers have noted that the alarm is loud enough to be heard from a distance and that it is easy to install. Furthermore, customers have also commented on the long battery life and the fact that it is waterproof.

Our Verdict

Overall, the G Keni is an excellent product for anyone looking for a reliable bike alarm system. It is easy to install and use and has a long battery life. Furthermore, it is waterproof and loud enough to be heard from a distance. We highly recommend this product for anyone looking for an effective bike alarm system.

Hiplok DX Wearable Keyed U-Lock


Sometimes, a thick hunk of sturdy, unbreakable metal is all you need to lock your bicycle into place and dissuade anyone from snagging it. And the Hiplok DX Wearable Keyed U-Lock might just be that hunk of metal that you need to carry around to secure your bike.

It’s pretty simple and straightforward, but it works. Oh, boy, does it work. It’s made from a premium hardened steel, and, trust us, it will take a power tool to cut through this thing. It also comes with a clip that you can slip into your waistband to carry the lock when riding your bicycle. It’s simple, useful, and nearly impossible to break without a power tool.

The downside to the Hiplok DX is that it doesn’t have an alarm feature. Some might think an alarm feature is essential, some might not, but we believe that this will work just fine for specific situations.

Key Features To Look For In Bike Alarms

The sound of a bike alarm piercing through the air is like an urgent call to action: something needs your attention. From a loud, mechanical buzzer to a more subtle chirp, these alarms can alert you and deter potential thieves from taking your prized possession without permission.

First off, consider wireless technology. With this type of alarm, sensors detect motion near your bicycle and send a signal to your receiver or smartphone app—allowing you to be quickly alerted if someone tries to take it away. Many modern systems also come with GPS tracking capabilities, which makes locating stolen bikes easier than ever before. Plus, there’s no need to worry about wires being cut by intruders; wireless alarms provide added protection against tampering attempts.

When selecting an alarm system, think durability as well. It goes without saying that any bike alarm worth its salt must have sturdy construction capable of standing up to bad weather and other harsh conditions over time. Look for waterproofing and dustproofing ratings as well as shock resistance ratings when searching for the best option available.
