5 Best Bike Alarms in 2022 – Reviews & Top Picks

Planning to deter thieves from stealing your exorbitantly-priced bike? If so, you must pair your bike with a sound, reliable bike alarm system for additional security.

A well-functioning alarm not only alerts the owner of the impending threat but also sounds off to keep the bystanders in the loop, thus discouraging the thieves from making a move. Of course, the modern versions lock the bikes in place too.

How do the bicycle alarms operate exactly, you ask? More often than not, the top bike alarm devices are powered by batteries, either rechargeable or replaceable with fresh replacement batteries.

Bicycle alarms are usually constructed in a portable and compact manner for the rider’s convenience. Boasting a discreet fitting, bike alarms need to be installed in areas where movements and vibrations are felt the most.

Also, if bike thieves are successful in stealing your bicycle, you can rest easy knowing that bike tracking is possible because of the GPS locators integrated into the bicycle alarms. No one, not even the deftest of thieves, will be able to escape freely.

Now, there isn’t a dearth of alarm security system available for bicycles on the market, and choosing from the sea of products can be a daunting task. Plus, it doesn’t help that not all of them function as advertised.

Fortunately, I’m here to keep your worries at bay. After thorough research and some experiments, here’s a review of some of the best bicycle alarm devices worth their weight in gold.

Top 5 Best Bike Alarms – Our Reviews:

1. G Keni Tail Light Anti-Theft Alarm

What I like about the G Keni Tail Light Anti-Theft Alarm system the most is its discreet placement. This alarm can be either installed right under your seat or along with the post.

Of course, I also love the fact that it comes with a plethora of safety and deterrent features.

For instance, as its name suggests, the alarm comes with tail light features, an anti-theft alarm that sounds off even with the slightest of vibrations, and a bike finder location sound that allows you to locate your bike from a 50-foot radius with remote control.

In addition to that, the Anti-Theft Alarm also comes equipped with an enviable selection of lock degree, allowing you to choose a setting that goes best with the surroundings you’re in. Plus, the LED lights make the alarm extremely easy to locate under dimly lit areas.

If you’re in search of a bike alarm that prevents bike theft and allows you to maintain a high level of visibility at night, the G Keni Tail Light Anti-Theft Alarm will work as the best bicycle lock for you.


  • Charging via USB
  • Quick and easy installation process
  • Durable enough to stand the test of time
  • Affordable purchase price
  • Well-functioning remote control


  • Triggered by even the slightest of vibrations

2. SmartHalo Bike Smarter

Next on this review is the SmartHalo Bike Smarter which works exactly as advertised. It does its “smart” name justice by providing a wide variety of features such as GPS and navigation, night light, fitness tracking, and phone notifications.

However, what makes it truly smart is the fact that it allows you to monitor your bike from your smartphone. Of course, it works as an alarm too, producing a blaring noise every time it detects motion, persistent meddling, or a sign of a threat.

The fitness tracker settings on the SmartHalo Bike Smarter must also be given their share of the plaudits. After all, they perform a terrific task of providing info related to distance traveled, time taken, calories burned, average cycling speed, and more.

Unfortunately, all’s not great with the SmartHalo Bike Smarter. This device has a tendency to provide unsuitable routes at times.

Leaving that tiny bit of drawback aside, it offers plenty for its price range.

Made in Montreal and shipped to the United States and other parts of the world, this one is for tech-savvy cyclists who are in the hunt for an alarm that can do more than just alert you of theft.


  • Best smart bike lock around
  • Offers a variety of features, settings, and functions
  • This one-of-a-kind bike alarm allows you to track your bike from your smartphone app
  • Best suited for tech-savvy riders
  • Positive online reviews


  • Inaccurate navigation system may be a deal-breaker for some
  • May not sync as well as you’d like with your smartphone

3. Wsdcam 113dB Wireless Anti-Theft Alarm

Unlike other complicated bike alarms on the market, the Wsdcam 113dB Wireless Anti-Theft is relatively easy to install. It attaches to the frame of your bike with minimum fuss.

What I love about this motion sensor alarm the most is the fact that it comes with seven customizable vibration options, allowing you to choose or set how the alarm responds to different stimuli. Therefore, if you don’t like sensitive alarms that go off at the slightest hint of vibrations, the Wsdcam 113dB Wireless Anti-Theft is for you.

More importantly, you’re also provided with a remote control that allows you to trigger the alarm over a specific distance from the bicycle. The alarm is powered by 3 AAA batteries whereas, the controller works on a set of 6V batteries.

Finally, I must applaud the manufacturers for adding a nice touch of waterproof casing on the alarm. All in all, I have to say that the Wsdcam 113dB Wireless is fully worth the investment.


  • This bike alarm system has an easy setup process as it attaches to your bike frame with minimum fuss
  • Boasts a portable design as it is compact and lightweight
  • Waterproof protection
  • Various sensitivity levels and settings
  • Easy to use remote control system


  • Expect to face glitches when you switch the alarm on and off
  • Charging the batteries regularly can be troublesome

4. Bibowa Disc Brake Lock with Alarm

The Bibowa Disc Brake Lock with Alarm doesn’t disappoint with its performance.

Not only does it sound off every time it recognizes a threat, but the device is also extremely durable. Anyone attempting to damage it will fail miserably as the rugged stainless steel disc locks are hardened to resist sawing, chisel attacks, and cutting.

Thankfully, the alarm system doesn’t go off fully right off the bat. It produces a few beeps to discourage the threat first. However, if the meddling persists, it rings off a 110dB sound, thereby drawing the attention of all nearby bystanders.

I also like the fact that the Bibowa Disc Brake Lock with Alarm can be used on motorbikes, scooters, and dirt bikes too.

However, at a glance, the Bibowa Disc Brake Lock with Alarm does look rather flimsy. Also, it isn´t as waterproof as the manufacturers would have you believe.


  • This bike lock has been built to stand the test of time and withstand any external damage
  • Available for purchase in a wide variety of colors
  • Works as a motorcycle alarm feature too
  • This bike lock has a loud alarm
  • Comes with free 5-ft reminder cable


  • Hasn’t been constructed of the highest-quality materials

5. Abus Bordo Alarm 6000/90 Plus Black

It would be an injustice to compile a list of the best bike alarm systems and not include the Abus Bordo Alarm 6000/90 Plus Black.

Like the Bibowa Lock, the Plus Black Alarm Bike Lock, too, doesn’t sound off in its highest capacity from the get-go. It produces an initial warning sound to caution the thief before letting loose on its vocal capacity after a repeated offense—and it goes on for 15 seconds!

Setting the 6000/90 Plus Black is also a piece of cake. You can either fasten it to a frame tube with the provided straps or use nylon ties to set it flat on the rear rack.

Granted that it may be a bit of a hassle to carry the lock around owing to its 3.2-pound weight, but if the lock has one of the highest security settings and ratings, wouldn’t it be worth the trouble?

Of course, it would’ve been much better if the Abus Bordo Alarm locks came equipped with a GPS or supported a smartphone app notification system. But, this is as good as it gets for its price range.

In a nutshell, this alarm security is a super-theft deterrent packaged in a strong chain lock.


  • This bicycle alarm only sounds off when it detects real threats
  • Easy installation feature
  • Durable enough to last a long time
  • One of the best bike locks around
  • Favorable online review


  • This lock alarm is too heavy for my liking


Imagine having your bike stolen by a thief and you not knowing where to look or having no idea when the theft took place. Isn’t that a miserable situation?

So, why would you want to place yourself under such stress? Pay a small price for a bike alarm, have it fitted to your bike, and enjoy peace of mind as never before during your cycling sessions.

Remember that it’s always better to be safe than sorry.

The bike security alarm systems I have presented you with are all excellent options in their own right. Go through their prices and features and pick one that is best suited for your lifestyle.

Personally speaking, the SmartHalo Bike Smarter works best for me. It offers GPS and navigation, night light, and phone notifications. 

Additionally, it also has fitness tracking and allows me to keep track of useful info such as distance traveled, time taken, calories burned, and average speed.
