Guide to Alarms for Bikes


    Biking can be a convenient, cost-effective way to commute to work or school. Not only does it save you money on bus or train tickets, but biking can also be good exercise and help you stay fit.

    In order to keep your investment protected when you park them in a public place or even when they are stored at home, it’s important to consider securing them with a bike alarm.

    There are many alarms available on the market. The following are some things to consider before you make your purchase.

    What is a Bike Alarm?

    A bike alarm is a device that attaches to a bicycle and provides an audible warning when someone tries to steal it. The most common bike alarms emit a loud sound when the bike is moved or can be activated by pressing a button on the handlebars. 

    Some bike alarms have sensors that trigger an alarm when they detect movement in the vicinity of the bike. Others have sensors that detect vibration from an attempted theft or even motion within a certain distance of the bike. 

    Why get a Bike Alarm?

    You know your bike is an investment if you’re an avid cyclist. You’ve spent time and money making sure it’s the perfect fit for your body and riding style, and you want to ensure that investment lasts as long as possible.

    A bike alarm is an easy way to add protection against theft and vandalism, especially if you have a more expensive or custom-built bike. If a thief wants to take off with your ride, they will need some tools—and having a bike alarm installed can make them think twice before they try anything.

    Of course, a bike alarm isn’t just about keeping thieves away! It also lets you be more aware of what’s happening while riding. If someone approaches your bike in a threatening way or acts suspiciously while near it, you’ll know immediately and will be able to take appropriate action.

    Things to Consider When Choosing a Bike Alarm


    Durability is an important thing to consider when buying a bike alarm. You want your alarm to last as long as possible and provide the best protection for your bike.

    Bike alarms are designed to be mounted on bikes and other vehicles. If your alarm stays in place for as long as possible, you’ll want to ensure that it’s made of materials that can withstand impact from bumps and falls.

    It would be best if you also considered whether or not the product will last through rain, snow, and other elements that might damage it over time. Some bike alarms come with waterproofing features or are made from materials that are made to withstand all kinds of weather.

    Sound and Volume

    Sound and volume are the most important things to consider when choosing a bike alarm. You definitely want to consider the environment you’re in when making your selection. You want your bike alarm to be loud enough to scare off potential thieves but not so loud that it hurts your ears or has nearby neighbors complaining about the noise. An alarm that is over 100 decibels should be enough.

    Battery Life

    The battery life of your bike alarm is another important consideration. There are a few different types of batteries you can use in a bike alarm, and each has its advantages and disadvantages.

    • Rechargeable Batteries: This is probably the best choice if you have time to recharge your battery. Rechargeable batteries are often more expensive than disposable ones. Still, they last longer and will save you money in the long run. They also have less impact on the environment than disposable batteries.
    • Disposable Batteries: Disposable batteries are generally easier to find in stores and cheaper than rechargeable ones. They’re great for people who want something that will work immediately without having to charge it first (or even think about charging it). However, they can be expensive if used frequently since they have less shelf life than rechargeable ones. 

    Smart Features (GPS Tracker and Device Connectivity)

    A GPS tracker will allow you to track your bike in real-time, so if it’s stolen, you can see exactly where it is. You can also use this feature to locate your bike if it’s stolen and abandoned.

    A GPS tracker can help you recover your bike more quickly and easily than other bike alarms because it gives you an exact location.

    It would be best if you also considered whether or not the device has Bluetooth connectivity. This feature allows you to pair with other devices, such as an app on your phone or smartwatch, so you can receive notifications about when someone tries to unlock your bike or if there are any problems with the alarm system.

    Types of Bike Alarms

    Disc Lock Alarm

    The Disc Lock Alarm is one of the most popular types of bike alarms and can be attached to a disc lock.

    The Disc Lock Alarm is typically installed on a bike’s frame, with the lock placed around one of the wheels. When the lock is activated, it alerts anyone in the vicinity that someone is tampering with your bike.

    The Disc Lock Alarm can be set up using an app on your smartphone, tablet, or laptop. You can choose between different modes of operation: when you’re leaving your bike unattended or when someone is tampering with it. The latter option means that if someone tries to remove the disc lock without setting off the alarm, they’ll be punished with a loud noise!

    U-Locks with Alarms

    U-locks are a common type of lock for bicycles and are designed to secure the frame and wheels together. 

    Typically, they’re made with steel and come in various sizes, depending on the size of your bike. Some locks even have additional features like built-in lights to make it easier to see the lock at night.

    The alarm is built into the lock itself—it’s not something you need to install separately like you would with other types of alarms. The idea behind this type of alarm is that it will alert someone if someone tries to steal your bike by cutting through the lock. The alarm can be loud enough to scare away potential thieves or draw attention from a passersby if they’re trying to cut through it without anyone noticing.

    This type of alarm is fairly easy to install—attach it around your U-lock. An alarm (usually about 100 decibels) sounds off when someone tries to cut through it.

    GPS Bike Alarms

    A GPS bike alarm is the market’s most advanced type of bike alarm. It uses a GPS device to track your bike. The best part is that you can access this tracking data anywhere in the world—even if you aren’t near your bike! That way, if someone steals your bike while you’re away on vacation, you can still know exactly where it is.

    The coolest thing about GPS bike alarms is how easy they are to install: attach them to your frame and pair them with an app on your phone or computer. Then set up alerts for when your bike moves outside of a certain radius (which can be as small as 5 feet), and you’re good to go!

    Bike Alarms with Shock and Motion Sensors

    A Bike Alarm with Shock and Motion Sensors is a great way to ensure your bike is safe. These alarms are usually found on the front and back of the bike frame, but they can also be placed in other places like the wheels, pedals, or gears.

    The main purpose of these alarms is to detect if someone is trying to steal your bike. They will do this by using shock sensors that are located inside the alarm box itself. When someone tries to lift your bike off the ground without taking off those sensors, it will set off an alarm that alerts you that someone is trying to steal your bike.

    Suppose you don’t have enough room for a full-size alarm box on your bike frame. In that case, smaller versions are available at most hardware stores or online retailers such as or!

    How much is a Bike Alarm System?

    The cost of a Bike Alarm System varies widely, depending on the system you’re looking for and what features you want it to have.

    If you are looking for a basic tracker that monitors your bike’s location and sends alerts when someone moves it, the prices will range from $50 to $100. If you want a more advanced system with other features like GPS tracking, live tracking via an app, or even theft detection, expect to pay between $200-$300. For example, if you wanted a full-featured alarm system with remote activation and a theft alarm that sounds when someone tries to steal your bike ($300), expect to pay $300 or more.

    Remember that these prices reflect how much it costs for one unit. If you want multiple bikes monitored or installed at once, these costs could increase significantly. This is because monitoring costs are based on individual units, and each additional bike would cost more than one unit would cost by itself.


    This article has given you some information and ideas to help you choose the best alarm for your bike. The market is saturated with different alarms, and it’s hard to know which one is right for you. But now that you’ve learned about all the options available, we hope you’ll be able to make an informed decision when choosing your next bike alarm!
