Types Of Bicycle Alarm Systems

There are external and internal bike alarms.

Some of these alarms can be linked to a smartphone application to receive notifications directly to your phone.

The initial cost of getting an external bike alarm is lower than buying a bike lock with an alarm.

2. External Bike Alarms

This variant comprises mounting a bike alarm and bike lock separately. The ideal places to put one are under the saddle, under the porter, or on the handlebar.

It usually has a remote control or an additional transmitter that facilitates alarm operation and message issuance. You will need to carry it around so that you can react in case anything happens.

Does A Bicycle Alarm Work?- More Perspective.

It makes sense to find out how a bike alarm works when exploring the question, “do bike alarms work?” so how does it work?

A bicycle alarm works by picking up movements and vibrations through the sensors, generating a warning sound, and flashing the lights. If the disturbance persists, the alarm proceeds to the second phase by sounding a continuous loud sound while the lights continue flashing.

If there is no threat to your bicycle, you can turn off the alarm using the remote, through the app, fingerprint, or you can open the lock and enter the code, depending on your bike alarm model. It will also stop when the vibrations stop.

The sound of the alarm will alert and other individuals closeby that your bicycle is at risk of being stolen. Besides helping you react in time to stop the theft, the blaring sound brings attention to the bike and the thief, which is the last thing they need when trying to pull a robbery.

If the perpetrator succeeds in stealing your bike, you can track it using GPS. However, this is only possible if your bicycle alarm is GPS-enabled.

Some bicycle alarms are equipped with advanced features, such as lights and tracking, and Bluetooth capabilities. An excellent example is the G Keni Bike Tail Light Rechargeable, Anti-Theft Alarm, that has safety taillights.
G Keni also has a waterproof design, an electric horn, USB charging, and a theft-deterrent alarm that has remote deactivation and activation. You can find your bicycle through sound or light with the remote control covering up to 164 feet (50m).

Do Bike Alarms Deter Thieves?

Bike alarms deter thieves by sounding a loud, annoying, continuous sound that is a nuisance to the perpetrator. In addition, the sound alerts the owner and bystanders that someone is trying to vandalize or steal your bike, prompting an immediate reaction.

A bike alarm is an excellent deterrent to anybody trying to tamper or steal your bicycle or its accessories, whether the alarm is a stand-alone gear or integrated with a lock. They produce a loud noise, and some models light up to notify you of any unwanted movement and activity.

A bicycle lock alone is enough to discourage many bike thieves, so introducing a bicycle alarm raises your bike’s security levels when you park it.

Is A Bike Alarm Worth It?

A bike alarm is worth it because it helps you keep your bike secure by warding off thieves and vandals. Considering that a bicycle is a huge investment, deciding to get a bike alarm shouldn’t be tough, especially since it only costs a few bucks yet is pretty effective.

How To Choose The Best Bike Alarm

Bike alarms are not identical, so you need to examine your options critically to make sure you buy high-quality gear. To achieve that, you will need to consider volume and sound, durability, battery life, and other extra features.

1. Sound And Volume

The sound generated by the alarm is a feature you must account for as it needs to be loud enough to be heard clearly and distinct for you to recognize it.

Go for a bike alarm that produces at least 100 decibels, and don’t be scared to go much higher, particularly if you tend to park your bicycle at a considerable distance from you.

The sound needs to be noticeable; hence choose a high-pitched consistent alarm instead of one that beeps a couple of times then goes back to standby mode.

2. Durability

The best bike alarm doesn’t break easily. On the contrary, it can withstand the forces of harsh elements, such as rain, gravel, and rain.

Thieves and vandals will not easily destroy a long-lasting bike alarm, so it’s better to spend more on a durable alarm instead of a cheaper one that will break before it even sounds the alarm.

3. Battery

Since bicycles don’t generate electricity, your bike alarms will need a battery to run, and it should be long-lasting to ensure it doesn’t stop working when you require the protection most.

Some bike alarms can run on a single charge for weeks, while others will last even for a whole month under the right conditions. Long battery life means you won’t spend a lot of time charging your bike alarm.

4. Additional Features

The extra features you find in a bike alarm add more functionality to it. These features include electronic bells, GPS trackers, and emergency texting.

The features in bike alarms differ, so you need to figure out what you need an alarm to offer before buying. If a bike alarm is all you need, then the extra features aren’t essential.

However, if your budget allows and you’d rather have a complete package, then go for the additional features even if you won’t use them immediately, as they might be useful in the future.


1. Are Bicycle Alarms Any Good?

Bicycle alarms are quite good because they strengthen your bike’s safety by scaring away thieves through the blaring sound. Also, an alarm with GPS tracking makes it possible to trace your bicycle’s location if it’s stolen.
