We live in an unfair world where many people take advantage of other people's goods. So alarms in general are an investment that we would never want to make, but are becoming more and more necessary.

Motorbikes are also subject to many thefts and it is best to protect them with a good alarm. We have prepared an article that will take you step by step to make the best buying decision. By the end you will be ready to protect your bike from the hands of criminals.


  • A motorbike alarm is a device that provides protection against theft by sounding a siren if it detects suspicious movement. It helps you feel confident that your bike is safe no matter where you park it.
  • There are lockable and non-lockable alarms. Lockable alarms have the advantage that in addition to sounding if there is danger, they immobilise the bike for added protection. On the other hand, those that do not include a padlock can be controlled remotely, without the need for a key.
  • In order to make the best purchase decision, it is necessary to consider some factors such as the materials of the alarm, the power supply or the intensity of the siren. We will discuss these criteria in more detail below.

What is a motorbike alarm and what are its advantages?

A motorbike alarm is a device that provides theft protection for your vehicle, and works in a similar way to a car alarm. If any kind of movement is detected, a loud alarm is triggered to scare off the alleged offender.

In addition, many models also incorporate a mechanism that inhibits wheel movement for added security. This makes it more difficult for the motorbike to be moved from where it is parked, even if it is switched on.

There are also many products that function as a GPS tracker in case everything else goes wrong. This way you can at least know in real time where your bike is so you can notify the authorities and come to the rescue.

  • Provide security for your bike
  • Easy to install
  • Relatively inexpensive investment
  • Give peace of mind
  • Can be fitted to the electrical system
  • Can be activated accidentally
  • Often alarms do not prevent theft
  • If battery operated they require constant changing
  • Only work when your bike is parked

Motorbike alarm with or without a lock - what should you look out for?

We can divide the different models of motorbike alarms into two categories: with and without a lock. Both offer interesting benefits, but we want you to be clear about the differences so that you can consider which type of alarm is best for you.

Padlockable alarm. This type of alarm can be in the form of a conventional padlock or can be fitted to the disc brake. In addition to emitting a loud alarm, the main advantage of this feature is that it helps to immobilise the motorbike. However, they are usually powered by disposable batteries.

Padlockless alarm. Padlockless alarms have the main advantage that they can be connected to your bike's electrical system. In addition, some models can be controlled remotely, as if they were cars. However, their only function is to sound the alarm, but they do not prevent the bike from moving.

Immobilises the bike Yes No

Activation mode Key Key or chip

Are there alarms with apps?

Technology these days has allowed alarms to evolve to the point where they can be controlled from an app. These types of motorbike alarms let you know in real time if there is any suspicious activity near your bike. You simply place the device under the seat and install the provider's app.

The disadvantage of these alarms is that they are still quite expensive. Also, for them to work properly you need to be within range, which is usually less than a kilometre. Another disadvantage to consider is that these alarms also do not immobilise your motorbike and use batteries.

Buying criteria: factors that allow you to compare and rate different models of motorbike alarms

In this section we offer you some criteria that you should consider before deciding to buy your motorbike alarm. We are sure that you will find them useful and that once you have reviewed them you will make the best purchasing decision.

  • Sensitivity
  • Resistance
  • Power supply
  • Alarm intensity


This criterion is very important because although we want a sensitive alarm, an extremely sensitive alarm can be counterproductive. It is of no use to us if it goes off at the slightest provocation, because when it is really being stolen, we will not pay any attention to it.

The best way to find out if the model you are looking at is too sensitive is to read the product reviews. There you will corroborate the experiences of previous buyers and you will know how sensitive the alarm is. We recommend that you choose one that is not so sensitive to avoid false alarms and make sure you act in time when it goes off.


It is important that you take into account a few things to ensure that your motorbike alarm will withstand the rough use it will be subjected to. It won't do you much good to have an alarm that you have to continually replace. You need to have complete confidence in your security system.

Waterproof. It sounds obvious, but many motorbike alarms neglect this aspect because they assume that the alarm will be hidden. But motorbikes are vehicles that are always in contact with the elements, so we recommend that you make sure the manufacturer guarantees water and corrosion resistance.

Materials. You should pay attention to the quality of the materials, especially if it is an alarm with a padlock. The lock must be resistant to cutting with saws, pliers or drills. We recommend that you look for stainless steel or zinc alloy to ensure the quality of the padlock.

Circuitry. Since your alarm will consist of an electrical circuit and a battery, it is essential that water cannot get into it. In addition, it must be constructed of quality materials. We recommend that your alarm has a system for recognising the condition of the circuit and battery, either with a light or sound indicator.

Power source

As mentioned above, motorbike alarms can be powered by batteries or directly from the electrical circuit. Both offer some advantages, but also disadvantages. Consider carefully what you need to get the most out of your investment.

Batteries. Battery-powered alarms give you the ability to easily install and uninstall your alarm. You will need to keep an eye on the life of the batteries and replace them as soon as they start to fail, but you can take them everywhere. We recommend this power source if you are looking for a lockable alarm.

Electrical circuit. This power supply allows the alarm to be permanently fitted to your bike. Some even allow you to control it remotely via a controller. We recommend you purchase this way of connecting your alarm if you are not looking for a lock and prefer to control it without having to use a key.

Alarm intensity

The sound produced by your alarm is measured in a unit called a decibel (dB). The decibels at which your alarm sounds will depend on the manufacturer's criteria and can be found in the product description. In general, motorbike alarms range from 100 dB to 130 dB.

It is always a good idea to look for loud alarms to attract attention, but be aware that they can be set off accidentally. If this happens while you are mounting or dismounting it, it can be dangerous, as your ears will be very close. We recommend that you look for an alarm that gradually increases in volume for your safety.
