Everything You Need to Know About Bike Alarms

Mechanical

Let’s start from the description of the mechanical anti-theft devices (chains, cables, U-shaped anti-theft devices), which are the most common and economic ones.

If you are going to buy such a system, never just fix the frame to a pole because they could take away wheels and a saddle. On the contrary, never just set the wheel because you could find only the one on your arrival.

If you fix the bike to a pole too low, they can take everything away from you by simply lifting it.

Having said that, one of the safest of the mechanical anti-theft devices is the U-shaped one because it has a considerable diameter that the thief will never be able to scratch with a standard wire cutter.

Of course, it is more substantial, but it cannot be compared to the simple steel cable that everyone can cut in a few seconds: this is because the cable is almost never often enough, say 1 cm in diameter.

Since these are products that have an affordable price, the right solution is to buy them both U-lock and cable. Indeed, sometimes they are sold together so that the wheels can be tied together with the wire and the frame can be fixed to a pole with the U-shaped mechanism.

As for combination or key chains, the quality of the steel and the thickness of the links must be assessed: the most straightforward and cheapest models can be broken in in no time.

The sheath and the external coating hinder the action of the mitre saw but, in general, it must be said that there is no system that can resist the attack of a good grinder.

Alarm

Another type of burglar alarm is that with acoustic alarm. How does it work? It consists of two parts: the actual device that emits the sound and the remote control.

The device must be fixed under the seat, the remote control must instead be set to the handlebar but can be detached to always keep it with you at the bar while having coffee or queuing at the post office.

When the attacker approaches and tries to move the bike, the alarm is triggered immediately by alerting the owner or otherwise acting as a deterrent for the thief.

This sound is audible but lasts a few seconds, and it serves only as a warning. If the thief persists or decides to remove the device from the seat, the alarm sounds continuous, without stopping; the only way to disable it is from the remote control which can have a range of several tens of meters or even 100 meters.

Often these (waterproof) devices are multifunctional because they also act as a practical rear light and even a bell. Take a look below, find some such models.

Gps

For some cyclists, the best anti-theft brand is the one that makes GPS models, those that work in conjunction with a SIM and therefore with your mobile phone. By identifying a perimeter that the bike cannot pass, the owner is immediately notified when someone takes it away.

These devices have the appearance of a standard rear light which however hides the satellite device inside or can be inserted into the barrel of the bike and be completely invisible on the outside.

On the phone, the map appears with the coordinates that indicate where the bike is located with a margin of error of a few meters.

These alarms have autonomy of a few days, then they must be recharged and can also be used on motorcycles or cars, even merely to check the movements made by a person who does not necessarily have to be the thief.

The Most Advanced Models

Starting from the most common systems, the U-shaped mechanical hook is well known among bike owners because it is difficult to cut or break (with wire cutters or hacksaws).

The consistency of the diameter prevents its removal, and thanks to the particular shape you can fix the frame to the pole. If you have an even better steel cable, because in this way you can tie the wheels to the U-hook, attaching this to the mast: ideal double protection if you have to leave the bike unattended for a long time.

Another extremely advanced system is the sound system which plans to place the alarm under the seat (check the compatibility between the two elements), and this starts to sound (reaching 120 decibels) as soon as the attacker tries to take the bike away, moving it or lifting it.

The warning continues to be issued even if an attempt is made to remove the seat and can only be deactivated via the remote control which has a range of 100 meters.

But the functionality of this system does not end there: in fact, it also acts as a bell and rear light. Therefore it proves even more useful by protecting your safety when you are pedalling. You can charge it via USB, and you won’t have to be afraid to leave it exposed to water, because it’s waterproof.

Gps Anti-Theft

The system equipped with a GPS antenna is even more advanced than those described so far. In combination with a SIM card, the burglar alarm warns the owner as soon as the bike exceeds the preset range of meters and the map is sent to him, useful for reaching the thief and recovering the motorcycle.

From the outside the alarm looks like a traditional position light but can also be inserted inside the barrel of the bike, being invisible to foreign eyes: given its size, it is incredibly versatile, and you can also use it on the machine or provide it to a person as support in any awkward moments.

Useful Tips for Cyclists

Regardless of the protection system, always tie your bike to a rack, a pole or a tree, to make theft more difficult and complicated. Don’t just match the saddle or the wheel, as these are easily detachable components: by removing the motor or the seat, and the attacker can take the rest of the frame home.

Tie the pole or tree to several elements of the bike, to discourage the thief who immediately realizes the complexity of the situation.

If you don’t want to resort to technology and prefer to use a traditional chain, choose at least the one with a square section. Finally, we conclude this guide by reminding you that no method is infallible, but that having targeted measures is an excellent deterrent.
