Bicycle lock with alarm: 6 models in comparison

Almost 265,000 bicycles changed hands in Germany in 2023. However, not on a legal way. The number of bike thefts dropped compared to the year before, according to Statista-but only minimal. The victims should hardly comfort that the figures from the 2010s have not yet been reached. The statistics do not include whether the long fingers cracked the locks or the wheel was carelessly turned off and was also easy prey. Basically, it doesn’t matter either. If you take sight of your wheel – even if only for a few minutes – you should secure it with a bicycle lock.

The motto has always been: the thicker the steel, the safer. Because the larger the tool is that the thieves need, the more noticeable the action is. But the more robust chain or temple, the heavier and unwieldy the locks are usually. And yet: there is no ultimate security that a well -known manufacturer proclaims for its most expensive products. Or? Bicycle locks with alarm function have been on the rise for several years. Ultimately, the manufacturers copy what has been around for a long time (but is rarely used). There is already a spiral lock with alarm for less than 30 euros. If you want to have a bracket or folding lock with “Piiep”, you should plan between 50 and 120 euros.

A bicycle lock with an alarm is supposed to scare the alleged thief and draw passers -by to his project. The alarm is triggered as soon as someone is working on the castle without the right key. While only a short warning signal sounds with small vibrations or a ball that flies against the bike, the lock reacts when handling for a long time or cutting the lock with an alarm signal up to 100 dB. This corresponds approximately to the noise of a chainsaw or a compressed air hammer and should flee every long finger.

Important: The loudest alarm is useless when the batteries of the castle are empty. Therefore, check the state of charge regularly. After connecting the bike, some manufacturers sound a short acoustic signal that indicates that the alarm is sharp. If this signal is missing, the batteries should be replaced.

With the in -house security level ten (a maximum of 15), the Abus Bordo 6000 is already one of the most stable and safest bicycle locks even without an alarm. In addition to the ironing locks, folding locks such as the Bordo 6000 for bicycle thieves are too lengthy undertaking. To do this, you have to calculate an additional weight of around 1.3 kilograms when driving. That brings that With alarm function in the 90-centimeter version on the scales. If you want to be on the safe side, you can which only costs a few euros. With a 20-second long and 100 dB loud warning tone, the Abus lock Langfingern is supposed to screw up the coup. The technology behind it describes Abus as a 3D position Detection. The should recognize suspicious vibrations.

The heavyweight in this mini comparison is a steel chain lock from Nean. The almost 1500 grams of steel are covered with a robust, UV-resistant plastic fabric. Here, too, the integrated alarm reacts for vibrations at the lock or locking head. The 95 dB loud warning tone should quickly flee to petty criminals. With a length of 90 centimeters that is A little shorter than other locks with alarm. But the flexible square chain members enable the lock to also secure mopeds or motorcycles. The price is currently unbeatable (as of May 2023).

Spiral locks are particularly popular when connecting children’s bicycles. They are comparatively light and very flexible. Most of the little racing drivers: Inside, there are no problems on and to complete their bike again. Disadvantage of the Flexi locks: Compared to ironing and folding locks, the security level is rather low. It is all the more sensible for the practical locks an additional acoustic alarm. That also has that . This is 120 centimeters long and equipped with a motion detector at one end. Which in turn is fed by a 9V block battery. A 105 dB loud alarm signal should be enough to prevent thieves from stealing the secure bike. With 560 grams, this bicycle lock with alarm is one of the lighter in this small comparison.

We continue with a smart frame lock of the Brandenburg start-up Haveltec. This is assembled, like that of frame locks, is mounted on the pre-drilling of the seating struts behind the seat or saddle tube. Important: The tires may be a maximum of 64 millimeters wide, otherwise this can do not close.

A smartphone app takes care of everything else. They are available for Android as well as iOS. The lock is closed and unlocked via the app. As soon as you approach your bike with your smartphone in your pocket, the I LOCK IT+ opens automatically. If the wheel is accidentally bumped into in its absence or crazy by another cyclist when connecting his bike, the app reports with a three -time warning tone. In the event of further vibrations, an 110 dB loud alarm Langfinger should flee. Smart: The wheel and the castle can be shared with friends and the family via app. For emergencies, a color code can be set with which the lock can be unlocked manually.

Exciting: If you want to chains your bike on the bicycle racks, you can do this with a chain cable that is available as an accessories for the i Lock IT+ and can be connected to the frame lock. As an alternative to opening via smartphone, Haveltec offers a hand transmitter for the keychain. Both tools are extras that are not included.

After all, the Security Level eight classes that in the in -house ranking. Technically, the 1100 gram castle can keep up with the Bordo 6000KA in the folding version. The 3D position Detection System registers unusual shocks and movements and, with a warning signal at least 100 dB, raises an alarm for 15 seconds. After that, this alarm switches on itself sharply again. The round bar made of hardened steel has a diameter of twelve millimeters. As with almost all ABUS locks, the right bracket for the bike is also included.

Only 460 grams are dragged around when you has on board. In this rating, the cable lock is at the forefront. And it can also keep up with the folding and ironing variants when it comes to volume. According to the manufacturer, long fingers who are working on it get a loud and deterrent whispering on the ear. The alarm reacts to bumps or movements and as soon as the spiralized cable is cut. For spiral locks, the supplied bracket, which can be mounted on the frame, is rather rare.
