How Do Bicycle Alarm Locks Work?

Bike locks with alarm are designed to pick up motions and vibrations and send out a warning sound in response. The alarm goes off for a specific duration or until the trigger (motion or vibration) seizes.

Some even light up, and if they are wirelessly paired with your mobile phone, you get an instant alert. That means you don’t have to be physically present to monitor the bike’s safety.

Mark you; these locks can also work without the alarm. So, you don’t have to activate the alarm all the time.

There are also a few others with GPS trackers. Such options not only deter thieves but can help you track your bike if it gets lost.

Buying Guide for the Best Bicycle Alarm Lock

Here are the essential buying considerations:

  • Strength and Durability

This does not just apply to alarm locks but all bicycle locks in general. You need an alarm lock that is strong in build to serve you longer.

The lock should resist vandalism, for starters. That’s more important when you forget to activate the alarm or when it fails to go off for whatever reason.

In the long run, buying a durable alarm lock saves you money.

  • Sound Quality

Remember, you are buying a bike lock with alarm for its disturbing noise.  So, the sound must be loud enough to deter thieves and even alert the public.

Thieves don’t like to draw attention, and so when they hear the alarm go off, they are likely to run away.

  • Battery Power

While some alarm locks come with disposable batteries, it’s smarter to go for rechargeable ones. With rechargeable batteries, you don’t have to worry about them running down.

More importantly, you don’t have to waste money on batteries. You save cash in the long-run.

  • Ease of Use

You need a lock that you can use to secure your bike quickly. Don’t waste time trying to set up the alarm lock.

And when it comes to unlocking the bicycle, the process should be equally fast. Of course, it should be a one-man’s job.

More Considerations

  • Weatherproofing

Even if you don’t plan to lock your bicycle outdoors, the chances are that you may have to contend with bad weather sometimes. That’s why you need an anti-theft alarm for bikes that can resist it all.

You wouldn’t want the bad weather, especially precipitation, to damage your alarm lock. So, do your homework to find a weatherproof option.

  • Weight and Size

You’ll have to carry your bike’s alarm lock. For that reason, it has to be lightweight to encourage portability.

In the same wave, its size should allow you to carry it with ease. When looking at the size, ensure the lock has a sizeable cable if you opt for the cable-type.

  • Special Features

Lastly, watch out for the added features that come with bicycle alarms. For example, if the lock is keyless and allows you to engage and disengage it using code combinations, consider that.

Also, if it allows remote-controlling using a smartphone app or a remote control device, consider that as well.

The other thing you should consider is GPS tracking, which allows you to locate a stolen bike.
