Why You Want to Use an Alarm

Deciding to have an alarm shouldn't be difficult. Having one provides peace of mind, and in a society where it seems that anything not nailed down (and then some) is fair game, it is only right to protect your assets. This is especially true if you have a large investment in your bike, and you have every reason to go through your day without worrying about losing your means of transportation.

Whether your bike alarm is used with a lock or is a stand-alone, it is a surprising deterrent to anyone tampering with your property. They make noise, and some light up and are remotely accessible. Just seeing a lock can deter many thieves; adding an alarm provides even more security.

The History of Bike Security

Bike locks have been around for well over 100 years, with early designs popping up across Europe and later the United States to deter quick theft.

With advances in technology and material creation, locks have become more durable, lightweight, and even stronger at deterring theft.

This technology has also allowed the inclusion of alarm systems. Many locks use a built-in alarm, and it's easy to pair the lock and alarm together. However, there have been some more advances in the last few years that provide Bluetooth operation, smartphone syncing, and even tracking for stolen bikes for rapid recovery.

How Bike Alarms Work

Bike alarms are generally small devices that are generally easy to conceal on the frame or under the seat. They pick up on vibration and movement, and they emit a loud sound when activated. Some also include lights or other technological advances such as Bluetooth capabilities and even tracking.

How to Choose the Best Bike Alarm for You

Not all bike alarms are made the same, and many are simple deterrents for thieves looking for a fast getaway. Some are less expensive and excellent for low-crime areas.

Other choices can run rather high cost-wise but are made from durable, theft deterrent materials, have multiple settings, and do more than just work as an alarm.

If you have to leave your bike unsupervised, or you know that bike theft is common in your area, alarms are a worthwhile investment. Adding an alarm makes your bike that much safer.

You also have to consider what fits your bike and where you can place your alarm, although many do come with easy attachment solutions. Most alarms, unless built into the lock, are very lightweight and hardly noticeable.

Lastly, consider preference. If you like a certain style preference, but wish it was more durable, do some homework and see if you cannot find a good compromise as there are many different products to choose from.
