    Features To Consider When Choosing A Bike Alarm

    A bike alarm is a one-time investment. While bike alarms come in different models, they differ in many ways; therefore, you need to choose wisely. There are certain features that a reliable bike alarm should have. Some may not seem important but are the most significant features to look for.

    Before purchasing the best bike alarm, here are some factors to consider:

    Does Your Bike Need An Alarm?

    Almost daily, we hear stories of people’s phones getting snatched or individuals getting mugged in the streets. With a valuable asset as a bike, you are bound to ensuring it’s safe and secure. You might have already fixed the alarm in your GPS tracker or lock for long, and you’re wondering if you still need it. 

    You never know when you will walk to your garage and find your bike missing from its usual parking spot. This is why it is necessary to have the alarm on your bike despite where you pack it.

    Integrated With Bike Lock

    If you intend to get an ordinary bike alarm, or your bike already has a lock, then you can pick one that’s not integrated with the bike lock. However, if you need a full security system, an alarm with its lock is necessary.  

    Cost

    Bike alarms come in a wide variety of models. Every model has unique features hence different pricing. Before purchasing, you need to budget and check out the models that fall within your range. 

    Since your ride’s alarm is not something you’ll purchase frequently, get good quality even if it means parting with some extra dollars. Thieves might destroy low-quality alarms.

    Noise & Light Warning

    Your bike’s alarm volume is another critical factor to consider. In case of impending danger, the alarm will make noise to alert you or bystanders.

    One hundred decibels should be enough. Depending on where you park your ride, you can get a louder one, if it’s a fair distance.

    Also, go for a light warning alarm that’s consistent with the noise. This will catch your attention in case you’re in a noisy area and can spot your bike.

    Technological Advances

    With rapidly advancing technology, bike alarms haven’t been left behind.  Most of them have a shock sensor that activates immediately any movement is detected. Besides, they have Bluetooth and emergency SMS texting to alert you of any threat as well as GPS trackers that can help you locate your bike in case of theft.
