Best Motorcycle Alarm Systems

The YOHOOLYO Motorcycle Alarm Padlock is constructed entirely from metal, making the padlock tough as nails and twice as durable. The aluminum alloy disc is resistant against rust and all but immune to corrosion, so rainy days will not do any damage to the lock. Though the tough lock does not look sophisticated at all, there's some intricate circuitry inside this device, not unlike the motion sensor that will be able to detect people approaching the bike with a five-second delay.

These things do not have to be sophisticated though. They have just to be secure, reliable, and practical. There's nothing sophisticated about the 7-mm lock pin but, with the increased length, you can rotate the pin 360 degrees to fix this disc brake lock into any position.

The device works using six LR44 batteries and is supplied with 12 batteries, so you won't have to purchase replacement batteries anytime soon. On the not-so-bright side, the battery compartment is quite small, meaning that changing the batteries is more tedious than one would expect. Aside from the batteries, the device comes with two keys, which's great since you don't even need one to lock the padlock, so you'll always have that spare key. In other words, the YOHOOLYO Motorcycle Alarm Padlock will only be making the thieves uncomfortable, with its tough build and a 110-decibel alarm.

Setting unnecessary introductions aside, with its sensitive and responsive sensors able to detect not only shock but also motion, the disc lock from Tchipie will be able to keep any motorcycle safe and protected. The more than audible (110 decibels) alarm system will usually scare them away even before they're able to attempt tampering with the lock.

Despite that, the lock presents no challenges to the owners, with its one-press operation locking the device without using keys, going into the alarm mode right away, with the "beep" sound telling you that the alarm's working as intended. Some find the lock too sensitive as even the wind can set it off sometimes but that's the sacrifice we're willing to make, better to be safe than sorry and all that. Even approaching the bike, before the vibrational motion sensors are able to react, the device's bright red finish and the orange reminder will usually work as this surprisingly effective visual deterrent that makes most thieves think twice.

Construction-wise, the aluminum alloy body is pretty rugged, sealed against moisture, dust, and dirt to protect the lock not only against the thieves but also the elements.

Bottom line, the Tchipie Alarm Disc Lock will make sure thieves do not even think about stealing your bike but, when they do, the locks make their chances pretty slim.

The Dowco Guardian 26038-00 keeps things simple, as one would argue all motorcycle locks should. First, the lock is quite small, measuring only 7.8 x 5.3 x 2.2 inches and 3.2 ounces, so you can shove this one inside any backpack and even sometimes pockets. The device tethers to bikes within seconds and usually takes 2-3 minutes to install, hence the whole "keeping things simple" part above. You can clip this one to forks and wheels alike.

Even then, do not confuse simple with lacking because this lock is lacking nothing. It is certainly not lacking alarm loudness, able to reach 130 decibels, which's even louder than police and ambulance sirens. To stop the alarm, you remove the detached pin that's on the lanyard, nothing complicated but also not something that thieves will be able to figure out fast enough with the alarm blasting before them. The construction is anything but lacking too, with the weatherproof housing making the device protected against the elements.

You need but one 9-volt battery to sustain the device but the battery's not supplied with the lock, so you'll have to purchase it separately. Aside from that, the takeaway here is that the Dowco Guardian 26038-00 is affordable and simple yet more effective than most complicated locks.

The Wsdcam Wireless Anti-Theft Alarm is different from the locks we've reviewed before. For starters, the device can be operated via a remote and is able to pair up with 8 remotes. Using this remote, you can choose between seven sensitivity levels, so you'll be able to decide what triggers the alarm, from the most gentle nudge to push to beat/kick, which's great since you can reduce false alarms.

We've seen motorcycle security systems with these settings before but what we haven't seen, at least not as much, is the vehicle search function that makes sounds when you press the ringtone key so that you're able to easily find the right vehicle. You can even choose between six different ringtones, a little too much from where we're standing but hey, who are we to judge.

We're certainly not judging the SOS feature that starts blasting an alarm when the cyclist falls down (meaning that the vehicle is tilted 45 degrees) as thing feature can even save lives. We're not judging the remote's <66-feet range, letting you manage the alarm system from respectable distances. We're somewhat judging the sensitivity settings that we've mentioned above since they're pretty hard to adjust but that's what usually comes with extra options and that's the price that we're more than willing to pay to make the alarm system not only secure but also less aggravating.

The Onvian Wireless Anti-Theft Bike Alarm is cheap, which's pretty odd since we're not sure why the alarm costs less than 15 bucks considering everything that it is able to do. Sure, the instructions are confusing, so it might take you some time to figure the device's many settings out but that's not the biggest issue you can usually find with most motorcycle alarm systems. The alarm's loud enough, able to go as high as 113 decibels, basically matching police sirens. Plus, you can adjust the sensitivity, with 7 available levels allowing you to all but eliminate false alarms. Besides, the device will even let you choose between 6 ringtones, so you'll be able to make the alarm relatively unique but also easily identifiable from standard tunes.

When the bike tilts above 45 degrees, the alarm will start blasting an SOS noise alert, notifying people nearby that you're probably hurt. Of course, you can always turn this feature off since it is not hard to imagine this thing blasting when the accident is nonexistent.

Add to everything we've revealed before the low battery indicator that will make sure you're not caught off-guard with dead batteries and the vehicle finder feature that you can press to make the device start emitting sounds to locate your motorcycle between countless bikes and, again, the price makes no sense but we're not complaining here, only pointing out that you'll probably more than like the product's price-performance disposition.
