Wsdcam 113dB Bike Alarm Wireless Vibration Motion Sensor Waterproof Motorcycle Alarm with Remote

Works great and the sensitivity levels are legit. It's loud and works as described.

Great alarm. Just takes a few minutes to figure it all out but it's easy enough once you get the hand of it. I think the remote needs a little work as it is plastic and the key ring attachment part is thin and I can see breaking as other have stated. Alarm is very annoying which is what you want to go with your multi-phased lock approach. This should not be relied upon alone. You bike kit should carry spare batteries and you should test this before every trip just to make sure batteries are good. Small enough to easily conceal.

I came to this purchase one week too late. Thieves nicked my seat, lights, and a bike rack I loved. I lock my bike in my basement in a NYC brownstone. I live in Harlem. Lot of bike thieves and crackheads find ways into buildings or residents themselves steal your stuff. If I would have had this baby. No way. The whole building would hear. No joke. The walls are cement, and the high pitch sound resonates at a deafening tone. Even if no one were around, the would be thief would actually get ear damage taking the time to work out my locks. I myself hurt my ears just setting up the device. Wow. Ive set it to the highest sensitivity. If a spider farts it goes off. Love it. Oddly, now my concern is hurting someone's ears or waking the building up if it goes off. I'm on the 5th floor. And yes, I hear it. I bought a bike stand to go with it. I couldn't have any accidental tips or falls just from placing it on the wall, I used to do that and the bike would often shift. So, I feel I have a really good set up now. Stable. So any movement of the bike is 99% intentional. Lets assume a ridiculous scenario: I turn on the alarm, but I only place it on my seat. No ties or stick tape. Can the thief still get to my bike? Well, sure. But not before he sets off the alarm and I hear it. Plus, then what.... the alarm is going off, where's he going to put it? Needs a bucket of water to place it in. So... there. The only way I see to defeat this device is with another key. A hacked signal or some other Jason Bourne shit. You need a bucket of water. Owner has to arm the alarm, but not attach it to bike. Then thief has bucket of water ready to go, gentle moves alarm into bucket of water. Have I thought this out too much? My point. The alarm will trip even if the thief tries to remove the device, even if the thief knows its there ahead of time. Said thieves would have to sound proof the area some how. Its that loud. Especially in an enclosed area. Ive only had it for a couple days now..... So I dont have time on my side as far as a long run record. We'll see. I feel like Ive spent the best $17 on protection for my $1000 plus bike. Even if this alarm broke every 6 months. I would still replace it with another. Its that cost effective. I cannot speak for longevity.... so thats an if. I hope all the hardware and software holds up. So far so good. I sleep better at night. And besides. Its pretty BOSS. Walking up to my bike and hitting an arm or disarm key. Its fun. Pros: Solid simple construction Cost effective Easy install Varied sensitivity and volume.... It works! LOUD! Cons: Im unsure of battery life, and I dont know if it warns of low battery. Id assume alarm is best for places where your bike isn't getting jostled by other people sharing a bike rack or mount. Id hate to F with the innocent, with a sonic blast, cause a heart attack. Sensitivity settings may assist here? Size? Its a little on the big side. It ruins a 'clean look' on a sleek bike. Hiding it could be an issue unless you had a bike rack(underneath). I wouldn't want it inside anything. I'm thinking of buying another just for the bike rack alone.... and maybe one more to put on the milk in the fridge. To give my roommates late night milk cravings a freak. Ill update in a few. And I'll do a pic of final set up. Waiting on a few things. Cheers, OccamsPhazer

I bought this two and a half years ago, and it worked pretty well. The default batteries sucked, but I got some duracell batteries and those last a little over a year. Today they finally went low charge while I was out and unfortunately, two out of the three batteries had good charge left causing just enough of a voltage to allow it to beep the entire way home while not responding to the remote anymore. xD However, I like how loud it is, it functioned just fine in -10F or less weather, up to 100F weather. I've been in rain and had water splash up against the underside. It was right near my tire so it probably took all the mud and splash back that didn't get caught by the mud guard. This thing was so loud I had to warn people nearby when I was disarming it or arming it as it'd scare the crap out of people. Perhaps it could use a different volume of arm and disarm compared to its alarm. The springs inside the case corroded so thats why I have to buy a new one. I was about to replace the batteries again when I noticed. Perhaps it needs to be sealed a little better in the future if water can somehow still get in to corrode the components. However this is an older model so that may be fixed on the newer models. I'll be trying the newer version I found thats USB charge-able now.

It’s worth the price and easy to install.

If someone really wants to steal your bike, they're gonna get it, but this alarm (and a couple VERY GOOD locks) can improve your chances of hanging onto your fine ride under most circumstances. I've purchased two of these alarms, one for my 'Lectric One eBike and one for my cargo eBike. Both work as advertised and produce a nice, loud alarm if someone doesn't learn from the warning "chirp" that sounds whenever the bike is jostled. I like that I can set it for different alarm sounds and volume levels, though I'm not sure why anyone would want less than the maximum noise setting, considering it's stated purpose. On the downside: It's not terribly well-made. The little plastic disc that covers the speaker fell off on day two. The unit still works, but I'm guessing eventually that exposed speaker is going to get wet or brittle or dirty or whatever else the little plastic disc was supposed to prevent. The remote control also seems a tiny bit on the flimsy side, though it works very well and the range is more than acceptable. For the money, this unit is a pretty good deal. And the peace of mind it gives me is worth a few bucks.

Got it 2 months ago, use it for my everyday ebike commute. Product is easy to use, loud enough to scare people when a light bump triggers it.( To adjust sensitivity and volume, search YouTube, there's plenty of tutorials). The black colour and size makes it pretty easy to hide, especially with zipties. It fits pretty much anywhere, as it is about the size of a stapler or smtg.

Not as sensitive as I would like. I used the max sensor setting but you need a lot of movement for it to go off. The instructions are not that great either. Just a deterrent for my car. Loud enough though. I just Velcro underneath my bumper whe I need it.

Puedo graduar el nivel de sensibilidad para que no salte con el ruido, me ha encantado!!!

Un antifurto elementare ma perfettamente efficace e semplice da utilizzare, ottimo per bici. Ampiamente consigliato

Ordered this for a European bike trip where I wanted something cheap and cheerful to just give me peace of mind when I park my motorcycle overnight, coffee stop etc. Ok so the English translation isn’t the best and wouldn’t get an A* in a GCSE but you get the idea easy enough and it works a treat. Click button to arm and click button to disarm. Stick it on with the supplied stick pads and cable ties and if the bike is jogged or moved the thing lets rip with a shrill ear piercing scream that will keep most thieves at bay. If they want to steal your bike they’ll get it anyway even with the best alarm kit. It was £17, it does the job and will do fine.

So far so good! Arrived very quickly as advertised and was fitted within minutes. Nice and sensitive (my friend went to sit on my R1 and it immediately 'warned him' with a loud beep. Gives a bit of a sense of safety when parked outside my house at night. Good purchase and excellent value for money.

On opening up the alarm to try out the batteries and the device, I had a concern. The screw seemed really cheap, as did the screw driver. I was worried about stripping the screw itself or the plastic. But I used my own Phillips screw driver and gently got that screw out to proceed to the next step of opening up the alarm box. They give you a plastic device that looks like a guitar pick and that was useless in trying to open up the alarm box. I got two slot head screw drivers and used those to wedge away at the tightly sealed plastic. I ended up chipping the plastic a bit opening up the two halves. Next, was installing the three triple A batteries. They looked real cheap, so I threw those away and used high quality batteries I purchased separately. The batteries installed securely. Everything looked intact inside, so I put the alarm box together again to try it out. Next, was trying to read the very, very small print instructions with my big magnifying glass. I gave up on that and went to You Tube to find instructions there and I did. So I slowly went through setting up the remote control’s three buttons. That went well and discovered, an excellent bike horn. The seven different high pitched alarm to chose from in pitch and the three different types of noise was a perfect deterrent noise. I don’t get my new e-bike until May and can’t install/ try it out until then. But I’ll install the alarm with the tie wraps and the two-sided stickers provided. The location will be under my seat in the posterior direction to keep it drier. Once you activate your alarm, by the remote button. The first disturbance (dependent on sensitivity setting you chose. I suggest the 4th level) your alarm sounds a warning short beep. On the SECOND disturbance of your bike, then the continued alarming begins. The noise definitely will attract onlookers and annoy your bike thief. This remote is effective for 60 feet away. My Apple Air Tag will be located under the bike seat, just inches away from this alarm - under black Gorilla Tape. The remote control will be located by my right thumb on the handle bar, because of that cool sounding horn. I use my plastic rescue whistle as well and a flicker bell alarm to warn people ahead, I am coming behind them. Then I announce verbally, “passing to your left” and carefully pass other hikers on the bike pathways. The color black blends into my seat and bike rack color and the looks of the alarm appears esthetically good for my bike. Overall, I am confident the alarm/ horn will endure a long time and will do its job to SCARE AWAY THE THIEF or at least slow down the bike thief. Even though the bike horn will be located under my bike seat, I am again confident pedestrians and other bikers will hear this horn. So good price and apparently good, effective bike alarm!!
