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

There are already a lot of photos and videos of this product so I will not beat a dead horse. I can see where there could be some problems with placement of the alarm. If you were to put it in a place that gets more vibration or unmitigated shocks, I could see it being damaged. However, if you think critically about where you place the it, you should not have any problems. I installed this on my ebike and it has been working great. Too good, sometimes, like when I forget to turn it off before unlocking it from the bike rack or going to jump on it to take off from behind my house. Everything works very well though I have not gone in to change settings at all because the first time I pressed any button it was the emergency button, in my bedroom, and it was earsplitting. Seriously the neighbor upstairs probably thought... I don't know what I would have thought but it would have woke up the whole house and my ears were ringing. I have seen the issues some people have with the fob. Maybe they will eventually make one a little stronger so that you can put it on your keys, but for my purposes, I did not even really want this on my key ring and I had a better solution just sitting around anyway, which I will post a picture of. I just wear it around my neck but under my shirt when I have the ebike with me. Works great for me. The price was great for what this thing does. If you get a good lock and have this thing armed, I mean, as soon as a person would go to position their bolt cutter or angle grinder, this thing will start making some noise... very loud noise, and you really have to be in the hood for this to go unnoticed and for it not to scare the hell out of them. When I go into a store in the day I just park the bike in a car spot and arm the alarm. It ain't going anywhere. Try out a flat lanyard like in this photo for the fob and it should not break. For me, this is an easy five star item. I waited a little while to write the review just in case it broke early on but I have about a hundred miles on the bike and everything is perfectly cromulent. I recommend it. Thank you.

You don’t want not know when some rascal is touching your bike.This alarm is loud and work like a car alarm, it gives off a loud warning to rascals let them know that you know.Now of course you want to be near to here it talking to you in it’s beep talk then you follow threw checking on it (at least you will have a chance to ubject someone stealing or vandalizing it. Seller gave me a good price and shipped it out fast delivered to my door.Yea still have still works and still have my e-bike and all intact. Thanks

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.

Amazing! Loud, easy installation.

Ebike thefts are rampant in my city. This helps deter thefts. Really loud and works just like a car alarm.

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.

After 2 years of buying still working well. They Key chain battery is still working. But buzzer's battery I changed few days ago. Very good build quality.

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.
