WSDCAM 113dB Loud Anti Theft Vibration Sensor Alarm Systems for Electric Bike Motorcycle Golf Car Trailer Mailbox Garage Door Waterproof Home Security Bike Accessories Bike Alarm with Remote

For the price, you can't really find a better theft deterrent for a bike, scooter, backpack, briefcase, laptop, etc. Yes it has limitations but remember it's less than $20. The remote works from about 100 ft away. The alarm can be quite loud if you position it properly. It's also very sensitive. You can adjust the volume of the alarm and the sensitivity. There's also a safety feature that if the alarm tilts on its side, it will beep an SOS until it's returned to its normal position. There's also a locate feature that will chirp the alarm to help you find your item or device. Battery life is also pretty good. Expect 6 months on the AAA batteries in the alarm and about a year on the remote (arming and disarming a couple times a day). The alarm really shouldn't be exposed to rain, but if it's mounted underneath something of it will withstand splashing and dirt and can be wiped clean. The battery compartment does have a gasket to help protect the internals. I own several of these and they've lasted years.

Very good and very loud. Good product

third one I have bought and used for various applications, Fully customizable for your particular needs Great value for the price. Long battery life.

So far so good - effective option for the price. It doesn't take much movement to trigger it, and I really like how it gives a 'warning' first, before fully alarming. Using it for my motorcycle - just keep it in the trunk so it's out of sight and not accessible without the key. Would definitely recommend. Update 7/14/2026. Goes through batteries pretty quickly when you arm it. Something else I also discovered - you may want to remove the little screw because when the batteries are getting close to dying and you arm it, it just beeps and you can't do anything about it unless you pop the cover and pull the batteries. Otherwise it will just beep for hours until the batteries completely die. Either that or keep a tiny philips head screwdriver with it/you at all times.

This thing is LOUD!!! Got this for my golf cart. Zip tied it to the frame under the seat, perfect sensitivity. I’ll forget to disarm it and sit down and the warning chirp makes me jump every time. The remote fob also works from long distances! Totally recommend as a theft deterrent on all types of applications! It will totally send wanna be thieves running. Great value.

Finally got 2 to pair up.. put 2 in the box.. Will be loud.. take the battery out for a minute..Hold the bell down until it stops. Then push lock.. they sould pair up.. Staying in a cheap rv park for now.. Got a few shady characters running around.. Got these because I got a nice cut in my tent flap or it was just wear and tear.. Already went off at 4am.. Because someone might have been graby.. Didn't get up quick enough to see.. But better safe then sorry..

Well, it does what it’s intended for. I like it. Hubs was surprised by sounds. A key fob, easily used. I don’t keep it actively on when it’s locked in garage because a slight touch will set it off. It’s a deterrent and loud enough to startle. Although, I don’t expect to be leaving my EV bike anytime soon, or unattended but to let people know, it’s being watched. Just a bit of peace and mind.

Useless e-waste. Maybe I got a dud or something, but this is useless e-waste and I'm $20 poorer. I attached the alarm to my electric scooter. Even trying out different sensitivity levels, I can grab the handlebars and walk away without even being careful about it and it won't trip the alarm. You can walk the scooter down a pitted gravel driveway and not trip the alarm. Standing on top of the scooter is the ONLY way to trigger the sensor. Well that only sounds half useless, right? If I hadn't just spend $20 on the alarm, I would've laughed when I heard how quiet it is. I've had phones with louder speakers. Changing the volume setting doesn't actually change the volume. Yes I'm sure I have the right setting, because there are 3 volume settings and 7 sensitivity settings, it's not that hard to figure out if you read the instruction manual. It's so weak that I think that the scooter actually has higher chance of being stolen if you use it. Arming just draws peoples attention, and lets them know that it's whisper quiet. If this alarm went off in my garage, I wouldn't be ab;e to hear it from my house that's 15 feet away. The "silent alarm" shuts off after one 30 second cycle. Since you can't leave 0 star reviews, I'll credit that 1 star to being easy to install garbage, which is better than difficult to install garbage.

Reasonable good product

Preis-Leistung Top! Macht was es soll.

Je l'ai installé sur mon vélo ça fonctionne très bien au premier toucher il avertis avec un son de bosseur et si tu retouche au vélo attention l'alarme se déclenche très sensible. Il est Super.

Bit Pricey Purchased on April 5th 2025 for my BMW G 310 GS. The product gives a solid sense of security and seems reliable so far. While the price feels a bit on the higher side, the quality makes it worth considering. I’d recommend the supplier consider a more competitive price point. Overall, worth buying. Will update here if I face any issues.

It works great
