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

This alarm is definitely loud and will attract attention. The levels of sensitivity are adjustable, but a slight nudge will set this alarm off, even with that adjustment.

Nice and loud. A must for ebikes. Good deterrent.

These work great! I lost my first one and was delighted that I could pair my original remote with the replacement quite easily. Now I have one for both sets of keys. The charge lasts forever. Seriously..I got my dad one, and he left it armed all winter, and still hasn't charged it in over a year. They're also pretty loud! Expect to be startled if you forget you left it armed.

PROS: The remote works well from inside or outside the vehicle and provides an audible sound when arming and disarming with the lock and unlock buttons. The 4 buttons on the remote have large, clear, easy-to-read white print, which is nice too, plus a sturdy quick release clip. CONS: The reason for 4 stars instead of 5 is that even on its highest sensitivity setting, it is not ideal. I placed the sensor in the driver's side door pocket of my mid-sized SUV using the provided double-sided tape. From outside of the vehicle, If I bang on the driver's side door panel or window, the alarm will go off. But if I bang elsewhere on the vehicle, the alarm does not go off. It might go off if I actually broke one of the other windows or if the car was hit fairly hard by something. Same goes for the tilt sensor. Seems to work well but only if it's mounted lying flat as opposed to on its side.

Excellent alarm. Best I have tried

Works well. I bouht two. One is connected to my trash bin lid via velcro (I have to remove it on pickup days). I did this because despite the bike chain accross my lid, people still can lift a corner to throw their dog doodoo bags inside. The other is connected to a small wooden box with the alarm inside, connected to fishing line that knocks the box over and the alarm triggers. The other end of the fishing line temporarily connects to various used amazon boxes that I lay on the porch for evil porch pirates! Works like a charm, and the alarm doesn't end up getting stolen with the bait package

Works just as described. Love that it’s rechargeable!

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.

Works really good Extremely Loud easy to hook up and install

It is all good and it is nice and loud the way I like it

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.

The sound is awesome , really loud! The remote works great, and I love that it’s rechargeable. So nice not having to buy batteries all the time! I'll buy again.

Sonnerie très forte 👍
