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

Very good and very loud. Good product

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.

Strong in the Force, this alarm is. Purchased to safeguard my luggage while traveling, I did. Loud, it is—startle even the boldest of thieves, it shall. The remote, simple to use, much like wielding a lightsaber, but without the risk of losing a limb. Test it, I have. Fail, it does not. Reliable and steadfast, like a Jedi Knight standing watch over the Temple. Versatile, this device is. Not just for luggage—your bicycle, motorcycle, scooter, or even your mailbox, it can protect. Hide in shadows, thieves may try, but flee in fear, they shall! Hmmm… a worthy investment, this is. Protect your possessions, you must. May security be with you!

Works but I don’t understand how to change the sensitivity!

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..

So far so good - very 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.

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.

Bought this for my e-bike, and installed it in the basket with the controller. It works well, but I was unable to adjust the sensitivity - the default seems ok though. I think installing in a location that is not easily accessible is important because if you can see and access the device you could probably disable the alarm by covering it with something to muffle the sound. Would not recommend simply zip tying to the frame. Nice loud alarm and works well when used with a good bike lock.

Works really good Extremely Loud easy to hook up and install

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.

Sonnerie très forte 👍

very nice good

Works good still trying to figure out the instructions they are useless
