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

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.

Excellent little alarm. I placed it on my motorcycle and was pleasantly surprised on how loud this is. The remote is easy to use and the sensitivity level is perfect. No too high not to low. Just enough to set alarm off with movement. Also place and air tag inside the seat for added security. Would highly recommend this alarm.

This is the second one from them that I have purchased, and I have never had an issue. It is easy to setup and use. When the alarm goes off it is nice and loud. I have only a small complaint: I am not fond of the do re mi to set the sensitivity level, otherwise pretty close to perfect.

Bought to use on motorcycle, but put a small zip tie on (string would work) and hung on hotel room door to use as an alarm in a forced entry. We closed the bathroom door, near the alarm too hard, alarm reacted. Very pleased. Wish it was even louder, execpt when its our error!

My wife recently purchased an electric trike for $3500. I want to do everything I can to keep it from b eing stolen. We purchased a very strong lock and chain. I purchased this alarm to bring attention to the trike if someone tries to take it. When the alarm is set it will give a warning if it senses movement. If it continues to sense movement it will go off making a loud attention getting sound. I used included zip ties to secure the alarm to the front basket on the trike. It is the same color as the basket and blends in so it's not something that stands out as easy to see. The included remote works well.

This alarm is extremely loud it will definitely keep people away

It works really well.

Wind sets it off and then you can barely hear it
