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.

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.

Works great, gave me piece of mind leaving my motorcycle in a hotel parking lot.

Alarm works well and is definitely loud. The fob also works well. Attached under the seat of my e-bike and hides well. My concern is the alarm and changing the batteries. I took the alarm apart and there are 4 tabs inside the compartment to connect both halves of the alarm. I was very concerned that the tabs would break when I literally had to rip both halves apart. Hopefully the batteries will last a long time because the weak spot on this alarm are those tabs. I can see the tabs as possibly the first breaking point on this alarm. Hopefully that won't be the case but it is definitely a concern. Time will tell.

Just what I needed to protect my e-bike at the super store. I have it on max volume and sensitivity and it react appropriately to any purposefully movement, but has never sounded off by itself. I liked it so much I bought a second one for my motorcycle.

I came quickly and works great so far. Its definitely loud enough to get noticed

Very loud, and sensitive

Used to love this brand. Unfortunatley this time the alarm seems to be way quieter than the last even on the highest setting. Sad.
