Wsdcam Bike Alarm with Remote 2 Pack, 113dB Wireless Anti-Theft Vibration Motorcycle Bicycle Alarm Vehicle Security Alarm System (Blue)

Delivery was fast product was nice, easy to install and use.

Excellent product and has multiple uses.

We mounted one on each of our Lectric Xp bikes. With a few real thick zip ties (the ones included are useless) they fit perfectly and solidly in the bike rack. And once you load your cargo or in my case mount a thin board on top of the rack. There will be no access for anyone to reach or destroy the alarm if it goes off. It is the perfect fit and hiding spot for those with a similar bike or rack set up. Although, I know some hide it in the seat above the post. It has enough air gap to hear the horn/alarm and cant be messed with or even found/seen. Now as for how well the alarm works. It arms and works great as a bell with the 3 tone options. No idea if it will deter thieves. But I know I would not be able to waste much time trying to cut any locks with this alarm blaring for the 30 seconds it takes to reset. You can see in my photos that it fits perfectly flush on the rear rack. So it is easy to place cargo on the rack and not touch the alarm. I installed it facing down to the fender. There is only a 2 inch gap between the fender and rack so the alarm does not touch the fender and not enough room to reach alarm this way either. Once I mount the wood panel to the rack. It will be totally covered and unreachable to the average person. Sure it will add a extra step should I need to change the batteries. But minor detail. And should this post reveal a way to defeat the location. Still likely to get enough eyes on the thief to show anyone around that a bike is being stolen. Bike is only used in daytime and mostly for trail riding. For the price. This is a worth it expense to try for a well rounded security in conjunction with one or two bike lock methods. We have three!

Very loud protection! It will do the job. Easy to conceal.

Easy to program and use. Great deterrent. Liked price and shipped quickly.

Seems very sensitive, just a slight bump sets it off. Just what I needed.

Easy to install and motion detectin is awesome!!!

They wont prevent someone from taking your stuff if they think no one can hear but I have one on my back gate, on my e-Bike, and even used them on campaign signs in my yard! If someone is opportunistically trying to break in and grab, stuns them and they run off. I have bought these over and over again - do know that when they stop working you can replace the battery... took me a while to know that.

I was skeptical! We set them and I forgot my phone. When removing my phone I set it off. It is loud and a great deterrent. I recommend 100%.

They make noise when the bike is moved, then pause and make more noise for longer if it is moved again. Since bike locks seem so vulnerable, an alarm will draw attention, at least.
