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

Just as shown in the photo. Good sturdy material. Easy to install in motorcycle. Loud. Very happy.

Ever since I installed this device, people don’t touch my bike

These alarms are great for our ebikes! Easy to install

Seriously thought this was going to be a joke item or gimmick item fit perfectly in a secure location on my bike and works amazing so loud I had to turn the volume down to medium and does what its supposed to do the key fob is very lightweight and doesnt seem incredibly durable but again I got a two pack for $20 you get what you pay for but I would definitely recommend this. Feel super bad ass when people see me walk away and I do the bloop bloop of a car alarm key fob thing Ive my shoulder when walking away 8P

After a string of bicycle thefts in our R.V. park I purchased two of these they work great!

Works great

Easy to set up and install.

Put one on golf cart and one on riding lawnmower

Good

I tried this in several places on a Prius using different methods of attachment. I shook the car as violently as I could and the device would not sound the alarm beyond an initial beep. The alarm gives a warning sound when first shaken or vibrated. That gives the thief time to locate and muffle the alarm. The reviews state that on a bicycle the alarm works when the bike is moved from a vertical position down to a horizontal. Hows that going to work for a Prius? It cannot be placed on the exhaust system directly. Heat in excess of 500°F would melt the plastic case and the circuits. There are better alarms some available on Amazon for catalytic converter protection.
