🚲 Enhanced Security with GREENCYCLE 1 Pack Bike Alarm: Anti-Theft Vibration Alarm for E-Bikes & Electric Tricycles with Remote, Adjustable Sensitivity & Waterproof Design - 113dB Volume, SOS Function Included Review

We bought this to use on a UHaul truck during a move. It worked great, not overly sensitive but sensitive enough. It was easy to hide, easy to arm, and you could do it from a little closer than a car alarm!

Very sensitive. Can be used on a window or door. It is a very loud and piercing noise. You can hear the alarm clock outside. Easy to install, just pull the plastic tab and you're done. It has a remote control and can be used at a reasonable distance around the house or at work.

It makes us feel safer when riding on rough terrain. Tip: Set the alarm last. Don't lock it when you're not parked. You don't want it working when you're driving. And book into red-roofed hotels so you can fall right into your room. This fear has given us so much peace of mind.

I love this item. Two bikes have been stolen from my shed over the years. That gets the thief running! It's noisy. I installed it under the seat, mainly to hide it from casual inspection by a dirty, smoking thief. Combined with a good bike lock (bolted to a brick pillar) and my ring bell cam, no one might get away with my bike! One star deducted for confusing instructions/instruction manual. Much luck.

I bought this alarm system to (again) protect my Honda Element from catalytic converter theft. When I test the alarm on my bench it works fine and responds to a slight shake. When I put it in my car or attach it to a roof rack, it refuses to respond to the car's rocking (like someone using a saber saw on the exhaust system). I have no idea why rocking back and forth wouldn't work, but it renders the alarm useless for my purpose. Disappointing.
