Review on 🚲 Onvian Wireless Bike Alarm with Remote - Waterproof Anti-Theft Security System for Bicycle, Motorcycle, Electric Scooter, Moped, etc. - 113dB by Alex Webster

This is a great bang for your buck. Motion detection levels range from "Oops, I was breathing too heavily" to "Oops, I tripped over this thing". There's not really a setting that allows for easy movement, it's either insanely sensitive or overly sensitive. I first tested it by putting it in a drawer in the kitchen. On the most sensitive setting, I couldn't even touch the drawer handle for it not to work. With minimal sensitivity, if I slowly opened the drawer, I was able to open it without triggering the motion detector most of the time. However, remember that this is a box with smooth wheels. As for the audio, it's deafeningly loud indoors. This is great for some use cases, but not great for me. I wanted something loud enough to be heard from my office while the alarm went off outside. That meant there was a living wall between me and the alarm. Surprisingly, it doesn't work for that. It's amazing how an open space absorbs sound so that something so loud inside bouncing off the walls sounds like birdsong outside. One star only because I think it could be better. But it's still a major deterrent to anyone messing with my property.
