Mengshen Wireless Vibration Alarm, Anti-Theft Burglar Alarm for Bicycle/Bike/Motorcycle/Car/Vehicles/Door/Window, 110db Super Loud (Remote Control Included)

What It Is

This is a 110dB wireless vibration alarm with remote control, designed to deter theft by triggering a loud siren when motion or vibration is detected. It’s marketed for bikes, motorcycles, cars, doors, and windows—but can be used on any stationary object you want to secure, including lawn mowers, trailers, or outdoor equipment.

Fitment & Compatibility

This is a universal accessory, not a mower-specific part. There’s no deck size, brand, or OEM fitment to check. Before buying, verify you can securely attach the unit to a clean, dry, non-moving surface (e.g., mower frame, battery box, or handlebar). It uses double-sided tape or screws (included). For outdoor use on lawn equipment, ensure the mounting spot is sheltered from direct rain or you’ll need a waterproof enclosure—this alarm is not weather-sealed. The remote operates on 433MHz; no pairing with mower electronics required.

Key Things to Know

• Volume is real: 110dB is genuinely loud—enough to startle a thief and alert you from inside a house or garage.
• Installation is easy: Stick it on with the included tape or screw it down. No wiring needed. Test sensitivity: adjust the internal dial (or use the remote) so wind or passing cars don’t set it off.
• Battery powered: Runs on 3x AAA batteries (not included). Battery life depends on how often it’s triggered; expect weeks to months. Low battery warning is audible.
• Not weatherproof: Use indoors or on covered equipment. If mounting on a mower stored outside, wrap in a bag or mount under a hood. Water damage is a common complaint.

Should You Buy It

Buy this if you want a cheap, loud, easy-to-install theft deterrent for a lawn mower, trailer, or shed—and you can keep it dry. Skip it if you need a weatherproof, hardwired system for year-round outdoor exposure.
