What It Is

This is a wireless motion sensor alarm that emits a 110dB siren when it detects movement, designed to deter theft on bicycles, e-bikes, and motorcycles. It’s a universal anti-theft accessory, not a mower part—intended for outdoor power equipment like lawn tractors or zero-turn mowers left in sheds or driveways.

Fitment & Compatibility

This alarm is not mower-specific; it mounts via adhesive or zip ties to any metal or plastic frame. Before buying, check that your mower has a flat, clean surface (e.g., frame tube, battery compartment lid) at least 3 inches long for the sensor. It works on gas or electric mowers, but avoid mounting near hot engine parts (e.g., exhaust) or moving belts. No OEM/aftermarket fitment issues—universal, but waterproof rating is IPX4 (splash-proof), not submersible, so keep it out of direct rain or washdowns.

Key Things to Know

• Installation: Easy—peel-and-stick adhesive or zip-tie mount. No wiring required; remote and sensor are battery-powered (CR2032 included). Test placement to avoid false triggers from wind or vibration.
• Volume: 110dB is loud, but adjustable via remote (low/medium/high). On a mower, high may be overkill indoors; medium is fine for driveway or shed.
• Sensitivity: Motion sensor can trigger from passing cars or animals. Adjust sensitivity on the remote to reduce false alarms. Expect some battery drain if used daily (sensor lasts ~6 months, remote ~1 year).
• Common Gotcha: Adhesive may fail on oily or painted surfaces. Clean with alcohol first. For rough mower frames, use zip ties instead.

Should You Buy It

Buy if you park your mower outside or in a shared shed and want a cheap, loud deterrent for $16. It’s not a replacement for a disc lock or chain, but it’s a solid extra layer for low-risk theft areas. Skip if you need a hardwired system or have a mower that sits in heavy rain—this is splash-proof, not weatherproof.
