WSDCAM USB Rechargeable Bike Alarm with Remote, 110dB Loud Wireless Anti Theft Vibration Motion Sensor Vehicle Security Alarm System Waterproof Bicycle Trailer Motorcycle Alarm - 2 Pack

What It Is

A wireless, rechargeable alarm system that attaches to a bike, trailer, motorcycle, or lawn mower to deter theft via a 110dB siren triggered by vibration or motion. It’s designed for outdoor power equipment and vehicles that are left unattended in driveways, sheds, or job sites.

Fitment & Compatibility

• Not model-specific: Works on any machine with a flat, clean surface (frame tube, mower deck, handlebar, or trailer tongue) where the adhesive mount or zip ties can attach.
• Size check: Alarm unit is about 2.5 x 1.5 x 1.2 inches—ensure it doesn’t interfere with moving parts (blades, belts, wheels) or get crushed under seats.
• Power requirement: No hardwiring needed—runs on built-in rechargeable battery via micro-USB. Must be charged before first use (charge time ~2-3 hours).
• Waterproof rating: IP65 (splash-proof, not submersible). Avoid mounting where direct hose spray or rain pools.

Key Things to Know

• Installation difficulty: Easy—peel adhesive pad or use included zip ties. Remote pairing takes 30 seconds (press button on alarm, then remote). No tools required.
• Battery life: Lasts 30-60 days per charge depending on sensitivity setting and trigger frequency. Low battery beep can be annoying if ignored.
• False triggers: Wind, animals, or heavy vibration (e.g., mower engine running) can set it off. Adjust sensitivity via remote (three levels) to reduce nuisance alarms.
• Volume: 110dB is loud enough to hear from inside a house or across a yard, but not as piercing as a car alarm. Test placement to ensure it’s audible over engine noise.

Should You Buy It

Buy this if you park a lawn mower, motorcycle, or trailer outside or in a shared garage and want a low-cost, no-wire theft deterrent that’s simple to move between machines. Skip it if you need a hardwired alarm for permanent installation or a higher-decibel siren for remote job sites.
