113dB Bike Alarm, Anti Theft Bike Alarm with Remote, Electric Ecooter Alarm Wireless Vibration Motion Sensor IP65 Waterproof for Motorcycle Golf Car Trailer Mailbox Garage Door Home Security

What It Is

This is a wireless vibration/motion-sensing alarm system with remote control, designed to deter theft on bikes, e-scooters, golf carts, trailers, mailboxes, and garage doors. It emits a loud 113dB siren when triggered, and is IP65-rated for outdoor use.

Fitment & Compatibility

Before buying, verify the mounting surface is clean, flat, and dry—the adhesive bracket works best on metal or hard plastic. The alarm is universal, so no specific brand or model fitment is required. However, check the dimensions: the unit is about 2.5 x 1.5 x 0.8 inches, so ensure it fits on your handlebars, frame, or inside a trailer/mailbox without interfering with moving parts. The remote works up to 100 feet, but walls or metal enclosures reduce range. No OEM compatibility issues—it’s a standalone add-on.

Key Things to Know

• Installation: Easy—peel and stick with 3M tape or screw-mount. No wiring needed, but the adhesive may weaken in extreme heat (above 120°F) or on rough surfaces.
• Sensitivity: Adjustable via a small dial; set it low for windy areas or bumpy rides to avoid false alarms. Too high, and it’ll trigger on heavy rain or passing trucks.
• Battery life: Runs on a CR1632 coin cell (included). Expect 3–6 months with normal use; replace when the siren weakens or remote range drops.
• Waterproofing: IP65 means it’s dust-tight and resists water jets, but don’t submerge it. The remote is not waterproof—keep it dry.

Should You Buy It

Buy this if you need a cheap, no-wire theft deterrent for a bike, e-scooter, or small outdoor item like a mailbox or trailer. It’s not for high-security needs (the siren is loud but the unit can be pried off), but it’s a solid, easy-install option for casual protection. Skip it if you want GPS tracking or a hardwired, tamper-proof system.
