Bike Alarm Wireless Vibration Motion Sensor, Bike Alarm with Remote, Anti Theft for Electric Bike Motorcycle Golf Car Trailer Mailbox 113dB Loud IP65 Waterproof

What It Is

This is a wireless vibration-sensing alarm system that triggers a 113dB siren when motion or tilt is detected. It’s designed for electric bikes, motorcycles, golf carts, trailers, mailboxes, and any other outdoor equipment you want to secure from theft.

Fitment & Compatibility

• Mounting location: Attaches to any flat, clean surface using adhesive or screws. Works on metal, plastic, or wood surfaces (e.g., frame, mailbox door, trailer hitch).
• Power: Requires two CR2032 coin-cell batteries (included). No hardwiring needed.
• Remote range: Up to 200 feet line-of-sight (may drop through metal enclosures or thick walls).
• Water resistance: IP65 rated – fine for rain, but avoid submersion or direct pressure washing.
• What to check before buying:
  • Surface area must be dry, clean, and at least 2x2 inches for adhesive pad.
  • Ensure your equipment has a flat, accessible spot to mount the sensor (no curved or heavily textured surfaces).
  • Verify you can reach the unit to change batteries (every 6–12 months depending on use).

Key Things to Know

• Installation difficulty: Easy – peel, stick, pair remote. Takes under 5 minutes.
• Sensitivity adjustment: Comes with a dial to set vibration sensitivity (high/low). Set too high, and wind or bumps from a trailer can trigger false alarms.
• Battery life: Good for ~6 months with moderate use. Low battery indicator on remote helps you know when to swap.
• Common gotchas:
  • The remote is small and easy to lose – keep it on a keychain.
  • If mounting on a metal surface, double-check adhesive grip; screw-mount option is more secure for heavy vibration (like on a trailer).
  • Sound is genuinely loud (113dB) – may disturb neighbors in quiet areas.

Should You Buy It

Buy this if you want a cheap, no-wire theft deterrent for a bike, golf cart, or mailbox that’s parked outside. It’s not a GPS tracker or immobilizer – it’s a loud scare tactic. Best for low-risk areas where you just need to discourage casual thieves. Skip it if you need real-time tracking or a system that disables the vehicle.
