Japard Loudest 113dB Bike Alarm with Remote, Wireless Anti-Theft Vibration Motion Sensor, IP55 Waterproof Bicycle Motorcycle Bell, KS-SF22R

What It Is

This is a wireless, 113dB anti-theft alarm system designed for bicycles, motorcycles, and electric scooters—not for lawn mowers. It uses a vibration motion sensor to trigger a loud siren and remote arming/disarming.

Fitment & Compatibility

This alarm is not intended for lawn mowers or any outdoor power equipment. It requires a handlebar or frame mount (included) and works on bikes, motorcycles, and scooters with a tubular or flat surface 20–40mm in diameter. Before buying, confirm your vehicle’s handlebar or frame size. It is not compatible with lawn mower decks, engine blocks, or mower batteries (uses CR2032 coin cell, not 12V). No OEM or aftermarket mower part cross-reference exists.

Key Things to Know

• Not for mowers: This is a bike/scooter alarm. Using it on a lawn mower would require creative mounting and likely fail due to vibration from the engine.
• Volume & sensitivity: 113dB is very loud, but the motion sensor may trigger falsely on a mower from engine vibration or wind. Sensitivity is adjustable via remote.
• Installation: Simple strap-on mount—no wiring. Takes 2 minutes on a bike. On a mower, you’d need to secure it to a non-vibrating part (e.g., seat frame) which is impractical.
• Water resistance: IP55 means it can handle rain but not a pressure washer or submersion.

Should You Buy It

Buy this if you need a loud, easy-to-install alarm for a bicycle, motorcycle, or scooter. Skip it for lawn mowers—it won’t mount securely, will false-alarm from engine vibration, and offers no practical theft protection for mower equipment.
