Guardian Alarm Dual-Alert Bike & Motorcycle Vibration Alarm — 110dB Siren, Long-Range Remote

The Guardian Alarm Dual Alert System combines a 110dB vibration-triggered siren with a long-range wireless remote to deter theft and notify you instantly.

Compact and weather-resistant, this alarm is designed for bikes, e-bikes, motorcycles, scooters, trailers and outdoor equipment. It uses intelligent vibration sensing and adjustable sensitivity to separate real tampering from harmless bumps, while a loud, directional siren and remote notifications make theft attempts immediately obvious even at a distance.

How loud is the alarm and will it really scare thieves off?

The siren emits up to 110dB with a six-directional sound pattern designed to remain audible even if the unit is partially covered. That intensity is intended to attract attention quickly and increase the chance a theft attempt is interrupted.

• 110dB peak siren with multi-directional sound design
• Alarm remains loud when mounted under cages or against frames
• Instant remote alerts ensure you know even if you’re out of earshot

How does the vibration sensor avoid false alarms?

Built-in algorithms analyze impact patterns so the unit responds to deliberate tampering rather than wind or light knocks. Choose from three sensitivity levels to match busy urban settings or quiet storage locations.

• Three sensitivity modes: high, medium, low
• Smart filtering reduces nuisance activations from minor impacts
• Easy switching to customize for parking environment

What range can I expect from the wireless remote and how many devices can I pair?

The system supports long-range alerts so you get notified even when you’re not nearby. The alarm and remote communicate across up to 1600 ft (500 m) in open areas, with reliable penetration through typical building materials for everyday use.

• Up to 1600 ft (500 m) open-area range; ~500 ft (150 m) practical proximity feedback
• Works through two concrete walls up to ~70 ft (20 m)
• Unlimited remotes can be paired for shared alerts; single remote controls up to 3 alarms

How durable is the device for outdoor and vehicle use?

The Guardian Alarm is engineered for outdoor reliability: it’s dust- and rain-resistant, tolerates wide temperatures, and uses user-replaceable batteries for long life and low environmental impact. Mounting hardware is tamper-resistant so you can hide the unit without sacrificing effectiveness.

• Operates from -4°F to 140°F (-20°C to 60°C)
• Weather-resistant housing and tamper-proof mounting screws
• Standard CR2032 batteries for easy replacement

Who is this for? The Guardian Alarm Dual Alert System is aimed at cyclists, riders and outdoor enthusiasts who want a compact, discreet theft deterrent that pairs audible deterrence with long-range notifications. It’s ideal for anyone who parks in public spaces, stores gear outdoors, or wants a low-maintenance add-on to locks and trackers for multi-layered protection.
