What It Is

This is a wireless motion sensor alarm system for bicycles, e-bikes, motorcycles, and scooters. It detects vibration or movement and sounds a 120dB siren, plus sends alerts via a remote fob.

Fitment & Compatibility

• Mount type: Universal handlebar mount (fits bars 22–32mm diameter). Check your bike/scooter’s handlebar or frame tube size before buying.
• Power: USB rechargeable (micro-USB cable included). No hardwiring needed, so it works on any 12V or battery-powered vehicle.
• Not for: Lawn mowers, tractors, or gas-powered equipment. This is designed for personal electric vehicles and cycles only.
• IP rating: IPX5 water-resistant – fine for rain, not for submersion or pressure washing.

Key Things to Know

• Installation: Tool-free – strap mount tightens with a screw. Takes 2 minutes. Remote pairing is automatic out of box.
• False alarms: Sensitivity is adjustable via the remote (low/medium/high). On high, wind or a bump can trigger it. Set to medium for most use.
• Battery life: About 2–3 months on a full charge with normal use. Low battery chirps as a warning. Charging takes 1–2 hours.
• Range: Remote works up to 50–100 feet line-of-sight. Walls cut that significantly.

Should You Buy It

If you park your bike, scooter, or e-bike outside or in a shared garage and want a loud deterrent without wiring, this is a solid, cheap upgrade. Skip it if you need GPS tracking or geofencing – this is a simple motion alarm only.
