Cruxer Bike Alarm Remote Motion Sensor System - 110dB Motorcycle

In this review the Cruxer Bike Alarm Remote Motion Sensor System is evaluated as a straightforward, purpose-built solution for riders and vehicle owners who want a compact anti-theft alert that is easy to fit and hard to ignore. The bottom line: it is best for cyclists, scooter and motorcycle owners who need a loud, weatherproof vibration alarm with adjustable sensitivity and a simple key fob to arm and disarm; the 3D displacement sensor and special algorithms cut down on false triggers while still giving a rapid warning when movement is detected.

Key Features

• 3D displacement sensor: Accurately detects movement in three axes so the alarm responds to tipping or pushing rather than only simple shocks.
• Adjustable sensitivity: Seven sensitivity levels let users tune the unit from slight movement detection to only strong impacts, reducing nuisance alerts in busy areas.
• Variable volume and ringtones: Three volume levels and ringtones ranging up to 113dB provide a loud, attention-grabbing siren suitable for outdoor use.
• IP55 waterproofing: A weather resistant design makes the alarm suitable for bicycles, scooters, motorcycles and even exterior windows and doors in wet conditions.
• Long battery life and remote range: Uses three replaceable AAA batteries for 1-3 months of typical daily use and a remote with up to about 50 m/164 ft lab detection range for one-button arm/disarm.
• Flexible installation: Includes both strap and double-sided tape mounting options so it can be attached to round frames or smooth surfaces without extra tools.

Who It's For

The Cruxer alarm is ideal for riders of electric bikes, commuter bicycles, scooters and motorcycles who want a visible, audible deterrent that can be mounted almost anywhere and configured to the surroundings. Its compact size and strap or tape mounting make it a practical add-on for trailers, gates or even doors where a simple vibration-triggered siren is useful.

It is less suitable for users who need professional GPS tracking, remote smartphone alerts or a fully integrated immobilizer system; those wanting cloud alerts or vehicle tracking should consider a different class of device. Also, anyone requiring extremely long battery life without replacing AAA cells may want a hardwired or rechargeable alternative.
