Compact USB-rechargeable bike alarm

The BONAEVER alarm secures bicycles, motorcycles, scooters and luggage with a 110 dB siren triggered by a 3D motion sensor. A USB-rechargeable battery delivers up to three months of operation per charge. The unit measures 45 mm by 45 mm by 32 mm and mounts via double-sided adhesive, cable ties or the included adjustable bracket. IP54 water resistance allows reliable outdoor use.

Motion sensitivity and remote ranging

Seven sensitivity levels and three volume settings let riders tune the alarm to their environment. The wireless remote arms and disarms the system from up to 229 ft away and activates a locate function with three selectable ringtones. No active cooling or mains power is required, so the device adds no noise or power draw to the host vehicle.

Replaces basic cable locks and fixed alarms

This alarm upgrades from passive locks or non-rechargeable units that lack motion detection and remote ranging. The jump is worth it when a rider needs audible deterrence, adjustable sensitivity and a find-my-bike feature across multiple vehicle types. It does not suit users who require GPS tracking, smartphone integration or a hard-wired vehicle power connection.

Questions about this item

How do I mount the alarm and which step do people skip?

Choose the bracket, zip tie or adhesive pad; clean the surface thoroughly before applying the adhesive or the unit can detach.

What will need replacing after the three-month charge cycle?

How long will the 110 dB siren sound before the battery runs down?

The alarm draws power only when triggered; the 3-month figure applies to standby, not continuous sounding.
