Abus Alarmbox review

A loud and robust alarm for an extra layer of security when locking up your bike

Cycling Weekly Verdict

A robust, solidly built and well-calibrated alarm unit. For trips into town and on overnight bikepacking or cycle touring trips, the Alarmbox provides a welcome extra layer of security. However, in the majority of cases getting a lock with a built-in alarm would represent better value for money.

With a long history of producing quality security products, Abus is perhaps best known to the cycling world for its bike locks and more recently helmets – but the Abus Alarmbox is neither of those. Its function is to sound an attention-grabbing alert if it detects any tampering via its inbuilt motion sensor.

Abus makes the point that a skilled thief could discreetly pick a bike lock on a busy street without attracting much attention – which is what the Alarmbox is designed to guard against. It’s also suggested that the Alarmbox could be used on scooters, barbecues, buggies, or anything else that might benefit from being alarmed.
