Security lock company Yale have released a new range of alarmed locks.
The alarms, which will be available in Mini, Standard and Maxi sizes, use a combination cable lock and tamper alarm, which is triggered if the cable is cut or the case is attacked. An optional motion sensor setting can also be used when your belongings are away from view.
The Standard and Maxi sizes will be suited for bike security, as they have a 110dB alarm and come with a 12mm by 1500mm and 20mm by 850mm strong steel cable.
The locks retail at £13.99 upwards here
