So tough, it was designed for motorcycles!
Like the “Little Brother” disk lock, the “Big Brother” disk lock secures your wheel in place, forcing interested thieves to have to lift and carry your 50+ Lb bike away. However, with the added feature of the 110dB alarm, they now would have to carry away a 50+ Lb shrieking bike. For the size, this lock is the best deterrent available. For complete peace of mind, pair it with the “Squeezebox” folding lock for the added visual deterrent.
