A device for securing a bicycle, comprising an immobilising jam secured to the pedal crank arm assembly, whilst engaging the bicycle frame and rear wheel, thus preventing the bicycle from being ridden or free wheeled away. The jam member may be cylindrical and have a rotating hardened sleeve to resist cutting. The device may be secured to a pedal axle and include a sprung plunger to cater for differing axle sizes. A chain stay guard may provide a means for fixating the jam member relative to the chain stay. The jam member may also include a feature such as a loop for the connection of an additional lock, such as a cable lock. |
