The BORDO family of locks combine the rigidity of a U-lock and the flexbility of a chain lock, with links that fold together into a compact carrying mount. 

Adding the alarm adds another whole layer of protection: as soon as someone starts to tamper with your lock, a warning alarm begins to sound. If this isn't enough to deter the thief and they persist, a louder, 100 dB alarm begins to sound, sure to draw the attention of those nearby. If the vibration sensor was just bumped by someone parking next to you, or an errant football, this full alarm will not activate.
