Foldylock

Protect your bike with the easy storing anti-rusting Foldylock. Just like the tale of the three bears, this number is “just right.” The six hardened steel links protection covered in plastic stretch out to reveal a 90 cm sturdy lock that simply attaches to the frame on the water bottle holder by either fixing screws or two special designed straps. Gotta get out of here quick, no problem, it performs both locking and unlocking within just 30 seconds time. The design is elegant and the security is certain, check out their Kickstarter video here.
