Küat Bottle Lock
Bike rack maker Kuat (Koo-at) has released a convenient and clever contraption for keeping your wheels safe. What looks like a typical bike water bottle from the outside actually contains a five foot internally coiled 8mm cable thats designed to lock back into itself. The bottle also sports a lower storage compartment for stashing keys and other small items. As with most bike locks, it probably won’t stop a truly determined thief — but it does store nicely when not in use and should deter amateurs. Then again, if wearing chains across your chest happens to be your thing — this may not be a solution for you.
