I've seen a lot of clever bike lock designs, but the Küat Racks Bottle Lock is definitely unique. This is a great gadget for cyclists -- a bike lock that stores as the same size and shape as a bottle of water so it fits right in your water bottle rack.
Bike theft is a real problem, but that doesn't mean ugly bike locks have to be an unfortunate side effect of bicycling around town. Most locks look rather ugly when they aren't in use. Usually they just sort of hang from your seat, haphazardly wrapped up and waiting to be looped around a lamp post.The Küat Racks Bottle Lock has a 5-foot long cable of 7.5mm braided steel that rolls up to store in the bottle-shaped case. It includes two keys and a lock, which can also be stored inside the "bottle", and weighs just 14 ounces. It would have an expected sale price of $34, if it makes it onto store shelves. That's really not so bad for a stylishly-hidden lock for your bike.
The only problem, of course, is where does your water go?
