There are already plenty of options when it comes to keeping people from stealing your whole bike, but what if you also want to guard against people stealing bits of it? Well, you could buy components that can only be removed with their own special tool, or replace all of your mounting bolts with ones that require a key to take off. Sphyke is now offering a third alternative – its C3N system replaces a bike's existing nuts and bolts with ones that incorporate a tiny combination lock.
