No bike can be guarded for 100%, but you can make it harder/longer to steal. Using several cables/locks prevents an easy/quick theft. But you need to carry/use several locks with you.

The solution is a lock with 3 cables and just 1 key. You can use 3 cables to secure frame, front and rear wheels in any combination. Locking works as with usual cable lockers by inserting and fixing the locking end into the hole, but you need to use just one key to unlock all three. Locking holes are placed on 3 separately rotating cylinders, this allows easier positioning of the cable in the hole.

Version B includes U-lock which is harder/longer to destroy, and two cables.
