The Ultimate 420 U-lock combines ABUS security technology and compact design into a lock that will make thieves tear their hair out.

The Ultimate 420 radiates a feeling of security through its appearance alone.

There are locks and then there is the Ultimate 420. If you are looking for a shackle lock that will deter potential thieves just by looking at it, then you don't have to look far. Thirteen millimetres of hardened special steel and aggressive colouring make it immediately clear to any bicycle thief that they have no chance here.
At the same time, the Ultimate 420 is so compact that you can easily stow it away. It finds its place in every backpack and bag and is therefore always with you when you need to secure your valuable bicycle.
