Locking without keys: the Steel-O-Flex™ Tresorflex 6615C makes it possible. And protects with its steely combination of cable and sleeve coating.

Steel-O-Flex Tresorflex 6615C


Instead of searching for your key, with the Steel-O-Flex™ Tresorflex 6615C it’s simply a case of: select the numerical code you want, set the number reel and secure your bike.

This clever cable lock is full of ABUS quality: the 15 mm steel sleeves that envelop the steel cable makes things twice as difficult for thieves. In addition, the mechanism of the Steel-O-Flex™ Tresorflex 6615C is effectively equipped to protect against manipulation thanks to its special touch protection.

Comfort first: the digits on the number wheel are so clearly moulded that you are still able to set the right combination for unlocking even at night - just by touching them. And the Snap Cage bracket is both universally mountable and also simple and convenient to use in daily life.


  • 15 mm overlapping steel sleeves protect the inner steel cable
  • Plastic coating to prevent damage to the bicycle’s paintwork
  • Two-component number reels guarantee life-long visibility of the digits
  • Special touch protection for increased security against unauthorised access to the code through manipulation of the mechanism
  • Dark-touch function facilitates use in the dark thanks to special imprinting
  • Individually configurable code

Operation and use:

  • Good protection where the risk of theft is low
  • Recommended for protecting entry-level and children's bicycles


  • Snap Cage bracket for universal mounting


  • With its steel sleeves, the Steel-O-Flex™ locks offer a considerably greater degree of security with much higher flexibility (double protection) than simple cable locks
  • The combination lock is great for use by several people
