Ideal bike security solution when keys are inconvenient. Combination can be set and changed easily and as often as desired. Ergonomically-designed digit wheels are easy to use, even in the dark. Equipped with carrier for the seatpost bolt for easy transport.
The Abus Tresor combination locks have a weak spot that seasoned bike thieves know how to exploit, but hacksawing in between combination wheels. My bike was stolen easily in this way despite paying AUD $80 for a good quality thick Abus Tresor combination lock and connecting it to a secure rack. Key-based locks preferable.
