The Auvray C-Bloc chain lock embodies French expertise in two-wheeler protection, with an ingenious design integrating the padlock directly into the chain body. Designed by Auvray Security, experts for over 30 years, this all-in-one system eliminates the need for a separate padlock and radically simplifies your daily security routine, whether for traditional bicycles, electric bikes, light motorcycles or scooters.

Available variants

The C-Bloc range adapts to all your security needs through three perfectly balanced variants:

Each variant benefits from the same level of quality requirements: case-hardened steel, protective nylon sheath, integrated pick-resistant lock, 2 reversible keys and 2-year warranty.

High-resistance construction and quality materials

• Reinforced case-hardened steel: Case-hardening heat treatment providing exceptional surface hardness, proven resistance against cutting, sawing and bolt cutter attacks
• Black braided nylon sheath: Complete protection of links against weather, absorption of shocks and scratches from daily use, preservation of your bike's aesthetics and paintwork during attachment
• Anti-pick disc cylinder padlock: High-security locking mechanism directly integrated into the chain, elimination of risk of losing or forgetting a separate padlock, ultra-simplified one-handed operation
• Black and yellow color scheme: High-visibility two-tone finish, enhanced deterrent effect on potential thieves

Simplified and secure locking system

The C-Bloc concept revolutionizes the user experience thanks to its integrated padlock that locks and unlocks without having to handle a separate accessory. Supplied with 2 reversible keys (insertion possible in both directions), the system guarantees intuitive use even in low-light conditions or in the rain. The disc cylinder offers increased pick resistance compared to standard pin cylinders.
