Security & Durability

Security Features
The Hiplok D1000 Unisex Shackle Lock is built with security in mind. It uses a patented Ferosafe Graphene component, which is extremely strong and lightweight, resisting motorized attacks better than standard steel locks.
The hardened steel core and rotation-proof double locking tabs increase resistance against cutting, twisting, and prying.
Anti-Theft Technologies
The lock’s double locking mechanism and anti-rotation tabs greatly increase the time it takes for thieves to break in. Its Sold Secure Diamond certification reflects the highest level of theft resistance available for bike locks today.
How Secure Is It?
For anyone riding a best bike or an electric bike with 20×4 e-bike tires, this lock offers serious protection. Even in high-risk areas, I feel confident securing my bike with the D1000.
Built to Last? Durability & Construction
- Made from alloy steel combined with a graphene rubberized coating for weather resistance.
- Double locking tabs prevent shackle rotation, a common attack method.
- The thick shackle and lock body withstand harsh weather and physical attacks.
Materials and Construction
Shackle/Chain Material and Thickness
The shackle is crafted from hardened alloy steel reinforced with graphene rubber, providing a robust 16 mm thickness that balances strength and portability.
Lock Body Material
The lock body combines premium alloy steel and weatherproof rubber seals to protect internal mechanisms from water and dust damage.
Protective Coatings
The graphene rubberized coating guards against corrosion, making the lock suitable for all weather conditions and extending its lifespan.

The key operation is smooth most times, though sometimes the key gets stuck halfway. My tip is to push the crossbar fully before turning the key.
