Bike theft has evolved. Today, angle grinders are the tool of choice for professional thieves, capable of cutting through standard D-locks and chains in seconds. If you ride a valuable bicycle or e-bike, traditional locks are no longer enough.
Anti-angle grinder locks are designed to dramatically slow, disrupt and deter these attacks. They don’t make theft impossible - but they make it noisy, time-consuming and risky, which is often enough to force thieves to move on.
At On Your Bike, we focus on proven, real-world solutions for bicycles and e-bikes. Below we break down the leading anti-angle grinder products, explain who they’re for, and outline the advantages and trade-offs.
OnGuard RockSolid U-Lock (8590) - Portable Bike Security
The OnGuard RockSolid U-Lock (8590) is designed specifically for cyclists who want maximum protection in a portable format.
Using a proprietary blend of ultra-high-strength materials and a multi-layered internal structure, RockSolid is engineered to resist sustained angle grinder attacks. The hardened, shrouded shackle prevents clean cutting angles, rapidly wearing out discs and increasing attack time.
Why cyclists choose RockSolid
Size: 90 × 175 mm
Pros
Cons
Best for: Daily commuters, city riders and cyclists needing serious protection away from home.
Hiplok Anti-Angle Grinder Bike Security (1000 Series)
The Hiplok 1000 Series was created specifically to combat angle grinder theft using advanced composite materials that destroy cutting discs rather than slice cleanly.
Hiplok D1000 - The Original Anti-Grinder Bike Lock
The D1000 was the world’s first portable anti-angle grinder bike lock and remains a benchmark.
Key features
Pros
Cons
Best for: High-value bikes and e-bikes locked in public spaces.
Hiplok DX1000 – Larger D-Lock for Bigger Bikes
The DX1000 builds on the D1000 with a larger internal locking area, making it easier to secure bulky frames, cargo bikes or awkward street furniture.
Pros
Cons
Best for: Cargo bikes, larger e-bikes, or riders wanting extra flexibility.
Anchors for Home Bike Security
For many cyclists, the biggest theft risk is at home—sheds, garages and communal bike storage. Anchors allow you to lock the bike itself, not just a wheel or frame.
Hiplok AX1000 – Ultimate Home Bike Anchor
The AX1000 combines a 360° rotating base with a 180° pivoting arm, letting you secure bikes easily without chains when paired with a D1000 or DX1000.
