Diamond-rated security in a wearable, commuter-friendly form
The Hiplok DX is a compact, high-security U-lock designed for cyclists who want maximum protection without the bulk of traditional D-locks. Built around a 14mm hardened steel shackle with dual locking bolts, it’s rated Sold Secure Diamond—the highest level of bicycle lock certification in the UK.
Where it truly stands out is in day-to-day usability. With an integrated CLIP + RIDE™ system, the DX attaches directly to your belt or backpack strap, eliminating the need for frame mounts or rattling brackets. If you’re a commuter or city cyclist who wants real-world theft protection without compromise, the DX is worth a serious look.

Build Quality & First Impressions
The first thing you’ll notice is how substantial yet manageable the DX feels. The 14mm steel shackle has a reassuring heft without feeling overbuilt. It’s protected by a smooth, low-profile casing with minimal branding—a bonus if you prefer your setup low-key.
The locking mechanism is buttery and clean, aided by an internal anti-dust cover that protects the key barrel. You get three coded keys and a coded tag, making replacements straightforward.
This isn’t just a heavy-duty lock—it’s a carefully considered product built for daily urban use.
Security & Real-World Performance
The DX doesn’t just look tough—it’s earned its Sold Secure Diamond certification, meaning it has passed some of the most rigorous attack simulations on the market.
Key Features That Boost Security:
- Double deadlocking: Locks both sides of the shackle to resist twisting and leverage attacks.
- Anti-rotation tabs: Prevent the shackle from spinning even when one side is compromised.
- Tight shackle tolerance: Leaves little room for jacks, crowbars, or bolt cutters.
- Hardened core: Withstands angle grinder attempts longer than many compact locks.
For urban commuters locking up in high-risk areas, the DX offers the kind of security usually reserved for much heavier chains and full-size U-locks.
Portability & Wearability
Here’s where the DX outperforms most high-security locks: it’s designed to be worn.
The CLIP + RIDE system lets you secure the lock to your:
- Waistband or belt
- Messenger bag or backpack strap
- Saddlebag or pannier loops
During testing, the lock stayed stable and rattle-free when clipped to a backpack strap—even over cobbled urban streets. It’s less ideal for off-road riding or aggressive commuting (the occasional curb hop will jostle it), but for standard city routes, it’s genuinely unobtrusive.
If you prefer frame mounting, consider the Hiplok DXF, which includes a bracket for fixed storage.
Ease of Use
- Key barrel feels smooth and consistent, even in cold or damp weather.
- Locking/unlocking takes just seconds, making it convenient for quick stops.
- Internal clearance (15 × 8.5 cm) is enough for securing a frame and one wheel to most Sheffield stands.
- Soft-touch finish protects paint and is easy to grip with gloves.
If you often park your bike outside cafés, stations, or work, the DX is efficient enough to lock and go without fiddling or frustration.

It’s not a touring lock for front panniers and trailers, but it’s perfect for day-to-day use in bike lanes, cities, and multi-modal commuting setups.
