Hiplok D1000

A compact Diamond U-lock, sold as anti-grinder.

Sold Secure Diamond

Worth a look on high-theft streets — but only if the small U-bar will actually close.

Verdict

Worth buying if you park in a known theft hotspot, your insurance wants Diamond, and you can lock through a 92 × 155 mm gap. It is 1.9 kg with no clip to hold it on the bike. We would not buy it as a first lock for someone who already skips 1.6 kg. We have not tried to cut one. The Diamond grades are on the spec.

Best for

  • High-theft stands you have stood next to with a tape measure
  • E-bikes where the insurance names the e-bike Diamond grade
  • Riders who already know a small U-lock closes on their stand

Skip it if

  • You have not measured 92 × 155 mm and you ride a fat-tyre or cargo bike
  • You will not carry nearly 2 kg with no clip
  • Gold is enough and you want a cable in the box

This lock is sold on its anti-grinder design. It is not the easiest lock to live with. The locking area is Mini-sized — small — and it weighs more than a typical compact U-lock. Fit is the deciding factor. If the U-bar will not close around your stand and your bike, nothing else on the spec sheet matters.

Will it fit your bike stand?

92 × 155 mm is tight. Fat tyres, cargo bikes, and some UK bike stands will not take it. Hiplok’s larger DX1000 (112 × 205 mm, 2.75 kg) is a real lock, but we have not written a full review of it yet. Look at that sibling if the compact shackle is the problem, not the grade.

No clip, and it weighs 1.9 kg

There is no bike clip on the spec we have. You carry 1.9 kg in a bag, or you leave it at home. That is as important as the weight itself. For a weekday commuter whose insurance still asks for Gold, the Evolution Mini-7 is the more practical lock.

What the adverts say, and what the grade means

It is Diamond for ordinary bikes and Diamond for e-bikes. The two-cuts design story is Hiplok’s. The independent grade is Diamond. We do not print cut-times.

What’s good

  • Diamond for ordinary bikes and for e-bikes
  • Sold as anti-grinder; square U-bar is Hiplok’s two-cut design
  • 1.9 kg is heavy for a bag, but it is not a 4.9 kg chain
  • Three numbered keys listed

What’s not so good

  • 92 × 155 mm will not close on a lot of real UK stands
  • No bike clip on the spec we have
  • Heavier than the Litelok X1, for a smaller locking area

What we’d change

The DX1000 exists if you need a larger locking area. For this compact lock, a clip in the box would make it easier to take every day.

These figures come from the spec we have. If a number is missing, we leave it blank rather than guess. UK listing code B0D77XJR4Z.

Common questions

D1000 or DX1000?

D1000: 92 × 155 mm locking area, 1.9 kg. DX1000: 112 × 205 mm, 2.75 kg. Buy the one that closes. Do not guess. We have not written a full review of the DX1000 yet.

Gold or Diamond for this street?

Gold is what many UK home policies still ask for. Diamond is the higher bike grade. Read the wording you signed. We are not your insurance broker.

Does it include a cable?

Not on this listing. The U-lock is the graded product. A cable is a second, usually ungraded, extra.
