VÆRKSTED · REFSHALEØEN · EST. 2016

Cargo bikes built to your centimetre, one at a time.

We are a six-person workshop on Refshaleøen. Every Lumen is measured to its rider, drawn, jigged, welded, painted and built up under one roof — then handed over with a torque log and a ten-year promise.

01 · THE BIKES

Three frames. One standard.

Every geometry is adjusted to your body and your cargo before we cut steel — but each model starts from a silhouette we've refined over nine years and three hundred winters.

№ 01
1 890 MM WHEELBASE
THE LONGTAIL · TWO WHEELS

Broen / the bridge

Rides like a city bike. Carries like a small van.

Our longest-running design. A stiffened rear deck takes two children, a week of groceries or a cello — while the wheelbase stays short enough to lean into corners like a normal bike. The one to choose if you want speed with your hauling.

LUMEN 2 240 MM · BOX 98 L
THE BOX TRIKE · THREE WHEELS

Kassen / the box

The school-run institution. Stable even at a standstill.

A 98-litre marine-ply box with bench seating for two, five-point harness mounts, and a parking brake that holds on Dronning Louises Bro in January. Three wheels mean it never tips when the kids lean — or when you load it with firewood.

THE FRONT LOADER · TWO WHEELS

Lad / the load

All the volume, none of the width. Couriers swear by it.

A long-john geometry with a low, 110-litre box slung ahead of the handlebar. The centre of gravity sits barely above your knees, so a full load still flicks through traffic. Our pick for delivery work, market stalls and big dogs.

03 · THE PROCESS

From tape measure
to maiden voyage.

Six stages, each signed off by the person who did it. You're welcome on the floor for all of them.

01

Measure & fit

An hour with tape, saddle and coffee. Bring whoever rides, and whatever you haul — kids, crates, the cello. We record eighteen body measurements plus your cargo profile.

≈ 1 HOURIN WORKSHOP
OR BY VIDEO
02

Drawing & sign-off

Your frame geometry is drawn to the millimetre and sent to you as a signed-off print — paint render included. Nothing is cut until you say so, in writing.

3–5 DAYSPDF SENT
FOR APPROVAL
03

Jig & weld

Reynolds 725 tubes go into jig №3, get tacked, then fully TIG-welded. The finished frame is checked for alignment on a granite surface plate — flat to 0.2 mm or it goes back.

≈ 2 WEEKSTIG · JIG №3
GRANITE QA
04

Paint & cure

Three coats of powder, 120 microns, cured at 180 °C. Chips are approved with you in daylight first — paint lies under shop lights.

5 DAYS3 COATS
120 µM
05

Build & tune

Drivetrain in, wheels trued to 0.3 mm, lights wired inside the tubes. Every bolt is torqued to spec and logged in your bike's paperwork — the torque log travels with the frame for life.

4 DAYSTORQUE-LOGGED
LIGHTS TESTED
06

First ride

Delivery day. We set the bike to you, load your actual cargo, and ride together around the harbour until it feels like yours. Rain check not available — we ride in all of it.

04 · THE WORKSHOP

Six people, three jigs,
one crane next door.

“We build three frames at a time. Never more. The moment a workshop rushes steel, you can feel it in the welds.”

05 · THE OWNERS

312 owners. Zero dealers.

Every bike leaves with our phone number on the torque log. These are notes back.

We sold our second car in March. The Kassen does school run, IKEA runs, and Saturday hot chocolate in the box. It has never once missed a morning.

ASTRID & EMIL — ISLANDS BRYGGE
KASSEN №0092 · 4 100 KM

I'm a fussy engineer. They sent the drawing before welding a single tube, and the finished bike matched it to the millimetre. That doesn't happen.

TOMAS R. — AMAGER
BROEN №0121 · 2 850 KM

Three winters, salt and all. One service a year and it looks new — the paint is furniture-grade. My neighbours think it's a vintage find.

NADIA K. — NØRREBRO
LAD №0038 · 9 600 KM

They measured my wife, me, and our crate dog separately. Loaded, it rides like a city bike. Honestly absurd for something carrying 60 kilos.

Asked across

If it isn't covered, call the workshop — whoever picks up can answer, because whoever picks up built something this week.

+45 31 44 92 07 · MAN–FRE 09–18

Eight to eleven weeks depending on drivetrain and paint — the build sheet above calculates your window live. A €250 deposit holds your slot; we never overbook the jigs, which is why there's a queue at all.

Frame and welds: ten years, transferable if you sell the bike. Components: manufacturer terms, but we handle the paperwork for you. Your first service at three months is free, and labour on warranty work is always free — even in year nine.

Fully, until the day your tubes are cut. After that it converts to materials. Life changes; we'd rather refund you than build a bike nobody wants.

That's the whole point. Sealed bearings, belt drives that shrug off salt, dynamo lights that don't care about batteries, and optional studded winter tyres. E-assist batteries are IP65-rated and live indoors overnight.

Five-point harness mounts, bench with headrests, a parking brake that holds on a slope, and geometry tested loaded to twice the rated weight. E-assisted builds are certified to EN 15194 / EPAC. We'll happily show you the test rig.

Both. 12–24 month instalments through our partner bank, and we'll put your old bike — any brand — toward the build after a ten-minute look-over. Several cargo bikes have started life here as a trade-in city bike.
