No. 001 — Made to order · Lead time 9–14 weeks

A cargo bike
built around your
everyday.

We’re a four-person workshop in Nørrebro, Copenhagen. We design and weld each frame to fit one rider, one route, and the children, dogs, bread, or lumber it needs to carry. Nothing leaves the door without a 200 km shakedown ride.

§ 02 — The Build

From the first coffee to the first ride: ten to fourteen weeks.

04 Steps · One welder, one frame
STEP 01

Fitting & brief

Sixty minutes at the workshop. We measure you, your cargo, your usual route, and the doorways you actually need to fit through.

Week 1
STEP 02

Geometry drawing

Mette draws the frame to scale, signs it by hand, and emails a PDF. You sign back. Nothing is welded until that signature.

Week 2–3
STEP 03

Welding & finish

Jonas cuts, TIGs and powder-coats the frame in the colour of your choice. Components sourced from Shimano, Schwalbe, Ergon.

Week 4–10
STEP 04

Shakedown & handover

A 200 km road test, brake bedding, a free first service at six months, and a folder with every torque value written down.

Week 11–14
§ 03 — The Workshop

A small shop on Jægersborggade. We make the bikes we want to ride.

04 People · 142 frames · 1 city

Jonas welds. Mette draws. Kasper tunes. Sofie keeps the books and answers your email within a working day. We are not a brand in the usual sense — we are four people, two dogs, a 90 m² workshop and a stubborn belief that a bicycle is something you should be able to walk back into the shop with, in twenty years, and have someone recognise it.

Every Lumen frame is signed and dated on the underside of the bottom bracket. We keep the build sheet on file. We will always have the parts.

§ 04 — Materials

Honest materials, chosen for the next twenty winters.

06 Components, all named

4130 chromoly steel

The main triangle. Welded by hand, air-hardened, then powder-coated. Repairable by any frame builder on earth.

Schwalbe Marathon

Plus or Pickup, depending on terrain. We size them up one level for a softer ride over cobbles.

Baltic birch ply

12 mm, void-free, linseed-oiled. Made in Riga, carried home in a friend's van. We will rebuild your box if it cracks.

Shimano, Enviolo, Bafang

You choose. Alfine 8 belt-drive for low maintenance, Enviolo for hills, Bafang M420 mid-drive for the heaviest loads.

RAL powder coat

Pick from 213 stock colours or send us a swatch. Baked at 200 °C, with anti-chip treatment on the rear triangle.

Twenty-year parts

We hold a record of every component on every bike, and we stock the spares for the lifetime of the frame.

§ 05 — On the Road

Three owners, three cities, one workshop they can name.

142 Frames · 9 countries
I sold my second car for a Lumen long-tail and have not regretted it once in four winters. It is the most considered object I own.
A Astrid · Vesterbro, KBH · MK II, 2022
They flew to Amsterdam to fit me, then came back twice for free adjustments. The bike is a decade old and rides like new.
T Thijs · Amsterdam · MK I, 2018
We move a half-tonne of bread a week on the trike. It is the quietest, calmest tool in the bakery.

§ 06 — Questions

What people ask before they book.

08 Common answers
01How much does a Lumen cost?+
From €3,890 for a Short, €4,290 for a Long Tail, €5,490 for the Trike. The final price depends on drivetrain, colour and accessories — the configurator below gives you a real number.
02How long is the wait?+
Nine to fourteen weeks from signed drawing to handover. We do not start welding until week three or four, so the deposit is fully refundable right up to that point.
03Can I see one before I order?+
Yes. The workshop on Jægersborggade is open Tuesday to Saturday, 10–17. You can ride three of our demo bikes and we can fit you in the same visit. Bring your helmet and a heavy bag.
04Do you ship outside Denmark?+
Yes — assembled and personally ridden by us before crate. We have delivered to Sweden, Norway, Germany, the Netherlands, Belgium, France, the UK and Switzerland. Shipping from €280.
05What if my child outgrows the box?+
We rebuild. Baltic birch boxes are dimensioned in 40 mm increments so we can extend them; Long Tail racks can swap to a larger deck. The price is always labour-only, not parts.
06Electric or not?+
Your choice. About 70% of the bikes we ship are electric. We supply 250 W Bafang M-series mid-drives and Bosch Performance lines, both with 500–625 Wh removable batteries.
07What is the warranty?+
Ten years on the frame, two years on the drivetrain and electrics, lifetime on the bearings. Free annual service for the first three years, then a flat €95.
08Why no online checkout?+
Because the bike is wrong if it is not measured. We would rather lose a sale than ship a frame that does not fit you, your cargo, or the door to your building.
