Why we build to order
An off-the-shelf cargo bike was designed for an average family that doesn’t exist.
Your street is cobbled. Your cellar staircase turns twice. One child is seven, the other is a dog, and the nearest shop is 1.8 km uphill.
So we start with the frame, not the catalogue. Every Lumen begins with a measurement session — your height, your reach, your turning circle at the bottom of the stairs — and ends with a dimensioned drawing you approve before a single tube is cut.
There is no production line here. Four people, two jigs, a torch, and a build sheet with your name on it that we keep for as long as you own the bike.

The Long Haul
From 5.100 €
For the households that sold the car. Bosch Cargo Line motor, dual battery, belt drive and a full year of Copenhagen weather.

The workshop
Steel, brass
and patience.
Every joint in a Lumen frame is brazed by hand with a brass fillet, at 800 °C, one tube at a time. It is slower than TIG welding and it leaves a small, honest fillet you can see under the paint.
It also means a frame you can repair in forty years instead of replacing in ten. Steel tells you when it is tired. Aluminium just goes quiet.

How it works
Four steps. About twelve weeks. No surprises on the invoice.
01 — Conversation
We ask what you carry
Thirty minutes, in the workshop or by video. Your street, your stairs, your children, your knees. No deposit, no obligation.
02 — Drawing
A fixed quote in five days
You get a dimensioned drawing and a price that does not move. We only start cutting tubes once you have signed it off.
03 — Build
Six to nine weeks on the bench
Photos at brazing, paint and assembly. You are welcome to visit at any point — most people come twice.
04 — Handover
Fitted, then checked at 500 km
We set saddle, bars and brake levers to you in Nørrebro, then service it free once you have ridden 500 km.
Owners
What 412 bikes sound like after a few Danish winters.
We replaced a car with it. Two kids, a cello and a week of groceries, up the hill to Vanløse, in the rain. It just does it.
Sofie & Rasmus · Vanløse · School Run, 2021
Four years, 19.000 km. One chain, one set of pads, one service a year. The frame still looks like the day I collected it.
Anders K. · Islands Brygge · Hauler, 2020
They measured my daughter’s shoulders before they welded the bench. That is not a normal thing a bike shop does.
Marie · Nørrebro · School Run, 2023

Questions
The things people ask before they visit.
How long does a build actually take?
Twelve weeks is typical from deposit to collection, and fourteen if you choose a
custom RAL colour. We give you a firm week number when you sign the drawing,
and we tell you immediately if it moves.
Can I ride one before I order?
Yes. We keep two demo bikes in Nørrebro — a rigid Hauler and a Bosch-assisted
School Run. Book a slot and take one for a proper hour, ideally with your
heaviest cargo on board. Bring the kids; the harnesses are already fitted.
Do you deliver outside Denmark?
We ship anywhere in the EU, fully assembled and checked, from 180 € depending on
distance. Bikes travel in a dedicated crate and arrive ready to ride apart from
straightening the bars.
What happens in year nine when something breaks?
Every standard part on a Lumen is a standard part you can buy anywhere — Shimano,
Magura, Sapim. We keep your build sheet on file indefinitely, so we can tell you
exactly which bearing, cable or rotor went into your bike even a decade later.
What is covered by the warranty?
Five years on the frame and fork against defects and brazing failure, two years on
the powder coat, and two years on components under the manufacturer's own terms.
Wear items — pads, tyres, belts — are not covered, which is normal.
Will you electrify a cargo bike I already own?
No, and it is the only thing we always decline. Retrofitting a motor to an
unknown frame means we cannot vouch for the brakes, the dropouts or the tubes
taking that torque. We only motorise frames we have brazed ourselves.
Come by
The workshop is open Tuesday to Saturday.
No showroom, no sales desk — just the bench, the jigs and whoever is brazing that morning. Coffee is usually on. Book a slot so we can put a demo bike aside.
