The cargo bike your family deserves.
Every Lumen is built to order in our Nørrebro workshop — hand-welded steel, fitted to your body, your streets, and your life. No warehouses. No compromises.
Built like it's the only one. Because it is.
One builder. One bike. From raw steel tube to your doorstep, your Lumen passes through a single pair of hands — yours truly, welded and finished by the person who answers your emails.
Hand-welded chromoly
Every frame is TIG-welded from double-butted chromoly steel. Lighter than it looks, stronger than it needs to be, and repairable forever.
Fitted to your body
You visit the workshop for a full fitting — inseam, reach, riding style. Frame geometry is adjusted to you, not the other way around.
Carries 180 kg
Two kids, a week of groceries, or both. The reinforced longjohn box and tri-rated frame handle Copenhagen's daily haul without breaking a sweat.
All-weather ready
Powder-coated beneath the paint, stainless hardware throughout, and full fenders fitted as standard. Danish rain is not an occasion — it's a Tuesday.
Lifetime service plan
First five services are on us, forever discounted after. We keep a file on your bike — every bolt, every adjustment — for as long as you ride it.
Designed for cities
Narrow enough for bike lanes, stable enough for cobblestones. Your Lumen is engineered around the streets of Copenhagen — and yours.
From conversation to cobblestones in eight weeks.
No production line, no waiting list lottery. Just a clear, honest path from your first email to the bike you'll keep for decades.
Talk
A 30-minute call or coffee at the workshop. Tell us what you carry, where you ride, and how the bike should feel.
Week 1Fit
You visit Nørrebro for a full fitting. We measure, adjust the geometry, and lock your spec — frame, box, gears, colours.
Week 2Build
Your frame is welded, painted, and assembled by one builder. You receive photo updates at every milestone.
Weeks 3–7Ride
Final setup, a test ride together, and handover. Then a lifetime of service — and the first five check-ups are free.
Week 8Serious hardware, honestly priced.
We buy the same components as the big factories — we just don't mark them up to pay for showrooms in every postcode.

Lumen Longjohn — from €4,000
That's the complete bike: your fitting, your colours, e-assist if you want it, delivery within Denmark, and the lifetime service plan. The price we quote is the price you pay.
4,000 euros, spent well.
We don't advertise. Most Lumen owners arrive because a friend wouldn't stop talking about theirs.
"We sold our car eighteen months ago. Two kids, a dog, and a weekly shop — the Lumen handles all of it. People stop me to ask about it constantly."
"As a bike mechanic myself, I'm hard to impress. The welds, the cable routing, the finish — it's workshop-quality work at a fair price. No regrets."
"The fitting session alone was worth it. They adjusted everything to my back, and six months in it still feels like it was made for me — because it was."
Your build slot is waiting.
We take on twelve builds per season so every bike gets the attention it deserves. Reserve yours with a €200 deposit — fully refundable after your first conversation.
