A cargo bike built around your family. Not a catalogue.

Why it costs what it costs

4,000 euros is not for a logo.
It’s for 60 hours of labour.

A mass-produced cargo bike costs less because it is designed to be replaced. Ours is designed to be repaired for a decade. Here is exactly where your money goes on a typical Havn build — before options.

Where 34,900 kr goes

Havn base build, incl. 25% Danish VAT. No hidden fees. We itemise every build before you sign.

✓ Fitted to your measurements
✓ 40 km loaded road test
✓ First service at 500 km free
✓ Lifetime geometry check
01

Built for the rider, not the average

We measure your inseam, shoulder width and the children you carry. Frame length, box height and stem are adjusted before a single tube is cut. That is why it fits — and why it holds value.

02

Materials you can service forever

Reynolds 853 steel, FSC-certified birch, Shimano and Bosch components stocked in Denmark. No proprietary batteries, no discontinued parts, no “send it back to the factory”.

03

Tested the way you will use it

Every bike leaves with 80 kg in the box. We brake hard, ride one-handed, climb Refshalebakken loaded. If something flexes or rattles, we fix it before you see it.

04

Transparent, in writing

You sign a detailed spec sheet with price, timeline and warranty before we build. Deposit is 20% and refundable for 14 days. Balance is only due at handover, after you have ridden it.

The honest maths

A 15,000 kr import bike replaced every 4 years costs 3,750 kr per year. A Lumen at 29,900 kr lasting 12+ years costs under 2,500 kr per year — and you keep the frame.

We handle the rest.

All three share the same steel, the same workshop and the same warranty. The difference is how much life you need to carry.

All motors are standard Danish-serviceable systems with local spare parts.

3 · Gears

Hub gears need no adjustment and survive Danish winters.

4 · Box finish

Panels are bolted, not glued — a damaged panel is a 20-minute fix.

5 · Extras

Only add what you will actually use. We will talk you out of the rest.

How ordering works

Seven weeks.
Six clear steps.

You will always know what is happening with your bike. We send photos from the workshop each Friday during your build.

0145 min

Consultation & test ride

Visit us or book a video call. Bring the children. We ride, measure, and talk honestly about whether a cargo bike is right for you.

02Week 1

Design & geometry

You receive a CAD mockup and a full itemised spec sheet. Nothing is ordered until you sign it. Changes are free at this stage.

03Weeks 2–4

Frame building

Your Reynolds 853 tubeset is cut, TIG-welded in a jig and checked for alignment three times. This is the heart of the bike.

04Weeks 4–6

Paint & box

Powder coating in your colour, birch box built and oiled, electronics fitted and wired. We photograph every stage for you.

05Weeks 6–7

Assembly & road test

Full assembly, then 40 km of loaded testing around Refshaleøen. Brakes, steering, shifting and rattles — fixed before handover.

06Week 7–8

Handover & first service

We fit the bike to you in person, adjust seats and box, and book your free 500 km service. Balance is due only now.

Materials & workshop

Steel, birch, and
components that last.

Reynolds 853 — why steel?

Steel flexes a little, rides quietly, and can be repaired by any good frame builder in 20 years. Aluminium and carbon cargo frames cannot. We weld every frame in-house.

TubesetReynolds 853 air-hardened steel
WeldingTIG, in a single jig, checked 3×
GeometryCustom per rider, from your measurements
Warranty10 years on frame & fork

FSC birch plywood, bolted panels

Our box is not a moulded tub you replace if it cracks. It is individual panels, oiled with linseed, bolted through a steel subframe. A scratched panel is replaced in minutes.

MaterialFSC-certified birch, 12 mm
FinishLinseed oil, re-oiled annually
Volume180 / 220 / 280 L by model
RepairsSingle panels available for 10 years

Standard parts. Local service.

We deliberately avoid exotic parts. Everything on a Lumen can be serviced by us — or any competent workshop in Denmark — with parts stocked locally.

GearsShimano Nexus 8 / Pinion 11
BrakesShimano hydraulic, cargo rated
LightingDynamo as standard, StVZO approved

Powder coat, not paint

Frames are powder coated in-house in any RAL colour. It resists chips, salt and shopping-trolley impacts far better than wet paint — and we can refinish a panel for you years later.

ColoursFull RAL chart, matte or gloss
RefinishingAvailable in workshop, from 1,800 kr

Custom geometry, explained

Every frame starts from your measurements. This is a Havn geometry for a 172 cm rider — yours will differ.

Ownership

We build it.
We look after it.

A cargo bike is a 12-year commitment. Ours is too. Every Lumen comes with a relationship, not just a receipt.

10-year frame warranty

Welding, fork and subframe. In writing, on your spec sheet, with our CVR number on it.

2-year component warranty

Motors, gears, brakes and electronics — through Danish service partners.

Free 500 km service

Chain, brakes, bolts and steering checked after you have bedded the bike in.

Lifetime geometry check

Bring it in any year. We check alignment and fit for free, as long as you own it.

“

I was nervous about the price. Then I rode the test bike with both kids and 3 kg of strawberries. It just… worked. Two years later I still text the workshop photos from our rides.

“

As a baker I need the Ø to carry 140 kg before sunrise, every day. They built it around my delivery route, not a catalogue. It has paid for itself against the van.

“

What sold us was the spec sheet. Every kr itemised, deposit refundable, and they talked us out of the motor we thought we needed. That honesty is rare.

Questions, answered plainly

Everything you are
wondering before you spend 4,000 euros.

Because we spend roughly 60 hours per bike that imports spend near zero on: custom frame building, in-house powder coating, a bolted birch box, and 40 km of loaded testing. You also get a 10-year frame warranty and a workshop that will still be here to honour it. An import bike is cheaper to buy and more expensive to own — and it is designed to be replaced, not repaired.

Currently about 7 weeks from signed design to delivery. Pinion gearboxes and custom RAL colours can add 1–2 weeks. We will give you a date in writing before you pay the deposit, and photos every Friday during your build. We build a maximum of 4 bikes at a time — we will not take more orders than we can build well.

Yes — and we insist. Book a free test ride at the workshop. You will ride a demo bike loaded, with children if you wish. There is no obligation and no sales pressure. If a cargo bike is not right for your life, we will tell you.

Yes, in full for 14 days after you sign the spec sheet, for any reason. After that, the deposit covers materials ordered for your build. The balance (80%) is only due at handover, after you have ridden your finished bike.

Bring it to Refshaleøen. We built it, so we fix it — usually within a week. Frame warranty is 10 years, components 2 years. We stock spare parts for 10 years and use only standard, Danish-serviceable components, so you are never locked into a discontinued system.

Yes. Delivery across Denmark is 1,200 kr, with a full handover video call and a local workshop check arranged for your first service. EU delivery is by arrangement — contact us and we will quote it honestly before you order.

Come and ride one.
Then decide.

The best way to understand a Lumen is to ride it loaded, in the rain if possible. Book a consultation — it is free, takes 45 minutes, and ends with coffee, not a contract.
