Hand-built in Nørrebro, Copenhagen

The cargo bike you'll keep for twenty years.

Every Lumen is welded, painted and fitted to its rider in our workshop on Mimersgade. We build forty bikes a season — each one made for the family, the trade or the dog that will ride in it.

Start with a frame.
We'll make it yours.

Each model is a proven geometry we've refined over a decade of Copenhagen winters. From there, every detail — box, drivetrain, assist, colour, fit — is specified with you at your fitting.

The workshop

Five people, one bench,
no shortcuts.

Lumen began in 2014 when frame builder Mette Lund welded a long-john for her neighbour's twins. Today five of us cut, weld, paint and assemble every bike under one roof — and the person who welds your frame is the person who hands you the keys.

01Steel, not shortcuts

Reynolds and Columbus 4130 chromoly tubing, TIG-welded and inspected joint by joint. Steel flexes, absorbs cobbles and can be repaired anywhere.

02Fitted to your body

A 45-minute fit session sets bar reach, saddle height and box position for the main rider — and a second rider if you share.

03Parts we can stand behind

Shimano, Enviolo, Bosch and Magura. Standard components, so any good bike shop in Europe can service your Lumen.

04Powder-coated in Valby

Two-layer coat with zinc primer, applied by a family-run finisher ten minutes away. Any RAL colour, no surcharge.

How a Lumen is made

Four steps from first ride to first school run.

You'll know exactly where your bike is at every stage. We send photos from the bench, and you pay the balance only when you've ridden the finished bike and are happy with it.

Ridden daily, through every Danish season.

We don't pay for reviews and we don't edit them. These are owners who agreed to let us share what they wrote after their one-year service.

“We sold our car four months after picking up the Havn. Three years, two kids and one very large Christmas tree later, it still feels like the best money we've spent.”

Two free annual services and priority repairs, usually same day in Copenhagen.

Questions

Before you spend four thousand euros.

It's a serious purchase and you should ask us anything. If it isn't answered here, call the workshop on +45 32 19 47 07 — one of the builders will pick up.

Why does a custom cargo bike cost more than a mass-produced one?

Because roughly 60 hours of skilled work go into every Lumen, in Denmark, by people paid Danish wages. In return you get a frame fitted to you, components chosen for your use rather than a price point, and a bike designed to be repaired rather than replaced. Most of our owners replace a second car — or the first one.

Can I ride before I commit?

Yes, and we'd rather you did. Test rides are free and last about an hour. Bring your children, your dog, or whatever you plan to carry. We have child seats, helmets and a 20 kg sack of flour for anyone who wants to feel a loaded box.

What if I live outside Copenhagen?

Delivery is free anywhere in Denmark. For Sweden, Germany, the Netherlands and Norway we deliver by van for a flat €290 and do the handover and fit at your door. Remote fittings by video are possible with a few measurements you take at home.

How does payment work?

A 20% deposit reserves your build slot and is fully refundable until we cut your frame tubes — we'll tell you the date in advance. The balance is due only at handover, once you've ridden the finished bike. We accept bank transfer, MobilePay and card, and offer 0% financing over 12 months.

Is it safe for children?

Every Havn and Værk box is load-tested to twice its rated payload and meets DIN 79010, the European standard for cargo bikes. Child benches include three-point harnesses, and the low centre of gravity means the bike stands securely on its centre stand while you load.

What happens if something breaks?

The frame is covered for life, components for two years, and the Bosch system per Bosch's own warranty. We use standard parts, so any competent bike shop can service it — but if you're in Copenhagen, bring it in and we'll usually fix it the same day.
