Custom cargo bikes, Copenhagen
A cargo bike built around your love, not around a catalogue.
Lumen Cycles is a four-person workshop in Vesterbro that designs and builds steel cargo bikes to order. Every frame is measured to the people who will ride it, priced openly, and delivered with a frame that will still look right in your garage in fifteen years.
How it works
Four steps, about ten weeks, no design leave.
Most builders want a deposit before they ask a single question. We ask first.
You come to the workshop, or we come to you. We measure everyone who will ride it, list the weight you actually carry, and sketch a frame layout in the same afternoon.
60 minutesWithin four working days you get a drawing, a component list and a fixed price. If you want changes, you see the cost before we cut any tubing.
No surprisesBefore it leaves the workshop, the completed bike is tested under its final load on our rig, then ridden by one of us for three full days.
48-hour test rideDelivered assembled, with keys, documentation, a first-service kit and a walk-through of every adjustment you will want to know in winter.
Remote? We deliver nationwideWho builds your bike
We chose Copenhagen, and we chose to stay small.
Lumen Cycles began in a rented bay in Vesterbro in 2014 with two builders and one drawing board. We are still under five people, still working in the same street, and still welding every frame that leaves the door ourselves.
The work is deliberately narrow: steel cargo bikes for families, shops and organisations that will actually use the bike every day, in all weathers. That narrowness is why we can answer the phone, meet you on site, and still be signing off each frame by hand three years running.

Questions
The things people ask before they sign.
If yours is missing, write to us — most questions we have not answered here are ones we have already answered by hand.
Are these the prices I will actually pay?
The Lumen Fleter range starts at 4,000 kr. for the frame plus the components listed at that price — a mid-drive motor, battery, four-pole near-silent hubless front hub, disc brakes, lights, and a waxed cotton cargo deck sized to four seats. Custom geometry, a longer wheelbase, a second child seat, or a larger battery is quoted on top, in writing, before we cut any tube. We do not charge design fees, and we do not add an assembly surcharge for work we do ourselves in the same workshop.
What if I need it sooner than twelve weeks?
We can sometimes produce a build in eight weeks if your specification matches a finished frame layout we already hold. Rush builds are quoted at cost plus twenty percent, with the caveat that we never promise a date we cannot meet — we would rather tell you it is ten weeks than promise eight and deliver twelve. Write with your deadline and we will tell you honestly whether it is achievable.
Do you take deposits, and when?
A deposit of 1,200 kr. is taken at the signing of the frame agreement and covers the time spent drawing and reserving a slot on the build schedule. The balance is due two weeks before handover. If a build is cancelled by the customer after the deposit, that deposit is retained to cover materials already ordered. Cancellation by us for any reason after deposit is returned in full plus the agreed compensation.
How much can it carry, and can the battery be charged indoors?
A two-seat Lumen Fleter carries two adults up to 110 kg each plus 90 kg of cargo, about 320 kg on the road. The 750 Wh battery charges from any standard three-pin socket, takes roughly five hours at 2 A, and fits in a weatherproof charging bracket that mounts inside a normal lobby wall. We supply the bracket and a grounding instruction with every handover.
What happens if a bolt loosens on a winter morning?
You call us. The phone is answered by the person who built the bike whenever someone is in the workshop, Monday to Friday between 08:00 and 17:00. For a documented fault within the first 24 months we fix it and ship the part at our cost. Outside that window, standard repair labour is billed at 95 kr. per hour plus parts — which is usually cheaper than a taxi.
Can you deliver outside Copenhagen?
Yes. We deliver assembled across most of Denmark, and for orders outside the country we flatten-pack the frame and ship it with a pre-assembly inspection. Remote handover includes a written torque specification, a short assembly video, and a follow-up call once the bike is on the road.
How much does servicing cost, and how often?
We recommend a service twice a year, before spring and before the first cold snap. A standard service — brake bleed, bearing check, spoke and torque inspection, battery health readout — costs 350 kr. and takes about an hour. Annual service customers receive priority in the repair queue.

- Week 78 handover
"We had been renting a cargo bike for a year and a half. Lumen built ours around the way we actually load it — bags of flour on the left, the coffee machine on the right, and a ramp we designed with them. Three months in and nobody has touched the brakes. Our two-year-old still thinks the bell is the best thing in the city, which is the review we were hoping for."
Reserve a build slot
We'll hold your frame slot for fourteen days while we talk.
Choose a layout, tell us who will ride it, and we will reserve one of the build slots. If your dates do not work, we will put you on the next one instead of quietly dropping your name.
