Custom cargo bikes · Nørrebro, København
Lumen Cycles is a two-builder workshop in Copenhagen. We TIG-weld steel cargo bikes to your body, your route and your cargo — specified with you, signed by the builder who made it. Six to ten weeks from first fitting to first ride.
01 — The range
Every Lumen starts as one of three platforms — then we lengthen, lower, widen and re-spec it until it fits your life. No two builds leave the workshop alike.
The front-box long john. Two kids, a week of groceries, or sixty litres of almost anything — with a low, stable ride.
A longtail for school runs and light freight. Narrow enough for the cycle superhighway, strong enough for the workshop.
Small wheels, a low step-through and a big front basket. The city runabout for flats without storage and short, frequent trips.
Every Lumen · chromoly steel frame · Gates belt · hydraulic discs · 3-year frame warranty · free first service
02 — Configure
Pick what you need, see what it costs — before we ever meet. Your final quote is confirmed at the fitting, and it never changes after you approve the geometry.
Delivery within 15 km of København K included · payment in three interest-free instalments at handover
03 — The process
No sales floor, no hand-offs. The person who welds your frame is the person who fits it to you.
A 45-minute conversation: your routes, your cargo, your heights. In the workshop or by video call.
We draft your frame geometry and send a CAD sketch. Nothing is cut until you sign off.
One builder welds, files, paints and assembles your bike, start to finish.
Every bike rides 12 km through Nørrebro on our test route, then is tuned to your weight.
Handover with your first service included — and a frame passport signed by your builder.
04 — The craft
We buy from the same European suppliers as the fine frame builders, we over-specify where it matters, and we never hide a component list. Ask us anything — we answer with datasheets, not slogans.
Double-butted European chromoly, TIG-welded and stress-relieved. Rated for 250 kg gross, guaranteed for daily use.
Carbon-belt drive: 30,000 km of silent, grease-free pedalling. No chain oil on your coat, ever.
Shimano hydraulics with 180 mm rotors, bled and bedded in by hand before handover.
Eight workshop colours, mixed and cured here — or bring your own RAL for €180.
Every Lumen frame carries its number inside the down tube and on this passport. Crash it, and we inspect it free — for as long as you own it.
05 — From the street
“They asked what I carry on a Tuesday. Nobody had ever done that. Eight months in, it still feels drawn for me — because it was.”
Mette H. · Frederiksberg — bakery run, Carrier Nº 98
“Two kids, a dog, a full weekly shop. The Long has swallowed all of it for two winters without a single rattle.”
Jonas P. · Nørrebro — school run, Long Nº 212
“I compared four workshops. Lumen was the only one that showed me the geometry drawing before taking a single krone.”
Sara L. · Østerbro — commuter, Compact Nº 164
06 — The workshop
We are a working workshop, not a showroom — you will hear the saw and the grinder, and Andreas will probably offer you coffee. Fittings by appointment; walk-ins welcome Saturday mornings.
07 — Questions
Six to ten weeks from geometry sign-off. The live queue is shown when you book, and deposits are honoured strictly in order — nobody is skipped, nobody is rushed.
It reserves your place in the queue and your builder's hours. It is fully refundable until you approve the geometry drawing; after sign-off it goes toward the build price.
Three years on frame and welds, two years on electrical components, and a free annual inspection for as long as you own the bike. Crash damage is always inspected free.
Yes. Ride our demo Carrier or Long during your fitting — and your test route is your actual commute, not a loop around the block we chose.
Across the EU in an insured wooden crate from €140; delivery in Greater Copenhagen is included. Worldwide shipping is quoted per build.
08 — Book
Forty-five minutes, zero obligation. We measure, we listen, we show you the queue. If a Lumen isn't right for you, we'll tell you who built the one that is.
Andreas or Emil replies within one working day — usually faster.
Your request is logged. Andreas or Emil will reply within one working day to find your fitting time.
