01 — The beds

One frame. Three ways to carry.

Every bed is made to order — length, wood, paint. These are starting points.

Lumen 1 · 80 cm bed — Trade

Flat bed

For everything that refuses a box: planks, plants, crates, a very calm dog. Oak platform with cleats, 80 × 60 cm.

From€3,400

Lumen 1 · 72 cm box — Family

Low box

The daily default. Birch plywood with a 3 mm steel rim. Two kids, one dog, nine bags of groceries — still upright at a standstill.

From€4,050

Lumen 1 · 90 cm crate — Trade

Tall crate

40 cm of side wall and a lockable lid. Plumbers, florists, cheesemongers, marketeers. 26 kg empty, 200 kg rated.

From€4,350

Bed length, wood and paint are all made to order — the conversation decides, not the catalogue.

02 — The process

Four steps. No showroom, no pressure.

From first call to handover: about thirteen weeks. We take six bikes at a time — a queue we can actually serve.

01Week 0

The conversation

Forty-five minutes at the workshop or on a call. What you carry, where you park, who rides. We measure your cargo, not just your inseam.

02Week 1

The drawing

You receive a technical drawing and a written quote within five working days. Change anything — before we cut steel, it costs nothing.

03Weeks 2–12

The build

Reynolds 725 frame, TIG-welded in Refshaleøen. Painted, assembled, tuned. You get photos at every stage — brazing day included.

04Week 13

The handover

Ninety minutes of fitting, a ride through the neighbourhood, and your first service at 500 km — on us. Then: fifteen years of errands.

03 — Components

Parts you can pronounce, from suppliers we can phone.

No proprietary mystery parts. Everything on a Lumen is standard, stocked and serviceable — by us, by your local mechanic, or by you, with a hex key and an afternoon.

No planned obsolescence.
If we stop making bikes tomorrow,
your bike still gets serviced.

    05 — The workshop

    Two people, one welding bay, eleven years in.

    “We started Lumen because we couldn't find a cargo bike we'd trust with our own children. So we learned to weld.”

    Mads & Sofie — founders

    Lumen Cycles is a two-person workshop on Refshaleøen, the former shipyard island in Copenhagen harbour. We build six cargo bikes at a time — never more — and we answer the phone ourselves. Every frame is drawn, welded, painted and assembled forty metres from where you collect it.

    06 — On the road

    512 bikes. Here's what their riders say.

    Unedited, from our service book and the odd coffee. Names shortened for Danish modesty.

    “It swallowed the school run, the weekly shop and my catering boxes. Three years, 9,000 kilometres, one service visit.”
    KHKasper H.Valby · Lumen 1, low box
    “The drawing stage sold us. They questioned every assumption before cutting steel. I've never owned anything so considered.”
