Fit for Purpose
No two riders are alike. We measure, discuss, and prototype until the geometry matches your body, your cargo, and your daily route.
Copenhagen Workshop · Since 2019
Cargo bikes built
for your life
Every Lumen starts as a conversation. We design, weld, and assemble each bike by hand in our Copenhagen workshop — tailored to how you move, what you carry, and where you ride.
Payload200 kg
Range120 km
Warranty10 Years
Three principles guide every build
We don't build for the showroom. We build for the streets of Copenhagen — and wherever life takes you.
Materials That Last
Columbus Life tubing, stainless hardware, powder coat inside and out. Every component chosen to survive Danish winters and decades of use.
Service for Life
Your Lumen leaves with a 10-year frame warranty and lifetime access to our workshop. We're here for every adjustment, repair, and upgrade.
From conversation to Copenhagen streets
Four steps. Zero compromise. Your bike ships ready to ride.
Consultation
We meet — in our workshop or via video — to understand your routes, loads, and preferences. You'll leave with a geometry sheet and build spec.
Design & Quote
We model your frame in CAD, select components, and present a fixed price. No surprises. Approve the render, and we order tubing.
Hand-Built in Copenhagen
Each frame is mitered, TIG-welded, heat-treated, and powder-coated in our workshop. Assembly takes two weeks — one mechanic, one bike.
Delivery & First Ride
We hand over your Lumen with a fit session, maintenance walkthrough, and your first service booked. Then you ride.
Three platforms. Infinite configurations.
Every model is a foundation. You choose drivetrain, assist, colors, and cargo layout.

"The Long replaced our second car. School runs, grocery hauls, weekend trips to the summer house — it handles all of it. The linked steering took one ride to feel natural."

"I needed something that fits in my building's elevator but carries lighting kits. The Compact with a custom rack system is perfect. The ride quality surprises me every time."

"Delivering 80 kg of sourdough three times a week. The Front's platform is rock solid at speed, and the Bosch motor makes hills feel flat. Best business investment I've made."
