It doesn’t matter what you’re doing, I want you to stop it and soak in the majesty of this stainless steel full-sus Moorhuhn!

Keywords are important when it comes to writing a story. We need to use the sort of words that will not only grab the readers attention but also words that rank well on search engines. It can sometimes be tricky, but not this time.

The Huhncycles Moorhuhn has it all! 3D printed, steel, stainless steel, full-suspension, handmade! Chicken!

Stainless steel, 3D printed and handmade!

Ralf Holleis is the frame maker, engineer and artist behind Huhn Cycles, a part-time frame making business where he uses cutting edge technologies to make ‘sexy’ (his words) frames. Ralf uses his skills to build bikes and frames unlike anything we would normally see, and is a dab hand at building titanium and steel bikes, and will even use carbon fibre on some projects too.

3D Printed

Next level internal cable routing!

This latest project, the Moorhuhn, takes Ralf’s passion for technology to the next step using 3D printed steel lugs welded into Reynolds 953 steel tubing to create this absolutely stunning full-suspension frame.

Lugs for the seat tube / top tube junction, bottom bracket / main pivot and head tube are all manufactured using a 3D printed process, though others might argue that this is actually an additive manufacturing process close to what Atherton Bikes does.

Internally the lugs feature a honeycomb structure which supports hose and cable routing to keep this stainless steel stunner uncluttered once built.

Stainless Steel

We can only imagine what one of these must cost!

Reynolds 953 is a stainless steel tubing and is an extremely hard metal that is resistant to fatigue. It’s not a material that is commonly used, and we imagine it costs a pretty penny, but what price can you put on a raw stainless steel frame? If only we had a Delorean for shuttle duty!

The front triangle is made completely from 953 which is welded or silver brazed to the lugs. The rear is manufactured from Columbus Zona steel, another high-end steel which is often compared to 853.


Once all those tubes and lugs are fastened together the result is the Moorhuhn, a full-suspension bike aimed at trail riding with 129mm of rear-wheel travel.

Designed around a 140mm travel fork, the Moorhuhn has a 67-degree head angle, 76-degree seat tube angle and a reach for 469.6mm which results in a 621.6mm top tube length.


Huhn is Chicken in German. Why chicken you might ask;

“Getting dirty is fun, chickens live in the dirt, jet they look very elegant!
Chickens walk forward with their heads up high, while doing so they never loose focus.


Last but not least chickens have the skill to fly for short distances, mountain bikes do the same !”
