FAQs — FERN & ALLYGN

I build custom steel bicycles in Berlin, with a focus on fast touring, all-road riding and randonneuring. Each project starts with the rider, the intended journeys and the details that make a bicycle feel right.

Send me an email with your first ideas for your dream bike. Tell me a little about yourself, the riding you enjoy and what you would like your new bicycle to do for you.

If your ideas fit the kind of bicycles I build, we’ll arrange an initial phone call or a first short meeting at the workshop to discuss your project in more detail. Afterwards, you’ll receive an initial concept and a rough quotation for your possible new FERN.

If we both decide to go ahead, we’ll spend a full day together in the workshop. I’ll look at your current bicycles and riding position, and you’ll have the chance to test ride all the FERN bikes available at the shop. We’ll also do an in-house bike fitting session on our Calfee sizing machine and talk through literally every part and bolt of your new bicycle.

We can also arrange a visit to our painter at Velociao to explore your paint ideas, and a conversation with Kristin from Gramm Tourpacking about custom bags and how to make them work perfectly with your build.

These details are part of the conversation. We work through the complete build together, considering how the bicycle will be used and how the parts fit together. We work with Gramm Tourpacking to create perfectly fitting bags, and with Velociao, Wide Ways and Jacek Orlowski for paint. You can explore previous projects in the Bicycle Archive for inspiration.

A complete custom FERN bicycle normally costs between €7,000 and €15,000, depending on the build and specification. Timing depends on the project and workshop schedule. Please contact me for a current quotation and an indication of availability before making plans around a delivery date.

Generally, I only carry out repairs on FERN frames. However, I may be able to put you in touch with one of my framebuilding friends who can help. Send me a few details about your frame and the problem.

No, we are not a regular bike shop and do not offer general bicycle repairs. For servicing and repairs, please take a look at the bike shops listed under Partner Companies.

We usually work Monday to Friday, from 10:00 to 18:00. Workshop visits are by appointment only. Please call or send us an email before your visit so we can arrange a suitable time.

No. ALLYGN grew out of the FERN workshop so that other riders and framebuilders could use the parts on their own bicycles. Compatibility depends on the individual component and bicycle.

Start with the technical product information and the manual for the exact model. Check the mounting points, dimensions and stated limits. If anything is unclear, send us the details of your bicycle before ordering.

Visit Downloads / Manuals for the available product manuals. Read the complete instructions before installation and use. The product-specific instructions take priority over general information here.

Yes. Professional framebuilders and dealers can apply for trade access. We review applications personally and connect approved accounts with their agreed trade conditions.
