What We Do

We build custom bike frames out of Potsdam, Germany, and also offer a frame building course where you can learn how to build your own frame.

Frame Builder

Big Forest Frameworks offers custom handmade frames from the highest quality steel Reynolds and Columbus have to offer. With an emphasis on simplicity and beauty, and a taste for detail and design, a hand made frame from Big Forest Frameworks is something you will be enjoying for many years to come. The lightweight tube sets from Reynolds and Columbus, combined with the right bike fit for your body and riding style, allow us to produce frames that are not only lightweight, but also durable and feel great on the road or trail.


Dreaming of building your own frame? I can show you how. Sign up for one of our frame building courses and I can help your dreams to become reality. Don't think you can do it? You can. Never held a torch in your hand before? No problem. Tired of sitting in front of the computer all day and want to do something with your hands? So were we. You can do it, and it doesn't matter if you don't have any experience in the workshop. Since Big Forest Frameworks started offering frame building courses, many people just like you have already built their own frames and are enjoying riding them.
