What if your next bike isn't bought, but built?

From steel tubes, fire, files, and your own hands.

At Big Forest Frameworks, you build your own bicycle frame: made to fit your body, your riding style, and your story.

What you end up with isn’t a mass-produced product.

It’s a frame you built yourself.

And every time you get on your bike, you think:

I built this bike myself.

Isabell, Doctor

Not perfect, but it's mine.

As a doctor, Isabell spends her days saving lives.

Sometimes her work consumes her.

So she took a week to make something entirely her own.

Robert, Software Developer

Out of the office, into the shop.

Robert is a software developer. His days are spent in front of a screen.

But he couldn’t shake the idea of building something with his own hands.

So he traded the keyboard for a torch.

Frank, Managing Director

Just the beginning.

Frank came to the course to build his first frame.

He already knew it wouldn’t be his last.

Today, framebuilding is part of his life.

Your own bike.

Your frame is made for you. By you.
Built around your body and the way you want to ride.
A bike that’s unmistakably yours.
And the feeling of riding something truly your own.

It’s not rocket science.

You’ll cut, file and braze steel.
Most people start with no experience at all.
You learn by doing.
That’s how more than 600 frames have been built in our courses.

Real steel.

Steel is the most approachable material for building bicycle frames.

Durable.
Repairable.
Timeless.

You work with steel tubes, files and fire.

Tube by tube, your frame takes shape.

You learn each step of the process
and how to work with the tools and materials.

At your own pace, with time to focus.

Even if you’ve never done anything like this before.

And at the end, you hold your frame in your hands. Your own.

How it works

You start with an idea for your frame. Using the workbook, you develop the geometry and concept.

Questions are answered and the details are refined step by step.

Then the building begins.

You align the tubes, fit the joints and braze your frame together piece by piece.

The focus is on hands-on work. You learn by doing.

At your own pace.
With time and focus.

This is how your frame takes shape.

Built at Big Forest Frameworks

You won't find your dream bike in a store.

Or in an online shop.

Nobody has reviewed it. Nobody has even ridden it. You have to build it yourself.

Want to build at home, at your own pace, with your own tools? Or join us in Germany, just outside of Berlin, for a week you’ll never forget.
