Have you ever had trouble finding a bike that fits you, or felt that the proportions of a bike you’d already set up just didn’t quite feel right? With a custom build, we can accurately measure your body dimensions and use those numbers to fine-tune the geometry, size, and proportions—creating a bike tailored exclusively for you that fits your body and riding style perfectly.

Choosing a custom, handmade bike crafted just for you—one that’s the result of time and passion—will deepen your attachment to and connection with your bike even further. It’s no exaggeration to say that for cyclists who purchase a custom bike, it’s almost certain to be a bike they’ll ride for the rest of their lives.

In today’s reality, where globalization has become overwhelming and corporate ethics often fall short of general moral standards, don’t you feel that finding people you can truly trust is becoming increasingly important?
One of the main reasons many enthusiasts turn to custom bikes is transparency and what’s known as “authenticity” (a high level of trustworthiness).By commissioning a frameset from an independent frame builder with a proven track record and history, you gain a deeper understanding of where your money is going and how it’s being spent—and you have a solid reason to confidently support what you believe in.

For example, you might have a grand plan to get a “superbike that can do anything,” but in reality, you’ll probably end up riding in just one style 95% of the time. Doesn’t it feel like a bit of a waste to sacrifice that 95% for the sake of the other 5%?

And what about materials? There are plenty of options—chromoly, titanium, carbon, stainless steel, and more. For example, if you think chromoly steel is the right material for you, be sure to listen carefully to your builder’s advice when it comes to choosing a tube set.Also, don’t forget to consider the bike’s overall balance. If you don’t have an unlimited budget, instead of choosing an extremely fancy material, why not think about how you can use your money as effectively as possible? For example, I think it’s wiser to choose chromoly over stainless steel and invest the money you save in hand-built wheels equipped with top-quality components.

This is just my personal opinion, but I think choosing a paint scheme is generally the hardest part. Since there are more endless options here than in any other aspect, you might actually just have to cross your fingers and hope for the best. But the best way to make that choice is to simply collect anything you find or like.Photos of motorcycles you find through image searches, color samples from paint manufacturers, designs from your favorite sneakers, and so on (social media platforms like Pinterest and Tumblr are perfect for this). But don’t give up—the paint shop will surely enjoy taking on your challenge with all their might.

Over the past few years, there has been a remarkable resurgence in handmade frame building, and the range of options available has definitely expanded. Builders vary in their experience, style, and methods. Building a custom bike is similar to collaborating with a shaper when creating a new surfboard—trust is especially important.

While it requires a lot of communication, the entire process should be enjoyable. That’s why it’s important to choose a builder you click with and to ensure you understand each other.

Also, not every builder can create the dream bike you’re looking for. For example, if you’re looking for a sturdy hardtail MTB, it’s not a good idea to turn to a builder who specializes in road frames—and the same goes the other way around.Some builders are known for their welding skills, others have a reputation for superb paintwork, and there are also team-based manufacturers that are highly organized and can produce the best titanium frames faster and more accurately than anyone else.

Circles has been cultivating relationships with frame builders for many years, so we have a deep understanding of each builder’s unique strengths—which means we’re confident we can introduce you to the builder who’s the perfect fit for you.

Boston, the birthplace of American culture, has been home to numerous handcrafted bicycle manufacturers throughout history, but among them, Seven Cycles stands out for its exceptional ability to produce nearly 2,000 custom titanium bikes annually, thanks to its advanced technical expertise and organizational strength.

The handcrafted custom bikes produced using their proprietary fitting method, known as “5th Element,” attract many cycling enthusiasts and are sure to guide you to the next level in your cycling journey.

A Portland-based handmade bike manufacturer for those who love riding every day, frame builder Tony Pereira—who has over 20 years of experience in designing and manufacturing custom frames—infuses his one-of-a-kind custom frames with his own unique style. Each frame is handcrafted using traditional frame-building techniques, with Columbus tubing carefully selected and positioned to suit the rider’s physique and preferences, resulting in a meticulously fine-tuned geometry design for every individual frame.
