The Danish bicycle company, Coh&Co Copenhagen, has a goal to bring new riding experiences, with quality and sustainability to urban cycling. That’s what brings us the Siggi foldable bicycle.

Believing that when you start a new brand, bringing your own ideas and innovations to the table, you must ask yourself, “How you can do it better?” Coh&Co was founded by Paul Harder Cohen and Mette Walsted Kristiansen. Both with backgrounds in product design and engineering are committed to bringing a wealth of design, technology, and craftsmanship to every Coh&Co product.

The inspiration for Siggi came when we realized that there are a lot of advantages to small wheels that we can also put into the urban environment without making all of the compromises that often come with it. It is born not out of a need to fold, it is born out of a need to ride.” – Paul Harder Cohen

To enhance your riding experience and everyday convenience, Coh&Co says Siggi is packed with functional features. When they designed it, they strived to create the ideal urban bicycle – a bike that provides a responsive and comfortable ride while adapting to everyday urban life.

The Siggi has 20″ wheels which help in making it easy to fold and store, making it easy to bring on a train, pack in the truck of your car, or store in your home or office.

The stout, but short top tube pulls dual purpose as a handle as well.

The bicycle’s handlebar and cockpit are also fully adjustable, making it easy to find the right fit.

The rear rack looks to serve as a rack and a stand for the Siggi when it’s folded. It even incorporates rollers to help maneuver it into position once folded.

The Siggi also has a carbon “lefty” fork, which plays a key part in keeping the total weight of the bike lower as well as aiding in Siggi’s elegant fold.

In the pictures, it looks like the Siggi will have an elastomer-based rear suspension system, as well as whatever the suspension system is on the fork. According to their website, there will be an electric Siggi available as well.

“Designing Bicycles for Life”

  • StoneWeave Frame:Siggi’s frame is made of StoneWeave, our proprietary frame material technology. It is a special blend of carbon and basalt rock. On top of being lightweight, super durable, and stiff, it is recyclable at the end of its life span”.
  • Designed in Copenhagen: “We’re called Coh&Co Copenhagen for a reason. All our designs are focused on functionality in the urban environment. We’ve designed high-quality urban bikes for 8 years already.
  • Sustainability:When buying Siggi, you’re investing in a high-quality riding experience you can enjoy for years and years. After a minimum of 10 years, we take Siggi back to either refurbish and resell it or to recycle and repurpose the frame material.
  • Sleek Aesthetics: “Siggi is not just designed with functionality in mind. We know how much looks play into how we connect with our everyday objects, which is why Siggi displays a sleek and clean design”.

I didn’t find any information on the weight, or specs of the Siggi on their website. But you can check out their Indiegogo by hitting the link below.

That front brake cable routing looks like quite a sharp bend. I imagine it’s pretty tough to get that brake to feel nice using mechanical lines.
