A new world of possibilities opens up for both cyclists and manufacturers. n this article, we’ll provide you with all the details and explore what composite is, how it is employed in bicycle manufacturing, and the benefits it offers.
Let’s dive in!
What is composite?
Composite (also known as “composite materials”) is an advanced material formed by combining two or more components with different properties. Typically, it consists of a matrix and reinforcements that come together to create a stronger and lighter material compared to traditional materials The reinforcements, such as carbon fibre or fibreglass, provide strength and rigidity, while the matrix, usually made of resin, provides cohesion.

And what about the bio-composite used in the Ossby GEO?
In our case, to manufacture the frame of the Ossby GEOwe use a biocomposite created from recycled fibres sourced from wind turbine blades and vegetalble resins. Let us explain:
For the matrix, vegetable resins (plant-based, our eco-friendly touch) are used, and the reinforcing material consists of fibres recycled from wind turbine blades, which are made of fibreglass.
You might wonder why we chose composite to make the frame of our new bike The answer is simple: we love challenges, we thrive on innovation, we’re passionate about all the properties and applications of composite, and we want to be more sustainable. With all this in mind, let us explain the properties of composite materials.
During the manufacturing process, an 82% reduction in carbon footprint is achieved compared to bicycles made of aluminium, fibreglass, or conventional carbon.

Applications of composite materials in the industry
Before we focus on bicycles, which is our speciality, it’s important to mention that composite materials have been used in various industries for several years, including automotive, aerospace, construction, and sports. Their versatility and ability to enhance product performance make them a preferred choice for many applications.
Why is composite ideal for the bicycle industry?
Now, let’s explore the benefits of using composite materials in the production of folding bicycles.
The use of composite materials in bicycle manufacturing has been a significant advancement in the industry.. As we discussed earlier in this article, the properties of composite materials are very interesting for bicycle production Below, we detail some key reasons why composite is our preferred choice for manufacturing our folding electric bicycle, the Ossby GEO.
Reduced weight
Composite bicycles are lighter than their steel or aluminium counterparts. This results in increased agility and portability, which is especially beneficial for urban cyclists and folding bikes. Going down the stairs at the metro or train station will no longer be a challenge 😉
Increased strength:
Composite materials are more resistant to fatigue and deformation, increasing their durability and lifespan. When creating the Ossby GEO, we wanted a bicycle that would last for many years. Did you know that composite is stronger than aluminium?
Customization and innovative design
Composite materials offer exceptional flexibility in shaping and designing components. This allows for the production of folding bicycles with unique shapes and geometries that optimize comfort and pedalling efficiency. Moreover, the ability to mould composite into complex shapes opens the door to innovative and attractive designs. Thanks to this versatility, we’ve been able to design a bicycle with clean and modern lines like our GEO.
For us, from the moment we discovered all the properties, versatility, and benefits for resource utilization and pollution reduction, we were fascinated.
Reduced vibration
Bicycles, especially folding urban bikes like the Ossby GEO, are used in urban environments where road surfaces can be uneven. Composite materials have vibration-absorbing properties that improve user comfort by reducing shocks and impacts transmitted through the bicycle. This results in a smoother and more enjoyable ride, especially on cobbled streets or uneven surfaces.
Durability and corrosion resistance
In addition to their lightweight, composite materials are extremely durable and resistant. This ensures that the folding bicycle maintains its structural integrity over time, withstanding the stresses and vibrations associated with repeated folding and unfolding.
Additionally, unlike metal bicycles, the frame of the composite bicycles do not rust and have a longer lifespan.. This is especially beneficial for those who use their bikes in humid climates or near coastal areas, as composite does not corrode or deteriorate from exposure to water and moisture.
Sustainability
Composite materials offer significant sustainability advantages, as their production is more efficient and considerably less polluting than that of traditional bicycles. During the manufacturing process, an 82% reduction in carbon footprint is achieved compared to bicycles made of aluminium, fibreglass, or conventional carbon, as it eliminates welding, which involves high energy consumption, and reduces highly polluting chemical resins and catalysts.
In the case of the Ossby GEO, the SMC (sheet moulding compound) manufacturing process allows for the creation of integrated shapes and increases sustainability by using recycled and plant-based compounds.
Therefore, a more sustainable bike is manufactured for a form of mobility that is already very respectful of the planet. This is part of our covenant and commitment.
As you can see, composite is a revolutionary material that will gradually become more prevalent in bicycle manufacturing. For us, from the moment we discovered all the properties, versatility, and benefits for resource utilization and pollution reduction, we were fascinated. We knew that our next model had to have a sustainable composite frame made in Spain. From its lightweight to its durability, design capabilities, and ease of manufacturing, composite materials raise the standard for folding bicycles, providing urban cyclists with a versatile and high-performance option.
