Introducing Päcker: The Eco-Conscious, Convertible Bike Trailer Transforming Urban Mobility


Urban mobility is on the cusp of a sustainable revolution with the introduction of Päcker, an innovative 3D printed convertible bike trailer. Päcker is more than just a bike accessory; it’s a versatile, eco-friendly solution for the conscious urban dweller. Let’s explore the unique attributes that set Päcker apart in the realm of urban transportation.

The Convertible Design:

Päcker is a masterclass in functionality and design. It seamlessly transitions from a stylish bike trailer to a robust sack cart, capable of handling up to 300kg of load. This transformation caters to a variety of urban needs, from shopping expeditions to aiding friends in relocating. Its universal compatibility with different bike sizes and tool-free attachment mechanism underscores its versatility.

Security Meets Convenience:

Päcker is designed with urban challenges in mind, particularly the issue of accessory theft. Its secure design offers peace of mind to users while they shop or manage errands, ensuring that their investment remains safe.

Cost-Effective and Environmentally Friendly:

Päcker stands out as an affordable alternative to traditional cargo bikes. Weighing only 8kg, it is significantly lighter than the usual 60kg cargo bikes, making it an ideal choice for urban settings with limited storage space. By choosing Päcker, users are not just saving money; they’re actively contributing to reducing carbon emissions.

Adaptable and User-Centric:

From carrying standard IKEA boxes to accommodating unusual luggage shapes, Päcker’s adaptability is unmatched. Its modular design philosophy emphasizes customer needs, allowing for future feature enhancements and upgrades.

Revolutionary Production Philosophy:

At the heart of Päcker’s design is a commitment to sustainability. Embracing a decentralized production model, Päcker uses only recycled filaments for its 3D printing process. This approach not only reduces waste but also ensures the easy availability and replacement of parts, aligning with our vision of a sustainable future.

The Future of Päcker:

Päcker continues to evolve, with plans for a digital metrics module, a motor and brake module, and a super heavy upgrade kit in development. These enhancements promise to elevate the Päcker experience, reinforcing its position as a leader in sustainable urban transport solutions.


Päcker is more than just a bike trailer; it’s a statement of eco-conscious mobility. By blending innovative design with environmentally responsible production practices, Päcker is setting a new standard in the urban transport landscape. As our cities grow greener, Päcker leads the way, showing that functionality and sustainability can indeed go hand in hand.

Embrace the Päcker lifestyle and be a part of this urban mobility revolution!
