Trunke

Trunke

Compact cargo bike

Introducing the Trunke, a compact and innovative cargo bike designed for maximum convenience and practicality. Our unique design combines the crankset and rear wheel, resulting in a shorter overall bike while maintaining the cargo capacity of traditional cargo bikes. This makes it easy to transport on trains, in elevators, and of course, to ride comfortably.

The crankset and rear wheel are not fixed together, allowing the crankset to spin within the wheel, and drive (with the left side chain) a secondary axle. And this one acts as the conventional crankset with the chain on the right side.

Although we have not yet created a prototype, we are excited to share our design as Open Source for anyone to use and develop. If you’re interested in exploring the Trunke and collaborating with us to bring it to life, please feel free to contact us. We’re looking forward to working together on this exciting project!

We believe in the power of collaboration and encourage makers, cooperatives, technical schools, NGOs, and companies to build upon our design. We´ll make parts list, files package and all the necessary information available on Wikifactory, a social platform for collaborative product development where you can also share feedback, contribute, and collaborate.
