Rat der Formgebung, Frankfurt a.M., Germany

"When I learned to ride a bike at the age of six, I also learned from my father and brother how to repair your bike yourself, not just a hole in the tube. To this day, this is a matter of course for me. Each tube has at least four patches. Only when very special expensive tools are needed I go to a bicycle workshop. That repairing has to be "reinvented" today; yes, you have to.

As a product development engineer, I know all too well that repairing is not worthwhile in most cases from a purely economic point of view. But today you have to take sustainability into account. If a bicycle repair shop were to do this itself in the specific case of a bicycle tube, it would indeed be more expensive for the customer than a new one, given our wage costs for a single inner tube. Consequently, new ideas are needed. Daniela and Nikolaj Mosch searched for and found them with reTube. I can only welcome that. Many customers have their old bicycles repaired. Therefore, there is a good chance that the idea of patched hoses will also be accepted by customers. I wish them every success."

Claus Schul, professor for product development, Darmstadt, Germany

"Together with Nikolaj Mosch, I have launched a sustainably oriented bottom bracket, which is part of the award-winning SAYA bicycle concept. The cooperation was at eye level, uncomplicated and low-cost. Mosch's concise ideas fit in with our future-oriented strategy, which focuses on people and nature. Companies will not be able to avoid going in this direction as well."

Alfred Thun, CEO Alfred Thun GmbH, Ennepetal, Germany

"Anything we can do from within the bicycle industry, to promote the circular use of our products and materials, aligns cycling with the environmentally sound ideals we strive for. The simple re-use of a repairable product such as the humble bicycle tube, that would otherwise go to landfill, is a simple, meaningful action. Add to this the social impact of providing a purposeful project for community groups and this becomes a meaningful action with real outcomes." 

Adam Townsend, Bike Matrix, New Zealand

"In the bicycle world, there is a lot of talk about "sustainability" - but only a few really tackle the topic honestly. One person who does this in a totally likeable and authentic way is Nikolaj Mosch. He is convinced that most of the solutions for a sustainable bicycle industry already exist – we just have to "dare" to tackle them. His latest project shows what such a solution can look like: His "reTube" bicycle tubes are not laboriously reproduced – instead, he repairs defective specimens in cooperation with a social project. These come back to retailers with a warranty and cool patches. A green future can look that simple! More of this, please."

Martin Donat, lifeCYCLE Magazin, Germany


"I got to know Nikolaj as part of my scientific study on the topic of increasing circularity in the bicycle industry and admire his commitment to moving from talk to action with ingenuity and entrepreneurial spirit on the topic of circular economy. Repairing inner tubes first instead of recycling them immediately saves resources. I'm keeping my fingers crossed that the concept will prove itself in practice and scale!"

Arne von Hofe (MBA Sustainability Management), Bonn, Germany


"The concept of reTube combines the old knowledge that something can be repaired with the acceptance that a full-fledged product is available again afterwards. I think the approach of keeping products in the cycle longer is very important for bicycles. At the moment, it feels like only cycling itself is the sustainable thing about cycling. Design, production, service and repair hardly come close to the good image of the bicycle."

Eric Bahr, Kinteticworks GmbH, Lübeck, Germany


Even before the German Design Award was published, the organizer of the world's oldest award, the "Good Award", wrote us a personal letter. They told us that it was time for a new understanding of design that takes up the global challenges of our time and solves them from multiple perspectives. They invited us to participate in the "Green Good Award Program". 

Thank you for trusting us as a mini-player to provide solutions to our global crises!
