Sustainability requires transparency – and concrete examples

What can sustainable business practices look like in practice for a mid-sized company? And do they provide economic benefits? Our fourth sustainability report provides answers – with insights into our measures, progress and practical experience.

added value in your supply chain. By the time the Digital Product Passport becomes mandatory across the EU in stages from 2027 onward, you will need to have addressed this topic.

The fourth report is now available online. It uses numerous examples to show how we implement sustainability in our day-to-day business in line with the UN’s 17 Sustainable Development Goals – from environmental measures and social responsibility to sustainable and resilient business development.

Although, as a mid-sized company, we are currently not subject to mandatory reporting requirements, we have deliberately chosen transparency. We want to show what is possible, share our experience and encourage other companies to pursue their own path towards a future-ready economy.

For us, sustainability means more than simply complying with requirements: it creates added value for our employees, is expected to pay off economically in the medium and long term, and helps us significantly reduce our dependence on fluctuating oil and gas prices.

For our customers and partners, this means working with a company that takes responsibility, operates transparently and consistently puts sustainability into practice in accordance with ESG criteria. At the same time, this approach strengthens our own resilience and long-term viability.

Our goal is clear: We want to demonstrate that sustainable business practices are possible today and inspire others to develop and implement their own solutions.

The Cyclingworld Award is entering its next round in 2027. Our founder and managing director will once again be part of the seven-member expert jury, contributing his expertise as a bicycle safety specialist.

The submission period for the Cyclingworld Award 2027 has been open since August 17, 2026. Cyclingworld Europe will take place

from March 12 to 14, 2027. Together with experts from the fields of design, sustainability, cycling, journalism and the bicycle industry, he will evaluate the submitted products and select the winners in a total of ten categories. New in 2027 is the Best Innovation category.

The focus is not limited to individual technical innovations. The award recognizes products that combine different ideas, technologies, functions and design approaches into a convincing overall solution. This holistic perspective is an important part of Dirk Zedler’s work on the jury:

“A good product can no longer stand out in just one discipline. What matters is the interplay of innovation, functionality, quality and safety in a convincing overall solution. It is precisely this multifaceted nature that makes the Cyclingworld Award what it is.”

In addition to the ten categories, the Product of the Year will once again be presented as the award’s highest distinction. The Jury Award and the Public Award are clearly separated. While the expert jury evaluates the products independently from a professional perspective, the community decides on its favorite through online voting.

There will also be a change to the awards ceremony in 2027: for the first time, the awards will be presented publicly on the first day of Cyclingworld Europe at RheinRiff.

For Dirk Zedler, serving on the jury once again provides an opportunity to contribute his many years of expertise in bicycle safety, quality and product assessment to the independent evaluation of current developments and innovations in the bicycle industry.

02:15:24: Julian Großkopf Sets a Personal Best as the Fastest Marathon Runner among German Triathletes

What an achievement: our colleague and professional triathlete Julian set a new personal best at the BMW Berlin Marathon 2026 last Sunday, once again setting a German record.

With a time of 2:15:24, he improved the German best time for a triathlete over the marathon distance – and, in doing so, broke his own record. He had only set the previous record

in December 2025 at the Valencia Marathon, when he replaced the former record holder, Steffen Justus.

In Berlin, he went even faster: with an impressive time of 2:15:24, he finished 51st overall and placed 22nd in the H age group.

Congratulations and huge respect for this impressive performance!

Oh, you test that too?

Surprisingly, around half of the respondents in our customer satisfaction survey were not familiar with our portfolio and, consequently, with the innovative range of services offered by our testing laboratory. We are therefore happy to point out that we not only conduct testing in accordance with all common bicycle standards, but have also had 43 in-house test procedures audited by the German Accreditation Body.

Our testing of bicycles, pedelecs (EPACs), cargo bikes and their components

supplements gaps in the standards and goes beyond standards whose test requirements are not sufficiently stringent. In doing so, we base our testing on the current state of science and technology.

This term is explicitly used as a requirement in the EU-wide General Product Safety Regulation, which has been binding in all EU member states since December 2024. In very practical terms, this means that the loads encountered on roads, forest tracks or trails must be replicated in the laboratory. If the average German man weighs just under 90 kilograms, testing in accordance with ISO 4210 or EN 15194 is simply not sufficient.

The same applies to a category 4 or 5 mountain bike, where the defined minimum requirements are likewise too lenient.

That is why, many years ago, we set out to close these gaps – drawing on around one hundred student theses at universities and universities of applied sciences, real-world data collected from various bicycle categories under actual riding conditions, analysis of our more than 15,000 expert reports, and extensive validation through benchmarking. We have succeeded in doing so to the highest possible level of recognition: our 43 accredited in-house test procedures.

There is also a significant knowledge gap among some of our customers regarding the components we test. Essentially, we cover the entire spectrum, from A for aluminium frames to Z for wheel truing precision.

Feel free to get in touch with our team. We are happy to put your products through their paces and help bring them to durable, fully functional series production readiness.
