Zedler testing: State-of-the-art bicycle and e-bike testing technology

The safety of your products is our main concern. For this reason we have developed, built and sold our test stands since 1994 and optimized them continuously. With precise, innovative and reliable testing systems we offer tailor-made solutions for nearly all requirements of modern mechanical bicycle, e-bike and bicycle component testing. For years now we have not only been among the leading providers of testing services, but also supplying the laboratories of trendsetting bicycle manufacturers and magazines, such as TOUR, BIKE or E-BIKE, with testing systems.

You as bicycle manufacturer and importer have the considerable advantage of already knowing in advance how customers will feel about new bicycle frames, forks and other components and how bicycle magazines will mark them, especially when they use similar testing methods. This saves you from unpleasant or even legally relevant surprises, as you can modify and optimize your product at prototype stage already.

Zedler-Testing: Fahrrad und E-Bike-Prüftechnik auf höchstem Niveau


Fatigue strength and thus safety for your bicycles and bicycle components – that’s what you obtain with our SAFETY tests.


Turning riding characteristics into reliable figures – that's what our PERFORMANCE testing systems do.


Our QUALITY tests offer facts regarding precision and component compatibility.

6 reasons for testing at Zedler-Institut

Pioneers in testing technology for more than 20 years

From the very beginning our testing technology has set milestones in the processes of improving the bicycle. In doing so we do not only test, but continuously check and further develop our methods and test stands in accordance with scientific findings.

Failure in the field as benchmark for laboratory tests

The wealth of experience from thousands of expert reports and the analyses of bicycle damage is reflected in our realistic testing systems and test methods. Possible defect scenarios which would remain undetected with tests in accordance with the standard are included in our complementary tests.

Objective and documented measurement results

We do not send our test riders on the road or off-road, but bring reality into the laboratory. This is how we can test your products objectively under realistic conditions.

Scientific (further) development of test methods

We work with comprehensive scientific know-how which is not only ensured by the recognized company founder Dirk Zedler with his team of engineers, but also by permanent cooperations with universities and associations.

Tailor-made solutions for nearly all test requirements

With our modern, mechanical test procedures we are able to simulate nearly any situation typical for bicycles. In the intensity from standard requirements via typical processes in a bicycle service life to alternating extreme loads. This does not only apply to component combinations, but also to individual components.

Reliability and predictability

For years now we have been one of the leading providers of testing services. We not only equip the laboratories of trendsetting bicycle manufacturers, but also the test labs of leading bicycle magazines, such as TOUR, BIKE, Trekkingbike or E-BIKE. You can therefore check already during product development whether your bicycle or component will do fine on the market.
