CUBE

Quality standard

INHOUSE TESTS

We at CUBE develop and produce premium bicycles. We strongly value the safety and quality of our products.

That’s why we offer a quality that outperforms the legal safety requirements and which complies with additional performance profiles for any special task or goal.
To make this true we have developed our own in-house testing procedure with our own protocols and test equipment. These are based on the European Standards for bicycles (for instance, EN14766 for mountainbikes, EN14781 for road bikes, etc.) and on the voluntary standard DIN-plus which exceeds EN. We test to the newest insights for which we co-operate with the technical University of Munich. The tests our bikes are submitted to go much farther than the usual business standards.

Test machinery we have specially developed for these test series enables us to test in the reality of near-to-practice simulations. We test our frames, forks, brakes and handlebar combinations on the factual stresses, loads and charges they may meet in various situations when in real use. This includes standing on the pedals, jumps and fatigue tests and front impact crashes.

In the so-called front impact test the forks and brakes are hit by a pendulum with increasing weight till it collapses (destructive testing). Simulating frontal impact like ripples on the track, jumps, crashes, etc. we can measure the loads on the front axle, the behaviour of the frame and conclude whether it matches the use it is intended for.

Our quality control includes additional tests for parts supplied to us (for instance, forks). In this case we take random samples from every batch we receive. These samples are tested on our dynamic test bench and charged and released 130,000 times, which comes to about 10,000 km on the track.

Our in-house tests are a very important part of our quality control and a tool to ensure quality in the final product. But it also gives us valuable data for product development. With our continuous quality control we can stick to a very consistent output quality standard for our products, and on the other hand we generate new knowledge for efficient product development and to increase our technological advance.

As one of six core partners in the Bike Competence Centre of the technical university of Munich (TUMbcc) we can resort on huge databases and results of the project ‘Betriebsfestigkeit in Hochleistungsfahrradbau’ (Solidity in the construction of high performance bicycles) led by dipl.-ing.Matthias Bluemel. We use their interpretation for the concepts of new bicyles. We also use these data for regular checks on the quality of series production. These measures guarantee the customer of our product the highest level of product safety.

APPRAISAL BY EXPERTS

Beside to our own test references and those of the Technical University in Munich we have all our bicycles tested by the independent test institute Velotech.de GmbH (German Website) in Schweinfurt.

All our products without exception are thoroughly tested according to DINPlus of the DIN Certco Gmbh in Berlin. Only products that meet the standards get the DIN-Plus quality mark.Velotech.de GmbH is active since 1991, it has extensively measured the forces on bicycles in daily use and in simulation, and has continuously developed new methods and hardware based on its results. Dynamic repetitive tests are performed in various steps till the product on test reaches the formulated goal, till it gives in or it collapses. For every test an entry protocol is formulated as to what special forces will be applied. The worst case and the most unexpected abuse are estimated and included in the test battery. Based on existing standards of the certification program Din-Plus and the actual state of the art, the formulated tests are performed.Velotech.de GmbH company’s motto is: ‘We test it as a whole and not only its components’.Our motto is: ‘Only after a product has passed the DIN-Plus tests it will be marketed.’
