Greater transparency for customers

Bosch eBike Systems supports standardised range information

  • "Standardised range test R200" enables eBike characteristics to be compared
  • Standardised process brings transparency
  • Initial tests from test institutions, DIN Spec expected by end of 2019

Stuttgart/Reutlingen – Bosch eBike Systems, working in cooperation with ZIV (Germany's bicycle industry association) and companies from the bicycle industry, has developed a standard for measuring the ranges of eBikes with defined parameters. This promotes transparency and enables comparisons to be made in the marketplace. For the first time, the "standardised range test R200" will enable manufacturers, dealers and customers to compare the range of different eBikes on an objective basis.

R200 establishes reproducible test conditions

In field tests relating to the eBike range, previous results depended heavily on the rider and the external conditions. Rider weight, tyres, air pressure, surface, weather, rider performance and behaviour cannot be reproduced in all cases, so the results are not generally comparable. That's why Bosch eBike Systems and ZIV, with support from the industry (Accell Group, Shimano, Velotech), have established "standardised range test R200". This makes it possible to compare the performance of eBikes by evaluating the bicycles on the basis of a uniform support factor of 200 percent (hence: R200). This means that the tested eBike drive system supports an average rider performance of 70 watts with 140 watts. This corresponds to a medium to high support factor.

R200 also sets values for average speed (20 kilometres per hour) and average cadence (60 rpm). Typical exemplary values are set for other factors such as weight, terrain type, surface, starting up frequency and wind conditions (see the list of requirements in the appendix). The defined parameters represent the mean real driving conditions, so the standard is as realistic as possible.

The result of the test is a specific indication of how many kilometres an electric bike will cover under these standard conditions. This result is intuitive and understandable for the customer. Most importantly: he can compare the range of different eBikes. Because of the different frame and bike specifications, manufacturers need to test each model individually using the R200 method. In addition, R200 provides information about the battery capacity and energy consumption of the eBike.

Greater transparency when purchasing an eBike

"The comparability of eBike drive systems and greater clarity when purchasing pedelecs are extremely important to us. R200 means there is now an well-based answer to the important question "How far can I get on one battery charge?" says Claus Fleischer, CEO of Bosch eBike Systems. Siegfried Neuberger, Executive Director of ZIV, adds: "eBike sales have been growing steadily for years. That's why the time had come to define a uniform standard for the transparent comparison of eBike ranges. We're convinced that the R200 test procedure will become established."

DIN Spec expected from end of 2019

The R200 is performed on qualified test benches. The operator simply has to enter the values from the list of requirements. The first manufacturers have already commissioned test institutes Velotech and the ETI at the Karlsruhe Institute of Technology to test the performance of e-bikes according to the R200 measurement method.

Bosch eBike Systems, the ZIV and the companies involved in the development of the bicycle industry are also cooperating with the German Standards Institute (DIN) in making R200 the market standard (DIN Spec). The aim is to publish the R200 in the end of 2019 as a DIN Spec and to establish it in the market. The DIN Spec can serve as the basis for a DIN standard.

The R200 makes the range of different pedelecs objectively comparable under standardised conditions. An individual range for an upcoming eBike trip using a Bosch drive system can be determined by entering personalised driving parameters with the Bosch eBike Range Assistant.

About Bosch eBike Systems

A new generation of bikes is taking town and country by storm and is already a part of everyday life. eBikes are a modern means of transport for modern people: people in a hurry and people who prefer to take it easy, the fit and the comfort lovers, commuters and pleasure cyclists and, of course, young and old. The tailwind of technology-leading eBikes made by what are already more than 70 leading brands in Europe is powered by components that Bosch is developing to perfection. The Bosch portfolio ranges from the highly efficient drive unit (motor and gearbox) and high-quality batteries to a smart on-board and cycle computer that can be used intuitively. Perfect coordination of components holds the key to typical Bosch performance in terms of both comfort and efficiency.
Like other Bosch products, the eBike systems benefit from the Bosch Group’s technology and production know-how. From conception and engineering to manufacturing, marketing and after-sales service, Bosch eBike Systems constantly set new standards for the eBike industry. The Bosch Group’s experience in the areas of electric motors, sensor technology, displays and lithium-ion batteries ensures that Bosch eBike systems use technology that is invented for life and that eBike users have their fun.
