ExtraEnergy introduced a number of new facets to its pedelec and e-bike test in the Autumn 2009 Test. For instance, for the first time, specialist riders tested the tour bikes. Also for the first time, values were collected separately for city sections, in addition to the performance values for mountain and tour sections. Furthermore, laboratory test results will for the first time be taken into account in the final evaluations.
Tour bikes in test
During the measured rides in Tanna, tour bike specialists Jan Gathmann, chief editor of the magazine RADtouren, and Hans Pfeiffer, managing director of Ferrotec GmbH in Braunschweig, tested six pedelecs for how they meet the demands of touring cyclists. The following bikes were selected out of the ExtraEnergy test fleet:
BionX: PL 250 HT conversion kit
Gazelle: Orange Innergy
Hercules: E Move Sport SL Lite 2010
Hartje: Victoria Münsterland
Kalkhoff: Agattu XXL Pedelec C
Kalkhoff: Sahel Pro Disc
Kettler: Hybritec Obra
Koga Miyata: Tesla Tour
Kreidler: Vitality Pro
riese und müller: Jetstream hybrid
riese und müler: Avenue
With the ExtraEnergy measuring instruments fitted to the bikes, the two testers rode over the 5.25 km long tour section of the test track. The bikes also carried two bags, each weighing 20 kilogram. The data of the test rides were later added to the data of the regular test.
Afterwards the tour bike testers and ExtraEnergy evaluated the results of the tour section rides. The results will be published in the RADtouren magazine in April 2010 and shortly thereafter on the ExtraEnergy portal.
Until now the range and assistance factors on the mountain and tour sections were calculated and included in the test reports of bikes. The new test reports, to be published early in the spring of 2010, will also include the riding performances for the city section (range and assistance factor). Mountain, tour, city - with that the user gets all the riding performances of the most important user areas.
Laboratory tests in evaluation for first time
For the first time, the results of the laboratory tests will be included in the evaluation of the test bikes. The firm velotech.de in Schweinfurt tests the bikes for their mechanical rigidity and the SLG Prüf- und Zertifizierungs GmbH tests the electrical components for their conformity to the standards. The vital tests for the evaluation of the test bikes are the braking performance and stability of the frame.
The bikes in the Spring 2009 Test already went through these laboratory tests, to determine the state of the technology, develop a suitable test method and create the scientific foundation for the GS tests of electric vehicles.

Shorter test track
For the Autumn 2009/10 Test the test track was shortened from 18 kilometer to 14.5 kilometer, since the loop behind the town of Zollgrün didn't produce any new insights or information in the Spring 2009 Test.
