The ExtraEnergy Test 2001 took place in the Thuringen region of Germany. For two months, 5 riders between the ages of 22 and 65 tested 32 different pedelecs and e-bikes.
The bikes were ridden by the test crew on the “mixed track”, which is a route through the city of Tanna and surrounding landscape covering a total distance of 7,8 km. The track was comprised of flat and uneven road surfaces as well as many hills (up to a 6% grade). There were also 3 designated “stops” along the track where each rider was required to pause for a specified amount of time.
All of the pedelecs followed the same track and were ridden until the electrical assist system had stopped completely. Some pedelecs are equipped with different assist modes or are available with different batteries, so each bike was tested using all possible scenarios. When the test was completed, the ExtraEnergy Test team had accumulated several thousand kilometers on the pedelecs.
ExtraEnergy tested all of the pedelecs on two grades in the Saale Valley not far from Tanna. One grade had an average 6,3 % slope with a maximum of 8 % and the second and steeper grade had an average 8 % slope with the steepest part being 12 %.
If possible, all test riders went up both hills in a seated and relaxed fashion. The quality and amount of assistance was measured by the average speed and personal observation comments recorded by the test riders after each ride.
