Here you can test the new Speed-Bull!
Due to the lack of demonstrations, you can order a Speed Bull, test it and pay the rest if you keep the device. More: www.speed-bull.com
On Saturday, September 12th, 2020 we were at the first German e-MTB championship for the technical inspection of e-bikes in Daun. It was not about the performance test, but about checking at what speed the support switches off. Due to many inquiries, the procedure is explained here:
before the race, the vehicle is rolled down a simulated mountain on the testbench until it has reached 28 km/h. After the assistance has started, the driver begins to pedal. Then the speed is reduced until the assistance starts. As soon as this has been determined, the speed is checked and the measurement is ended. Vehicles that reached unauthorized high shutdown speeds (manipulations) were not detected.
The battery is hardly loaded due to the energy consumption of a few watt seconds and is the same for all e-bikes. During the measurement, e.g. an average of 200 W vehicle power measured over three seconds. This is 600 Wsec, which corresponds to 0.17 Wh. So if a battery has an energy of 400 Wh, 0.04% is required for this measurement.
Should a driver/vehicle finishes extremely quickly, it would be tested again more precisely after the race. Possibly even with controlling the sensors, wiring and checking the software for manipulation. However, this was not necessary in Daun.
Pictures will follow
Current pictures, videos and news can now also be viewed on Facebook. Here are pictures from our first fair in 2020
The first fair is the CYCLINGWORLD in Düsseldorf. From August 16th to 18th you can try out the new SPEED-Bull. Due to the current corona situation, you can register as a trade visitor.
The new founded TRAKTAL GmbH will take over all customer business in the future. The increased customer contacts through the Speed-Bull and the associated financing made this step necessary. The technical development and production will continue to be carried out by Traktal Marx e.K.. Current business, support, warranty or rental contracts remain unaffected.
