Maximum Testing Accuracy on State-of-the-art Test Rigs

Prüfstände mit höchster Prüfgenauigkeit am Beispiel "eRig" - The Latest State of the Art

Cutting-edge Test Rigs – velotech "eRig" for example - The Latest State of the Art 

The Best Dynamometer on the Market


A new level of performance measurements on Pedelecs – eRig determines the performance of electrically power assisted bicycles with unprecedented precision.
A total of three high-precision torque transducers guarantee maximum measuring accuracy. Velocity, torque and power output can be determined on cranks as well as on front wheel and rear wheel. Measuring inaccuracy is reduced to an absolute minimum. eRig provides reliable test results based on tried and tested technology in accordance with the latest industrial standards.
eRig removes analytical guesswork by way of motor characteristics! Enjoy the clear advantages of eRig over the techniques employed by other laboratories.
velotech.de stands for reliable measurements and maximum reproducibility of results!
All types of electric drive systems, whether front hub, rear hub or centre motors, and even Pedelecs with several motors can be tested on the eRig. All types of single-track bicycles, whether it be an electric mountain, cargo or compact bike, can be run on the eRig with its adjustable wheelbase of 60 to 190 cm. We can simulate numerous operating conditions up to complete load cycles by means of our specially developed cutting-edge control. Comparison with on-road measurements has so far shown extremely close correspondence with simulation on the eRig.
Two independent temperature sensors plus high-precision ammeters and voltmeters can determine additional parameters of the Pedelec in the course of the entire test. Sophisticated mechanics allow test speeds up to 50 km/h (31 mph), so that even Speed-Pedelecs can be tested on the eRig.
How many miles will your Pedelec travel up a high alpine road?
How far will you be able to ride it on a leisurely tour along a river?
eRig provides reliable answers!
