Riding characteristics and batch quality – Accurate testing and benchmarking

Bicycles and e-bikes are on the move, often every day and on varying surfaces. Our PERFORMANCE testing systems measure their riding characteristics as well as the characteristics of individual components. They provide measurement values, such as head tube stiffness, i.e. riding stability and comfort, under comparable conditions.

As a result, you obtain from us reproducible figures of riding safety and performance including the "Stiffness-to-Weight" factor (STW), a term which was coined by us, plus precise benchmarking with products of competitors and the test results of various bicycle magazines.

In addition, we check for you with our PERFORMANCE systems, whether a production batch is of continuously high quality.

Our further SAFETY testing services in the accredited test laboratory ensure reliable tests in accordance with important standards for electric bicycles/e-bikes, bicycles and transportation/cargo bikes, such as the DIN EN ISO 4210, the DIN EN ISO 8098, the DIN EN ISO 11243, the DIN EN 15194 and the DIN 79010 standards. Where necessary and reasonable, the standards are supplemented by company-own test criteria.

These are based on our longstanding accident analyses and were verified and validated with scientific support by universities. You find a detailed list comprising the current scope of accreditation in the (German) annex tot he certificate and in the (German) internal annex to the flexible scope of application.

Siegel - das den erreichten Sicherheitslevel ausweist


We test for you on bicycle/e-bike frames and forks

  • Central frame stiffness (tracking stability for full-suspension MTBs and e-bikes)
  • Fork stiffness (steering precision, tracking stability)
  • Fork comfort
  • Riding comfort (frame elasticity, seating comfort)
  • Head tube stiffness (tracking stability, steering precision, wobbling)
  • Stiffness-to-Weight factor, (STW, constructive intelligence)
  • Bottom bracket stiffness (riding out of the saddle, frame efficiency, propulsion)
  • Coating quality

We measure for you the geometry

We test for you on bicycle and e-bike components

  • Crank stiffness
  • Wheel stiffness and overload behaviour

    in accordance with the DIN EN ISO 4210, DIN EN 15194 and DIN 79010 standards

  • Seat post stiffness (seating comfort)

We test the riding stability of e-bikes

  • Eight test criteria applied to the complete e-bike lead to the finger print making improvement potential transparent to you and classifying the e-bike as a whole.
