The Bike Valley wind tunnel is a unique, independent, low speed wind tunnel designed specifically for cyclists and the cycling industry, where aerodynamic drag and turbulence can be measured for manufacturers, product developers, and athletes. A purpose-built wind tunnel can lead to higher overall accuracy and repeatability than the those built for aeronautics, aviation, motorsports, or other scientific research.

Facts & figures

  • Open circuit wind tunnel (~50m in length)
  • Maximum wind speed 30m/s (108km/h)
  • Test section 2.5m x 2.5m x 6.5m (two cyclists in succession can be tested)
  • Wind tunnel design allows for high level of laminar flow, which leads to very accurate and repeatable results
  • Test platform easily accessible for subjects as well as analysts
  • Possibility to shield test platform for confidentiality reasons
