Aerodynamic Bicycle Test Facility

The ARC Aerodynamic Bike Testing Facility (ABT) provides competitive cyclists, triathletes, manufacturers of gear, clothing and bikes the advantage of increasing their speed and efficiency with the most accurate commercial bicycle testing facility. The equipment allows a range of testing with or without the rider, with six component balance resolution as accurate as 0.25 Watts.

Example test items for manufactures include:

  • Bike Frame Shape
  • Wheel Design
  • Handlebars
  • Gear Shifters
  • Clothing Materials
  • Helmet Shape

Test examples for Individual and Team Cyclists:

  • Rider Position
  • Water Bottle Placement
  • Comparison of OEM and Aftermarket Bikes and Add-ons

ABT Technical Specifications

  • Yaw capability +/- 30° during a run
  • Capacity to test with bike rolled left at 5°
  • Normal test speed 30mph - maximum 40mph
  • Six Component balance force measurement system
  • Real time data output in control room
  • Real time data output for rider irrespective of yaw angle
  • Recorded tunnel data provided in Excel compatible format
  • ANT+ compatible bike data recording
  • Wheelbases of 950mm to 1050mm can be accommodated
  • Bike can be tested with or without rider - rider pedaling or legs stationary
  • Front wheel driven independently with torque measurement of rotational wheel drag
  • Rear wheel can be driven independently with torque measurement of rotational drag, or rider driven against cadence resistance, (no wheel torque measurement)


Testing Hours

ARC's Aerodynamic Bike Test Facility is open for public use. Test sessions for 6 riders over a 12 hours day is the most cost efficient testing for cyclists. Bike fitters, let your customers know about this opportunity and increase their competitive results using state of the art tools available while keeping individual cost low.

Further your Cycling Aerodynamic Understanding Using CFD

The ARC Aerodynamic Bike Test Facility Wind Tunnel is not the only way to gain a better understanding of cycling aerodynamics. CFD (Computational Fluid Dynamics) is a digital form of aerodynamic analysis and is an excellent tool to help visualize the flow field around the bike and rider.

Most cycling CFD analysis is done using steady state turbulence modeling, which simplifies the flow field calculations using an approximation of the Reynolds Averaged Navier Stokes equations. ARC's ELEMENTS CFD software was coded and validated for transient turbulence. Transient turbulence modelling captures more of the subtle details in the airflow, as demonstrated in the video below. For more advanced analysis the effects of spinning wheels can be modeled using a sliding mesh.

The visualization images from CFD help cycling manufacturers gain a better understanding of how to improve their products, while for bike fitters to help their customers see how air is actually interacting around the body and why proper form is important.
