Pedalling Efficiency Rig
Optimise Your Bike Setup
Discover exactly where your power is being lost with the Pedalling Efficiency Rig. It measures the power you put into the pedals and compares it to the power delivered to the rollers, giving a clear, accurate efficiency score for your complete bike and rider setup.
Quickly test and optimise real-world factors like tyre pressure, wheel choice, seatpost stiffness, and more, all in a controlled environment across different simulated road surfaces. Make every watt count and unlock your bike’s full performance potential.

The Technical Bit
How does the Pedalling Efficiency Rig Work?
The Pedalling Efficiency Rig (PER) will act as a bicycle dynamometer to measure rider input power and compare this with output power at the roller surface in a controlled environment, to determine the mechanical losses of a bicycle and thus its efficiency, more accurately than other methods currently in use.
Rolling resistance, component stiffness and chain friction can be measured in isolation with our smaller mechanical test rigs, however the PER has been designed to measure efficiency of the dynamic system as a whole and how all components interact with each other to transmit rider power into forward motion.
Rider input power will be measured at the pedals via a bespoke system to isolate LH and RH inputs and provide radial and tangential forces, enabling force vectors through crank rotation to be plotted.
The bicycle will initially be mounted via the front forks using bespoke mounting fixtures, enabling the bike to pivot and roll. The rear wheel will be in contact with a 2m diameter roller with interchangeable surfaces.
Whilst riding on the PER, the bike will generate its own resistance and losses through the tyres, drivetrain, bearings, however there will be no aerodynamic drag for the bike and rider to overcome. To compensate for this, aerodynamic resistance is applied to the roller via electromagnetic resistance brakes, based upon wheel speed and a drag-velocity profile of a rider of a given CdA, taken from Wind Tunnel data.
