About a year ago I designed a mathematical model for cycling that relates velocity and power dynamically, considering multiple parameters that determine the forces involved such as the weight of the rider and the bicycle, the grade of the road, the rolling resistance of the tyres or air density based on altitude and temperature.
Sure, there are multiple online calculators which estimate speed from power and viceversa, but these are based on terminal velocity and cannot be used for estimating one from the other dynamically.
Designed just for fun, soon I started to realise its multiple applications. Among them:
- Detecting failures in power-meter units during climbs
- Accurately predict duration of routs, based on the physiology of the cyclist (see Critical Power and W’)
- Use it as an Opposing Force Power Meter
- Estimate CdA (Drag coefficient * frontal Area) without the need of a velodrome, or having to maintain the same power
And a bonus (corollary of 2.): Can I beat that Strava segment? Check it from your sofa. You’re welcome!
I presented this idea named Bicinetica (bicycle and kinetics in Spanish) as a project for the XXI Spin-Off of the University of Málaga. The project was selected by Sprita Startups, a local company part of TOPdigital group, which will provide advise and seek funding opportunities.
