Spinning Circles – Cycling Simulator

SimulationPhysicsApplied MathWeb Experiments

A physics-based cycling race simulator where users tune rider and environmental parameters to watch two cyclists battle in real time.

Key Features

Physics Engine

Real-time calculation of CdA, Crr, gravity, and rolling resistance.

Environment Control

Adjust wind speed, direction, and air density to see their impact.

Live Analytics

Instant visualization of speed, power, and time gaps.

About the Project

Spinning Circles is a high-performance, web-based cycling simulator that visualizes head-to-head racing dynamics. Users can adjust rider parameters (power, weight, CdA, Crr), track features (length, hills, grade), and environmental conditions (wind speed, direction, air density) while the simulation updates in real time. Live charts highlight speed, elevation, power components, and time gaps as riders race around a configurable loop.
