Estimate Your Cycling Ride Time with Precision

veloETA.com is the most advanced cycling calculator and bicycle ride estimator available online. Upload your GPX route file and get accurate ride time estimates based on real physics — gravity, aerodynamic drag, and rolling resistance.

Tire Pressure Calculator & Optimizer

Our tire pressure calculator helps you find the optimal PSI for any surface. Whether you ride road, gravel, or MTB — veloETA analyzes your route segment by segment and recommends the best tire pressure optimization for minimal rolling resistance and maximum comfort.

How It Works

1. Upload a GPX file — from Strava, Komoot, Garmin, or any cycling app
2. Define surface segments — mark road, gravel, cobblestone, dirt, and more on the interactive map
3. Enter rider data — weight, power output, and aerodynamic position
4. Get results — estimated ride time, optimal tire pressure, and segment-by-segment analysis
