Cycling Calculators
Practical bike tools for road, gravel, mountain, commuting, and indoor riding. The category now covers Batch 1 mechanics tools, Batch 2 training metrics, and Batch 3 fit and equipment calculators for frame size, saddle height, tire pressure, climb-focused weight savings, and e-bike range planning, plus Batch 4 planning tools for ride fuelling, sweat-rate hydration, race pacing, commute savings, and drivetrain replacement planning.

Estimate cycling FTP from a 20-minute, 8-minute, or ramp test and get watts per kilogram plus a full Coggan power-zone table.
Cycling Power Zone Calculator
Calculate all 7 Coggan cycling power training zones from FTP. Get watt ranges, W/kg fitness category, heart rate estimates, and workout examples for each zone.
Calories Burned Cycling Calculator
Calculate cycling calories burned using weight, duration, and ride intensity for indoor and outdoor workouts.
About the Cycling Category
Batches 1 through 4
The category now covers three distinct parts of cycling decision-making. Batch 1 focuses on speed, gearing, wheel rollout, and climbing mechanics. Batch 2 expands into training metrics with heart-rate zones, Training Stress Score, CTL and ATL load tracking, VO2 max estimation, and watts-per-kilogram category benchmarking. Batch 3 adds bike-fit and equipment tools for frame size, saddle height, tire pressure, climb-focused weight savings, and e-bike range. Batch 4 adds ride fuelling, sweat-rate hydration, race finish-time estimation, commute savings, and drivetrain wear planning.
Who These Tools Are For
The category is aimed at cyclists who want more than generic fitness calculators. Road riders, gravel riders, mountain bikers, commuters, e-bike users, indoor trainers, and club-level racers all make decisions about cadence, gearing, power, and pacing that benefit from transparent calculations instead of guesswork.
What Makes This Category Useful
- Clear cycling-specific terminology instead of generic workout language
- Physics and drivetrain math that can be audited and compared
- Training metrics, fit tools, and planning tools that work alongside the existing FTP and power-zone calculators
- Practical planning for gear choice, race pacing, commute value, equipment setup, and performance benchmarking
