Gearbox Speed Calculator, Used by 30,000+ cyclists.

Gearbox Speed Calculator, Plus our calculator and the full ratio chart for road, gravel, and MTB drivetrains. It is separate from the calculator so longer reference guides can grow without cluttering the main tool page. An RPM calculator is a tool used to determine the Revolutions Per Minute (RPM) of a rotating object, such as a motor, engine, or gear system. Used by 30,000+ cyclists. Gear Ratio Calculator Designing a gear train? The built-in gear ratio calculator works out the ratio between meshing gears automatically. Add a driving gear and a driven gear, and the gear generator shows the resulting speed ratio and direction of rotation - handy for gearbox design, speed reduction, and torque multiplication. The gear ratio speed calculator will determine the speed ratio of your two-gear system, while explaining the concepts of gear ratios along the way. The gear ratio is typically represented as a numerical value, such as 3:1 or 4:1. Easily calculate gear ratios and speeds per gear with our Gearbox Calculator for cars, motorcycles, or custom projects. Calculate vehicle speed (MPH & km/h) based on engine RPM, transmission gear ratio, final drive, and tire diameter. Free online Gearbox Calculator – instantly find output speed (RPM) and speed reduction using input RPM and gear ratio. Jake Odell, thanks!) Tom Kunicki has a calculator with specific features useful for fixed-gear and singlespeed riders: "Rabbit, A May 26, 2026 · The gear ratio and speed calculator plays a crucial role in determining the optimal gear ratio for different riding conditions, such as long-distance and short-distance riding. Additionally, some calculators may ask for Motorcycle speed and sprocket calculator with bike database for gearing, sprockets, tires and chains of over 1900 bikes. Calculate GEAR, RPM, MPH, TIRE DIAMETER This calculator is for entertainment value only. Engine RPM and gear ratio calculators use mathematical formulas to calculate the optimal gear ratio for a given engine RPM. Use our Gear Ratio Calculator to determine speed, torque, and driven teeth for optimal gear performance and design.
