Ride farther, faster, smarter.
Cycling Tools & Calculators
Free tools for every cyclist — power-to-weight calculator, bike gear ratio calculator, cycling calorie calculator, bike speed calculator, bike frame size calculator, and bike chain length calculator.
Cycling Power-to-Weight Calculator
Turn your FTP and body weight into watts per kilogram, see where you land from recreational to pro, and add a bike weight for the system W/kg that decides who wins the climb
Bike Gear Ratio Calculator
Enter your chainring and cog teeth and wheel size to get the gear ratio, gear inches, development per pedal stroke, and the speed you'd ride at any cadence — compare gears across any setup
Cycling Calorie Calculator
Estimate the calories you burn from your weight, ride time and intensity using the MET formula — with a leisure-to-racing scale and the burn rate per hour to help you fuel and recover
Bike Speed Calculator
Work out your speed two ways — from cadence, gearing and wheel size, or straight from distance and time — with the answer in both km/h and mph for road, gravel and mountain bikes
Bike Frame Size Calculator
Find your recommended frame size from your height and inseam for road, mountain and hybrid bikes — a size range with S/M/L labels plus the full height-to-size chart for each type
Bike Chain Length Calculator
Get the correct chain length from your chainstay, largest chainring and largest cog using the standard formula — the length in inches and the exact number of links to run
Museum of Cycling & the Bicycle
Wander an immersive museum of the bicycle and the sport it built — the evolution of the machine from the dandy horse and penny-farthing to the modern road, mountain, and electric bike, the anatomy of a bike part by part, the great races from the Tour de France to Paris–Roubaix, and the culture and gear of cycling, each in its own gallery, so you can get to know the stories behind every machine and race: how each one came to be, what makes it matter, and the role it plays in the world of cycling.
