Bike Gear Ratio Analyzer
Sports
Free · Designed for iPad. Not verified for macOS.
Take the guesswork out of gearing.
Whether you’re planning a race, building a new bike, swapping chainrings, or just curious about your drivetrain’s limits, Bike Gear Ratio Analyzer gives you real-world insight — instantly.
Enter your chainrings, cassette, wheel size, power, and preferred cadence, and the app calculates:
• Gear ratios
• Speed at any cadence
• Climbing limits based on gradient & power
• Whether a specific hill is rideable at your minimum cadence
Perfect for road cyclists, gravel riders, mountain bikers, triathletes, and mechanics looking to select the right drivetrain before hitting the road or trail.
Plan smarter. Climb confidently. Ride faster.
Updated with new features including a chain length estimator and a CdA analyzer.
