1. What is RPM on an Exercise Bike?

Definition: RPM (Revolutions Per Minute) measures how many full rotations the bike's pedals make in one minute.

Purpose: Monitoring RPM helps cyclists maintain optimal cadence for efficient workouts and performance tracking.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( RPM \) — Revolutions per minute
• \( S \) — Speed in miles per hour (mph)
• \( TD \) — Tire diameter in inches
• \( 1056 \) — Conversion factor (feet to inches and hours to minutes)

Explanation: The formula converts speed and wheel size into pedal rotations per minute.

3. Importance of RPM Calculation

Details: Proper RPM tracking helps cyclists maintain efficient pedaling cadence, typically between 60-100 RPM for optimal performance and reduced injury risk.

4. Using the Calculator

Tips: Enter your cycling speed in mph and your bike's tire diameter in inches. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a good RPM range for cycling?
A: Most cyclists maintain 60-100 RPM, with 80-90 RPM being ideal for endurance riding.

Q2: How do I measure my bike's tire diameter?
A: Measure from ground to wheel axle (radius) and multiply by 2, or check the tire sidewall markings.

Q3: Why does tire diameter affect RPM?
A: Larger wheels cover more distance per rotation, requiring fewer RPMs at the same speed.

Q4: Can I use this for outdoor bikes?
A: Yes, this calculation works for any bicycle when you know speed and tire diameter.

Q5: What if my bike has a flywheel instead of tires?
A: Use the flywheel diameter measurement instead of tire diameter in the calculation.
