1. What is Bike Gear Speed?

Bike gear speed refers to the speed at which a bicycle travels based on the gear ratio and pedaling cadence. It helps cyclists understand how different gear combinations affect their speed.

2. How Does the Calculator Work?

The calculator uses the bike gear speed equation:

Where:

• \( gear\_inches \) — The gear inches of your bike setup
• \( cadence \) — Your pedaling rate in revolutions per minute (RPM)
• 336 — Conversion factor to get speed in miles per hour (mph)

Explanation: The equation calculates how far the bike travels with each pedal revolution and converts this to miles per hour based on your cadence.

3. Importance of Gear Speed Calculation

Details: Understanding gear speed helps cyclists choose appropriate gears for different terrains and maintain optimal cadence for efficiency and endurance.

4. Using the Calculator

Tips: Enter gear inches (a measure of your bike's gear ratio) and your pedaling cadence in RPM. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are gear inches?
A: Gear inches is a measure that combines wheel size and gear ratio to show how far the bike moves with each pedal revolution.

Q2: What is a typical cadence?
A: Most cyclists maintain 60-100 RPM, with 80-90 RPM being common for road cycling.

Q3: How can I measure my cadence?
A: Use a bike computer with cadence sensor or count pedal revolutions for 15 seconds and multiply by 4.

Q4: Why does speed vary with gear inches?
A: Higher gear inches mean more distance per pedal revolution, resulting in higher speed at the same cadence.

Q5: How accurate is this calculation?
A: It provides theoretical speed on flat ground without considering factors like wind resistance or tire pressure.
