1. What is Bike Cadence?

Cadence in cycling refers to the number of revolutions per minute (rpm) of the crank arms. It's an important metric for cyclists to maintain efficient pedaling and avoid fatigue.

2. How Does the Calculator Work?

The calculator uses the cadence formula:

\[ Cadence = \frac{(speed \times 60)}{(wheel\_circumference \times gear\_ratio)} \]

Where:

Explanation: The formula converts speed to distance traveled per minute, then divides by the distance the bike moves with one crank revolution.

3. Importance of Cadence Calculation

Details: Maintaining optimal cadence (typically 80-100 rpm) improves pedaling efficiency, reduces muscle fatigue, and helps prevent injuries.

4. Using the Calculator

Tips: Enter your cycling speed in km/h, measure your wheel circumference in meters, and calculate your gear ratio (chainring teeth ÷ cog teeth). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good cadence for cycling?
A: Most cyclists aim for 80-100 rpm, though this varies by rider and cycling discipline.

Q2: How do I measure wheel circumference?
A: Measure from ground contact point, roll bike one full revolution, and measure distance traveled.

Q3: What affects my cadence?
A: Gear selection, terrain, fitness level, and riding style all influence cadence.

Q4: Why is cadence important?
A: Proper cadence helps maintain efficient power output and reduces strain on muscles and joints.

Q5: Does cadence vary by bike type?
A: Yes, road cyclists typically use higher cadences than mountain bikers or commuters.
