1. What is the RAD Bike Calculator?

The RAD (Rider Area Distance) calculator helps determine the optimal bike fit by calculating the recommended distance between the rider and the bike's handlebars based on the rider's height.

2. How Does the Calculator Work?

The calculator uses the RAD equation:

Where:

• \( Height \) — Rider's height in centimeters
• \( 0.426 \) — Standard coefficient for bike fitting

Explanation: The equation provides a proportional distance that helps achieve a comfortable and efficient riding position.

3. Importance of RAD Calculation

Details: Proper bike fit is crucial for comfort, efficiency, and injury prevention. The RAD measurement helps position the rider optimally relative to the handlebars.

4. Using the Calculator

Tips: Enter your height in centimeters. The value must be valid (height > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is 0.426 used as the coefficient?
A: This coefficient represents the optimal proportional distance based on anthropometric studies of bike fitting.

Q2: Should I adjust my bike based solely on RAD?
A: RAD is a starting point. Individual adjustments may be needed based on flexibility, riding style, and comfort.

Q3: Does this work for all bike types?
A: The calculation is most applicable to road bikes. Mountain bikes and other styles may require different fitting approaches.

Q4: How precise should I be with this measurement?
A: Within 1-2 cm is generally acceptable, as comfort and flexibility also play important roles.

Q5: Should I measure height with or without shoes?
A: Measure without shoes for the most accurate height measurement.
