About Bike Speed

Bike speed is determined by multiple factors including cadence, gear ratio, power output, and external conditions. Understanding these relationships helps optimize your cycling performance.

Speed Factors:

Cadence: Pedaling rate in revolutions per minute
Gear Ratio: Relationship between chainring and cassette
Power Output: Energy transferred to the pedals
External Conditions: Wind, road surface, elevation

Speed Optimization:

Maintain optimal cadence (80-100 RPM)
Choose appropriate gear ratios for terrain
Improve power output through training
Minimize aerodynamic drag
Consider external conditions
