Gear Ratio Formula:
From: | To: |
The gear ratio is the ratio of the number of teeth on the chainring to the number of teeth on the cog. It determines how many times the rear wheel turns for each pedal revolution.
The calculator uses the gear ratio formula:
Where:
Explanation: A higher gear ratio means more speed but requires more effort, while a lower ratio provides easier pedaling but less speed.
Details: Choosing the right gear ratio is crucial for optimal performance, whether for speed, climbing, or general riding comfort.
Tips: Enter the number of teeth on your chainring and cog. Both values must be positive integers (typically between 20-60 for chainrings and 10-30 for cogs).
Q1: What's a typical gear ratio for mini bikes?
A: Common ratios range from 2.5 to 6.0, depending on the bike's purpose and rider's strength.
Q2: How does gear ratio affect speed?
A: Higher ratios allow higher speeds for the same pedaling rate, but require more effort to pedal.
Q3: What's better for climbing hills?
A: Lower gear ratios (smaller chainring or larger cog) make hill climbing easier.
Q4: Can I change my gear ratio?
A: Yes, by changing either the chainring or cog to one with a different number of teeth.
Q5: What's the difference between gear ratio and gear inches?
A: Gear inches incorporates wheel size, while gear ratio is purely based on teeth count.
