How to Use the BMX Gear Calculator

Step 1: Select your wheel size from the dropdown menu. BMX bikes typically come in 20″ or 24″ wheel sizes.

Step 2: Choose the tire width that matches your bike’s setup. Options include 1.75″, 1.95″, and 2.1″.

Step 3: Enter the number of teeth on your chainring. This is usually between 20 and 60 teeth, with 44 being a common choice for many riders.

Step 4: Input the number of teeth on your rear cog. This typically ranges from 9 to 22 teeth, with 16 being a popular option.

Step 5: Click the “Calculate” button to generate your gear calculations.

Step 6: Review the results displayed on the screen. You’ll see the calculated gear inches, gear ratio, and rollout in inches.

Step 7: Interpret the results. A higher gear inch value indicates a “taller” gear, which is better for higher speeds but requires more effort to pedal. A lower value represents an “easier” gear, which is better for acceleration and climbing but limits top speed.

Step 8: Experiment with different combinations of chainring and cog teeth to find the ideal setup for your riding style and preferences.

Step 9: Use the gear table to compare different gear combinations and their corresponding values.

Step 10: Consider factors such as your riding discipline (racing, freestyle, or street), local terrain, and personal strength when choosing your final gear setup.

By following these steps, you can effectively use the BMX Gear Calculator to optimize your bike’s performance and find the perfect gear ratio for your needs.
