Electric Skateboard Gear Ratio Calculator

This tool evaluates your gear ratio based on pulley sizes and wheel diameter, then provides clear, actionable feedback. It tells you whether your setup is speed-biased, balanced, or torque-biased, and whether a larger wheel pulley is recommended.

📌 How to Use This Result

• Speed-biased: Lower torque, lighter load, best for small wheels and flat terrain.
• Balanced: Recommended setup for most riders and conditions.
• Torque-biased: Strong acceleration and hill climbing, ideal for larger wheels.
• Under-geared: Indicates that a larger wheel pulley is strongly recommended.

This tool evaluates mechanical gearing only. Actual top speed is primarily limited by ESC configuration and battery voltage, not by gear ratio alone.

🔧 Recommended Wheel Pulleys

Based on your wheel size and gear ratio result, selecting the correct wheel pulley is critical for torque, motor load, and ride comfort.
