This Top Speed and Gear Ratio Calculator is an essential tool for electric bike enthusiasts and DIY e-bike builders. It enables you to calculate your bike's gear ratio and estimate its maximum speed based on motor RPM, sprocket teeth count, and wheel diameter. This powerful electric bike top speed calculator and gear ratio calculator tool helps optimize performance and component selection for a smoother ride.
Follow these simple steps to get accurate calculations:
After filling in all the required fields, click the Calculate button. The calculator will display the gear ratio and the estimated top speed (in mph). This tool is perfect for fine-tuning your e-bike setup and ensuring your ride meets performance expectations.
The gear ratio is the proportion between the wheel sprocket and the motor sprocket teeth count. A lower gear ratio can yield a higher top speed, while a higher gear ratio provides more torque. Understanding this ratio is crucial for balancing speed and power in your electric bike.
The estimated top speed is calculated under ideal conditions using the formula: (Motor RPM / Gear Ratio) * Wheel Diameter * 0.002975. In real-world scenarios, factors like wind resistance, terrain, and battery performance can affect the actual speed.
Yes, this calculator is designed to work with a wide range of electric bikes. However, for the most accurate results, always refer to your bike’s specific manufacturer specifications.
Whether you are looking to perform a motor RPM conversion or determine the ideal bike gear ratio, this calculator is your go-to resource for maximizing performance and achieving the perfect balance between speed and torque.
