Electric Bike Motors: Power and Torque - Understanding Performance Metrics

When it comes to electric bike motors, understanding the difference between power and torque is essential to understanding performance metrics. Put simply, power is the rate at which work is done, while torque is the momentary force that rotates the motor. In other words, power is how fast the motor can spin, while torque is how much force it can exert.

To put it another way, power is related to the speed of the bike, while torque is related to the acceleration. A motor with more power will be able to spin the wheels faster, while a motor with more torque will be able to accelerate the bike more quickly.

There are a few different ways to measure power and torque. The most common unit of measurement is the watt, which is a measure of power. One watt is equal to one joule of energy per second. To put that in perspective, a human can sustain about 100 watts of power for an extended period of time, while a car engine produces thousands of watts of power.

Torque is usually measured in Newton-meters (Nm). One Newton-meter is the amount of torque required to accelerate an object with a mass of one kilogram at a rate of one meter per second squared. For electric bike motors, torque is often quoted in “peak” values, which is the maximum amount of torque that the motor can produce.

When it comes to electric bike motors, power and torque are both important. A motor with more power will be able to spin the wheels faster, while a motor with more torque will be able to accelerate the bike more quickly. Understanding the difference between these two metrics is essential to understanding electric bike performance
