How Much Torque Do I Need on My Electric Bike?

One of the most important details to consider in an electric bike is the amount of torque that it generates. Torque has a direct impact on how well your electric bike can start from zero and climb steep inclines. Also, a higher torque means less pedaling effort, saving you energy.

In this article, you will learn all there is to know about ebike motor torque. And we’ll discuss how much torque you need on an electric bike.

What is Torque?

Torque is the measurement of force that causes an object to rotate on its axis. On an electric bike, torque determines how quickly the back wheel rotates. Thus, the more torque you have, the faster the wheel will rotate, and the more you will accelerate.

Torque is measured in Nm, which is short for Newton meters. The average Nm on an electric bike can range from 50 to 80 Nm. More powerful electric bikes can have up to 120 Nm.

How Does Torque Affect My Bike?

Torque has a direct impact on the overall performance of your electric bike. The most important detail to remember is that it influences your rate of acceleration. Put simply, a higher torque will enable you to start from zero and climb steep inclines more easily.

There is another benefit to having plenty of torque. If you are carrying a heavy load, increased torque will help you get moving faster. You are also less likely to stall and come to a halt when climbing slopes. Electric bikes with lower torque require you to put in more pedaling effort.

What’s the Difference Between Torque and Wattage?

The difference between torque and speed on an ebike is an important concept to understand. Sometimes, the terms torque and wattage are used interchangeably, which is a false representation of what they mean.

As we covered earlier, torque refers to the force that causes an object to rotate. On an electric bike, torque influences the rotational power of the motor; specifically, its ability to rotate the back wheel.

Wattage, on the other hand, measures the power of the electric motor. It determines the amount of energy that the motor must produce to operate. It also influences the electric bike’s top speed.

There are two types of wattage ratings for electric bikes. The first is continuous output, which is the motor’s maximum output over an extended period. The second is peak output, the motor’s maximum output over a short period. Peak ratings are always higher than continuous ratings, as the performance spike occurs in short bursts.

How Much Torque Do I Need on My Ebike?

That depends on what you intend to use your electric bike for.

Do you ride in an area with many steep hills and unpredictable terrain? An electric bike with a high torque rating can help you overcome those obstacles. Do you ride in an area with mostly smooth, flat terrain? You may only need an electric bike with moderate torque to get around.

Here is a reference table to help match your torque rating with your needs.

Is a Torque Sensor Worth It?

All electric bikes have sensors that tell the engine when to run, when to stop, and how much power to supply.

The two main types of ebike sensors are cadence and torque. Cadence sensors measure when you pedal to supply the right amount of pedal assist. Torque sensors measure how hard you pedal, resulting in a smoother, more responsive pedal assist.

Cadence sensors are best suited for casual riders on a budget. Torque sensors are best suited for riders who often navigate hilly areas and unpredictable terrain. With a torque sensor, the ability to measure how hard you pedal results in a more precise, intuitive power delivery.

The Right Torque for the Right Ride

Ebike motor torque is an important factor to consider when choosing an electric bike.

Torque has a huge impact on acceleration. It determines your ability to start at a complete stop, climb steep inclines, and pedaling effort. Choosing an electric bike with the proper torque rating will help you have a more personalized and enjoyable riding experience.

FAQ

Do I Need a Torque Arm on My Ebike?

A torque arm is a special piece of metal that supports the axle on an electric bike motor. They help support the part of the bike frame where the axle connects to the front or rear wheel.

Whether you need a torque arm on your electric bike depends on your power output and motor placement.

They are typically recommended for front- or back-motor electric bikes with a 750w power output. They are also recommended for front-motor electric bikes with a 500w power output. You should also install a torque arm when you convert a standard pedal bicycle into an electric bike.

Manufacturer electric bikes with a 250w power output usually do not need a torque arm. But you can still install one if you wish.
