Top 3 Most Common E Bike Motors and Which Is Right for You.

Not all motors are created equal. In fact, there are a few different types of eBike motors out there, each with their own unique set of pros and cons.

Ah, electric bikes. The ultimate way to pedal your way to glory without breaking a sweat. And what’s the heart of an eBike, you ask? Why, the motor, of course! But not all motors are created equal. In fact, there are a few different types of eBike motors out there, each with their own unique set of pros and cons. So, without further ado, let’s take a tour of the different eBike motors and see which one is right for you.

Ebike Hub Motor

First up, we have the hub motor.

As the name suggests, this type of motor is located in the hub of the wheel, which means it’s hidden away from view. The hub motor is known for its smooth and quiet operation, making it a popular choice for city riders who want to blend in with the crowd. However, it’s not the most powerful motor out there, so it may not be the best choice for off-road adventures or steep hills.

A bit more on hub motors and the pros and cons

A hub motor is a type of electric bike motor that is located in the hub of the wheel, either the back or front wheel. The hub is the centre part of the wheel where the spokes attach, and the motor is encased within the hub, making it a relatively hidden component of the bike.

Pros of a hub motor include:

  • Smooth and quiet operation: Because the motor is located in the hub of the wheel, it doesn’t produce as much noise as other types of motors, making it a great choice for city riders who want to blend in with the crowd.
  • Easy installation: Hub motors are relatively easy to install, which makes them a great choice for those who want to convert their existing bike into an electric bike.
  • Cost Effective: Hub motors are the most common type of motor as they are relatively affordable and most modern hub motor bikes pack a load of punch at a really competitive price point.

Cons of a hub motor include:

  • Reduced power: Because the motor is located in the hub of the wheel, it potentially cannot produce as much power as mid-drive motors, which means it may not be the best choice for off-road adventures or steep hills.
  • Reduced efficiency: The hub motor is less efficient than other mid-drive motors, so it may not be the best choice for long-distance riding.
  • Potentially reduced torque: Some of the cheaper and nastier hub motors have less torque than other types of motors so it may not be the best choice for climbing hills.
  • Requires a good controller: A good hub motor paired with a sub-par controller will perform terribly, there are millions of hub/controller combinations, so having someone knowledgable or testing a config is a must.

Overall, hub motors are a great choice for city riders who want a smooth and quiet ride, but they may not be the best choice for off-road adventures or steep hills. They are also less efficient and less powerful than other types of motors.

Mid Drive Ebike Motor

Next, we have the mid-drive motor.

This type of motor is located in the middle of the bike, between the pedals and the rear wheel. Mid-drive motors are known for their high efficiency and power, making them a great choice for off-road adventures or steep hills. However, they can be a bit more expensive and complex to install, so they may not be the best choice for the budget-conscious rider.

A bit more on mid-drive motors and the pros and cons

Mid-drive motors, also known as crankset motors, are a type of electric bike motor that is located in the middle of the bike, between the pedals and the rear wheel. They are connected to the bike’s chain and gears, which allows them to take advantage of the bike’s transmission system, making them highly efficient.

Pros of mid-drive motors include:

  • High efficiency: Because they are connected to the bike’s transmission system, they can take advantage of the bike’s gears, which makes them highly efficient and can result in a longer range on a single charge.
  • High power: Mid-drive motors can produce a lot of power which makes them a great choice for off-road adventures or steep hills.
  • Better weight distribution: Because the motor is located in the middle of the bike, the weight is distributed more evenly, which makes the bike easier to handle and more stable.

Cons of mid-drive motors include:

  • Expensive and complex installation: Mid-drive motors can be more expensive and complex to install than other types of motors, which may not be the best choice for the budget-conscious rider.
  • Increased maintenance: Mid-drive motors require more maintenance than other types of motors because they are connected to the bike’s transmission system.

Overall, mid-drive motors are a great choice for those who want a high-performance e-bike, but they can be more expensive and complex to install than other types of motors. They offer high efficiency and power, and better weight distribution. On the more premium mid-drive motors like Bosch or Yamaha make hill climbing a breeze with enough headroom to carry cargo up hills with ease such as child seats.

Friction Drive Ebike Motor

Last but not least, we have the friction drive motor.

This type of motor is a bit of a wild card. It doesn’t have a specific location on the bike and it relies on friction to power the bike. Friction drive motors are known for their simplicity and affordability. However, they are not as powerful as other types of motors and can be affected by weather conditions.

These are the least common type of eBike motor.

A bit more on friction-drive motors and the pros and cons

A friction drive motor is a type of electric bike motor that relies on friction to power the bike. Unlike other types of motors, which are fixed to a specific location on the bike, friction drive motors can be mounted to the frame or even the rear wheel of the bike, using a roller that comes into contact with the tire to provide propulsion.

Pros of friction drive motors include:

  • Simplicity: Friction drive motors are relatively simple in design and easy to install, which makes them a great choice for those who want to convert their existing bike into an electric bike.
  • Affordability: Friction drive motors are generally less expensive than other types of motors, which makes them a great choice for budget-conscious riders.

Cons of friction drive motors include:

  • Reduced power: Friction drive motors are generally less powerful than other types of motors, which means they may not be the best choice for off-road adventures or steep hills.
  • Reduced efficiency: Friction drive motors are less efficient than other types of motors, which means they may not be the best choice for long-distance riding.
  • Weather-sensitive: Friction drive motors can be affected by weather conditions, such as rain or snow, which can make them less reliable in certain environments.
  • Reduced torque: The friction drive motor has less torque than other types of motors so it may not be the best choice for climbing hills.

Overall, friction drive motors are a great choice for budget-conscious riders who want a simple and affordable option for converting their existing bike into an electric bike. However, they are not as powerful or efficient as other types of motors, and they can be affected by weather conditions. They also have less torque than other types of motors, so they may not be the best choice for climbing hills.

Electric Bike Rider Types

Which motor is right for each type of rider

There are many different types of eBike riders, each with their own unique set of needs and preferences. Here are a few examples of different types of eBike riders and the motor that best suits them:

  1. City Commuter: City commuters typically prioritize a smooth and quiet ride, as well as ease of use and maintenance. A hub motor would be a great choice for this type of rider, as it is known for its smooth and quiet operation and is relatively easy to install.
  2. Off-Road Adventurer: Off-road adventurers typically prioritize power and performance, as well as durability and reliability. A mid-drive motor would be a great choice for this type of rider, as it is known for its high efficiency and power and can take advantage of the bike’s transmission system for better performance.
  3. Hill Climber: Hill climbers typically prioritize high torque and power, as well as stability and control. A mid-drive or crank drive motor would be a great choice for this type of rider, as they both produce high torque and power, and provide better weight distribution.
  4. Budget-conscious Rider: Budget-conscious riders typically prioritize affordability and ease of use. A hub drive motor would be a great choice for this type of rider, as it is generally less expensive than mid-drive motors and is relatively simple to install.
  5. Long-distance Rider: Long-distance riders typically prioritize efficiency and power, as well as durability and reliability. A mid-drive motor would be a great choice for this type of rider, as it is known for its high efficiency and power, and can take advantage of the bike’s transmission system for better performance over long distances.

It’s worth noting that every rider is different and their needs may vary. It’s important to carefully evaluate your own needs, preferences, and budget before choosing the motor that best suits you.

You mentioned “torque”, what is that?

Torque is a measure of the rotational force that an electric bike motor can produce. It’s what allows the motor to propel the bike forward and climb hills. In general, the more torque an eBike motor has, the more powerful it is, and the better it will perform when climbing hills or accelerating.

On an eBike, torque is generated by the motor and is transferred to the wheel through the chain or belt drive. The motor controller regulates the amount of torque that is produced by the motor, based on the rider’s input (throttle or pedal assist).

The torque is usually measured in Newton-meters (Nm) or pound-feet (lb-ft) and the higher the torque, the higher the climbing ability and acceleration capabilities of the e-bike.

There are different types of motors that produce different levels of torque, for example, hub motors tend to produce less torque than mid-drive or crank drive motors. This is why some e-bikes are better suited for climbing hills or off-road adventures than others.

Keep in mind that the torque that an e-bike motor can produce is not the only factor that determines the e-bike’s performance. Other factors such as the weight of the bike, the efficiency of the transmission system, and the size of the battery also play a role.

Overall, torque is an important factor to consider when choosing an eBike motor as it determines the power and climbing ability of the bike. The more torque the motor produces, the better it will perform when climbing hills or accelerating.

Crash course on eBike batteries, volts & amps.

The voltage and amp-hours (Ah) of an e-bike battery are two important factors that affect the performance of the e-bike.

Voltage: Voltage is a measure of the electrical potential difference in a circuit. The voltage rating of an e-bike battery determines the amount of power that the motor can receive. A higher voltage means more power, which in turn means better acceleration and hill-climbing ability. Most e-bike batteries have a voltage of 36V or 48V.

Amp-hours (Ah): Amp-hours (Ah) is a measure of the amount of energy stored in a battery. The amp-hours rating of an e-bike battery determines how long the battery will last before needing to be recharged. A higher amp-hours rating means more energy stored, which in turn means a longer range before needing to be recharged. Most e-bike batteries have an amp-hours rating of 10Ah to 17Ah.

In general, a higher voltage and amp-hours rating will provide better performance for an e-bike. A higher voltage means more power, which results in better acceleration and hill-climbing ability. And a higher amp-hours rating means a longer range before needing to be recharged. However, keep in mind that these factors are not the only ones that determine the performance of the e-bike, other factors such as the weight of the bike, the efficiency of the transmission system, and the size of the motor also play a role.

Additionally, it’s important to note that as the voltage and amp-hours of a battery increase, the weight and size of the battery also increases. So, if you’re looking for an e-bike with a smaller and lighter battery, you may have to compromise on power and range.

So, there you have it! The different types of eBike motors in a nutshell. From the stealthy hub motor to the powerful mid-drive motor, there’s an eBike motor out there for every type of rider. Just remember to think about your riding style and budget before making a decision. Happy pedalling!
