All You Need to Know about Ebike Motor- HAOQI Ebike

When choosing a reliable e-bike, it's critical to consider the motor's quality. Some are more reliable than others, while others need more maintenance. It’s one of the essential components of an e-bike in charge of powering various parts of the bike, which allows you to accelerate and climb hills while riding your e-bike.

Haoqi has efficient and durable bike motors that would enhance your riding performance. Whether you are new to e-bikes or an expert seeking to know more about e-bikes, this article will help you learn everything you need to know about e-bike motors and how it works.

Definition of the Electric Bike Motors and its Function

An electric bike motor is a device that assists in operating an electric bicycle. It’s typically mounted on the bike's frame and supplies power to the drivetrain, which propels the bike forward. Electric bike motors come in various sizes and styles, but they all serve the same primary function – to assist you in riding your bike while pedaling.

An ebike motor generates energy by converting electrical energy to mechanical energy. This energy turns the bike's gears, propelling the wheels forward. Most electric bike motors are brushless, meaning they lack brushes that can wear out over time. They are also more efficient than brushed motors, which means they provide more power for the same amount of electricity.

Types of Electric Bike Motor

When shopping for the right electric bike, you may be overwhelmed by the various options available. You should choose a reliable ebike motor based on your expected usage and preferences.

There are two main types of motors: hub and mid-drive motors.

1. Hub Motors

Hub motors are the most common type of e-bike motor and are usually direct-drive or geared. The direct-drive hub motors are the most basic type because they have internal gearing. The gears in geared hub motors help to increase the motor's efficiency.

Furthermore, hub motors are available in brushed and brushless configurations. Brushed hub motors are less expensive than brushless ones but require more maintenance. Overall, e-bikes with hub motors are less costly than their mid-drive counterparts since they are inexpensive to manufacture. But, the torque of hub motors is lesser than mid drives and other motors.

Hub motors are available in both geared and gearless configurations. Let's start with the geared hub motor.

Gear Hub Motors

A set of gears outside the small motor is an essential feature of this motor type. The part is enclosed in a casing while the gears are exposed. Compared to climbing motors, this motor type is smaller than other hub versions.

Power is generated within the casing by the motor and transferred to the wheels via the gear system. This type of motor is typically less potent than other types. However, the mechanism improves the efficiency of this part.

The geared system also addresses common torque issues and encourages the underpowered motor to produce more power. Another application for this type is that it has a more extended range, as seen in the Haoqi Rhino Electric Motorbike.

  • Long range:The geared hub motor allows you to go a longer distance on a full charge.
  • High power output:The gear hub motors' power output is incredibly higher than the gearless motors.
  • Easy maintenance:Its system doesn't frequently encounter technical issues, which makes it easy to maintain.  
  • Short life span:The geared hub motors are, unfortunately, not too durable. They have a shorter lifespan than the other types.

Gearless Hub Motors

The gearless or speed motor is a motor found in electric bikes. They are also known as direct-drive parts because they use electromagnets to propel the e-bike forward. The axle is the component a motor causes to rotate to turn the wheel. The electromagnets move the axle, allowing the e-bike to run smoothly.

The rotor and stator are the only two essential parts of the motor, automatically spinning on one side of the component. Gearless vehicles provide regenerative braking.

  • Higher top speeds:You can travel faster with this motor.
  • Improved hill-climbing angle:It is much easier to climb a hill with gearless hub motors.
  • User-friendly system:The hub drive system is simple and does not require much expertise.
  • Efficient braking features:The presence of brakes on an e-bike makes riding much more effortless.
  • Low Overall effectiveness:You might need to get the desired functionality from gearless motors. Because this is larger, the e-bike is heavier. The motor’s weight tells on that of the bike.
  • Absence of gear:You may not be able to climb steep hills or accelerate maximally due to absent gears.

2. Mid-Drive Motors

Mid-drive motors are becoming more common in e-bikes. These motors are similar to hub motors, mounted in the center of the bike's frame rather than in the wheel hubs. Because of its positioning, mid-drive can use the bike's existing gears, resulting in better hill-climbing ability and a more natural riding feel. Brushed and brushless mid-drive motors are both available.

This motor generates power and transfers it to the wheels. Chains and gears facilitate transportation. Typically, this component drives the bike's crank rather than the tires, improving the vehicle's performance.

  • Provides more power:The mid-drive motors have a higher power output.
  • Simplifies troubleshooting:You can quickly figure out what is wrong with a mid-drive motor.
  • Enhances the handling of the e-bike:Your e-bike is easier to handle with the mid-drive motors.
  • Friction results in energy loss: Friction between moving parts generate heat leading to some energy losses.
  • Repairing is difficult:Repairing a mid-drive motor might mean consulting a professional, as they are complex to repair.

How do E-Bike Motors Work?

The motor of an electric bike operates by utilizing information provided by a component known as the controller. For efficient operation, this component is present in all e-bikes. When you press the throttle or begin pedaling, the controller tells the bike's motor to turn on. The part will then use energy from the battery to generate power and cause the wheels to move.

The battery is the heart of an electric bike motor. It powers the ebike, which rotates the pedals for you. Electric bikes are an excellent choice for people who want to ride but lack the strength or endurance to pedal up hills or over long distances.

The rider must provide input to these electric bikes. When you press the throttle, the controller sends a signal to the motor, which causes it to move. The more quickly you pedal, the more power it receives.

So, how does this motor work with the rest of the bike?

The motor is the most critical component of an e-bike, as it provides the power to move the bike. An e-bike would be a regular bicycle without a motor. Typically, it's located in the hub of the back wheel and can be geared or directly driven. The rest of the e-bike's operation with the motor is pretty simple. The battery powers the controller and modulates the current flow from the battery. Then, the rest of the bike is powered by the motor.


Undeniably, a good bike must possess an excellent motor for effectiveness, and that is precisely what Haoqi e-bikes offer. The quality of your e-motor bike is critical. It's your bike's engine, and you want to ensure it's up to the task flow. Cheap e-bikes might have poor motor quality. Invest in a high-quality motor that will last longer, provide more power, and be more dependable.
