The electric motor plays an important role in deciding which vehicle to buy or which not, because the efficiency and performance of it will greatly affect the working of vehicles.

There are different types of electric motors being used in e-bikes, but the hub motor is the top choice among most of the producers. E-bike manufacturers choose to use this motor in pedal-assisted electric bicycles in order to reduce production costs and provide the ultimate riding experience to the riders. There must be some reasons, apart from being cost-efficient, that the top companies are using this specific type in their vehicles.

Let's explore those reasons to help you understand why hub engine is best for you to buy.

What is the Hub Motor and its Role in Running the Bike?

The Ebike hub motor is a mechanical component of a vehicle that makes the wheel rotate to reach from point A to point B. It applies the electric energy produced with the help of a battery installed in it to run the bike.

Hub motors are usually installed in the rear wheel to apply torque to move the wheel. It operates separately from the drive terrain belt and is not being shifted by the transmission system attached to the vehicle.

Electric bikes can not run without an electric motor like the hub, mid-drive, friction drive, brushed or brushless because these types work as the engine of the vehicle, and without an engine, there will be no movement.

How Does Ebike Hub Motor Works?

Electric bike hub motor works in the same manner just like other electric motors work in different vehicles. When you press the turn-on button of your cycle, the copper windings layers twined around the spokes attract the current from the battery to the cords through the electric motor converter, which converts the stator into an electromagnet.

It consists of a ring of permanent magnets that generate torque when the stator's electromagnets cause the blades to rotate, resulting in higher torque. Before choosing an electric bike for commuting, you should learn the difference between power and torque.

Benefits of Having Hub Drive Motor in Bike

Apart from being cost-efficient, there are numerous benefits of riding an e-bike with a hub drive motor. Let's explore the other ones to help you get to know the perks of riding a pocket-friendly ride.

1. Lightweight to Ride

These electric motors are usually lighter in weight, resulting in a comfortable riding experience. You can even pedal these bikes with ease as these bikes are not bulkier in weight, keeping the bike lightweight.

On the other hand, bikes equipped with other types of motors are harder to pull while riding without electric power coming from the battery and motor.

2. Optimum Riding Speed

Electric bicycle hub motors provide optimum riding speed to the riders as they spin the rotor at a higher rate, resulting in lower RPM at which the wheels may be rotated. It is best for routine commuting and adventure rides as it provides enough torque for smooth climbing.

3. Power Efficient

Electric bikes powered with hub-drive motors provide maximum battery range as they minimise the power needs while riding. These motors are power-efficient as they provide more riding speed and road grip on steep slopes.

4. Long Lasting

These motors are more durable and long-lasting in performance because the tiny gears attached to them will be worn out after a certain amount of time. Until then, you can enjoy the power rides, and in case of motor failure, you can use the pedals to move your vehicle as well.

Key Factors to Consider While Choosing an Electric Motor for a Bike

You need to keep in mind the following factors while choosing an e-bike with an electric motor for daily or occasional commuting to make the right decision so that you can invest your resources in a worthwhile product.

  • Level of assistance required while riding.
  • Terrain, either flat or hilly, to ride on.
  • Cargo capacity for carrying groceries and other goods.
  • Your budget for buying.
  • Maximum performance and efficiency.

Different Types of Electric Motors

There are mainly three types of electric motors commonly used in electric bikes. Selecting the right one depends upon your riding style and the design of the vehicle. For example, for step-thru bikes, brushless hub motors are a perfect combination.

1. Hub Motors

As the name suggests, these motors are usually integrated into the vehicle's rear or front wheel. According to some estimations, 50-70% of e-bikes are equipped globally with these motors due to only two reasons: power and cost efficiency.

These motors come in geared or gearless variations with an easy-to-attach design, eliminating the need for drive terrain modifications.

2. Mid-Drive Motors

After electric bike hub motors, the mid-drive motors are the most widely used moving component in bicycles. It covers almost 30% of the e-bike market around the globe.

These motors are being attached to the bottom bracket area of the vehicle and directly drive the crankset, providing power through the rear gear set and transmission system.

3. Brushed or Brushless Motors

Both electric motors are widely used by smart manufacturers like Engwe in their bikes like Engwe LE20 to provide optimum riding experience. Bushed motors have stationary magnets in the stator circled around the rotating armature that consists of wire windings that interact with a fixed magnetic field. On the other hand, brushless motors contain fixed magnets in the rotor, which revolves around a stationary armature.

4. Friction Drive Motors

Friction drive motors are emerging as a niche product, especially for lightweight electric bikes. These motors use friction produced between the rubberised wheel pressed against the tyre to propel the bike forward.

It has been observed that their performance is not up to the mark for a wider audience, making it a less adaptable choice for riders.
