Hub Motor: Not Magic, but Like A Magic

Bikes are efficient and affordable as regular transportation. Do you ever wonder what makes your bike go? Sure, the user can push the pedals, causing the gears to turn and make the wheels move, but what about electric bikes? If you prefer not to pedal or arrive at your destination tired and sweaty, there is a simple solution. Every ebikes for sale, also known as an electric bicycle, has a motor that drives the pedal assistance. When the pedal assistance, and there with the motor, is switched on, you can easily cycle without having to deliver a lot of power yourself. The motor, like the heart of an electric bicycle, provides a steady stream of power, and it is also one of the core configurations that we should pay attention to when choosing an electric bicycle. So, how much do you know about motors?

l  As a type of motor often used in ebikes, why is the Hub motor so popular? What about its performance?

The hub motor (also called wheel motor, wheel hub drive, wheel hub motor or in-wheel motor) is an electric motor that is incorporated into the hub of a wheel and drives it directly. They are usually found on electric bicycles and motorcycles as an indispensable part, providing sufficient power for the running process.

l  How does an Electric Bike Motor work?


The modern electric bike motor has no brushes, so how does the motor spin? Magic?  It does it by the magic of interior design. The motor has three big power wires leading into it. Each wire energizes one third of the motor. The microprocessor is in the motor controller, which sends a pulse of DC current down the wires in sequence. In this way, the controller is constantly switching the magnetic polarity of the coils, and the energized coil is constantly attracted to the next magnet down the row.

The motor controller is the brains of electric bikes. The nerves are the wiring that goes to the rest of the bike. The wire to the motor is like the nerves to the legs, and the wires to the handlebars are the nerves to the senses. On the handlebars there is the throttle that controls the speed. There is a display that shows your speed and distance, the battery level, the power being used, and the speed limit level. The speed limiter lets you choose less than full power when you want maximum efficiency. The wire to the battery is like the bloodstream. It delivers power to the body.

Of course, there is more than one type of motor that powers the wheels, and they can be roughly divided into four categories: Friction drive, left side drive, mid drive, and hub motor drive. While driving various types of electric vehicles efficiently, they also have some shortcomings.

l  What’s the verdict? It depends!

Friction drive uses the motor to rub the tire, pushing the tire by friction. As you can imagine, a bit of water or mud on a tire could affect this method. Left side drive means a motor uses the left side of the rear wheel to transfer the power. It might be an additional chain and sprocket on the left, or it might be made so a rotating disc pushes on the spokes on the left side of the wheel. The main drawback of left side drive is noise. Most are very loud, with the extra chain and sprocket. Mid drive means the motor is mounted in the middle of the bike, near the pedals. Then the motor connects to the pedals, so the motor actually helps the rider pull the chain on the bike. Mid drives work great, when the rider chooses the right gear. Choosing too high a gear can result in lots of chain and gear wear, and in some cases actually harm the motor or the battery. So with a mid-drive bike, you have to think about which gear to use at all times. However, many off-roaders like the power and reliability of hub motors, and many commuters prefer lightweight, stealthy and unobtrusive mid-drive motors. It really depends on which features fit you best.

But I still have to mention that the simplest and most elegant solution is the hub motor. A hub motor is the most common motor type out there. It sits in the middle of the bike’s wheel. A perk of the hub motor is that it is very easy to deal with because they require little to no maintenance. With the hub motor, the motor is actually located right inside the hub of the wheel. This makes it easy for the novice to install on a bike, and the result is a quiet ride that is never in the wrong gear.

As an independent drive system, hub motors also add safety and convenience. Since the hub motor and the pedal drive system are completely independent, you can lose one and still get home on the other. Chain breaks while you’re hitting it hard on a trail? Toss the chain in your bag and ride home on just electric power. Does the hub motor somehow fail? Pedal back. Either way, you’ve got a backup. This can be huge if you’re far from home, reducing the chance of accidents and giving you a smooth trip.

A motor that’s right for you adds plenty of power and fun to your ride! If you are in the market for an affordable option that offers a great amount of performance in its own right, a geared hub motor is a good choice.

Ebikes produced by Magicycle are occupied with high-performance hub motors. It has no frame and no power loss, and achieves energy efficiency. Coupled with its 86NM torque, it provides more power, all for a smoother, longer-term and more hearty ride.
