Buyer’s Choice

Buying a motor may sound simple and easy. But it requires a little homework so that you don’t end up having a short living product. By a little homework, we mean a proper knowledge of motors.

As mentioned above, the speed controller serves as a dynamic brake and allows you to control the speed.

Say it ‘the heart’ or ‘the brain,’ but it is an essential component of a bike.
There are millions of products in the market. Let’s see how you can decide the one for you.


Check if your motor contains hall sensors. If it is so, then the controller should be dual-mode or hall sensor mode. Hall sensor senses the rotation of the motor that results in the controller’s output.

Suppose the motor hall sensor damages, and then the dual-mode controller will work well. The non-hall sensor controller shows an error in this case.


Not all speed controllers come with LCD panels. It’s not that you need this necessarily. A bike works without an LCD panel too. But for advanced bikes, users prefer advanced features for adjusting settings. Without an LCD, it’s tough to see and change the settings.


Speed controllers must be light in weight, or else it will just add extra weight to your vehicle. A small box with a smart chip can handle enough functions in one go.

Damage protection

Your motor and battery can be damaged easily. The reason can be low material, overcurrent, or irregular voltage supply. You can fight all of this by using a high-quality speed controller.

Check if:

  • The material used has heat dissipation power or not.
  • The circuit is overcurrent protected or not.

These features are usually mentioned in the product’s specifications.


There are two types of speed controllers, brushed motors or brushless motors. A brushed motor runs faster because of brush and commutators. You can change brushes to extend life.

While a brushless motor lacks a brush and commutators, these are more powerful and durable as there are no brushes to wear down.

Also, brushless motors are more energy-efficient as there are no brushes to rub against each other. Depending on the battery, brushless motors can go 50% longer.


If your ebike speed controller has a lot of wires and connection points, there are high chances that you will fail in installing it. Installation issues occur when you are doing it the very first time.

Some speed controllers are easy to install, and the process is less time-consuming. They come with instructions or labels that help you in this. If still any installation issues persist, connect with the team.


How to choose the best eBike controller?

The voltage rating of the speed controller you are buying should match the bike’s battery and motor. For instance, if the motor voltage says 36 volts, then your controller must be 36 volts too. Not matching with these measurements can damage either the controller or your bike.

What does the speed controller of a bike do?

It is an essential part of any electric bike that helps in controlling speed and other features. This is possible because it is connected with the brake, battery, motor, and throttle. As the name suggests, a speed controller is the main thing that allows you to modify the speed as per your convenience. To start a bike or to stop it, the speed controller is responsible.

What is a throttle in e-bikes?

The throttle may be connected with the thumb or with the pedal. If your bike is equipped with such, it helps you to boost and accelerate. The throttle is a critical factor that allows the bike to propel, and you enjoy a free ride. Thumb throttle will enable you to put immediate brakes.

Are e-bikes worth it?

E-bikes are definitely worth that as it is low cost and energy-efficient. You can use it for any e kind of ground surface, and it offers high-speed movement.

The major plus is it does not harm the environment. Rechargeable batteries can be replaced when they wear down.

Ebikes are beneficial for health as well as for the environment. When compared with traditional bikes, there is no danger. All you need is to use it with adequate care.


An e-bike controller is the heart of the bike. The bike depends on it to perform well so that the bike can function to its fullest potential.

While all the controllers we discussed in the article are suitable, if we were to pick a favorite, it would be the Mophorn Motor With Speed Controller Kit (The controller doesn’t come separately here). It has a high torque motor that can reach speeds of up to 5200 RPMs. It is compact, lightweight, and can be easily fitted to your e-bike. All equipment needed for fitting is provided in the kit.

The Szzijia Speed Controller is a second choice and the most value for our lineup’s money option. Users have given rave reviews for this controller. However, one drawback is that the instructions to use its unique features are not all that clear.
