What Is An Ebike Controller?

Last Updated on November 21 2021 by Matthew

E-bike controller is a device that controls the speed of electric bike. It can be used to control the motor and brake system on your bicycle, so you don't have to pedal it manually anymore.

The E-bikes are becoming more popular in recent years because they offer many advantages over traditional bicycles:

They're easier to ride than regular bikes; they provide better exercise for people who want to lose weight or improve their fitness level; they allow riders to travel longer distances without getting tired; they reduce traffic congestion by allowing cyclists

There are two type of controllers :

  • 6-MOSFET controller

This controller design uses 6 MOSFETs as switches which allows us to turn off/on the power supply to the motor when needed.

This kind of controller has been around since the early 2000's but recently there was some improvements made to them like adding protection circuitry against short circuits etc...

  • 9-MOSFET controller

 This electric bike controller are designed using 9 MOSFETS instead of 6 MOSFETS. This means we get higher current capacity from our circuit compared with other types of controllers.

How to choose the electric bike controller?

There are many other type of controllers design for e-bikes. Some are simple controllers while other are high quality controller.

Here's some more:

  • Dual-mode controller

This advanced controllers are able to switch between different modes depending on what mode you need. They also include features such as battery voltage monitoring, automatic charging cutoffs, and adjustable braking force limits.

The dual mode controller will give you all these benefits at once!

  • Square wave controllers

This controller types have power transistors and protection functions that make sure no damage will happen if something goes wrong during operation. The square waves are very stable and reliable.

  • 15-MOSFET controller

The 15-MOSFET controller is a type of controller has voltage protection circuit and electronic switch function. These kinds of controllers are usually found in professional grade products.

  • 12- MOSFET controller

12-Mosfet controller are cheaper versions of 15-mosfet controllers. 12 mosfets are enough to handle most applications. However, this type of controller may not have any safety protections.

However it have some outgoing e-bike enthusiasts who use them successfully.

  • 18- MOSFET controller

18-mosfet controller have motor power and square wave controller advantage that makes them suitable for both beginners and professionals.

18-mosfet controller is one of the best choices for those looking for good performance and reliability.

  • 36 - 72v eBike Controller

This controller are used for 36V – 72V batteries. It includes three main components:

1) Battery charger 2) Motor driver 3) Power electronics.

It’s easy to install and operate. You just plug into the wall socket and connect the wires. No soldering required.

  • Cheap controller designs

Cheap controller designs are also popular among newbie bikers because they can be easily installed and operated.

But cheap controllers don't offer much functionality so you might end up buying another expensive controller later down the road.

Some examples of cheap controllers are:

1) DC controller.

2) PWM controller.

3) Linear regulator controller.

4) Stepdown converter controller.

5) Boost converter controller.

  • Non-programmable controller

The non-programmable controller have sensor signals that control the speed or direction of your bicycle by adjusting the amount of electricity going through the motor. Non-programmable controllers do not require programming.

Electronic components of e-bikes

The electric components of e-bikes are quite similar to regular bicycles.

There are two major differences though; firstly, there is no chain drive system which means less maintenance and secondly, the motors are connected directly to the pedals instead of being mounted inside the frame like normal bikes.

This allows riders to pedal harder without having their legs break due to strain.

  • Motor size

Most people prefer using larger motors when riding longer distances. Smaller motors tend to get hot quickly and cause discomfort after long rides.

The power unit do the utilization of power voltage from battery pack. This power unit converts the electrical energy stored in the battery pack into mechanical force.

  • Battery capacity

A higher battery capacity gives more range but at the same time increases weight. A lower battery capacity reduces the total distance covered per charge.

  • Battery charger

A battery charger is another important component if you plan to use batteries. There are 2 main types of chargers: trickle charge and fast charge.

The difference between these two is how much energy will go into the battery per hour.

  • Power device driver circuit

This type of electrical components controls the flow of current to the motor. The most common ones include pulse width modulation, constant on/off, triac etc.

  • Brushless DC motors

The brushless motors is a peripheral components that has control functions and throttle conection. They work with electronic circuits to convert direct current into alternating current.

They are very efficient and produce little heat compared to other types of motors. In addition, it's easier to maintain them than brushed motors.

How to connect the electric bike controller?

The electric bike controller consists of two main parts, the battery pack and the controller. Connecting them is easy; simply plug one end into the controller and the other end into the battery pack.

If you are using a lithium-ion battery pack, use a three-pronged charger, such as the ones sold at home improvement stores.

Here's how to connect ebike controller:

Step1. Plug the positive terminal of the battery pack into the red connector on the controller.

Step2. Plug the negative terminal of the battery pack onto the black connector on the controller.

Step 3. Make sure both terminals are firmly attached before connecting the ground cable. Connecting the cables properly ensures safe operation of the controller.

Step4. Turn off all switches on the controller so it does not accidentally turn itself back on while charging.

Connecting the battery pack with the controller can be done easily. However, some users may find this process difficult because they don't know where to start.

What is BLDC e-bike motor?

BLDC or DC in e-bikes are "Brushless Direct Current Motors". These motors have permanent magnets embedded within the rotor rather than electromagnets.

These motors offer several advantages over traditional AC induction motors including increased efficiency, reduced noise, smoother torque curves, and greater durability.

In fact, many manufacturers now claim that BLDCs provide up to 50% better performance than conventional designs.

Hi! my name is Sam Lawrence. I am a 27 year old cycling fanatic. I created this E-BikeReview.UK as a resource for people when shopping for an electric bike. My career in bicycles started when I was a child. I’ve always loved bikes. I started my own bike buying and selling business before I left school and have been running a very successful bike shop in Ledbury (west England) since I was 18 years old.
