Introduction to E-Bike Conversion Kit

When most people hear the term “electric bicycle,” the first thing that comes to mind is a scooter or an electric motorbike, but they are not the same thing. Consider a standard bicycle, then add various electrical components such as a motor, a battery, and a controller – all of which are smoothly incorporated into the design. These components are the foundation of all electric bicycles on the market!

This new technology Hub Motor DIY Conversion Kit is designed explicitly for Electric Bike Bicycle. This innovation is used for converting your vehicle or cycle into Electric Bicycle.  These are better quality quads and scooters on the market and are classed as a mid-range combination.  A variety of components such as E-bike. Motor, controller, battery, throttle, brake, and mechanical components are necessary to build an E-bike. In this tutorial, we will go through each component’s usage in depth.

E-bike Motor

The Electric motor converts electrical energy from the battery into mechanical power to operate the bike. Electric bike motors are available in a broad range of power ratings, ranging from 200W to 1,000W or more. A higher grade indicates that the bike can lift more weight with greater ease – but at the price of utilizing more battery power in the process. As a result, a 750W motor will deplete the battery faster than a 250W motor, but it will be more powerful.

The most common type of motor for electric bikes is called a hub motor. It is generally integrated into the rear or front wheel. When engaged, it pulls or pushes the wheel along. Although this system works well, it has one key disadvantage. Since it is not connected to the bike’s gears, it loses efficiency on hills and varied terrain. Imagine driving a vehicle in just one gear the entire day. It will get you places, but it won’t give you the optimum amount of torque or speed that you get with a full gear range.

This motor is capable of rotation in both, clockwise or counter-clockwise directions by reversing the motor’s power wires. The purpose of moving a motor is to control speed and torque.  The Hall effect sensors detect the position of the rotor, also used to detect speed by measuring the time  takes for the sensors to switch.

E-bike Motor Controller

The Motor Controller is a crucial component of an E-bike since it controls the E-bike motor. The majority of E-bike motors are brushless and have three wires. This alternating current is required for the brushless motor to rotate. At motor speeds corresponding to cycling speeds ranging from zero to 48 km/h, an electric bicycle controller must supply power ranging from zero to the rated peak of the propulsionmotor (30 mph). Power may be adjusted by pulse-width modulated (PWM) transistors in DC propulsion motors.

This motor controller ensures steady speed and sensitive control of braking and direction changes in an electric bike bicycle. The controller body/shell is made up of a high-quality aluminum alloy that protects the inner circuit. Hence this premium shell is good for heat dissipation to avoid thermal overloading. Meanwhile, the controller wires and interfaces offer high durability, thereby ensures malfunction of long time use. Moreover, it provides a Current limiting feature that prevents controller and motor damage due to over-current conditions. The controller board comes with attachments for the motor, accelerator, brake, battery, brake light, power lock.

. Moreover, this controller features:

  • Anti-coaster and over-current protection
  • Automatic identification of the 36V and 48V
  • Automatic identification of the Hall sensor
  • Phase angle identification of 60 degrees and 120 degrees

Pedal-activated controls provide electric assistance when you depress the pedals. A controller positioned on the handlebar in pedal-activated systems allows you to regulate the degree of assistance based on your pedaling.

Throttle-based controllers use a straightforward throttle mechanism. It functions as a potentiometer. The throttle might be of the twist-grip or thumb-press kind. With a throttle, you may obtain electric assistance by pulling back or pressing the throttle.

E-bike Battery

Electric bike batteries are meant to have a high quantity of storage since they discharge while the bike is used, and they should be able to survive repeated discharging and deep cycles. The battery powers the engine and motor in electric bikes. Before purchasing an electric bike battery, a client should consider the brand, AH, and number of volts necessary.

E-bike Throttle

Throttle controls the total amount of power delivered by the electric motor at any one time. A throttle input plug is found on almost all motor controllers. A throttle is similar to a motorbike throttle. The electric motor, which is usually positioned on the handlebar and operated by twisting, may provide power without requiring any pedalling at all.

Some bikes just have a throttle and no pedal assist mechanism, while others have the choice of using either pedal assist or throttle. Some ebikes do not have pedals at all, instead relying only on a throttle. Bikes with a throttle and pedal assist may have a throttle disable option, or they may be able to work with the throttle totally disconnected and/or removed from the bike.

To detect the throttle position, all throttles employ hall sensors and a magnet. They also give 0.8-0.9V when the throttle is turned off and 3.6-4V when the throttle is turned on. Thumb or lever throttles are the two most prevalent types of throttles used in E-bikes. Thumb press throttles are activated by pressing the thumb on a paddle, whereas twist-grip throttles are activated by turning the handgrip.

E-bike Brake or E-brake

E Brake is a critical component in the design of an ebike’s “fail safe” safety mechanism. When the rider applies the brakes, the E Brake sensor detects it and sends a signal to the controller, preventing the engine from rushing ahead. Only professional factory-built ebikes come complete with front and rear brakes.There are two reasons why an E-bike should include an E-brake sensor. One is for the safety cut-off; when you push the brake levers, the motor will turn off.

E-bike Mechanical Components


Mechanical components and characteristics that serve as the foundation of an E-bike. The sprocket, pinion, chain, and freewheel are all part of it. Let’s have a look at how each one may be put to use.


The Freewheel on an e-bike allows you to keep your bike pedals motionless or pedal backwards while pedalling. Your rear wheel is equipped with freewheels. The Freewheel acts as an automated clutch, allowing you to change speeds in a manual transmission without having to push the clutch pedal.

The E-freewheel bike allows you to keep your bike pedals motionless or pedal backwards while pedaling. Freewheels are simple to install on your back wheel, but make sure your electric bike’s rear wheel is appropriate. This 16-tooth freewheel is suitable for Fixed Gear Bikes, Bike Tryalls, and other similar applications.


The usage of a rear engine and pinion gearbox combination gives a pleasant riding experience with minimal influence on the drive. The rider’s propulsion effort should ideally be routed through the centre Pinion gearbox and then augmented as needed by an electric motor.


They are spinning teeth-bearing components. To transmit torque, a sprocket can be used in conjunction with a chain and another sprocket. Sprockets and chain are used in an E-bike to adjust the speed, torque, or direction of a motor, but their thickness and pitch must be the same.


It is a roller chain that transmits power from the pedals to the drive-wheel of an E-bike, allowing it to go forward. The chain provides an effective flow of electricity, resulting in a longer battery life. These chains are intended to increase the efficiency and range of electric bikes. The enhanced wear potential is caused by the mid-motor, which improves the rider’s power and torque. As a result, the chain transmits these larger loads straight to the cassette. As a result, the chain assures effective power transmission as well as sustained and extended battery life.


Electric bikes can assist riders of all ages, skill levels, and physical capacities lead more active lifestyles, but they are not without flaws. Being aware of the benefits of ebike use, as well as some of the problems associated with purchasing and operating an ebike, will make you a well-informed, knowledgeable consumer, ready to make the best possible decision when it comes time to pick and purchase your own ebike.
