Powertrain
Let us understand first what is the powertrain—the most commonly used word in all kinds of automotive vehicles.
In very simple words, the powertrain is a joint effort of the entire mechanism of the vehicle which propels the vehicle to move forward.
Nowadays, electric vehicles are becoming more popular than ever before, and electric two-wheelers are at the forefront.
These vehicles are comparatively small, agile, and eco-friendly, making them perfect for urban mobility.
Interestingly, among electric two-wheelers, one of the key factors that make electric two-wheelers so appealing is their powertrains. Electric powertrains are simple, efficient, and reliable.
Moreover, they also offer multiple advantages over traditional gasoline engines, such as lower emissions, lower noise, and lesser maintenance costs.
In this blog post, we will take a closer look at electric two-wheeler powertrains. We will also discuss the different components of a powertrain, how they work, and the advantages they offer.
So, if you are interested in learning more about electric two-wheeler powertrains, then this post is for you!
What is a Powertrain
A powertrain is a system that converts fuel or other energy sources into mechanical energy to power a vehicle.
In the case of electric two-wheelers, the powertrain consists of three main components: the electric motor, the battery pack, and the electronic control unit (ECU).
The electric motor is responsible for converting electrical energy into mechanical energy, which is further used to drive the vehicle’s wheels.
Notably, the battery pack serves as the energy reservoir that powers the motor. The ECU(controller) acts as the brain of the powertrain, regulating the flow of electricity and managing various aspects of the vehicle’s performance.
Types of Electric Two-Wheeler Powertrains
There are two main types of electric two-wheeler powertrains: hub motor powertrains and mid-drive powertrains.
Hub motor powertrains
Hub motor is integrated directly into the wheel hub.
This configuration offers a simple and compact design, resulting in reduced maintenance and increased efficiency.
Thus, hub motor powertrains are popular in electric scooters and smaller motorcycles.
Mid-drive powertrains
In a mid-drive powertrain, the electric motor is positioned at the centre of the frame, typically near the bottom bracket.
Resulting, this design provides better weight distribution and improved handling, making it ideal for electric mountain bikes and high-performance motorcycles.
Working Principle of Electric Two-Wheeler Powertrain
The operation of an electric two-wheeler powertrain can be summarized in a few key steps:
- The battery pack supplies electrical energy to the electric motor through the ECU(controller).
- The ECU regulates the power output based on the rider’s input and the vehicle’s requirements.
- When the rider engages the throttle, the ECU sends a signal to the motor, causing it to rotate.
- As the motor spins, it generates torque, which is transferred to the wheels through a transmission system or directly in hub motor designs.
- The charger is used to recharge the battery. It converts electrical energy from the mains into electrical energy that can be stored in the battery.

FAQ
What is an electric two-wheeler powertrain?
A powertrain in an electric two-wheeler refers to the system that connects the electric energy source (battery pack) with the mechanical energy needed to drive the wheels.
It includes the electric motor, battery pack, and electronic control unit (ECU) that manages the flow of electricity and controls the vehicle’s performance.
How does the powertrain in an electric two-wheeler work?
The powertrain operates by receiving electrical energy from the battery pack, which is then sent to the electric motor through the ECU.
When the rider engages the throttle, the ECU signals the motor to rotate, generating torque that drives the wheels and propels the vehicle forward.
How far can electric two-wheelers travel on a single charge?
The driving range of electric two-wheelers varies depending on factors like battery capacity, vehicle weight, terrain, and riding style.
