How to choose an electric motor for a motorcycle?

2023-04-19 16:47:00

Electric motorcycles, or e-motorcycles, have become increasingly popular in recent years, mainly due to their environmental benefits and cost-efficient operation. Whether you are planning to build an e-motorcycle from scratch or upgrade an existing one, choosing the right electric motor is paramount. In this comprehensive guide, we will explore the key factors you should consider when selecting an electric motor for your e-motorcycle.

Power Output

The first factor to consider is the power output of the electric motor. The motor's horsepower directly impacts the speed, acceleration, and climbing ability of your e-motorcycle. A higher horsepower motor will offer superior performance, allowing for quicker acceleration, increased speed, and the ability to tackle steeper inclines.

However, it's important to remember that a more powerful motor often comes with a higher price tag. Therefore, it's crucial to strike a balance between power and cost, ensuring the motor you choose aligns with both your performance requirements and budget.

Motor Type

The type of motor you choose for your e-motorcycle is another essential factor to consider. There are several motor types suitable for e-motorcycles, including brushed DC motors, brushless DC motors, and induction motors. Each of these motor types offers its own unique benefits and drawbacks.

Brushed DC motors, for instance, are relatively straightforward and cost-effective, making them an excellent choice for entry-level e-motorcycles. On the other hand, brushless DC motors are more efficient and better suited for high-performance e-motorcycles, albeit at a higher cost. Understanding the specific advantages of each motor type can help you make an informed decision that best suits your needs.

Size and Weight

The size and weight of the electric motor are also factors that can significantly influence your e-motorcycle's performance and ease of installation. Larger, heavier motors can generate more power but might be more challenging to install and could negatively affect the overall weight distribution and balance of the motorcycle.

In contrast, smaller, lighter motors might be easier to install and could yield a more agile motorcycle. However, they may lack the power output seen in their larger counterparts. Therefore, you must consider the implications of motor size and weight on both the installation process and the overall performance of your e-motorcycle.


In conclusion, choosing the right electric motor for your e-motorcycle involves a careful balance of power, cost, size, and weight. By considering your specific needs and preferences and aligning them with your budget, you can select an electric motor that optimally meets your requirements. Remember, the perfect motor for your e-motorcycle is one that complements your riding style and enhances your overall riding experience, all while staying within your budget.
