DIY Enthusiasts: Which Motor Suits You Best for your pedelec?

Embarking on the journey of building your own electric bike is not only a practical endeavor but also an adventure in innovation and customization. One of the key decisions you'll face in this DIY project is choosing the right motor for your self.

In this guide, we'll mainly explore the Mid drive Motor & Hub Motor differences to help you make an informed decision. Whether you prioritize balance, handling, affordability, or simplicity of installation, we're here to guide you through the decision-making process and set you on the path towards creating your ideal electric bike.

  • 1. Mid-drive Motor vs. Hub Motor: Basic Concepts

Mid-drive Motor: The mid-drive motor is installed at the bottom bracket of the bicycle and is typically connected to the bicycle's gears through the drivetrain. It provides power by driving the chain directly, which contributes to a more balanced weight distribution and helps maintain the bike's stability and handling.
Hub Motor: The hub motor is installed directly inside the bicycle wheel hub. It delivers power directly to the wheel, propelling the bicycle forward. The hub motor's design is simpler and its installation is easier, making it suitable for DIY projects.
  • 2. Advantages and Disadvantages of Mid-drive Motor


Balance and Handling: Due to its position at the bottom bracket, the mid-drive motor maintains the bike's balance and enhances stability, resulting in better handling.
Utilization of Gears: The mid-drive motor can work in conjunction with the bicycle's gears, allowing for adjustments in gear ratios to provide varying levels of power support, suitable for different riding environments and needs.

Complex Installation: Installing a mid-drive motor may require more specialized tools and skills, including disassembling and reassembling the bicycle's drivetrain.
Higher Cost: Mid-drive motors typically come at a higher price point compared to hub motors, which may increase the overall cost of the DIY project.
  • 3. Strengths and Weaknesses of Hub Motor

Easy Installation: Hub motors are relatively easy to install, requiring only placement inside the wheel hub without the need to involve the bicycle's drivetrain.
Affordability: Hub motors generally come at a lower price point, making them suitable for DIY projects with budget constraints.
Slightly Reduced Balance: Due to the concentrated weight on the wheel, hub motors may result in slightly reduced balance, especially noticeable at low speeds.
Limited Gear Utilization: Hub motors cannot work with the bicycle's gears, potentially limiting performance on steep inclines or situations requiring higher torque.
  • 4. Choosing should Be Based on Personal Needs

Mid-drive motors are ideal for those prioritizing bike aesthetics, balance, and handling or those confident in their DIY skills. Hub motors are suitable for individuals seeking simple installation, affordability, and are less concerned about bike aesthetics.
  • 5. Considering Other Factors

Besides motor type, factors such as cost, installation complexity, DIY skill level, and personal riding preferences should also be considered when making a decision.

In summary, both the mid-drive motor and the hub motor have their own advantages and disadvantages. The mid-drive motor offers better balance, handling, and full utilization of the bike's gearing system, but comes with a more complex installation process and higher cost. Conversely, the hub motor provides a simpler installation and is more budget-friendly, although it may slightly affect the bike's balance and cannot fully utilize the gearing system. Therefore, the choice depends on individual preferences and needs. We encourage readers to weigh the pros and cons carefully and make an informed decision based on their circumstances.
