Why Convert Your Mountain Bike to Electric?

There are several compelling reasons to consider converting your mountain bike to electric, which can enhance your cycling experience in various ways:

  • Increased range: An electric mountain bike enables you to cover more significant distances with ease, expanding your exploration possibilities and allowing you to enjoy more of the great outdoors.
  • Tackling steep terrain: The additional power from an electric motor empowers you to conquer challenging hills without exhausting yourself. This feature is particularly useful for off-road enthusiasts who want to tackle demanding trails.
  • Reduced fatigue: Electric assistance takes some strain off your legs, helping you maintain your energy levels throughout longer rides. This benefit can be especially helpful for those recovering from injuries or simply wanting to enjoy a more leisurely ride.
  • Cost-effectiveness: Converting your existing mountain bike to electric is often more affordable than purchasing a brand-new electric mountain bike. This option allows you to enjoy the benefits of an e-bike without breaking the bank.
  • Customization: By converting your mountain bike, you have the flexibility to choose the components that best suit your needs and preferences. This freedom allows you to tailor your e-bike to your riding style, ensuring an optimal experience.

Understanding the Components of an Electric Mountain Bike

Converting your mountain bike to electric requires the following components:

  1. Motor: The motor provides the electric assistance and is typically mounted on the rear wheel, front wheel, or in the center of the bike as a mid-drive motor. Each motor type has its advantages and drawbacks, so choose the one that aligns best with your riding preferences.
  2. Battery: The energy source for the motor is usually a lithium-ion battery. These batteries come in various capacities, with larger capacities offering longer ranges. However, larger batteries can also be heavier and more expensive. Consider your typical riding distances and terrain when selecting a battery.
  3. Controller: The controller manages the power delivery from the battery to the motor. It should be compatible with both your motor and battery. Some controllers offer programmable features, allowing you to fine-tune the power delivery to suit your preferences.
  4. Display: A display screen provides essential information such as battery life, speed, and assist level. Displays come in various styles, from basic LED indicators to full-color screens with advanced features like GPS navigation. Choose a display that offers the information you need and is easy to read while riding.
  5. Throttle (optional): A throttle device enables you to control the motor directly without pedaling. This option can be helpful for those who want more control over their electric assistance or need a boost to start from a standstill.

Selecting the Right Components for Your Electric Mountain Bike

Before starting the conversion process, it’s essential to choose the appropriate components for your needs. Here’s what to consider:

  1. Choosing the Right Motor: The three main types of motors are hub motors (mounted in the wheel), mid-drive motors (mounted near the pedals), and friction drives (mounted on the rear tire). Each has its advantages and drawbacks. For mountain biking, mid-drive motors are the most popular choice due to their excellent power, efficiency, and ability to maintain a natural bike feel.
  2. Selecting the Ideal Battery: Battery capacity, measured in amp-hours (Ah), determines the range of your electric mountain bike. A higher capacity battery will provide a longer range but also be heavier and more expensive. Consider your typical riding distances and terrain when choosing a battery. Additionally, ensure that the battery is compatible with your chosen motor and controller.
  3. Picking the Appropriate Controller: The controller manages the power delivery from the battery to the motor. It should be compatible with both your motor and battery. Some controllers offer programmable features, allowing you to fine-tune the power delivery to suit your preferences.
  4. Deciding on a Display: Displays come in various styles, ranging from basic LED indicators to full-color screens with advanced features like GPS navigation. Choose a display that provides the information you need and is easy to read while riding.

Step-by-Step Guide to Converting Your Mountain Bike

Once you’ve selected your components, follow these steps to convert your mountain bike into an electric mountain bike:

  • Preparation: Remove any accessories and clean your bike thoroughly. This will give you a clear workspace and ensure a smooth installation process.


  • Installing the Motor: Depending on the type of motor you’ve chosen, installation will vary. For a mid-drive motor, you’ll need to remove the bottom bracket and chainset, then install the motor in its place. For hub motors, you’ll need to replace the existing wheel with the motorized wheel.
  • Setting up the Battery: Attach the battery mount to the frame, typically on the downtube or rear rack. Secure the battery to the mount and connect it to the motor and controller.
  • Connecting the Controller: Mount the controller in a safe, secure location on the frame, away from moving parts. Connect it to the motor, battery, and display.
  • Mounting the Display: Attach the display to the handlebars, ensuring it’s easily visible while riding. Connect it to the controller.
  • Adding a Throttle (optional): If you’ve opted for a throttle, install it on the handlebars and connect it to the controller.
