DIY Electric Bicycle Conversion: What You Need to Know

What is Electric Bicycle Conversion?

Before we dive into the nitty-gritty details, let’s make sure we’re all on the same page. Electric bicycle conversion is the process of turning a regular, pedal-powered bike into an electric one by adding an electric motor and battery. This allows you to ride your bike with an extra boost of power, making it easier to climb hills or ride longer distances without getting tired.

Choosing the Right Components

When it comes to electric bicycle conversion, choosing the right components is crucial. Here are the main things you’ll need to consider:

Electric Motor

The electric motor is the heart of your electric bike conversion. It’s what will provide the power to move you forward without pedaling. There are two main types of electric motors: hub motors and mid-drive motors.

  • Hub motors are located in the wheel hub and are easier to install, but they can make your bike feel unbalanced.
  • Mid-drive motors are located near the bike’s bottom bracket and provide better balance, but they can be more complex to install.

For most DIY electric bike conversions, a hub motor is the way to go. They’re easier to install and require less maintenance.


The battery is what powers the electric motor. You’ll need to choose a battery that’s the right size and capacity for your bike and your riding needs. Lithium-ion batteries are the most common type used in electric bike conversions, as they’re lightweight and have a high energy density.


The controller is what connects the battery to the motor and allows you to control the speed and power of your electric bike. Make sure to choose a controller that’s compatible with your motor and battery.

Other Components

In addition to the motor, battery, and controller, you may also need other components such as a throttle, display, and wiring harness. Make sure to choose components that are compatible with each other and with your bike.

Installing the Components

Once you’ve chosen your components, it’s time to install them on your bike. This can be a bit tricky, so if you’re not comfortable working on your bike, it’s a good idea to take it to a bike shop or find a friend who can help you. Here’s a general overview of the installation process:

  1. Remove the wheel from your bike and install the motor in the hub.
  2. Install the battery on your bike, either on the frame or in a bag attached to the frame.
  3. Connect the battery to the motor using the controller and wiring harness.
  4. Install the throttle and display on your handlebars.
  5. Test your electric bike to make sure everything is working properly.

Pros and Cons of DIY Electric Bicycle Conversion

Like anything, DIY electric bicycle conversion has its pros and cons. Here are a few to consider:


  • Cost-effective: DIY electric bicycle conversion is often much cheaper than buying a new electric bike.
  • Customizable: You can choose the components that best suit your needs and preferences.
  • Eco-friendly: Electric bikes are a more sustainable mode of transportation than cars or motorcycles.


  • Safety: Installing the components yourself can be dangerous if you’re not familiar with bike mechanics or electricity.
  • Warranty: If you’re not an expert, you may void the warranty on some of the components you’re using.
  • Time-consuming: The installation process can be time-consuming and requires some patience.

Frequently Asked Questions (FAQ)

Here are some common questions people have about DIY electric bicycle conversion:

1. How fast can an electric bike go?

The speed of your electric bike will depend on the power of your motor and the capacity of your battery. Most electric bikes can go up to 20-28 mph (32-45 km/h).

2. How far can an electric bike go on a single charge?

Again, this will depend on the capacity of your battery and the power of your motor. Most electric bikes can go between 20-50 miles (32-80 km) on a single charge.

3. Can I still pedal an electric bike?

Yes! Electric bikes still have pedals, so you can pedal like a regular bike if you want to get some exercise or conserve battery power.

4. Do I need a special bike for electric conversion?

No, you can convert almost any bike into an electric one as long as it’s in good condition and can support the weight of the components.

5. Is electric bike conversion legal?

In most places, yes, as long as your electric bike meets certain requirements, such as a maximum speed limit and power output. Make sure to check your local laws and regulations before converting your bike.


DIY electric bicycle conversion can be a fun and rewarding project, but it’s important to do your research and choose the right components for your bike and your riding needs. Remember to always put safety first, and if you’re not comfortable working on your bike, seek the help of a professional. Happy riding!
