How Much Does It Cost to Convert a Bike to Electric?


With the increasing popularity of electric bikes (e-bikes) and their numerous benefits, many cycling enthusiasts are considering converting their traditional bikes into electric ones. Converting a regular bicycle to electric can be an economical and eco-friendly way to enjoy the advantages of an e-bike without breaking the bank. However, the cost of the conversion process can vary significantly based on various factors. In this article, we will explore the components involved in converting a bike to electric and provide insights into the expenses associated with each step.

Understanding the Conversion Process

Before diving into the costs, let’s first understand the basic components required for converting a bike to electric. The main elements of an electric bike conversion include:

1. Electric Motor: The heart of any e-bike conversion is the electric motor. The motor assists the rider by providing additional power to the pedals, making cycling easier and less strenuous.

2. Battery: The battery is the powerhouse of the electric bike. It stores the energy needed to operate the electric motor and determines the range of the e-bike before it needs to be recharged.

3. Controller: The controller is a crucial component that regulates the flow of power from the battery to the motor, allowing the rider to control the speed and acceleration of the e-bike.

4. Throttle or Pedal Assist Sensor (PAS): E-bikes can have either a throttle or a pedal assist sensor. A throttle allows the rider to control the motor power manually, while a PAS senses the rider’s pedaling and provides motor assistance accordingly.

5. Display Unit: The display unit shows important information like speed, battery level, and distance covered. It also allows the rider to adjust settings and monitor the performance of the electric bike.

The Cost Breakdown

The cost of converting a bike to electric can vary based on the quality and specifications of the components chosen. Additionally, labor costs and any specialized tools required for the conversion may also contribute to the overall expense. Here’s a breakdown of the key components and their associated costs:

1. Electric Motor

The cost of the electric motor can range from $200 to $800 or more, depending on factors such as brand, power output, and type. Hub motors are generally cheaper, while mid-drive motors, which offer better performance and efficiency, tend to be more expensive.

2. Battery

Batteries are a significant cost factor in the conversion process. Lithium-ion batteries, known for their energy density and longevity, are commonly used in e-bikes. The price of a battery varies based on its capacity and quality. Expect to spend anywhere from $300 to $1000 for a good-quality e-bike battery.

3. Controller

The cost of an e-bike controller typically ranges from $50 to $200. Higher-priced controllers may offer advanced features and better performance.

4. Throttle or Pedal Assist Sensor (PAS)

The cost of a throttle or PAS can range from $20 to $100, depending on the type and quality. Thumb throttles are generally more affordable, while twist throttles may be slightly more expensive.

5. Display Unit

Display units are priced between $50 to $150. Advanced displays with more features and better visibility may be on the higher end of the price spectrum.

6. Wiring and Connectors

The cost of wiring and connectors is relatively minimal, usually around $20 to $50.

7. Labor Costs

If you are not comfortable with the technical aspects of the conversion process, you may choose to hire a professional to do the job. Labor costs can vary depending on the complexity of the conversion and the rates charged by the technician. Expect to pay anywhere from $100 to $300 for labor.


Converting a bike to electric can be a cost-effective way to experience the benefits of an e-bike without purchasing a brand-new one. The total cost of the conversion primarily depends on the quality of components chosen and whether you opt for professional assistance. On average, a DIY conversion could cost anywhere from $500 to $2000 or more. However, investing in high-quality components and seeking professional help may increase the upfront cost but can lead to a more reliable and enjoyable electric bike in the long run.

Before starting the conversion process, thoroughly research the components and their compatibility with your existing bike. Additionally, consider your budget, riding needs, and technical skills when making decisions. With the right approach, converting your bike to electric can be a rewarding and cost-efficient way to embrace the world of e-bikes and enjoy a greener mode of transportation.
