How Much Does Bike Conversion Cost?

According to Statistica, the e-bike market will grow by 12.27 percent annually from 2022 to 2027. If you are part of the 12.26 percent, you might think buying a brand-new electric bike is convenient. You can ride your battery-supported bike as soon as you get it. 

However, some people find it more appealing to convert their old bike to electric despite all the work it requires. On top of that, converting a standard bike to an electric is one of the least expensive ways to have an e-bike. 

But how much does converting a standard bike into an electric bike cost?

The Cost Of Converting A Conventional Bike To An Electric

Converting a conventional bike to electric requires a bike conversion kit. Such a kit typically costs $300 to $900. 

Still, the actual cost of converting a bike to electric depends on the motor and battery included in the kit you are planning to purchase. Some motors allow you to control the bike better on challenging trails. In contrast, others offer incredible speeds for long-distance rides. 

Apart from the kit you will purchase, the price of converting your old bike to an electric one depends on how you intend to use the bike. For instance, those who plan to use an electric bike for commuting may opt to install an average motor to the bike they will convert. As commuter e-bikes only tackle flat terrains, you do not need the high-end features that expensive e-bike motors offer.

On the other hand, mountain bikes will benefit from high-end conversion kits with powerful motors. The reason is that such bikes must tackle rough, obstacle-filled trails with ascents and descents.

Suppose you plan to convert your MTB to an electric one. Then, spending on an expensive conversion kit with a good motor and long-lasting battery will provide you with the needed e-bike features.

Bike Conversion Kit Recommendations

Bike conversion kits are increasingly becoming appealing to people who want to own an electric bike but cannot let go of their good old standard bike.

What Do You Need To Convert A Bike To Electric?

An electric bike is a standard bike powered by a motor and a rechargeable battery. Apart from electrically powered parts, all the other parts of an e-bike, such as the frame, handlebar, and drivetrain, are the same as the conventional one. Considering this fact, you might be wondering what you need to install on your bike to make it electrically powered.

According to a study conducted by UPPSALA University students, the standard motors used on electric bikes are direct current (DC) and brushless direct current (BLDC) motors. However, bike conversion kits offer two types of motors:

  • Hub Motor System – this motor type is the easiest installation option. You will commonly see this motor type in entry-level bike conversion kits. You can install it on the front or rear wheel, giving your bike a new range of power levels. 
  • Mid-Drive Motor Systemthis motor needs to sit at the cranks of your bike. So, it makes the front chainring and rear wheel work more efficiently by supplying them with power through the bike’s chain. This motor is ideal for people who want to convert an off-road bike to an electric one. 

The reason is that a mid-drive motor can supply a bike’s drivetrain with more power, which you will need for tackling obstacles and steep trails. However, it is worth noting that this motor requires you to change your cranks. It will also wear the drivetrain faster than a hub motor.

Some kits offer 1000W of motor power, but you must first check your local laws before installing it into your bike. For instance, the Federal Register states that electric bikes in the US should not have more than 750W of power.


Your electric bike needs a power source to run in pedal-assist mode. Usually, bike conversion kits have batteries ranging between 250W to 500W with 36V to 48V.

Ideally, you want your electric bike to have a lithium-ion battery with a minimum rating of 36V and 10Ah. Such a battery will let you reach 20 miles at throttle mode and 40 miles using pedal assist.

But if you are in for a long ride, you can opt for an e-bike battery with 36V, 17Ah, and a 500W motor. This battery power will let you reach 60 miles on pedal assist and 30 miles on throttle mode.

However, it is essential to note that your weight, terrain, and additional load weight will affect how far an e-bike battery will allow you to go.

More eBike Battery Information


An electric bike controller is responsible for getting energy from the battery and transferring it to the motor. The power it directs to the motor depends on the user’s inputs.

The controller also monitors an array of data, such as the battery’s voltage, motor power, and bike speed, among other things.

Once you have installed a control unit into your bike, you will be able to control the following:

Speed Sensor

As the name suggests, a speed sensor measures the speed of your converted bike, allowing you to see how fast you are going. It also lets you switch the bike’s motor off to slow your pace. 

For instance, the National Conference Of State Legislatures states that e-bikes should not exceed 20mph when running on the throttle on commuter roads. You can use the speed sensor to ensure that you are not running faster than this speed limit.

The speed sensor is compact and consists of an induction contact and magnetic steel ring. The magnetic ring connects to your converted bike’s crank, which allows it to pick up and transfer speed measures and information on your display monitor.

A display monitor or LCD/LED screen is precisely what it sounds like – a small screen that displays all the data you need to know about your e-bike. For instance, you can see your speed and battery left on the screen. You can also use it to control the bike’s settings, including the backlights, headlights, pedal-assist, or throttle mode.

Some display monitors also have an odometer, which allows you to see how many miles you have traveled.
