how to convert bicycle into electric bicycle

It’s clear to see that electric bikes are gaining popularity rapidly around the world and more people are getting the e-bike fever each passing day. While some prefer to purchase a ready-made electric bike from popular brands, many people choose to convert their own bicycles to e-bikes, using the DIY method. In this article, we will show you exactly how to convert bicycles into electric bikes.

Converting a normal bicycle into an electric bike involves a few steps which can seem complicated if you don’t have the right resources. Luckily for you, this article will breakdown each step to make the conversion process as simple as possible.  

Converting a bicycle into an electric bike starts with deciding on the type of e-bike you want. The choices you have include the pedal assist e-bike, the throttle assists e-bike and the speed pedelec e-bike. While the steps involved in converting a bicycle into these classes of e-bikes might look similar, there are some distinctions in each of e-bike type.

Pedal Assist

The pedal assist e-bike is the most common category of e-bikes in the industry. It is designed to allow the rider to pedal the bike like a normal bicycle. However, while the rider is pedaling, a motor in the bike assists his efforts to boost the power that is transmitted to the wheels, thereby providing more speed and reducing the pedal effort required to move the bike.

Throttle Assist

The throttle assist e-bike works more like the motorcycle or scooter, where there is no need for pedaling the bike. Instead, the bike is moved by a power supplied by a throttle in its motor. The throttle assist e-bike is not as popular as the pedal assist technology, but many people prefer to use them.

Speed Pedelec

The speed pedelec e-bike is like the pedal assist bike. The distinction is the function that allows the bike to run at a faster speed while being pedaled, just as suggested by the name. Many communities and countries require licenses from riders of this e-bike category, as it is often considered as a motor vehicle.

The processes to converting your bicycle to one of these e-bike types are all distinct.

Things To Consider Before Converting Your Bike

Consider the questions below before you move forward in converting your bicycle into an electric bike.

To successfully convert your bicycle into an e-bike, you must consider a few factors including the type of e-bike you want, the e-bike motor type, the bike style, the e-bike battery type, and the use of the e-bike.  

What type of electric bike do you want?

As we just discussed in the section above, you can choose between three different categories of electric bikes. You should study these types of e-bikes and their features to determine which one would suit your needs.

What is the best e-bike motor for you?

The e-bike motor is the electric engine that moves the bike or assists the bicycle pedals in moving it. There are different types of e-bike motors. Understanding the distinction between these motor types will help you make an informed decision.

Here are the types of e-bike motors you should know:

Hub Motors are often placed in the front or the back of the bicycle. This motor functions to drive either the front wheel or the rear wheel of the bike. This type of e-bike motor is quite popular and it is further classified into the front hub motor and the rear hub motor.

Mid-Drive Motors are usually placed in the middle of the bike frame, just around the engine area. It drives the chain of the bicycle, instead of its wheels, and it is much more efficient in balancing weight across the bicycle and carrying heavier loads.

How will you use your e-bike?

Before converting your bicycle to an e-bike, think about how to plan to use it. What do you intend to use the e-bike for after conversion? There are several reasons why people want an electric bike, from commuting to work, hunting, riding uphill, or just for leisure. You must decide the purpose of your e-bike before you convert it.
