Choosing an EBike Kit

Electric bikes have been gaining a lot of popularity among hobbyists, sport riders, and commuters. Advances in electric motor technology and the availability of more powerful rechargeable batteries have led to a new era of super high performance, battery powered bicycles. You can get the best of both worlds by choosing the model and make of bike that you prefer and then converting it into an e-bike for the convenience factor.

One of the things that is exceptional about electric bicycles is that you get all the benefits of a traditional bicycle, but you can also go longer distances and faster without putting in so much effort. Many people prefer electric bicycles because commuters and others can get where they need to be without getting sweaty or hot.

The easiest method of owning an electric bike is simply to buy one that comes complete. Bicycles built for be e-bikes are designed around the battery and motor that are required. However, the extra engineering, research, development, and marketing can push the price of these bikes up. Not everyone wants to pay the huge price for an electric bicycle.

If you prefer to save a ton of cash, it’s possible to take your already existing bike and turn it into an electric bicycle. There are a couple of options for doing this. The first is to go out and purchase each of the components you will need and then assemble everything together.

This will require you buying a motor with a throttle, a battery, a controller, and the required wiring to put it all together. In addition to that, you are going to need a dose of technical expertise to put everything together in the safest possible way. This is going to be the least expensive way to convert your bike, but it is also the most challenging.

Your final option for converting to electric is to purchase an electric bike kit which is going to come with all the parts you need. The electrical work has been taken care of, so your only task is to fit the kit onto your bicycle. Anyone with a bit of time, simple tools, and a basic knowledge of bike mechanics can handle it.

Types of Electric Bike Kits

There are a lot of things that go into adding an electric motor to your bike for power. This also means that there are many different kinds of conversion kits that you can choose from. One of them might be a better option for you than another, so it’s worth being aware of your various options.

E-Bike Wheels Conversion

The most common type of electric bicycle kit you will see on the market is an e-bike wheel. The front or the rear wheel of an existing bike is replaced by a special wheel that includes a unique hub and gearing. The battery is sometimes included in the hub or it may be mounted in another location.

If the kit has a battery mounted elsewhere, a motor on the front wheel works well for road riding as the kit weight is distributed across the entire bike. If the entirety of the weight of the ebike kit is on the front wheel, it can make steering more difficult.

It’s also worth considering how strong the fork of the bike is because electric motors can create a large amount of torque. In most cases, you will need a bicycle stronger than a road bike to mount a motor to the front wheel.

Rear wheel motors tend to work best for use off-road as it provides the best traction. However, those who have a hub gear currently on their bike will be required to replace it with a derailleur and cassette. The best option for the battery is one that is external and can be mounted on a frame.

Mid-Drive Conversion 

A mid-drive conversion takes the design of a complete electric bike and mimics it. With this sort of ebike conversion kit, the motor and battery are both mounted to the bike frame, often with the bottom bracket holding the motor. This keeps the weight down low for better ride feel but it also makes it most likely to be damaged.

Friction Drive Conversion

This version of e-bike conversion kit has a motor and a roller which both sit on the rear wheel so that friction can propel the bike forward. This isn’t the most popular option and is a cruder solution than others. The system isn’t very efficient and has weight distribution issues.

Concealed Conversion

This is a more expensive option, but it appeals to anyone who might have a reason to conceal that they are using an electric bicycle. With this design, the electric bike motor and battery both fit inside of a seat tube which goes into the bottom bracket. This is going to be extremely expensive and should only be considered by those who want to hide that they own an electric bike.

Power, Capacity, and Range

Now that you have an idea of the different electric bicycle conversion kits, you also want to consider the technical details of the e-bike kit you might consider purchasing. There are a lot of numbers and it can be confusing to know which to pay attention to. We’ll share what to know and why below.


When you look at an electric motor for a bicycle, you’re going to see that they boast having 250 watt, 500 watt, 750 watt, and so on. This number corresponds to how much power the motor can output. The higher the stated number, the more power the motor can offer. However, a higher wattage also means you will need a larger and more powerful battery.


Electric bike motors are powered by a battery, typically a lithium-ion version. You want to choose a battery voltage that matches the voltage from the motor. The most common voltages on e-bike conversion kits are 24V, 36V, and 48V.

Amp Hours

Amp hours refers to the amount of energy that a battery holds which can be extracted and is also called the capacity. A battery that has a higher capacity is capable of running longer so you can ride a longer distance. Most conversion kits range from 8 to 20Ah.

The amount of power and the total capacity that you need with your electric bike conversion kit with battery will depend on how you use your bike. Those who commute short distances on flat roads may only need a small motor and a less powerful battery. Those who ride off-road will want a higher capacity battery and a more powerful motor.

However, make sure you look at local laws regarding use of electric bicycles on the road. Sometimes there are power or speed restrictions.

What a Controller Is

The electric bicycle conversion kit you choose may come with a controller. This component offers a display where you can see information about your speed, power output, battery level, and more. Most cyclists consider this a must-have accessory. Even if you get one that only shows your battery level, it will make riding easier.

Those who plan to do a lot of biking may want to choose one with additional display options to ensure a smooth ride.

Throttle or Pedelec Component

You should always take a look at whether an electric bike motor kit comes with a throttle, pedal assist, or both. If it has a throttle, getting power involves simply pressing a button or twisting and there is no need to use your own leg power. Those with pedal assist will engage the motor as they pedal along.

About Brake Levers

In some kits, you’ll find an included brake lever that you can apply to cut power to the bicycle. This prevents you from both braking and acceleration at the same time. However, these levers are only compatible with cable actuated brakes. Those who have hydraulic disc brakes may be able to find sensors that can do the exact same thing.

Putting it Together

Now that you know which are the best electric bicycle kits, you can browse until you find that one that offers what you need. If there isn’t the perfect option listed, use our buyer’s guide to find one elsewhere. You will be ready to enjoy some stress-free, super-efficient cycling in no time!
