What Are The Best Electric Bicycle Conversion Kits? (2020)
Electric bicycles continue to grow in popularity. Not only are these battery-powered two-wheelers a more economical way to get around than cars and motorcycles, but they are also very environmentally friendly.
Electric bikes are also very adaptable. You can pedal them like a regular bicycle or use the motor like a battery-powered scooter. You can also adjust the power ratio to get assistance from the engine to tackle big hills.
Unfortunately, regular e-bikes are more expensive than their pedal-only peers. Most people have already invested in a traditional bike, so an electric bike is an extra expense.
Thanks to technology, there is a solution to this problem. You don’t have to buy an e-bike; you can turn your existing bike into one with an electric bicycle conversion kit.
There is a plethora of electric bicycle conversion kits from which to choose. On the one hand, having a lot of choices is a positive thing because it means there is likely something to suit everyone’s needs. On the other hand, it can seem intimidating to encounter so many choices.
Luckily, it is possible to choose an e-bike conversion kit that matches your needs. Here are 10 great options.

How Do Electric Bicycle Conversion Kits Work?
There are different parts on an electric bike conversion kit. There is a sensor that senses when you’re pedaling, a motor, a controller that coordinates the activity, and, of course, the battery that powers everything.
You charge the battery by plugging it into an outlet or, in the most modern e-bikes, the battery charges when you ride downhill.
You start the motor by pedaling. The sensor senses the pedaling and passes the signal onto the controller, which will then activate the motor.
The sensor also picks up when you stop pedaling. It sends a signal to the controller, which deactivates the motor.
There may be other parts, such as digital displays, a throttle, and brake gears connected to the kit. These parts vary depending on the design.
What are the Three Types of Electric Bike Conversion Kits?
There are many different designs for e-bike kits. However, these designs get based on three main styles.
- Front-wheel e-bike conversion kits
- Mid-drive e-bike conversion kits
- Rear-wheel e-bike conversion kits
Front-Wheel E-Bike Conversion Kits
A front-wheel conversion kit involves the replacement of the entire front wheel. You need to install a new motorized wheel with built-in controllers and speed sensors.
The kit typically comes without a battery, which you have to source separately. This type of kit is especially suitable for road bikes. One of the biggest advantages is that the installation is easy, especially if your bicycle has a quick-release front wheel.
Mid-Drive E-Bike Conversion Kits
Mid-Drive conversion kits affix to the frame of your bicycle. They sit between the two wheels.
These kits are popular because the extra weight is centered and placed low on the bike, making it more stable and easy to control. Also, because you’re driving your bike from the middle, the power is distributed evenly.
The mid-drive conversion kit comes with a motor that you will attach to your bike’s conversion arm. It will then be able to power your chain system. This design is useful if you want to leverage the power of the motor on all gears, which can make going up hills much easier on the e-bike.
Because they are more complex, mid-drive conversion kits are more expensive than their wheel cousins.
Rear-Wheel E-Bike Conversion Kits
A rear-wheel electric bicycle conversion kit works pretty much like a front-wheel one. That said, they provide more stability than front-wheel conversion kits since they power the e-bike from the back.
The main downside with this type of conversion kit is that it can be cumbersome. All the weight is on the back and not well distributed as it is with the mid-drive conversion kit. As a result, you’re going to have to make sure your bike has a sturdy frame from before you fit this type of conversion kit on it.
Can You Install an Electric Bike Conversion Kit Yourself? What Tools Do You Need?
There are different ways to go about an electric bike conversion kit installation, depending on the specific type you’re installing. There are some things you’re going to need for all installations:
- The electric bike conversion kits
- A crank arm tool
- A bike tool
- An adjustable wrench
- A screwdriver
Wheel E-Bike Conversion Kits
Fortunately, the process for installing front-wheel and rear-wheel e-bike conversion kits is mostly the same.
Start by removing the old wheel. If you’ve ever changed a flat tire on a bicycle, then this should be a breeze. It’s much the same process as you would go through if you were trying to change the inner tube on the wheel.
Next, install the motorized wheel from the conversion kit. Again, this is the same process as changing a flat tire on a bicycle.
Now, you have to install the brake levers on the bike. Disconnect your brake cable from and remove the original brake handles on your bike and install the ones that come with the e-bike conversion kit. You will then connect the brake cable to these new brake handles.
Your conversion kit is likely to come with a throttle and a gauge. These should be installed on the handlebar and secured with screws.
You need to install the sensors and receiver. There are typically two types of sensors on the average e-bike conversion kit. The most important is the pedal sensor, which should be on the crank arm. To install it, you should unscrew the crank arm, install the sensor and secure it with a washer, and then reattach the crank arm. The other sensor is the speed sensor, which will get fitted to the spoke of whichever wheel you are converting. You usually attach this sensor with a zip-tie.
After that, you mount the battery. The battery usually sits on a mounting plate screwed onto the middle frame of your bike. Whichever type of battery you’re working it, installing it is typically as simple as tightening a few screws.
Finally, you will connect the wires to the different controls. Most conversion kits come with color-coded wires, which makes the work much more manageable. You can then zip-tie the cables to the frame of the bike, so it all looks neat and doesn’t get tangled.
Mid-Drive E-Bike Conversion Kits
The process for installing a mid-drive e-bike conversion kit on your bicycle is a little different, though it is also pretty easy if you do it if you have the right tools.
Using your wrench or a specialized crank arm tool, you remove the crank arm and crankshaft.
Next, you install the electric motor, which will go on the crankshaft. The motor comes with screws and washers.
The kit also comes with mounting brackets for the electric motor. You should install these as well, making sure to tighten them. These brackets make sure the engine is secure. This step is especially important if you plan to ride off-road.
Next, you should replace the crank arm and pedals with the ones that came with the conversion kit. It’s about the same process as it is on a regular bike. If you’ve replaced a crank arm before, it should be easy. If not, you might want to watch a few tutorials or get expert help. Make sure the pedals are on the right side (right pedal on the right and left pedal on the left).
You need to reattach the chain to the derailleur that came with the e-bike conversion kit. You do this by unhooking the chain from the old crank arm, and then fitting it onto the new derailleur.
Next, you need to install the battery. This step is as easy. It involves attaching brackets into the bike frame and fastening the battery onto the brackets.
Next, the speed sensor sticks onto your wheel’s spokes.
The cables that connect the different parts of the system should get zip-tied to the frame of the bike. they are well secured and do not get caught on anything during operation.
Next, install the brakes and cables, much like you would do with a wheel conversion kit. The cables are often color-coded so you know which wires connect with which part of the system.
Bicycle conversion kits are a great way to take part in the e-bike trend without having to invest in a fully-electric bicycle. They are cheaper than full e-bikes if you already have a quality bicycle.
If you have do-it-yourself skills and a bike that you already love to ride, then a kit is the obvious choice for you. Even if you do not think you are handy enough, you may find an easy-to-install kit with precise directions that can guide you through the process.
There are different options for electric bicycle conversion kits, so you can easily find the one that best fits your needs. Whether you are a casual commuter or a cycling enthusiast, you can find an e-bike kit that will work with your cycling style.
