Front hub motors & Rear hub motors

If you're looking to convert your bike into an e-Bike, you may be wondering if it's better to do a front-wheel or rear-wheel conversion kit. Both have their pros and cons, but which one is right for you? In this blog post, we will discuss the differences between front-wheel and rear-wheel conversion kits, and help you decide which one is best for you!

What are a front-wheel e-bike conversion kit and a rear-wheel e-bike conversion kit? 

A front wheel e-bike conversion kit is a kit that allows you to convert your existing bike into an e-bike by adding an electric motor to the front-wheel. A rear-wheel e-bike conversion kit does the same thing , but adds the electric motor to the rear-wheel instead. Both kits have their own pros and cons that we will discuss below.

The difference between front and rear hub motors

Weight Distribution

During the ride, you definitely want the weight of your e-bike to be as evenly distributed as possible from front to back. You don't want to put all your weight in one place. Typically the battery pack is located in the middle or rear of the e-bike, which means the front hub motor helps distribute the weight forward, making the e-bike's weight distribution even. With a rear-mounted battery (or, a battery mounted on the seat tube), putting the engine on the front-wheel makes the bike look more stable. Not only when cycling, but also when walking. The rear-wheel and spokes are under a lot of stress—your weight, pedaling force, motor power, motor weight, and even the size of the motor make building a wheel more challenging than a traditional bicycle hub. E-bikes with rear hub motors are notorious for breaking spokes too often. In this segment, front-wheel drive has better weight distribution compared to rear-wheel drive.


Due to weight distribution issues, the front hub motor is safer to operate than the rear hub motor. why is that? If all your weight is concentrated on the back of the bike frame, you could accidentally "pop the wheel" during acceleration, which could lead to a dangerous accident. Or, of course, some riders may actually prefer that the rear hub motor has easy access to the wheel, especially if they want to perform tricks or stunts.


Some riders want their e-bikes to look like regular bikes. Front hub motors stand out on commuter bikes; however, rear motors can be mistaken for regular bikes. The rear motor is less noticeable because the brake disc plate can cover it. It might also deter thieves interested in stealing e-bikes.


When moving, front-wheel drive solves the weight distribution problem; but it introduces a new problem: traction control. Since the front wheel of an e-bike is very light, the traction force of the front hub motor is less than that of the rear hub motor.

The higher the voltage, the smaller the wheel, and the more likely the front hub motor will "peel" during acceleration. The 36V motor on the 26-inch wheels usually maintains enough traction, while the front hub motor and 48V motor of any wheel size are likely to experience front tire slip. The rear wheel of the bike carries most of your weight, which is why the rear hub motor has more traction than the front hub motor. Almost all motors run on 48V or higher.

Rear-wheel drive bikes have a lot more traction than front-wheel drive. This is especially important for those who use electric mountain bikes, as they are more likely to go off-road when the ground is less firm and therefore need a better grip.

The pros and cons of  front-wheel vs rear-wheel conversion kits

When it comes to converting your bike into an e-bike, you have two main options: a front-wheel conversion kit or a rear-wheel conversion kit. Both kits have their pros and cons, so it's important to know which one is right for you before making a purchase.

Front wheel conversion kits are typically less expensive than rear-wheel kits, and they're also easier to install. However, front-wheel kits can make your bike less stable, and they can also put more strain on your hands and wrists.

Rear-wheel conversion kits are more expensive than front wheel kits, but they offer some advantages. First, they make your bike more stable. Second, they distribute the weight of the motor more evenly, which can make your ride more comfortable. Finally, rear-wheel kits tend to be more powerful than front-wheel kits, so if you're looking for a little extra power on your e-bike, a rear-wheel kit is a way to go.

No matter which conversion kit you choose, make sure to do your research and buy from a reputable company. With a little bit of effort, you can turn your bike into an e-bike that will make your commute more fun and convenient. 

How to choose the right conversion kit for you 

There are a few things you'll need to consider before choosing a conversion kit, such as: 

-How much money are you willing to spend on the conversion? 

Rear wheel kits tend to be more expensive. If you're on a budget, a front wheel kit may be a better option. 

-What is the terrain like where you'll be riding? 

If you'll be riding on hilly or mountainous terrain, a rear-wheel conversion will give you more power going up hills. If you plan on mostly riding on flat surfaces, a front-wheel conversion will suffice. 

-How much weight are you willing to carry? 

If you don't mind carrying a little extra weight, a rear-wheel conversion will add more stability to your ride. 

-How much time are you willing to spend on the installation? 

Rear-wheel conversions can take longer to install. If you're short on time, go with a front-wheel kit. 

-Which type of bike do you have? 

If you have a mountain bike with suspension, a rear-wheel conversion may be more difficult to install. 

-Do you want pedal-assist or throttle only? 

A front-wheel conversion will give you more control over how much power is going into the motor. If you want a throttle-only option, go with a rear-wheel kit.  

-How far do you plan on riding? 

If you're planning on doing long-distance rides, a rear-wheel conversion will give you more power and range. 

-Do you need to worry about pedaling through water? 

If you live in an area with lots of rain or snow, a front-wheel conversion may be a better option because it won't get as wet. 

Take all of these factors into consideration before making your decision on which conversion kit to buy. Whichever option you choose, you'll be sure to enjoy the extra power an electric motor will give you on your rides!

Installation tips for front-wheel and rear-wheel conversion kits 

Now that you know the basics of front wheel and rear wheel conversion kits, it's time to learn about installation. Here are a few tips to help you get started:

-Start by removing the existing wheels from your bike. This will make room for the new motorized wheels.

-If you're installing a rear-wheel kit, you'll also need to remove the chain and cassette from the rear-wheel.

-Next, install the new motorized wheels according to the instructions that came with your kit.

-If you're installing a rear-wheel kit, you'll now need to reattach the chain and cassette.

-Finally, test out your new e-Bike to make sure everything is working properly. Enjoy!

Converting your bike into an e-Bike is a great way to get around town without having to deal with traffic or parking. With a little bit of know-how, you can easily install a front-wheel or rear-wheel conversion kit on your own. Just follow the tips above and you'll be riding your new e-Bike in no time!
