Build Your Own Ebike: Fat Tire Electric Bike Conversion Kit with Battery

Electric ebikes have skyrocketed in popularity in the last few years, but the concept has existed since the 1800s. In case you were wondering, that’s older than the commercial jet airliner, which made its maiden flight in 1954.

Unfortunately, many have been left out of the ebike craze because some quality ebikes can cost thousands of dollars. However, it is possible to transform an existing bike into an ebike. In fact, you can do it from your own home if you like!

In this article, we will be going over what a fat tire electric bike conversion kit with battery is and how you could own one for just a couple hundred dollars today.

Best Fat Tire Electric Bike Conversion Kits

You may wonder what a fat tire electric bike conversion kit with battery is and how they even work. Well, these kits are an inexpensive way of owning your ebike. Common components that you’ll find within a conversion kit include: 


  • A hub motor: This part is what provides propulsion to your ebike’s wheels. It generates the necessary power to assist you or offer full electric propulsion.
  • Battery pack: This component works in tandem with the hub motor. It’s responsible for storing and supplying the electrical energy to power the motor. Although many kits often do not include an ebike battery, it must be purchased separately.
  • Controller: The controller is the middleman between the hub motor and the battery pack. It manages the flow of power traveling from the battery to the motor. As a result, it regulates the level of assistance provided to the rider.
  • Throttle or pedal-assist system: The throttle is what you would use to control the amount of electrical assistance your ebike’s motor provides. In contrast, a pedal-assist system is much more automatic. It detects your pedaling and provides assistance based on your chosen level.

You would take the parts that a conversion kit provides and install them on your chosen bike. This transforms a regular bicycle into a powerful and versatile ebike. Let’s look at some conversion kits that make this all possible.

Rear Wheel LCD Display E-Bike Conversion Kit

The Rear Wheel LCD Display E-Bike Conversion Kit is perhaps the most complete kit we have listed here today. Aside from necessary components such as a 1000W 48V brushless hub motor and a battery connection cable, this kit also has a rear wheel.

This isn’t just a wheel frame we are talking about but an entire wheel with a tire! Another powerful addition is the high-quality LCD display that you can use to display and keep an eye on vital information such as:

  • Battery power level
  • Time
  • Speed
  • Mileage
  • And the pedal-assist system

To direct how much power flows into your ebike, you can use the two-speed throttle handlebar grips that come with the kit. Note that this conversion kit has no ebike battery, which you should purchase separately.

Electric Bike 36V/250W DC Motor Brush Conversion Kit

Like its predecessor on this list, the Electric Bike 36V DC Motor Brush Conversion Kit does not have its own ebike battery. However, you get a highly efficient motor and kit for a low price. Also included is a Freewheel and Freewheel adapter.

A freewheel is a crucial ebike part that keeps your pedals stationary even when the bike is in motion. This prevents painful blows to your shins and legs from ever occurring.

The freewheel adapter is necessary to convert the rear wheel of your ride and make it freewheel compatible. One last inclusion in this kit that deserves merit is the headlight with battery indicator and horn. These last tools improve your visibility and could even save your life.

Electric Bike Left Drive 450W/36V Conversion Kit

The Electric Bike Left Drive Conversion Kit is for those that want a middle-of-the-road option. While not necessarily the most powerful motor on this list, it certainly is not the weakest. Included with this kit is a 450w motor with its freewheel.

This motor can get you through any city or even more choppy terrain like dirt trails. This kit also includes a customized sprocket to boost the efficiency of said motor further. This is a game changer because a sprocket is crucial in transferring power from the motor to the wheels.

When the motor turns, it engages the sprocket, which drives the chain. While an ebike battery is not included with this kit, other key components that this kit offers include:

  • One chain
  • One motor controller
  • One mounting plate
  • One thumb throttle

Building Your Very Own Best Fat Tire Ebike

As we’ve just seen, electric bike conversion kits offer all the essentials to build your ebike. The one exception is an ebike battery, which you may need to purchase separately.

However, if you manage to do it, it would be hard not to feel a strong sense of accomplishment after building your ebike. Think about a time in your life when you made something with your own hands. Didn’t it feel special every time you used or looked at it? 

This sense of accomplishment could be yours whenever you ride down the street or through a trail.


Let’s get into the basic steps of building your versatile ride. Once done, you’ll have your custom ride that you can be proud of.

1.Choose Your Base Bike: Select a suitable base bicycle for your project. Look for a sturdy and well-constructed frame that can handle the weight and power of an electric conversion. 
Fat tire bikes, known for their stability and all-terrain capabilities, make an excellent foundation for a fat tire ebike conversion.
2.Select the Right Conversion Kit: Investigate and choose a high-quality fat tire electric bike conversion kit that aligns with your requirements. These kits typically include a hub motor, controller, and sometimes a throttle or pedal-assist system. 
Ensure compatibility with your chosen base bike, considering factors like motor power and installation ease.
3.Assemble with Precision: Carefully follow the instructions provided with your conversion kit for assembly. You'll need basic mechanical skills and tools to install the components onto your base bike. 
Pay special attention to proper alignment, secure wiring connections, and accurate motor, battery, and controller positioning.
4.Personalize and Fine-Tune: Assemble the key components and unleash your creativity. Consider adding unique accessories like fenders, lights, or a custom paint job to make your fat tire ebike truly one-of-a-kind. 
To suit your riding preferences, fine-tune the electric system settings, such as pedal-assist levels and throttle responsiveness.
5.Test and Safety Checks: Conduct thorough tests and safety checks before taking your creation for a spin. Ensure the brakes, lights, and all components are functioning correctly. 
Test the electric system's responsiveness and take a short ride to assess the bike's overall performance and stability.
6.Embrace the Ride: With your best fat tire ebike complete, it's time to embrace the ride and explore new horizons. Experience the thrill of cruising over various terrains, whether sandy beaches, snowy trails, or city streets. Your unique creation is a testament to your ingenuity and passion for adventure.

Building your fat tire ebike is an empowering journey that allows you to craft a ride that perfectly suits your preferences and style. As you take on this hands-on project, you'll gain a deeper understanding of how ebikes work and a heightened appreciation for the exhilarating world of electric cycling.

If you’ve got questions, don’t worry; we have answers. In this section, you’ll have your most pressing ebike conversion kit questions answered.

Are Fat Tire Electric Bike Conversion Kits Compatible With Any Bicycle?

While most kits are designed to be versatile, compatibility may vary based on several factors. These factors include frame size, wheel size, and brake type. Choosing a kit that matches your bike's specifications is essential, and consult the manufacturer's guidelines to ensure a proper fit.

How Far Can I Ride on a Single Charge With a Fat Tire Electric Bike Conversion Kit?

The range of an electric bike using a conversion kit depends mainly on your battery capacity. However, other factors affecting your range include terrain, rider weight, and assistance level.

Will Adding a Conversion Kit Affect the Weight and Handling of My Bicycle?
