Everything You Need to Know About Fat Tire Electric Bike Kits (2021)

We’re not going to sugarcoat it – assembling your own electric bike requires considerable research and knowing your way around hardware.

There are two DIY ways of assembling an electric bike in Flint:

  1. You could do all of the research for the parts yourself, this means cross-referencing all parts for compatibility, testing dozens of times to make sure the parts go well together
  2. Or, you could buy a fat tire electric bike kit that comes with all essentials included. You just have to put everything together like a jigsaw puzzle.

Unless you have your own machining tools and have a degree in engineering (or considerable experience in the garage), we don’t recommend option 1. Instead, it’s more convenient to purchase a fat tire electric bike kit and just follow the instructions.

Pro tip: If you want, you can swap out less powerful parts for more powerful variants. But you could run into incompatibility issues and may need to do some tinkering.

If you feel comfortable getting your hands dirty and don’t mind a weekend spent tinkering with an old bike, then buying a fat tire electric bike kit is definitely going to be worth your time. After all, nothing feels more rewarding and fulfilling than constructing your own ebike.

Let’s get down to brass tacks.

What is an Electric Bike Kit?

Fat tire electric bike kits, also known as ebike conversion kits, come with electric motors that can convert a regular bicycle into an electric bike. In most cases, a fat tire electric bike kit consists of the following four key components:

  1. Hub motor or mid-drive motor – This is the part that allows your bike to propel forward through electricity.
  2. Battery – Without a good battery, your motor will stop functioning.
  3. Pedelec – This essential kit helps you read your cycling cadence when you’re pedaling and sends a signal to your motor to assist you.
  4. Fat Tires – No fat tire electric bike kit is complete without thick tires for improved traction. This is important if you want to go off-roading.

Advanced kits can also include more components, including a controller that regulates the current going into all parts of the bike, a speedometer, and components for a throttle.

In general, the components found in an electric bike are the same as you’ll find on any premium eBike out there. The only difference, of course, is that you’ll be left doing the assembly yourself.

What are the Benefits of Buying a Fat Tire Electric Bike Kit?

Electric bike kits cater to a wide spectrum of audiences. In most cases, they’re an affordable means of upgrading your bicycle.

Here are a few reasons why so many bicyclists prefer fat tire electric bike kits:

  • Pedal Assistance: With pedal assist, your motor powers up as soon as you start pedaling. You can set how much motor power you want to assist you when pedaling. The biggest advantage of pedal assist is that it lets your motor take over when you’ve exhausted all your energy. The only caveat is that the motor depends on your battery. Without a good battery, your motor simply won’t work.
  • Climbing Hills: This is a big one: cycling up steep hills can be a monumental challenge, particularly when you’ve already cycled several miles. A fat tire electric bike kit lets you tackle steeper hills effortlessly. Moreover, these kits are especially useful if you have longer trips with multiple hills to ride.
  • Commuting: Eco-conscious motorists are now switching to electric bikes in droves. A fat tire electric bike kit easily lets you commute to and from work. Most conversion kits are very eco-friendly, so you’re doing the environment a big favor.
  • Off-Roading: It’s not easy taking a regular bicycle on an off-roading trip because you need good traction (with thicker tires) and power in case you’re out of breath. Fat tire electric bike kits are a great way of turning your old beat-up two-wheeler into an offroading electric bike. With the right kit, you can easily take your bike off-roading.
  • Customization: eBike customization offers more than just an aesthetic upgrade, you can customize everything from raw horsepower to adding an entire roster of features (including wheel style, GPS, paint color, etc.). There are many aftermarket upgrades you can apply and an unlimited number of combinations.

With all that said, we will be the first to admit that electric bike kits aren’t a safe bet for everyone.

For example, if you don’t have basic mechanic skills, it would be hard to put together fat tire electric bike kits. Unless you’re prepared to swap out the crank on your old bicycle, we don’t recommend going down the DIY path.

If you’re not ready to convert your bicycle into an electric bike, we recommend buying an off-the-shelf electric bike from premium manufacturers like Ancheer and Swagtron.

However, if you’ve got experience changing the cranks on your bicycle and changing the wheels, then a fat tire electric bike kit might be right up your alley.

Types of Electric Bike Conversion Kits You Should Know About

In your research, you will hear many terms, including  ‘mid drive’, ‘geared hub’, and  ‘brushless motors’. If these terms are flying over your head, continue reading to learn more about them.

  • Hub Drive: This motor can power either the front or rear of your bike. The motor is directly installed in the wheel’s hub, hence the term ‘ hub drive’. When choosing hub drive motors, you have two choices:
  • Front-wheel: They are perfect for flat terrains and acceleration.
  • Rear-wheel: If you want strong torque and superior performance on mountainous terrains, then you should go with a rear-wheel drive.
  • Mid Drive: These motors offer several advantages over hub drive motors, including being lightweight, discreet, and offering unadulterated power. Fat tire electric bike kits with mid drives are ideal for traversing difficult hills with relative ease. They reach extremely high speeds, which is why it’s recommended to have good brakes that can stop the bike in seconds.
  • Geared Hub: This all-important part consists of several rotating gears that can provide power to the motor while getting the most out of the battery. Geared motors can be configured to give you extremely high torque performance, but you can’t achieve high speeds with them.
  • Brushless Hub: This motor does not come with gears but makes use of a rotor and stator instead. They use your bike’s battery to power up magnets and start spinning the wheel. In general, brushless hub motors can reach extremely high speeds and are much quieter (because they don’t have gears!).

In addition, here are a few terms that you should be familiar with when researching fat tire electric bike kits.

  • Wattage: This indicates how much power your electric bike is capable of putting out. More wattage equals more speed.
  • Voltage: This term refers to the amount of electrical potential your battery holds. Standard electric bike batteries are 36V and 48V.
  • Amperage: It helps to think of the amperage as a fuel tank. Higher amperage usually translates into more power.
  • Pedelec: This term is used when an electric bike requires the rider to pedal before the motor can start running. The term is shorthand for “Pedal Electric”.

Together, the watt, voltage, and amperage propel your bike forward, giving you more control over your ride and speed.
