Is Fat Tire E-Bike Maintenance Necessary?

Fat tire electric bikes have become widely popular with e-bike enthusiasts for a number of reasons. They're environmentally friendly, they're great for commuting, and they're a lot of fun to ride!

One common question people have about fat tire electric bikes is: do they need maintenance? The answer is, yes. Like any other bike, they too need to be properly maintained in order to stay in good condition. 

But don't worry, it's not as much work as you might think. With just a bunch of basic maintenance tips, you can keep your fat tire e-bike running like new. 

Why is Fat Tire E-Bike Maintenance Necessary?

Fat tire e-bikes are the perfect mix of thrill and fun. They offer strength, stability, capability, and speed, all while being an eco-friendly option. These bikes have wide, rugged, and anti-slip tires that can handle sand, snow, mud, and more. They're also great for riding on rough roads, steep trails, jagged hills, or uneven rocky paths. 

And, because they're so versatile, fat tire e-bikes are also great for people who want to use their bike for multiple purposes, like commuting and recreation. If you're looking for a bike that can do it all and can take on any terrain, a fat tire bike is the perfect choice, as it can provide great traction on any kind of challenging surface without compromising on speed or performance. 

Since fat tire e-bikes are built to endure difficult riding conditions and defeat the most formidable of terrains, they require regular maintenance to stay in good shape. As a matter of fact, these bikes need to be maintained and serviced more frequently than their thin tire counterparts.

Cleaning is Crucial for Fat E-Bike Maintenance!

When it comes to maintenance, some rules apply to all e-bikes regardless of type or class. This includes a series of basic steps for maintenance along with things to look out for before setting off on another adventure. Starting with the basics, the simplest maintenance you can do for your fat tire e-bike is to clean it regularly.

If you're someone whose bike looks like it just came out of a dirt track, you should expect drops in the efficiency and quality of your ride. Washing your bike cleans off the excess mud and dirt that's accumulated on it, allowing its parts to function as intended without having to account for additional friction. 

However, while doing so, make sure your battery and electronics aren't exposed to water. Likewise, if you have used your fat tire e-bike in wet conditions, make sure to dry it off as soon as possible. This will prevent rust and keep your bike in good condition. 

How to Maintain Your Fat Tire Electric Bike?

While regular cleaning helps improve the overall condition of your fat tire e-bike, certain parts require special care. 

Here are some instructions that you can follow to make sure every major component of your fat tire e-bike is in top shape. Following these simple tips will help to keep your bike in great condition for years to come! 


Make sure to clean and lubricate your chain regularly. This is just like with a regular bike – if the chain gets gunky, it won't work as well!

Since fat tire e-bikes are designed to be ridden on rough terrains like snow, sand, and mud, you need to keep the chain clean and lubed at ALL TIMES. This will help to keep it safe from rusting and prolong the overall life of your drivetrain components.

As far as lubrication is concerned, it can practically do wonders for your bike. 

The core idea remains the same i.e to reduce friction. Using a high-quality lubricant as per need ensures that all moving parts of your bike – particularly the chain, derailleur, and sprockets – are free to move as intended.


The disc brake system of fat tire e-bikes is made of pads and rotors, which tend to wear out after excessive use. If you notice that your brake pads or rotors are damaged, we advise that you get them replaced as soon as possible.

Some fat tire e-bikes, like the Engwe Engine Pro, are equipped with hydraulic brakes, which may require you to remove air from them in a process known as bleeding. Bleeding is needed when you notice a significant decrease in your braking capability.

If you have the right tools and equipment, you can look up a tutorial and do it at home. In case you're lacking the tools needed, you can always head to your nearest bike shop as they'll know what to do.


Being the key component of a fat tire e-bike, you need to keep an eye on your tires. The greater width of these tires, which stands at an astonishing 4 inches, allows them to have ample friction within different environments. 

But, unfortunately, the tires on the fat tire e-bikes wear out more quickly than the ones used on other types of bikes. It's because they are designed to withstand rough terrains and also because fat tire e-bikes are much heavier than regular bikes. 

Fat tires get worn out after extended use which makes them lose their grip, decreasing ride stability and safety. So, if you notice that the tread on your tires is getting low, you should get them replaced at the earliest.


There are a few different types of suspension systems (spring, hydraulic, pneumatic), and each needs to be maintained differently. 

For instance, in case of hydraulic suspension systems, you need to maintain their oil level and add more of it if necessary. Likewise, you need to maintain correct air pressure in the pneumatic suspension, and add air if necessary. Since it's a relatively difficult task, we suggest you have a mechanic handle it.

Luckily, there are a few things you can do by yourself, if you want to maintain your e-bike suspension. It includes cleaning and lubricating your seals periodically, and checking your fork stanchions for any damage.


If your fat tire e-bike comes with a removable battery, we recommend that you disconnect it from the bike and clean it, preferably with a damp cloth. You can also use a dry brush to clean your battery. Be sure to get the dirt off of the contacts of the battery as well.

Moreover, you can also switch to a waterproof casing for your e-bike battery to prevent it from getting damaged in the rain.

Regarding how to charge your battery, the instructions are to never overcharge it, as well as to never let it drain below 20%. The best way to prolong the life of your electric bike battery is to charge it after every ride, no matter how short it is.

Additionally, leaving your battery in a fully drained state for a long period can also damage it. This can easily be avoided by regularly using your e-bike, or charging your battery every 3-4 months in case you plan to store your bike away for an entire season.

Battery maintenance is of utmost importance as your battery is the single costliest component of your fat tire electric bike… and you might want it to last as long as possible!

Once-Over Inspection Before Every Ride

Aside from the maintenance steps mentioned above, you should also conduct a brief “once-over” checkup before every ride to see if there's anything that needs a detailed look. Here are some things to look out for:

  • Be sure to take a look at your tires before you venture out. Check whether the air pressure is different from the normal. If so, inflate them to the required PSI. Make sure to never go beyond the limit that was provided by the manufacturer.
  • Check your brakes every time before you ride your bike. Make sure that the cables are connected properly, the levers are working as intended, and the padding is not damaged.
  • Look for chipped, broken or damaged parts as well as for any loose or missing nuts & screws to ensure nothing ends up falling apart at the wrong time.
  • Make sure that your battery is adequately charged in accordance with the distance of your trip. Never use your e-bike when the battery falls below 20% as it can rapidly decrease the service life of your battery. 

Final Words

Fat tire electric bikes are perfect for anyone who wants to explore the great outdoors. They're also great for commuters who want a bike that can handle any type of weather or terrain. 

That being said, riding your fat tire electric bike on rough tracks and off-road areas without proper maintenance can greatly reduce its lifespan (and can eventually lead to the financial strain of repair costs). 

With the basic fat tire e-bike maintenance tips we mentioned above, you can avoid that and can make the most of your rides without compromising on safety!

We hope it was an informative read for you!
