With a max speed of 20 mph / 32 kph, using the pedal assist or the throttle. This makes the 604 Boar a class 2 rated electric bike, which might be restricted in some places.

The Boar is made from 6061 aluminum alloy and weighs in a relatively light 58 lbs / 26 kg. An LCD color display is located in the handlebars’ center and offers speed, distance, battery level, and more.
Stopping power is handled by Tektro Auriga hydraulic disc brakes. Comfort is only from the 26 x 4.5-inch tires as it comes with solid front forks. If you want to go hunting, there are pre-drilled bosses for a front rack, and it comes in a matte Kryptek camouflage to blend into the wilderness.
Biktrix Juggernaut Ultra 1000
The Biktrix Juggernaut Ultra 1000 is a versatile fat tire electric bike. This electric bike is totally customizable when you buy it, with a variety of tires, batteries, forks, and brakes which means the price can vary depending on your choices. You even have the options for a rack, fenders, and street tires rather than fat tires.
This is a powerful bike at 1000-watts with a torque sensor that provides 1500 watts of peak power with an LCD display showing a watts bar, speed, and voltage. The battery is removable with a key to bring it into charge.
The Juggernaut is well constructed, and the SRAM NX is a great gear set. The chainstay length is long, but given the range of tires it supports, it needs to be. Axels are quick release with custom spacing 135mm front and 190mm rear, which will make it hard to find stock wheels.
The Juggernaut 1000 is in the middle of the Bitrix range. They have the cheaper Juggernaut HD and Juggernaut Classic or the more expensive ultra FS and Ultra Eagle to cover everyone’s needs and price range.
Rad Power Bikes RadRover 5
The Rad Power Bikes RadRover 5, as the name suggests, is the 5th generation full-sized, high-step, fat tire electric bike. Rad Power is a company that was at the origins of the fat tire uprising.
This is a stable and capable bike on all-terrain, especially on soft trails, sand, and snow on its 4-inch wide knobby tires with puncture protection. It features a curved top-tube, short, sturdy stem, and mid-rise handlebar for comfort.
Power is delivered from a 750-watt Bafang motor, this throttle on-demand class 2 certified bike has a range of 25- 45 miles / 72 km and a top speed of 20 mph / 32 kph. The RadRover 5 has adjustable suspension forks with preload adjust for heavy loads and lockout for smooth terrain.

The LCD display gives you more precision with a 9 bar battery infographic compared to other affordable displays of 4 or 5. The screen is a little on the small side but does have an in-depth menu and backlighting, which is sufficient and less prone to damage.
One minor let down is rear light power. It’s not wired to the main battery pack using disposable AAA batteries. You’ll forget to switch them off and with an electric bike without a light!
iGO Electric Core Extreme 2.0
The iGO Electric Core Extreme 2.0 is another affordable fat tire electric bike that is packed with features. It comes with durable plastic fenders, a sturdy rear rack, and integrated lights.

What is a Fat Tire Electric Bike?
An fat tire electric bike sometimes called a fat e-bike or fat tire e-bike is an off road electric bike with what looks like oversized comical tires.
Typically 3.8-inches or larger, up to 5-inches, these e-bikes are designed to allow riding on soft, unstable terrain, such as sand, snow, mud and bogs.
What are Fat Electric Bikes For?
Fat Bikes were initially designed to ride or roll across sand, snow, mud, wet roots, rocks, and other terrains. This is commonly known as ‘Floatation.’
This is no longer the case as the vast majority of fat bikes are ridden on the regular trails that you ride any mountain bike on. As they make great bikes for exploring, backpacking, or riding singletrack at any place, and will guide you through extraordinary experiences.
You can ride a fat bike pretty much anywhere as they offer a fantastic amount of grip with their tractor like traction tires. They are an alternative to suspension bikes and should not be as a way to soak up the bumps.
Why Ride a Fat Electric Bike?
These wide tires allow the rider to tackle near impossible terrains such as deep sand and snow while giving the feeling of riding on air.
Floaty Fat Tires
How floaty do you want your electric fat bike to ride? The principle choice here is 4-inch tires or bigger. Not many riders are well served by tires bigger than 4-inches.
Unless you are buying the e-bike for a specific experience and are mainly riding on deep sand or snow, don’t get into the temptation of the fattest tires possible. They’ll be extremely sluggish and bouncy and will quickly turn into becoming not much fun and reduce your range.
As you can see from our top picks, most 4-inch tire fat e-bikes offer the complete fat experience with hardly any drawbacks or compromise.
