How We Evaluated Fat Tire E-Bikes
Our team of experienced testers and riders spends many hours and miles riding all sorts of electric bikes, from e-mountain and road to e-commuters and folding. We used most of these fat tire e-bikes on bike paths and in town around our Easton, PA, office—to grab lunch, commute to and from work quickly, pick up beer and groceries, or just for fun.
The thing about fat tires is that they nudge you to go pretty much anywhere and try pretty much anything without fear—which can be both a good and bad thing (one tester jumped the Aventon Sinch over a blazing 6-foot-wide fire pit). We tested most of the bikes here. And for the ones we didn’t, we based their merit on our experience and rigorous research to compare the bikes’ value, parts, and performance to those we have tested.

Another bike that nails the utilitarian trifecta of being fat-tired, folding, and e-assisted, the RadExpand 5 improves on its predecessor, the RadMini 4, by shaving 5 pounds off the bike’s total weight and widening the tires from 3- to 4 inches. The result is a bike that won’t win any classic style awards but serves up a ton of functionality in a powerful but compact and stow-able package.
The bike has a low step-thru frame—it fits riders between about 4-feet-10-inches and 5-feet-10-inches—and offers a 275-pound capacity, which allows you to also haul cargo on the included rear rack. Mechanical disc brakes come standard on all Rad Power bikes, and though they’re not as powerful as hydraulic discs, they get the job done. The bike also comes outfitted with a front light and LED tail light, and a seven-speed MicroShift derailleur that’s easy to operate via the thumb shifter.
Aventon Aventure.2 Fat Tire E-Bike
Pros
- Racks, fenders, lights included
- Powerful disc brakes
Cons
- Heavy
Key Specs
| Power | 750W |
|---|---|
| Weight | 77 lb. |
| Max Assisted Speed | 28 mph |
| Estimated Range | Up to 60 miles |
“Big” is the best descriptor for this larger-than-life Aventure.2 e-bike. Aventon combined big tires and big power to make a bike with the potential for big fun. The cushy 4-inch-wide tires and suspension fork provide extra comfort when riding over broken pavement or fire road and doubletrack-type trails. The Aventure.2’s rear-hub motor delivers 750W of torquey power and pedal assistance up to 28 mph, or 20 mph, via the thumb-operated throttle.
The Aventure.2 rides smoother than the original Aventure, thanks to a new torque sensor that allows more control over acceleration. The bike comes outfitted with fenders, hydraulic disc brakes, integrated LED lights, and the option to add accessories, like a front or rear rack. The downside to all of these features is a hefty in weight.
Pros
- Peppy motor with lots of torque
- Well appointed and trail ready
- Great price and value
Cons
- Lacks tubeless rims
- Non-preload adjust fork
Key Specs
| Power | 750W |
|---|---|
| Weight | 54 lb. |
| Max Assisted Speed | 20 mph |
| Estimated Range | Up to 80 miles |
The Aventon Ramblas is a category-defining hardtail e-MTB that impressed us during trail testing. Its trail-forward components include a 1x12 SRAM Eagle drivetrain that can handle most climbs, powerful four-piston SRAM brakes, a solidly stiff 35mm RockShox fork, a comfy dropper seatpost, and cushy 2.4-inch wide tires. These are unmatched by any other hardtail e-MTB, especially given its price.
The Ramblas has no true competitors for comparatively priced, trail-ready e-MTBs. Every so often a bike comes along that entirely shifts the bicycle market—the Ramblas might do that for mountain biking. And once more bike brands see and ride the Ramblas, I expect several will soon follow Aventon’s lead with sharp-priced, trail-capable hardtail e-MTBs.

The RadRover has been the most popular fat tire electric bike in the U.S., according to import records from China that show Rad imports surpassing other competitors by a significant margin. So think of the RadRover as the Ford Model T of fat tire e-bikes: inexpensive, reliable, and for everyone.
There’s ample power from a 750-watt (W) geared hub motor to help you get the 72-pound bike up to speed, and the hydraulic disc brakes have no problem bringing the bike to a stop. Puncture-resistant 4-inch-wide tires reliably help you get where you’re going. A comfortable saddle, fenders, and integrated lights round out this well-equipped adventure machine.
Pros
- US support and dealers
- Upright positioning
- 20” x 4.0” tires
Cons
- Cable disc brakes

There are a lot of budget-priced e-bikes on Amazon. So, how do you know if you’re getting unrideable junk or a decent bike? Since e-bikes are electric items that require service, we recommend buying bikes from brands that have U.S.-based offices. Troxus has support from its office in Vista, California, and a network of dealers across the U.S. This allows you to procure parts or get warranty service on your e-bike more easily.
Troxus’ Lynx is unique and slightly quirky (in a fun way). It’s a zippy-riding commuter-style e-bike with 20”x4.0” fat tires, a suspension fork, a 750-watt rear hub motor, and a tall BMX-style bar. The Lynx also has a sturdy wood-topped rear rack, lights, fenders, and a comfortable saddle with a handle. The bike’s frame holds the 960Wh integrated downtube battery and a step-through design that makes getting on or off this e-bike easier.
Our biggest issue with this Lynx model is its cable-actuated disc brakes. While easier for many home mechanics to service, cable disc brakes do not offer the level of power or modulation of hydraulic stoppers. However, Troxus also offers the Lynx Plus with hydraulic brakes for an extra $300 via its website and dealer network.
Pros
- Suspension fork smooths out bumps
Cons
- Heavy and difficult to carry while folded
Key Specs
| Power | 500W |
|---|---|
| Weight | 66 lb |
| Max Assisted Speed | 20 mph (20 mph, throttle) |
| Estimated Range | Up to 40 miles |
With a suspension fork and 4-inch-wide tires, Aventon’s Sinch broadens the types of terrain on which you can ride your folding e-bike. A 500W motor gives you the power and torque needed to climb hills, and a throttle gives you the option of not pedaling at all.
Its off-road stature means the Sinch isn’t as portable as most folding electric bikes; it weighs 66 pounds and takes up nearly 17 cubic feet while folded. That means the Sinch is better for people buying a folding e-bike to take up minimal space in an RV or apartment, not those needing to carry their bike regularly. The Sinch is also available in a step-through model.
Pros
- 1000W peak output motor
- Long range battery available
- Built-in rear rack
Cons
- Heavy given its size
Key Specs
| Power | 500W |
|---|---|
| Weight | 64 lb. |
| Max Assisted Speed | 20 mph |
| Estimated Range | up t0 45 miles |
The Lectric XP 3.0 is a striking e-folder with 3-inch-wide tires on 20-inch wheels and an industrial-styled forged-aluminum frame. The battery is integrated into the frame, which powers a 500-watt hub motor with 55Nm of torque. This gives the XP 3.0 up a claimed 45 miles of range.
A seven-speed drivetrain provides gearing for varied terrain, and there’s a throttle to let you zip along pedal-free. It includes a 50mm travel suspension fork, as well as a large LCD screen. The bike ships as a Class 2 e-bike but can be upgraded to a Class 3, increasing its max speed to 28mph from 20mph.
Pros
- Easy to stow in a trunk or RV
- Front and rear suspension
Cons
- Potential quality issues with battery and brakes
Key Specs
| Power | 350W |
|---|---|
| Weight | 56 lb. |
| Max Assisted Speed | 18.6 mph |
Swagtron’s EB-8 Outlaw isn’t just a mash-up between the genres of fat bike and e-bike—it also sits at the center of a Venn diagram that includes “folding bike.” This compact seven-speed bike boasts 20-inch wheels with 4-inch tires and front and rear suspension for navigating both pavement and gravel.
It can go up to 21 miles at full power, tops out at 18.6 mph, and stows down into a small trunk space—making it ideal for commuting or bringing on road trips (if you can hoist its 56-pound weight.) Just note that with e-bike cost savings, you’re sacrificing battery quality—in this case, riders have reported quality control issues with the batteries and mechanical disc brakes.
Pros
- Comes with LED lights
- Solid accessory packages
Cons
- Only one frame size
Key Specs
| Power | 250W |
|---|---|
| Weight | 65 lb |
| Max Assisted Speed | 20 mph (28mph, Performance Sport model) |
| Estimated Range | Performance Sport: Up to 70 miles (400Wh), up to 80 miles (500Wh); Performance: up to 75 miles (400Wh), up to 85 miles (500Wh) |
Out of all the utility e-bikes we’ve ridden, Benno’s RemiDemi looks and feels the most like you're zipping through town on a Vespa or some other stylish motorized scooter. The bike is as cute as it is functional with a colorful and compact frame built on a shorter-than usual 1,130mm wheelbase, and the Performance Sport model has a throttle that revs it up to 28mph and makes you feel like you’re really flying.
In terms of functionality, the RemiDemi’s Bosch Performance mid-drive motor has a generous estimated range of 80 miles on a single charge—and the bike has a nine-speed Shimano drivetrain, hydraulic disc brakes, and excellent list of accessory options, both included (fenders, integrated LED lights, a rear rack) and available at an additional cost (front racks, pannier bags, kids’ seats, and more). It’s the ideal city commuter, though its tough 4.25-inch Duro Tires are capable on rough terrain as well.
Bicycling Experts Answer Your Most Commonly Asked Questions About Electric Bikes
What are some of the biggest differences between a bike with a 250W motor and a 500W or 750W motor? How much power do you really need?
This is a more complicated question than it seems. Our expert panel is mixed on what motor wattage can mean for your ride. Test editor Dan Chabonov says it depends on the terrain and how many gears the bike has. “You could get away with a 250W motor somewhere flat, though a fat tire e-bike will likely be heavy enough that it will still struggle to get going,” he says. “For a fat e-bike, 400W to 500W should ensure a good user experience—and if you live on a hill, get the most powerful motor you can afford.”
Senior test editor Matt Phillips has a different and more complicated take. “The biggest differences are probably marketing,” he says. “Most e-bike motors have two wattage ratings: a constant rating (how much power the motor can consume for an essentially infinite time period without burning up) and a peak. Many brands will use a motor’s peak rating in their marketing because it’s bigger and therefore sexier than the constant rating.
Two things about the peak rating, though: One, the motor can only hit that for a very short period of time before damage occurs, so it’s not really relevant to day-to-day use; and two, watts are a unit of consumption, which means that an inefficient motor will use more watts than an efficient motor, even if—for practical purposes—they produced the same assistance. So, a 350W motor sounds more powerful than a 250W motor, but it might also mean that it’s not as good. As far as how much you need, get the most powerful motor and biggest battery you can find or afford. You can always turn down the assist on a more powerful bike.”
Deputy editor Tara Seplavy has a similarly nuanced take about wattage numbers. “Not all wattage is marketed equally—there is a difference between ‘peak’ wattage and ‘sustained’ wattage,” she says. So a 750W motor from brand X might be more powerful than a 750W motor from brand Y. For example, the Aventon Aventure’s 750W motor can sustain 750 watts, but its peak is 1,040. As for your wattage needs, that depends on your intended usage of the bike, she says. “If you are a heavier-weight rider, if the bike is heavier, if you live in a hilly area, or if you intend to ride the bike off paved surfaces, a higher wattage system is important,” she says. “Wattage needs are also different for hub-motor vs. mid-motor bikes. A mid-drive bike with 250W motor can feel significantly more powerful than a hub-drive bike with a 750W motor.”
Where and when can I legally ride an e-bike that goes over 20mph?
This can vary by state, city, and even type of road surface. For example, in Durango, Colorado, where Phillips lives, “it is or was legal to ride a Class 3 e-bike on the roads, but it was prohibited on the bike paths and multi-use trails,” he says.
You’ll want to check into your local restrictions, which are constantly being updated to reflect changes in bikes and rider usage. But first you should understand the e-bike classification system. E-bikes are grouped into a system that categorizes them as Class 1, or pedal-assist bikes only, with no throttle, with a maximum assisted speed of 20 mph; Class 2, or bikes that have a maximum assisted speed of 20 mph, but are throttle-assisted; and Class 3, or bikes that are pedal-assist only, with no throttle, and a maximum assisted speed of 28 mph.
Many areas base their restrictions on those classifications—and though there are some national CPSC guidelines, according to Phillips, it’s tough to make any blanket statements about legality. QuietKat’s website has this useful summary of state-by-state regulations.
Can you get an e-bike repaired at a regular bike shop?
On this, Chabanov, Phillips, and Seplavy agree that it depends on the shop. “Some places don’t have a repair stand that can sustain the weight of some e-bikes, but most should be able to do normal bike repairs, like gear adjustments and flat fixes,” says Chabonov.
Seplavy elaborates: “These bikes are heavy and can be difficult to work on for even very experienced mechanics. If you’re not confident doing your own repairs, call around to find a shop that will repair e-bikes before you find yourself stuck needing something fixed. Some shops will not or cannot work on them due to insurance liability issues, while others might only work on the mechanical parts (or even require you to remove the battery before dropping it off). Repairs on e-bikes (especially hub-motor e-bikes) will generally cost more as the bikes are more difficult to work on. The shops aren’t being snobby or dismissive, the bikes really do take much longer to fix than non-assist bikes.”
Phillips adds that it’s best to check in with the motor manufacturer (for example, Bosch) or the bike brand to see what shops are certified to work on their equipment.
How many miles can you usually get on a single battery charge? And where can I charge my e-bike?
“This will vary greatly based on your weight, the bike’s weight, the level of assist you use, how hilly your route is, and how big your battery is—but bikes should be capable of somewhere between 20 and 45 miles,” Chabanov says.
Seplavy adds one thing, “Using that throttle is a lot of fun, but use it wisely if you intend to ride long distances as it will quickly drain your battery.”
As far as where to charge it, Phillips says: “All e-bikes that I know have chargers that plug into a standard household outlet. I don’t know of any commercial e-bike charging stations similar to the Tesla Supercharger network. Not that e-bikes need that because they can be charged easily and fairly quickly off household current.”
And if the bike’s battery comes off, it’s even easier to take it inside with you and charge at any outlet.
