Why Riders Choose the Fat-HS

Every component is there to change what you can climb, how far you can go, and what you can bring with you.

01

Climb Steeper

Mid-drive power works through the bike's gears, so steep climbs and loose access roads feel controlled instead of punishing.

Mid-drive torque
02

Ride Longer

A 48V 15Ah battery paired with efficient mid-drive power delivery keeps you rolling deeper into the route.

Carry More

Built for hunting gear, camping equipment, and whatever your route demands.

Adventure ready

Not All 1000W Motors Ride the Same

A hub motor pushes from the wheel. The Fat-HS mid-drive works through the bike's drivetrain — changing how power, balance, and traction feel on demanding terrain.

Typical Hub Motor
Fat-HS Mid-Drive
Power delivered at the wheel
Power delivered through the drivetrain
Less climbing torque
Gearing multiplies climbing torque
Rear-heavy weight distribution
Balanced, low center of gravity
Less efficient on steep hills
Uses the bike's gears for climbing efficiency
More wheel spin on loose ground
More controlled traction
Higher battery demand under load
More efficient power delivery

The same 1000W feels dramatically different when delivered through a mid-drive motor. More torque. Better balance. Greater control.

One Platform. No Single Kind of Trail.

Hunting

Quiet. Powerful. Go where trucks cannot.

Mountain Trails

Technical climbing. Confident control.

Camping

Pack more. Ride farther. Explore deeper.

Snow & Sand

26×4.0-inch fat tires. A wide contact patch. Maximum traction.

Bafang Mid-Drive Power

The Power Core

Bafang Mid-Drive Power

A mid-drive motor sends power through the bike's gears, giving the Fat-HS mechanical leverage for steep climbs, loose terrain, and loaded rides. Balanced weight, efficient delivery, torque where it matters.

  • 1000W Bafang mid-drive motor
  • Power through the drivetrain
  • Balanced, low center of gravity
  • 9-speed drivetrain
Control Both Ends

Full Suspension

Control Both Ends

Front and rear suspension work together to absorb roots, washboard, and broken ground while helping both tires stay composed.

  • Full suspensions
  • KENDA fat tires
  • Smooths roots, ruts, washboard
  • Composed on broken ground
Power for the Long Way Round

The Battery

Power for the Long Way Round48V 15Ah

The 48V 15Ah battery keeps the Fat-HS rolling on long, mixed-terrain days. Efficient mid-drive delivery means less wasted energy under load — more of the battery goes to moving you forward.

  • 48V 15Ah capacity
  • Efficient mid-drive delivery
  • 5 levels of pedal assist
  • 2-year battery warranty
Four Inches of Confidence

All-Terrain Contact

Four Inches of Confidence26×4.0-inch fat tires

A wide tire footprint adds grip and flotation across snow, sand, mud, gravel, and rough forest roads. Where a standard tire sinks or slips, the Fat-HS floats and bites.

  • 26×4.0-inch fat tires
  • Grip and flotation on soft ground
  • Snow, sand, mud, gravel
  • Confident, controlled cornering

Questions? Answered.

Can I get a different model as my second bike?

This event applies to the Fat-HS — both bikes in the offer are the same model. For mixed-model orders, reach out to our team or visit a Fifield dealer.

Is the Fat-HS good for hunting?

Yes — that's one of its core use cases. A mid-drive motor is quieter than a hub motor under load, the fat tires keep traction on soft forest ground, and the full suspension keeps the ride composed when you're carrying gear.

What's the difference between the Fat-HS, Specter-S 3.0, and Rogue Wave Pro?

All three share the 1000W mid-drive power class and full suspension. Fat-HS is the most accessible price point with a 48V 15Ah battery. Specter-S 3.0 steps up to the flagship G510 motor and bigger battery. Rogue Wave Pro carries the largest battery (48V 20Ah) for the longest range and more premium design.

Can I test ride before buying?

Yes — you are welcome to fifield local dealers and our brand showroom is in Hingham,MA where you can test ride before you commit.

What does the warranty cover?

Every Fifield e-bike includes a 2-year warranty on the frame, battery, and motor, excluding normal wear-and-tear items like tires, brake pads, and chains.

How long does shipping take?

Orders ship free within the continental U.S. Reach out to our team for current lead times.

Customer Reviews

Overall rating: 5.0 / 5 from 4 reviews.

Very robust. The FAT-HS / Hunter X8's full suspension enables you to ride offroad more comfortably. It's got strong power and torque with the throttle, or with pedal assist. The 4.5" tires do a great job at soaking up bumps.

Bought this for my campsite, so I can off-road ride. Very impressed with its ability to go over just about any terrain; rocky, mud, grass, dirt, hilly, etc.. The wide tires make for a fun, stable ride! It's a beast.

This was my first experience with an electric bike. I Absolutely love it. The ability to customize the seat height is perfect for petite people who often struggle with standard equipment. I found the control instructions easy to understand and easy to use all functions.

I did an extensive bit of research before I bought this bike and I am extremely pleased. I think this is where quality and affordability are at its max for an E bike. Plenty fast and powerful. I'm having a blast with this bike.
