The Hunting E-Bike You Can Climb On in Waders
Here's a problem nobody warns you about.
Most hunting e-bikes have a high top tube you have to swing a leg over. Easy enough in a parking lot in jeans. Now try it at 4:45 a.m. with a 30-pound pack on, bibs and a heavy coat zipped up, on a sloped two-track in the dark. Or in chest waders at the edge of the creek. That leg-over is where people tip bikes, scrape shins, and start the morning annoyed.
The EUNORAU FAT-HD 2.0 (Hunter X7) fixes that first. It's a step-thru frame: the tube dips low, so you step through and sit down instead of swinging over. Then it gives you everything a hunter actually needs once you're on: a 1,000-watt mid-drive, 4-inch fat tires, and a removable battery you can charge anywhere.
Let's walk through what each of those numbers means on the ground.
Why "Mid-Drive" Matters When You're Loaded and Climbing
Cheaper e-bikes put the motor in the rear wheel. That kind of motor has a single gear, so on a steep hill with a pack on, it bogs down.
This one is a Bafang 1,000W mid-drive. It sits at the pedals and drives the chain, so it gets to use all 9 Shimano gears just like your legs do. Downshift before the climb and the motor stays in its sweet spot instead of lugging, the same way a truck pulls a trailer uphill in low gear.
It puts out 160 Nm of torque. Torque is the pulling force that gets you going from a stop and keeps you climbing under weight. The commuter e-bikes on our site make 55 to 65 Nm, so this has roughly two and a half times the pull.
The assist is cadence-based. Once your pedals turn, the motor helps at whichever of the 5 levels you've chosen, without you having to push hard. You can spin lightly and arrive at the stand without sweating through your layers. A thumb throttle moves you with no pedaling at all, and a gear sensor briefly eases the motor as you shift to protect the chain.
A Battery You Can Carry Inside
The 48V 15Ah battery uses Samsung cells and holds about 720 watt-hours, which you can think of as the size of the gas tank. It locks onto the frame and lifts off with a key, so you can charge it in the house, the cabin, or the truck, and keep it warm overnight instead of leaving it in a freezing shed.
The frame is also built to take a second battery (sold separately). With two packs, EUNORAU rates the bike at up to 80 miles. On one pack, you're well covered for typical in-and-out trips to the stand. If you ride long distances, hunt in hard cold, or pull a trailer, the second battery is the upgrade to plan for.
Tires That Float Instead of Sink
Kenda 26" × 4.0" fat tires are about twice the width of a mountain bike tire. More rubber on the ground at lower pressure means they float across sand, mud, snow, and wet leaves instead of cutting in and stalling. An RST suspension fork up front takes the sting out of roots and ruts, and the wide tires cushion the rear.
Stopping and Seeing in the Dark
The hydraulic disc brakes use 180mm rotors front and rear. Hydraulic brakes use fluid instead of a cable, so a light squeeze gives you strong, consistent stopping even when they're wet or your hands are cold. Touch either lever and the motor cuts out immediately.
A front LED headlight and rear light are included, and the Bluetooth color display shows speed, battery, and assist level clearly before sunrise.
Built to Carry, Legal Where Bikes Are
The bike is rated for 375 pounds of total payload, rider and gear combined. It ships as a Class 2 e-bike, assisted up to 20 MPH, the class most states treat like a regular bicycle.
The Honest Part
- "80 miles on one battery?" No. The 80-mile figure is with the optional second battery. One pack gives you meaningfully less, and less again in cold weather or when hauling. If your hunts are long, add the second battery, or look at the FAT-HD 1.0 Pro's bigger 25Ah pack.
- "Does it come with a rack?" No rack or fenders in the box. Plan on adding EUNORAU's rack and fender set for gear. For a whole deer, use a game trailer or quarter it and make two trips, and check any trailer's hitch fits the FAT-HD before buying.
- "Is it silent?" Far quieter than an ATV, but a mid-drive hums under load. Drop to the lowest assist level, or pedal, for the final approach.
- "How heavy is it?" 81.6 pounds. Plan on a hitch rack rated for fat-tire e-bikes.
- "Can I ride it on public land?" Many public tracts marked non-motorized don't allow e-bikes. Private land and leases are where this bike shines.
Is This Your Bike?
The FAT-HD 2.0 fits riders 5'3" to 6'4", with a seat that adjusts from about 31.9" to 38.6" off the ground. Pick it if you want the easiest mount in the Hunter line, a removable battery, 9 gears, and the color display.
If you're 5'7" or taller and would rather have a bigger built-in battery plus a rack and fenders already on the bike, look at the step-over FAT-HD 1.0 Pro (Hunter X7). If you want rear suspension for very rough ground, see the FAT-HS (Hunter X8) two-bike bundle.
What Shows Up at Your Door
A factory-sealed EUNORAU FAT-HD 2.0 in Safari, Army Green, or Mamba, mostly assembled, with the battery, charger, lights, bell, and tool kit. The free gear kit shown above ships with it. EUNORAU's warranty covers the motor, battery, and electronics for 24 months and the frame for 10 years, and our Ride Desk handles any claim for you. Shipping is free to the lower 48, it arrives in about 7–10 business days, and you have 14 days to return it if it isn't right.
Choose your color above and make the walk in the easy part of the day.
FAT-HD 2.0 Questions
Do I need the second battery?
For short trips to the stand and back, one battery is usually enough. If you ride long distances, hunt in freezing weather, or pull a trailer, the second battery is worth it.
Is it good for fishing trips too?
Yes. The step-thru frame is easy to mount in waders, the fat tires handle sandy banks and gravel access roads, and a rear rack (sold separately) carries rods and a tackle box.
Why does Mamba cost more?
It's the camo-pattern finish. The motor, battery, and components are the same across all three colors.
Can it haul a deer?
Yes, with a game trailer or by quartering and making two trips. The 160 Nm mid-drive through 9 gears handles loaded climbs well. Confirm a trailer's hitch fits the FAT-HD before you buy it.

Quick answers
The questions riders ask us most, answered up front. Want to talk it through? The Ride Desk is glad to help by chat or at (855) 970-3574.
Do I need the second battery?
For short trips to the stand and back, one battery is usually enough. If you ride long distances, hunt in freezing weather, or pull a trailer, the second battery is worth it.
Is it good for fishing trips too?
Yes. The step-thru frame is easy to mount in waders, the fat tires handle sandy banks and gravel access roads, and a rear rack (sold separately) carries rods and a tackle box.
Why does Mamba cost more?
It's the camo-pattern finish. The motor, battery, and components are the same across all three colors.
Can it haul a deer?
Yes, with a game trailer or by quartering and making two trips. The 160 Nm mid-drive through 9 gears handles loaded climbs well. Confirm a trailer's hitch fits the FAT-HD before you buy it.
Why buy from Vortex instead of somewhere else?
It's the same factory-sealed EUNORAU bike with the full manufacturer warranty. What you get on top: the free gear kit shown above, our price match (find it lower at another authorized dealer and we'll match it), and the Ride Desk. If anything goes wrong, you send us a message and a short video and we handle the warranty claim with EUNORAU for you, so you're never stuck in a support queue alone.
When will it arrive?
Usually in 7–10 days. Shipping is free to the lower 48 by FedEx or UPS, and a signature is required so your bike is never left on the porch. You'll get tracking by email as soon as it ships.
How much assembly is there?
The bike arrives mostly assembled. You'll typically attach the handlebar, front wheel, pedals, and seat, and the manufacturer's step-by-step video walks you through it. Get stuck? Send the Ride Desk a photo and we'll talk you through it.
Will it fit me, and can I handle it?
Check the specs above and the size chart in the photos. If you're near the edge of the height range, between frame sizes, or unsure about the weight, send us your height and inseam. We'll tell you straight, even if the answer is a different bike.
How far will it really go?
The range in the specs is the manufacturer's test number, usually measured with a light rider in a low assist level on flat ground. Heavier riders, hills, wind, cold, and throttle use all shorten it. Tell us your weight and your usual route, and we'll give you a realistic estimate.
Is it legal where I ride?
The class rating and top speed are in the specs below. In most states, an e-bike ridden within its Class 1, 2, or 3 limits doesn't need a license, registration, or insurance, but trail and town rules vary, so check yours. Any higher-speed modes are for private property only.
How should I charge and store it?
Use the included charger, charge on a hard surface away from anything flammable, and unplug once it's full. For longer storage, keep the battery partly charged in a cool, dry place and top it up now and then. Your owner's manual has the exact guidance for your model.
Can I pay over time?
Yes. Choose Shop Pay Installments at checkout: buy today and pay in 4 or more payments starting at 0% APR. Checking your eligibility won't affect your credit score. Rates from 0–36% APR. Payment options through Shop Pay Installments are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders.
