Eunorau FAT-HD 2.0 / Hunter X7 — 1000W Mid-Drive Fat Tire Electric Mountain Bike

160 Nm Through 9 Gears. 375 lb Payload. Quiet Enough to Ride to the Stand.

Most hunting eBikes use hub motors. Hub motors are loud, inefficient on hills, and have one gear ratio that either works or doesn’t. The FAT-HD 2.0 is not most hunting eBikes. It runs a Bafang 1000W mid-drive motor with 160 Nm of torque through a Shimano 9-speed drivetrain — the same motor platform that powers our best-selling Flash 1000W and SPECTER-ST 2.0. The motor is whisper-quiet, torque-sensing, and drives through the gears so it multiplies force on steep terrain instead of stalling on it.

Pair that with 26″ × 4.0″ Kenda fat tires that roll over roots, mud, snow, sand, and logging roads without flinching, an RST suspension fork that absorbs trail punishment, and a 375 lb payload capacity that carries you, your gear, your tree stand, and your cooler — and you have a purpose-built machine for getting deep into the bush and back out again. Quietly

The FAT-HD 2.0 supports dual batteries. Start with the included 15Ah Samsung pack. Add an optional second battery when you need more range — Eunorau rates the dual setup at up to 80 miles. The frame has the mounting points built in from day one.

Why a Mid-Drive Changes Hunting

Hunters care about three things on an eBike: quiet, torque, and range. The FAT-HD 2.0 delivers all three because of the mid-drive architecture:

• Whisper-quiet operation — Mid-drive motors run at the pedals, not the wheel hub. The Bafang 1000W mid-drive produces a low hum that disappears into ambient forest noise. Hub motors whine. On a November morning walking distance from a deer stand, that difference matters.
• 160 Nm through 9 gears — The motor torque multiplies through the Shimano 9-speed cassette. In first gear on a steep logging road, the effective force at the rear wheel is massive. Hub motors have one gear ratio — if the hill is too steep, they stall. The FAT-HD 2.0 downshifts and climbs. We have seen the same Bafang motor platform on the Flash 1000W climb sustained 12% grades fully loaded.
• Efficient range — Because the motor uses the gears, it operates at peak efficiency across varied terrain. The same 15Ah battery lasts longer on a mid-drive than on a hub motor covering the same route with the same hills. Add the optional second battery and you have all-day range deep in the bush.

The torque sensor completes it. The motor responds to how hard you pedal, not just whether the cranks are spinning. Light pressure on a flat trail gives gentle, silent assist. Hard pressure into a grade gives maximum power. No sudden motor surges that spook game. No on/off jolts. Just smooth, proportional, quiet power.

Key Features

• Bafang 1000W Mid-Drive Motor (M615/G320) — 160 Nm — The same proven Bafang platform used across the Eunorau lineup. 1,500W+ peak output. Drives through the Shimano 9-speed cassette for mechanical advantage on every grade. Torque sensor provides proportional, natural power delivery. Whisper-quiet for hunting.
• 48V / 15Ah Samsung Battery — Dual Battery Design — The included 15Ah pack integrates into the downtube and is removable for indoor charging. The frame has built-in mounting for an optional second battery (15Ah) — bringing total capacity to 30Ah and range up to 80 miles. Buy the second battery when you need it. The frame is ready now.
• Shimano 9-Speed Drivetrain — 11–32T cassette with 42T Eunorau chainring and chain guard. 9 gears gives the mid-drive motor the mechanical range it needs to stay efficient from steep climbs to fast flats. Push-button shifter. A clear step above the 7-speed systems on competing hunting eBikes.
• Kenda Krusade Sport 26″ × 4.0″ Fat Tires — 4-inch-wide tires float over soft ground that would swallow standard tires. Snow, sand, mud, loose gravel, wet leaves, root-covered trails — fat tires find grip where skinny tires sink. The Kenda Krusade Sport tread pattern is optimised for off-road traction with reasonable rolling resistance on hardpack.
• RST Suspension Fork — Absorbs trail impacts, roots, rocks, and washboard logging roads. Combined with the fat tires, the front suspension smooths out terrain that would rattle your teeth on a rigid frame. This is a hardtail design — no rear suspension — which keeps weight and maintenance lower for a purpose-built trail machine.
• 375 lb Payload Capacity — Rider + gear + tree stand + cooler + whatever else you need in the bush. One of the highest payloads in any mid-drive fat tire eBike under $3,500. Heavier riders (250+ lbs) still have real headroom for cargo.
• Eunorau 180mm Hydraulic Disc Brakes — Front and rear with motor cutoff switch. The brake sensor kills motor power the instant you squeeze the lever — critical on a 1000W mid-drive descending a steep, loose trail with cargo. Consistent, fade-free stopping in wet and cold conditions.
• Eunorau BC182 Bluetooth Colour Display — Bright colour screen readable in direct sunlight. Shows speed, battery level, PAS mode, trip data, and odometer. Bluetooth connectivity for pairing with the Eunorau app. Clean cockpit layout.
• 28 mph Top Speed — Class 3 capable. 5 pedal assist levels + thumb throttle for on-demand power. PAS 1–2 for quiet, efficient cruising on the approach. PAS 4–5 for getting out of the bush fast when you need to.
• LED Headlight & Taillight — Battery-powered integrated lights for dawn and dusk rides. No separate batteries to manage.
• 42T Chainring with Guard — The chain guard protects the drivetrain from brush, branches, and trail debris. Essential for off-road riding where exposed chainrings catch everything.
• Two Frame Sizes — 17″ and 19″ frames to fit riders 5’3″ to 6’4″. Adjustable seat height from 31.9″ to 38.6″.
• Three Camo & Tactical Colours — Safari (desert camo), Army Green, and Mamba (dark camo). Every colour option is designed to blend into the bush, not stand out on a bike path.

What You Should Know (Honest Take)

• This is a hardtail — no rear suspension. The RST fork and fat tires absorb a lot, but aggressive rocky trail riding will transmit impacts through the rear. For full suspension with the same Bafang mid-drive, look at the SPECTER-S 3.0 / Hunter X9 ($4,099, inverted fork + DNM rear shock). The FAT-HD 2.0’s hardtail design keeps weight lower and eliminates rear shock maintenance — a trade-off, not a flaw.
• ~80 lbs is heavy. You are not carrying this over a fallen tree. The motor makes the weight disappear on trails, but if your hunting route requires portaging, factor this in.
• 15Ah is modest for a 1000W mid-drive. On aggressive PAS levels with hills, expect 30–50 km from the single battery. The dual battery design fixes this — but the second battery is an extra purchase. Budget for it if your rides regularly exceed 40 km.
• You need to shift gears. This is a mid-drive. It works through the 9-speed cassette. Downshift before hills, upshift on flats, shift under light pedal pressure. If you do not want to shift, do not buy a mid-drive — buy a hub motor fat tire instead. If you are willing to learn (one afternoon), the reward is a ride that no hub motor can match on hills and varied terrain.
