Eunorau Fat HS / Hunter X8 — 1000W Bafang Mid-Drive Off-Road eBike

Eunorau Fat HS / Hunter X8 — Bafang 1000W Mid-Drive, Full Suspension, Built for the Bush

The Fat HS — also marketed as the Hunter X8 — is Eunorau’s full-suspension answer to the hunters, anglers, and off-road riders who needed a real climbing eBike. Not a heavy hub-drive doing its best on a logging road. A Bafang BBSHD 1000W mid-drive, peaking over 1,500W, throwing 160 Nm of torque through a Shimano/Sunrace 9-speed cassette — the same gear-multiplying principle a motorcycle uses to climb. Drop a gear, hold throttle, and the bike walks up grades that would stall a hub motor.

Full suspension matters more on a 1000W bike than on a 500W commuter. The RST Guide 75mm fork at the front and the KS-388RL 48mm rear shock let the bike track over roots, rocks, and packed-snow ruts without losing traction or beating up the rider. Kenda Krusade Sport 26″ × 4.0″ fat tyres float over mud, sand, snow, and loose gravel. Hydraulic disc brakes with 180mm rotors and motor cutoff handle the stopping load on a fully loaded descent. 48V 15Ah Samsung-cell battery, removable, dual-battery ready — Eunorau rates the dual configuration up to 80 miles / 129 km.

Key Features

• Bafang M615 BBSHD Mid-Drive — 1000W Nominal / Peak Over 1,500W — 160 Nm Torque — One of the most field-proven high-power mid-drives in the eBike world. Drives through the gears, so torque multiplies on a downshift. The signature reason a 1000W mid-drive feels different from a 1000W hub motor on real terrain. Wattage explained →
• Shimano Altus / Sunrace RDM91 9-Speed Drivetrain — 11–34T Cassette — 42T 7075 CNC Chainring — 170mm Forged Alloy Crank — Wide-range 9-speed gearing for genuine climbing low gears and useable cruising highs. The 7075-aluminium chainring is harder than standard 6061 chainrings and survives the chain forces of a 160 Nm mid-drive better than a thinner stamped ring.
• 48V 15Ah Samsung-Cell Removable Battery — ~720 Wh — Dual-Battery Ready — Samsung cells are premium lithium-ion. The battery removes with a key for indoor charging and security. Adding a matched second 15Ah pack roughly doubles capacity to ~1,440 Wh and roughly doubles range — Eunorau rates the dual configuration up to 80 miles. Confirm the current second-battery option and pricing by phone.
• RST Guide 75mm Front Fork + KS-388RL 48mm Rear Shock — Full Suspension — True full suspension at this price point. The 75mm front fork takes the edge off square-edge impacts on the trail; the 48mm rear shock keeps the rear tyre in contact with the ground over rapid undulations — the difference between traction and a fishtail on a wet root crossing.
• Kenda Krusade Sport 26″ × 4.0″ Fat Tyres — Black Alloy Rims — A genuinely off-road fat tyre with an aggressive lug pattern, not a beach cruiser tyre. Floats over loose surfaces (snow, sand, mud) and bites on packed dirt. The 4.0″ width adds a large air cushion that doubles as passive suspension on rough surfaces.
• Hydraulic Disc Brakes — 180mm Rotors — Motor Cutoff Levers — Strong, consistent stopping power that doesn’t fade when the rim gets wet or muddy. Motor cutoff fires the instant a brake lever is squeezed — mandatory on a thumb-throttle bike making 160 Nm.
• Cadence-Sensing Assist + Thumb Throttle — PAS assist is triggered by pedal rotation across multiple assist levels — consistent and predictable on rough terrain rather than proportional to rider effort. The thumb throttle gives instant power-on-demand for moments when you need a torque burst without spinning the cranks — rolling out of a slow technical section, for example. PAS vs throttle →
• CDC6 LCD Display with Waterproof Connectors — Backlit display showing speed, battery state, distance, PAS level. Push mode for walking the bike up technical sections. Waterproof connectors protect the wiring harness from trail spray and rain — not a casual feature on a bike that will see real weather.
• 6061 Aluminium Alloy Frame — Full Suspension — Two Sizes (17″ / 19″) — Aluminium means no rust risk through winter storage in a damp garage. Two frame sizes for a more accurate fit across the 5′3″–6′4″ rider range than a single-size bike can offer.
• Selle Royal Saddle — Nylon Platform Pedals with Reflectors — Selle Royal is a name-brand saddle maker, not a generic vinyl pad — comfortable on multi-hour rides. The platform pedals accept any flat-soled boot, including hunting boots and steel-toe work boots.
• UL Certified — Eunorau states the Fat HS carries a UL certification. The specific UL standard (UL 2849 full-system vs UL 2271 battery-only) is not published on the Canadian product page; if a specific standard matters for your building or insurance, call us before ordering.

Warranty

The Fat HS is covered by a layered warranty: a 1-month Zeus complimentary limited warranty (claim coordination), the Eunorau manufacturer warranty (2 years on the core system), and optional paid Zeus extended-protection plans (1, 2, 3, or 5 years). Standard wear items — tyres, brake pads, chains (a mid-drive consumable, see Honest Take), grips, and saddles — and damage from misuse, improper maintenance, or unauthorised modification are not covered. See our warranty page for full terms, or call 1-866-938-7580 to confirm current Eunorau coverage on the Fat HS before purchase.

What You Should Know Before Buying (Honest Take)

• This bike is off-road / private property only in Canada. 1000W nominal puts it outside the federal PAB definition at any setting. You cannot legally ride it on public roads, bike lanes, or shared-use paths in any province. If you need a road-legal eBike, look at the Eunorau Meta 26, the FAT AWD 3.0 (PAB-compliant at the factory setting), or any of our 500W Zeus Approved commuters.
• Cadence sensor, not torque sensor. Eunorau’s published spec is “cadence-sensing assist.” On a high-power off-road bike this is the more common choice and gives predictable power delivery on rough terrain — but it is not proportional to your effort the way a torque sensor is. If you want a torque-sensing PAS feel, the Eunorau FAT AWD 3.0 is the torque-sensor pick in the lineup.
• Mid-drives wear chains and cassettes faster. The motor power runs through the same chain you pedal through. On a 160 Nm BBSHD that means 2–4x faster chain stretch than on a hub-drive of similar power. Plan to replace the chain at least once a season under heavy hunting use, and the cassette every 2–3 chains. This is normal for the platform — not a defect.
• 77.1 lbs is a real number. Loading into a truck bed solo with hunting gear strapped on requires a ramp or two people. Off-road carrying a downed bike up a slope requires planning.
• 300 lb payload ceiling. The sibling Hunter X7 (FAT-HD 2.0) is rated to 375 lbs. If you regularly carry a heavy hunting load plus rider weight that approaches the 300 lb ceiling, the X7 is the safer pick.
• Headlight lumen rating is not published by Eunorau. The headlight is rated for 6–60V input on the bike’s power but the lumen output is not stated. For deep-bush use after sunset, plan for an aftermarket high-lumen handlebar light as backup.
• IP weather rating is not published. Eunorau states the CDC6 display has “waterproof connectors” but does not publish an IP rating for the full system. Treat the bike as splash-resistant, not submersible — don’t ford a creek deep enough to immerse the motor housing.
• UL standard is not specified. Eunorau states “UL certified” without naming UL 2849 (full-system) vs UL 2271 (battery-only). If your building or insurer requires a specific standard on file, call us before ordering.

None of this is hidden in marketing. The Fat HS is a serious off-road platform that does exactly what it says — and we’d rather you understand the trade-offs before you buy than discover them after.

Will It Fit You? — Sizing & Fit

The Fat HS comes in two frame sizes — 17″ and 19″ — for a more accurate fit across the recommended rider height range of 5′3″ to 6′4″ than a single-frame bike can offer.

Who Is the Eunorau Fat HS / Hunter X8 For?

• Hunters and anglers who need real bush-road climbing. The Bafang BBSHD plus 9-speed cassette outclimbs every hub-drive in this price bracket. If you ride into a stand or a fishing hole that involves a real grade, this is the platform. Best hunting eBikes Canada →
• Off-road and OHV-trail riders. Full suspension plus 4.0″ aggressive-lug fat tyres on a 160 Nm mid-drive is a genuine off-road platform — not a road bike with knobs.
