Electrek dubbed the Defender-S a “rocket ship” — and they weren’t exaggerating. Driven by twin 750W Bafang hub motors (1500W peak output / 160Nm combined torque) delivering relentless all-wheel drive traction, this full-suspension powerhouse transforms steep backcountry climbs, loose scree, and deep snow into a confident cruise. Equipped with dual Samsung battery capability for 80+ miles of remote range, 180mm hydraulic disc brakes, and full air/coil suspension, the Defender-S is engineered for riders who refuse to turn around when the trail ends.

WHO'S THIS FOR

  • Backcountry Hunters & Anglers: Haul heavy packs, hunting gear, or trailers deep into wilderness management areas where single-motor bikes spin out.
  • Off-Road Explorers & Ranch Managers: Tackle rugged acreage, rocky switchbacks, and unmaintained trails with the plush comfort of full front and rear suspension.
  • All-Weather Year-Round Commuters: Conquer sand, mud, gravel, and snow without loss of steering traction thanks to true all-wheel drive motor pull.

FROM PROBLEM TO SOLUTION

The Steep Climb Dilemma

Single-motor hub e-bikes frequently bog down, overheat, or spin their rear wheel on loose 25%+ mountain grades. The Defender-S Solution: Twin 750W Bafang motors deliver 160Nm of instant AWD torque — the front wheel pulls while the rear pushes, gripping loose rock and clawing up steep inclines effortlessly.

Trail Fatigue & Body Impact

Heavy rigid or hardtail fat tire bikes transfer brutal vibration and shock to your lower back, knees, and wrists on technical descents. The Defender-S Solution: An inverted RST 75mm front suspension fork paired with an EXA Form 165mm rear air shock completely isolates the cockpit and chassis from trail chatter.

Range Anxiety in Remote Wilderness

Running out of battery 20 miles out in remote backcountry terrain is dangerous. The Defender-S Solution: A primary 48V 15Ah Samsung battery with dual-battery expansion capability provides up to 32Ah total capacity for 80+ miles of continuous exploration.

REAL-WORLD SCENARIOS

Colorado High-Country Elk Hunt

You’re packing 120 lbs of field gear up a 2,500-foot elevation ascent over wet mud and loose shale switchbacks. Engaging dual-motor AWD delivers instant traction with zero tire spin, smoothly delivering you and your gear to base camp without breaking a sweat.

Texas Hill Country Ranch Patrol

Navigating 400 acres of caliche ranch roads, dry creek beds, and rocky fence lines. The full-suspension chassis cushions every ledge and rut while the 48V Samsung power plant runs all day on a single charge.

ASSEMBLY & COMPATIBLE ACCESSORIES

Assembly & Setup Guide: The Defender-S arrives safely boxed with partial assembly required for transit protection (handlebar attachment, front wheel quick-release installation, pedals, and headlight mounting). A comprehensive multi-tool kit and setup guide are included.

DEFENDER-S

1500W ALL-WHEEL DRIVE TRACTION

Twin 750W Bafang Hub Motors Delivering 160Nm of Instant Climbing Torque

Single-motor e-bikes lose momentum and spin out on steep, loose terrain. The Defender-S features dual independent 750W Bafang geared hub motors that power both wheels simultaneously. A handlebar-mounted rocker switch lets you toggle on-the-fly between single-motor rear drive for maximum battery range on flat pavement, and 1500W AWD muscle when conquering 30%+ grades, mud, deep snow, or loose mountain scree.

DEFENDER-S

TRUE FULL-SUSPENSION TRAIL CONTROL

Inverted RST Guide Hydraulic Fork Paired with Kindshock EXA Rear Air Shock

Rigid fat bikes punish your wrists and spine over rocky descents. Built on a four-bar linkage suspension chassis, the Defender-S pairs an inverted RST Guide 75mm hydraulic front fork with a tunable Kindshock EXA Form 165mm rear air shock. The suspension isolates the cockpit from trail chatter and heavy drop-offs, keeping both 26x4.0" Kenda fat tires glued to the earth for maximum steering authority.

DEFENDER-S

EXPEDITION DUAL-BATTERY RANGE

Dual Samsung Battery System Providing Up to 32Ah for 80+ Miles of Exploration

Never cut a backcountry expedition short due to battery anxiety. Powered by a primary 48V 15Ah Samsung lithium-ion battery and engineered with a dedicated dual-battery expansion port, the Defender-S scales up to 32Ah total capacity. With smart load-balancing between packs, you get 80+ miles of pedal-assist range to reach remote wilderness camps and haul out heavy game.

SPECIFICATIONS & COMPLIANCE

Know Before You Buy: Specs, Laws & Assembly

E-Bike Class Flexibility & CPSC Compliance

Classification, Off-Road Compliance & Safety Guidelines:

  • ⚖️ Dual-Motor Power Disclaimer: The Eunorau Defender-S is equipped with dual 750W motors (1500W total peak output). In full AWD mode, this vehicle exceeds standard 750W single-motor Class 1–3 parameters and is intended for off-road trails, private property, backcountry hunting grounds, and BLM/commercial land where higher-wattage e-bikes are permitted.
  • 📜 Public Road & Greenway Usage: Always check your state, county, and municipal regulations before operating on public streets and multi-use paved greenways. When operating in public access zones, switch to single-motor mode and adhere to posted 20 mph speed limits.
  • ⛑️ Mandatory Safety Protection: Due to the high torque and off-road speeds of dual 750W motors, Pathfinder Pedal strongly recommends wearing a CPSC or ASTM-certified helmet, eye protection, and durable riding gloves at all times.

Real-World Range & Battery Safety

Dual-Battery Architecture & Winter Storage Protocols:

  • 🔋 Samsung 21700 Lithium-Ion Chemistry: The primary downtube pack utilizes high-drain Samsung cells configured for high-torque dual-motor discharge without premature voltage sag.
  • Dual-Battery Equalizer Switch: When equipped with the secondary battery, the integrated smart isolator draws power evenly across both packs to prevent thermal imbalance and maximize overall cell longevity.
  • 🔌 Smart Dual Charging: Both batteries feature individual key locks and integrated charge ports, allowing you to charge on the bike or unlock each pack for indoor charging at standard 110V outlets.
  • ❄️ Cold-Weather Storage: Never charge lithium-ion batteries in freezing temperatures. For winter hunting camps, bring battery packs inside a heated cabin or vehicle to warm above 32°F (0°C) before plugging into the smart charger.
