Product Description

EUNORAU DEFENDER-S – Dual-Motor All-Terrain Fat-Tire E-Bike

The EUNORAU DEFENDER-S is a powerful, full-suspension electric fat bike designed for rugged trails, adventure riding, and off-road exploration. With dual 750 W hub motors, fat 26″ × 4.0″ tires, and quality suspension both front and rear, this model delivers serious traction, comfort, and climbing power — ideal for hunters, weekend adventurers, and thrill-seekers alike.

Dual 750 W Motors for Maximum Traction

The DEFENDER-S’s front and rear 48 V 750 W hub motors combine for a total of 1,500 W of power. This AWD setup delivers strong torque (80 N·m each) for climbing steep trails, powering through loose terrain, or cruising with serious acceleration.

Long-Range Dual Battery System

Standard with a 48 V 15 Ah battery and compatible with an optional 15 Ah or 17 Ah second pack, the DEFENDER-S can extend its range to **80+ miles**. The removable battery design makes charging flexible and convenient for long rides.

Full Suspension for Comfort & Control

The bike’s frame features a **75 mm travel RST front fork** and a 165 mm rear shock, offering excellent compliance over rough terrain. The rear EXA suspension smooths out big bumps, while the front absorbs trail chatter — keeping your ride stable and controlled.

Responsive Braking & Gearing

Hydraulic disc brakes with 180 mm rotors at both ends ensure confident and reliable stopping power, even when riding loaded or at top speeds. Paired with a 9-speed Shimano drivetrain, you'll have smooth, precise shifting whether climbing or descending.

Intuitive Display & Throttle

The LCD display (C3 / BC182) shows your speed, battery level, and pedal-assist mode. A thumb throttle gives you instant power when you need it, while a motor-switch enables choosing front, rear, or both motors to match your riding needs.

Durable & Utility-Ready Design

Aluminum 6061 full-suspension frame — Built to handle off-road stress.
Fat 26″ × 4.0″ Kenda tires — Excellent traction across sand, snow, or rugged terrain.
Full protective bash guard — Safeguards the chainring from rough impacts.
Integrated LED headlight & rear taillight — Enhance visibility day or night.
Pedal-assist levels: 0–5 — Choose power to match your pace.
