Full-Suspension Trail Utility with Optional Dual-Battery Range

The EUNORAU DEFENDER is the current 500W rear-drive full-suspension platform for riders who want a lighter-output alternative to the Defender S 2.0 while keeping trail-ready tires, hydraulic braking, two frame sizes, and dual-battery capability.

Why the DEFENDER Stands Out

  • 500W rear hub motor: Current 48V system with 60 Nm of torque.
  • 48V 15Ah primary battery: Removable main battery with compatible optional second battery.
  • Up to 80 miles with dual batteries: EUNORAU's current headline extended-range figure requires a compatible dual-battery configuration.
  • Full suspension: 100mm front suspension plus EXA KS/A5 rear shock.
  • 27.5" × 3.0" tires: A wider trail-oriented footprint without the full bulk of a 4-inch fat tire.
  • Hydraulic disc brakes: 180mm front and rear rotors with motor cut-off.
  • Two frame sizes: 17" and 19", both available in Army Green and Safari.
  • UL certified: Manufacturer-listed current certification.

Key Specifications

  • Motor: 48V 500W rear hub
  • Torque: 60 Nm
  • Battery: 48V 15Ah primary; optional 15Ah/17Ah second battery depending on frame compatibility
  • Published Extended Range: Up to 80 miles with dual batteries
  • Maximum Speed: 20 MPH speed-limited configuration
  • Payload Capacity: 300 lbs / 136 kg
  • Recommended Rider Height: Approximately 5'3"–6'4"
  • Tires: 27.5" × 3.0"
  • Brakes: Hydraulic disc, 180mm front and rear
  • Drivetrain: Shimano 7-speed
  • Display: BC182 with EUNORAU app support
  • Frame: 6061 aluminum alloy

Second-Battery Compatibility

The optional 17Ah second battery is not compatible with the 17" DEFENDER. On the 19" frame, EUNORAU notes that using the 17Ah second battery requires locking out the rear shock. Confirm your intended battery configuration before ordering.

Current Configurations

17" Army Green, 17" Safari, 19" Army Green, and 19" Safari.

Best For

Choose the DEFENDER if you want full suspension, wider trail tires, easier handling than a dual-motor fat bike, and the option to extend range with a second battery.

Great Value for a Dual Battery

Dual batteries deliver steady power for longer routes. Assembly was straightforward and the hardware feels premium.

The Defender handles rugged terrain with confidence. Solid build, responsive brakes, and a stable ride even with a full load.

Ready for Daily Deliveries

Perfect for daily commutes and short deliveries. The cargo rack is practical and the motor/torque handle hills with ease.

Smooth throttle response and predictable braking. Feels planted on gravel and city streets alike.
