EUNORAU DEFENDER Electric Bike

Full-Suspension Comfort for Roads and Trails That Refuse to Stay Smooth

City potholes, gravel paths, and uneven trails can quickly make a rigid commuter bike uncomfortable. The EUNORAU DEFENDER Electric Bike combines front-and-rear suspension, wide tires, hydraulic brakes, and steady rear-motor assistance for riders who want more control when the pavement becomes rough.

It is built for commuting, recreational riding, maintained trails, and light off-road exploration without requiring the extreme power or added weight of a dual-motor electric bike.

Reliable Rear-Wheel Power

The DEFENDER uses a 500W rear hub motor with up to 60Nm of torque. It provides helpful acceleration and support on moderate inclines while keeping the bike’s standard on-road speed limited to 20 mph.

Five pedal-assist levels allow you to choose how much support the motor provides. A thumb throttle gives you access to motor power without continuous pedaling, while the Shimano 7-speed drivetrain helps you adjust your effort across hills and flat terrain.

Full Suspension for Better Control

A 100mm-travel front suspension fork absorbs impacts from rocks, bumps, and damaged pavement. The rear air shock helps reduce the movement transferred through the frame, allowing the rear wheel to respond more effectively to changing surfaces.

This full-suspension setup improves comfort and helps reduce fatigue during longer rides. The 27.5-by-3-inch tires add cushioning, traction, and stability without the extra bulk of traditional four-inch fat tires.

Confident Braking on Changing Terrain

Front and rear hydraulic disc brakes use 180mm rotors to provide responsive stopping control. Motor-cutoff switches interrupt electric assistance when the brake levers are engaged, helping create more predictable braking.

A 40-lux front light and rear taillight improve visibility during early-morning, evening, and lower-light rides.

Standard Battery with Optional Expansion

The DEFENDER includes a removable 48V 15Ah lithium-ion battery. The battery can be unlocked and charged indoors instead of requiring the entire bike to be placed beside an outlet.

The frame also supports compatible optional second-battery configurations. With two batteries installed, the manufacturer estimates a range of up to 80 miles under favorable conditions. Secondary batteries are sold separately, and compatibility depends on the selected frame size and battery capacity.

Two Frame Sizes for a Better Fit

The DEFENDER is available with a 17-inch or 19-inch frame. This gives riders more flexibility when choosing a comfortable reach and stand-over height. The recommended rider-height range is approximately 5 feet 3 inches to 6 feet 4 inches, but individual fit preferences will vary.
