If you’re a thrill-seeker looking for the ultimate electric mountain bike experience, look no further! With power output peaking at 2,000W, you’ll experience astonishing acceleration while remaining in control due to the all-wheel-drive set up. This e-bike can go up to 35mph (56 km/h) and give you that adrenaline rush that’s so addictive! All that power does consume battery life quickly, so we’d recommend getting the optional 2nd battery for extended adventures.

A well-matched front & rear suspension is welcomed on such a high-performance machine, helping devour rough terrain with ease. You can take it on recreational MTB trail rides, enduro single tracks or even hunting thanks to its camouflage and game hauling capabilities. And with wide 4.0” fat tires, you can also cruise on sandy beaches, float over snow and ride on virtually any loose terrain.

The Defender-S comes in medium (17”) and large (19”), suiting riders from 5’3 to 6’4. An optional 14Ah secondary battery is available for both sizes while the larger 17Ah battery only fits the large 19” frame. It comes in three colors: black, grey, and forest cobra which is a unique camo design that will surely please wildlife enthusiasts.

Last but not least, Eunorau’s excellent 2-year warranty on all electrical components, including the motor and battery(ies) means you can enjoy this electric bike with peace of mind for many years to come. All-in-all, the Eunorau Defender-S is a beastly machine, with high-quality parts that can withstand its high-performance. If you’re looking an ultra-capable and uncompromised mountain e-bike, you’ve found it!

They also have a motor cut-off switch to disengage the motor while the brakes are applied.


RST Guide 75mm Suspension Fork – Effectively absorbs most jarring bumps and shocks, especially on the rougher terrains you will encounter on this e-bike. Greatly improves comfort and handling while reducing fatigue.


Exa KS582 165mm Rear Suspension Air Shock – The rear-suspension is designed to further cushion rougher terrain, creating a stable feel that allows you to pedal and throttle forward with ease.
