Are you looking for an incredible off-road riding beast? Check out the 2021 Defender-S from Eunorau (pronounced U-Nor-O). The Defender-S is a high-end electric mountain bike featuring premium components throughout and some truly innovative ebike technology. It has been designed for the most rugged outdoor riding conditions, with an aircraft-grade 6061 aluminum alloy frame with full suspension, Dual 750W motors, and a long-range battery with second (dual) battery upgrade options, 17" and 19" frame sizes. With a top speed of up to 30 mph, the Defender-S is simply amazing!
Electric Bike Report is an independent and authoritative reviewer of electric bikes, and it's good to see what they say and watch their videos before making this important decision.
It's worth reading the full review, but to sum up their thoughts on the Defender-S, check out their handy Pros and Cons chart.
If you need an electric mountain bike with incredible hill-climbing and towing capabilities, the Defender-S is for you. This model features dual 750W motors.
The heavy-duty full-suspension Defender-S frame is handcrafted from 6061 aluminum alloy, giving the bike incredible strength. It is offered in 17" and 19" frame sizes, so even riders as short as 5'-5" can enjoy riding the Defender-S. The frame is offered in stunning matte black and gorgeous grey finishes.
The suspension components on the Defender-S include the RST Guide suspension fork, which offers 75mm of travel and mechanical lockouts; and the DNM A0-42RC rear absorber, which feature a dark hard-anodized AL-7075 ∅10 mm ( 0.39”) damper shaft, adjustments for rebound, lockout and high pressure, and delivers up to 190mm of travel. Cables are threaded through the frame for a clean design. The battery is integrated into the downtube portion of the frame, with the option for a second battery added on top of the downtube.
The Defender-S has 5 levels of pedal assist, allowing you to finely adjust how much power the motor puts out. It also features a thumb throttle, which allows for riding without pedaling (very stealthy). The Defender-S also features a 9-speed Shimano Alivio derailleur, providing smooth, reliable and fast shifting action, the elimination of unwanted chain movement and an end to ghost shifting.
The 48V/15Ah battery on the Defender-S is located within the downtube, providing an added level of stealth and aerodynamics to the frame. This battery, which is packed with Samsung cells, can be upgraded to 48V/17Ah. And if you really want to extend the range of your ride, there is an option to buy a second battery with 48V/14Ah or 48V/17Ah specs, which mounts on top of the downtube. The controller adjusts the draw from each battery automatically based on voltage and demand. The range these batteries are capable of achieving will vary based on a number of significant factors, including terrain, load, and demand. Please use our Ebike Range Calculator to estimate your expected range per charge.
The Defender-S is a very capable fat tire electric hunting bike, designed especially for natural trails and rugged off-road terrain. You will appreciate the highly responsive speed sensor, that will make slow technical riding feel natural and intuitive. This electric mountain bike is sure to be a favorite of hunters, allowing you to travel great distances to follow game, monitor cameras, and visit remote watering spots. The Kenda 26” x 4” fat tires were designed for use with bikes and feature dense 30 TPI casings, wire beads and K-Shield protection.
Kenda's first line of defense since 1995: a layer of light, flexible rubber containing aramid and ceramic particles inside the tire, under the tread area only. This has been designed to prevent punctures and increase tire life.
These tires will provide excellent traction and stability on uneven and gravely surfaces, and can be ridden on snow and sand. For a wider footprint, you can deflate the tires down to 5 psi, or pump them up to 30 psi when you ride on paved surfaces and want a more responsive feel and performance.
When it comes to stopping with authority, the Defender-S does not disappoint. It features a hydraulic brake system with 180mm stainless steel rotors front and rear, and automatic brake/motor cutoff sensors, so you will never risk motor acceleration during braking.
Electric bikes are an excellent form of transportation, even a highly specialized ebike like the Defender-S. They can be ridden in bike lanes and other areas where cars are prohibited; they have zero emissions and are therefore a greener, ecologically-friendly alternative to cars.
