Biktrix Juggernaut Ultra FS: A Beast of an E-Bike

the Biktrix Juggernaut Ultra FS. This full-suspension e-bike is an absolute powerhouse, perfect for those who need a bit more oomph in their ride. Set up with fat tires, this bike is ready for winter, soft, and mushy terrains, and even snow. Fat bikes are popular in the e-bike space for their added weight and resistance, which is nicely balanced by the motor’s power, giving you extra boost and range.

Let’s talk about the battery options. The Juggernaut Ultra FS comes with a top-of-the-line, super high-capacity battery pack: 48V, 21Ah. They use Panasonic cells for reliability. The Reention Dorado battery, though asymmetrical, is high capacity and weighs around 10.5 pounds. Other options are inline with the frame and weigh about nine pounds. The bike is heavy, weighing 72.8 pounds, mostly due to the large inverted suspension and fat tires.

Speaking of tires, you can choose from Juggernaut Pros from Kenda (26 x 4.00), plus-size tires (3-inch width), or smooth Schwalbe Super Moto-X for commuting. Each has its benefits, from floating over soft sand to mountain biking to a quieter, more efficient ride. However, transporting this bike can be tricky due to its long wheelbase and the need for specific racks.

The battery is removable, which is excellent for storing it indoors during extreme temperatures to maintain range and longevity. The aluminum alloy casing is tough, and you can even use the USB charging port for your devices when camping. The bike’s frame geometry, with a slack head tube angle, is designed for stability at high speeds and handling big hits.

The suspension includes a RockShox Monarch air suspension with 100mm of travel in the rear and up to 120mm with the optional Renz suspension fork upgrade. The suspension is beefy, making the bike feel sturdy but slightly tippy at low speeds. The motor, a Bafang M620 Ultra, is a beast with 1,000 to 1,500 watts of power and 160Nm of torque. It measures rear wheel speed, pedal cadence, and pedal torque, making it responsive and natural.

The drivetrain includes a physical shift detection system, which cuts motor power when shifting, protecting the drivetrain. The bike features a thick aluminum alloy bash guard guide, ensuring the chain stays in place even under high torque. With hydraulic disc brakes (180mm rotors) and optional quad-piston brakes for added stopping power, this bike is built to handle its power and weight.

The Juggernaut Ultra FS also boasts some great features for commuting, like a headlight and a rear light, both wired into the bike. The digital display shows all the necessary metrics, and the bike includes a walk mode for easier maneuvering in tight spaces. Priced at $3499 USD, it’s a great value for a bike with so many premium features and customization options.

This bike is powerful, versatile, and fun, making it perfect for off-road adventures or commuting. It’s like riding a little motorcycle, offering a unique and exhilarating experience. Just be mindful of its size and weight when transporting and storing it.
