Biktrix Juggernaut Ultra FS Pro 2 Review: A Force to be Reckoned With

The Biktrix Juggernaut Ultra FS Pro 2 stakes its claim as a robust, full-suspension fat tire e-bike designed for adventurers seeking unparalleled power and comfort. Priced at $4199, this machine is built to conquer. At its heart lies the formidable 1000W Bafang Ultra M620 mid-drive motor, delivering an astounding 160 Nm of torque – more than enough to tackle "extreme hills" with ease. Paired with a 52V 17Ah (884 Wh) battery, the Juggernaut promises ample power for extended off-road excursions, while its ability to accommodate a second battery expands its range capabilities even further. The manufacturer proudly positions it as "the best-built full-suspension fat tire eBike available," a bold statement that speaks to its premium aspirations.

Performance & Ride Quality

On the trails, the Juggernaut Ultra FS Pro 2 truly shines. The Bafang Ultra motor, known for its sheer strength, provides on-demand throttle power and smooth, powerful pedal assist thanks to its integrated cadence and torque sensors. This translates to an intuitive and responsive ride, allowing cyclists to navigate demanding terrain without compromising effort. The drivetrain, featuring an 11-speed SRAM NX trigger shifter and an 11-42t cassette, ensures a wide range of gearing for optimal power delivery across varied gradients. Braking is handled by Biktrix's dual-piston hydraulic disc brakes with 180mm rotors, offering reliable stopping power with integrated brake cutoffs for enhanced safety. With a substantial 265 lb load capacity, this e-bike is not just for solo adventures but can also handle cargo or towing, as one reviewer noted when effortlessly pulling a 150lb trailer up steep hills.

Comfort, Features & Build

Comfort is paramount with the Juggernaut Ultra FS Pro 2, featuring a full-suspension setup comprising an RST Renegade TNL fork with 100mm travel and a Rockshox Monarch RL rear suspension with 51mm travel. These components, combined with large 26x4" fat tires, soak up bumps and uneven terrain, providing a "gliding on air" sensation that many riders appreciate. The bike's build quality, featuring a durable 6061 aluminum frame and integrated headlight, is generally praised by users. While its 71.9 lb weight (without battery) is considerable, it speaks to its robust construction. Minor critiques include the motor's discernible noise and the absence of a gear indicator on the SRAM shifter. However, these are small trade-offs for an e-bike that delivers such a high level of performance, capability, and comfort, making it an excellent choice for serious off-road enthusiasts and those needing a high-power utility bike.
