Biktrix Juggernaut Ultra FS Pro 3 MTB

Full Suspension. Full Performance.

The Juggernaut FS sets itself apart with carefully selected high-end components that optimize power, handling, and versatility for trail riding.

Its 1000W Bafang Ultra mid-drive motor delivers superior torque and efficiency by being mounted at the crankset. This central location gives better weight distribution and more natural ride feel compared to hub motors.

The 11-speed SRAM NX/GX drivetrain provides a wide 11-46t gear range to handle everything from steep climbs to fast descents. The additional gear ratios allow you to find the perfect cadence and torque in all situations.

While most competitors offer a single battery option, the Juggernaut FS can be configured with either a 17.5Ah or massive 35Ah 52V battery. The larger 700Wh battery provides over twice the range for backcountry trail and bikepacking adventures. It features high discharge cells, a durable aluminum case, and fast charging.

Suspension is dialed in for stability and control with its adjustable KKE inverted front fork and DNM Burner hydraulic coil shock. The inverted design reduces binding and flex. The coil shock soaks up impacts more smoothly than air-sprung shocks.

Finally, the Juggernaut rolls on high grip 26x4" fat tires or faster 27.5x3" MTB tires depending on your riding style. Wide tires provide more traction in loose terrain while the 27.5" option is nimble and efficient on hardpack.

Every component from the motor and battery to drivetrain and suspension is optimized for technical trail riding. The Juggernaut FS delivers next-level electric mountain bike performance and versatility.
