Description
High-Torque Utility Engineering. Unrivaled Backcountry Power.
When hauling heavy gear through thick timber, climbing steep mountain fire roads, or navigating deep sand and snow, standard e-bike setups can stall out or overheat under the pressure. The Fission Hellbender Max is built specifically to handle those high-demand situations, acting as a dependable mechanical pack mule that handles the toughest terrain without hesitation.
At the heart of this machine is the Bafang 1000W Ultra-Drive mid-drive motor, pumping out a staggering 160 N·m of torque. Combined with an integrated, high-precision torque sensor, the system reads your pedaling input instantly and delivers smooth, predictive power right when you need it most. Built onto a reinforced 6061 aluminum chassis and wrapped in authentic Mossy Oak® camouflage, it serves as a quiet, capable vehicle designed for hunters, land managers, and off-road adventurers who refuse to let landscapes dictate their boundaries.
Technical Highlights
-
Bafang Ultra-Drive Powerhouse: Produces immense low-end torque to pull trailers up steep grades, clear technical obstacles, and flatten demanding elevation gains.
-
DYISLAND™ Quad-Piston Safety Braking: Outfitted with specialized DYISLAND LD4X-300 4-piston calipers running thick-gauge, high-heat dissipation rotors and oversized MT600 sintered pads. The matching LDN levers feature an integrated electronic sensor that instantly cuts motor power the millisecond you pull the brakes.
-
SRAM NX 1×11 Drivetrain with X-ACTUATION™: Features a uniform, precise cable-pull ratio across the entire gear range to eliminate indexing lag, ghost shifting, and chain slap under heavy motor loads.
-
Bafang DP C18.U 4.2 Color Cockpit: A high-contrast, center-mounted matrix display giving you real-time data tracking (voltage, wattage output, and trip metrics) alongside integrated ambient light sensing and a hidden mobile device charging port.
-
Inverted Air Suspension Architecture: The EXSHO inverted front air fork and Fastace piggyback rear air shock provide high structural rigidity and smooth, stiction-free travel to absorb jarring trail impacts under load.
