Why Choose Fission Cycles Hellbender 750W Ultra Drive Electric Bike

The Hellbender is not just an e-bike; it is a statement of intent. While other mountain e-bikes compromise on power or durability, the Hellbender delivers a premium, no-compromise build that serious riders crave. The Bafang Ultra-Drive is widely regarded as the gold standard for off-road e-bikes, offering a low center of gravity and a gear-driven design that delivers unmatched climbing torque without the hub-motor drag. Paired with the LG 48V/20 AH battery, you get a reliable, long-lasting power source that keeps the trail alive long after lesser bikes have run out of juice.

We understand that off-road riding demands resilience. That is why we spec’d the Hellbender with a 6061 Aluminum frame, 4-piston hydraulic brakes, and a dual-suspension setup featuring a Fastace air shock and EXSHO inverted fork. This isn’t a commuter bike with knobby tires; it’s a purpose-built trail destroyer. Plus, with FREE SHIPPING to the lower 48 states (a $250 value), you can invest your savings into gear for your next epic ride. Choose the Fission Cycles Hellbender and experience the pinnacle of electric mountain biking.

Frequently Asked Questions

The Hellbender is shipped in a box and requires partial assembly. Typically, you will need to attach the front wheel, handlebars, pedals, and seat post. Basic tools are included. We recommend having a bike mechanic perform the final check to ensure the brakes, suspension, and torque sensor are correctly adjusted for optimal performance.
The Hellbender is designed for riders approximately 5'4" to 6'4" tall, with a maximum weight capacity of 300 lbs. The 26 x 4.0" fat tires and adjustable suspension provide a stable, comfortable ride for a wide range of body types. Always verify your inseam and reach before purchasing to ensure a proper fit.
The LG battery provides an average range of up to 45 miles under typical conditions. Actual range depends on factors like rider weight, terrain, pedal assist level, throttle use, and tire pressure. On steep, technical trails with high assist, range may decrease. The LCD display helps you monitor battery level in real time.
Keep the motor clean and dry; avoid pressure washing directly at the motor seals. Lubricate the chain regularly and check all bolts for tightness. The Fastace rear air shock and EXSHO inverted fork require periodic air pressure checks and seal inspections. Refer to the user manual for specific service intervals.
We offer a 30-day return window from delivery for unused, undamaged bikes. Returns are subject to a restocking fee and must be shipped back in original packaging. The Hellbender includes a manufacturer’s warranty covering the frame and major components. For full terms, contact our support team before purchasing.
Yes, the Hellbender is built for aggressive off-road trails. Its 750W Ultra-Drive motor, 4.0" fat tires, and full suspension provide traction and stability on loose terrain. However, it is not a silent electric bike; the motor and tires produce noise. For stealth hunting, consider models with quieter tires or a hub motor.
The Hellbender is a Class II & III eBike, offering both throttle-only and pedal-assist modes. You can use the thumb throttle for instant power without pedaling, or choose from 5 levels of pedal assist. The torque sensor provides a natural, responsive feel when pedaling. Top speed is 28 MPH in assist mode.
The Hellbender weighs approximately 100 lbs, making it one of the heavier e-MTBs due to its robust frame, motor, and battery. Transporting it typically requires a heavy-duty bike rack or a pickup truck. The removable LG battery helps reduce weight when lifting, but the bike itself is not lightweight.
