🔥 This is the Bonnell 775MX — a category-defying electric hybrid built for riders who want elite motocross power in a nimble, 75 lb mountain bike chassis. It’s the ultimate ‘stealth’ machine, designed to dominate technical trails and steep climbs that would stall a standard e-bike.

 

Key Features & Highlights

  • Massive Power-to-Weight: A mid-drive motor pumping out 6,000W of peak power and a staggering 280 Nm of torque, delivering instant ‘pop’ and acceleration.

  • High-Performance 65V System: Powered by a 1300Wh battery using premium Samsung 50S cells, optimized for high discharge and aggressive riding.

  • Hybrid Chassis: A rugged 4130 Chromoly steel front triangle paired with 6061 forged aluminum chainstays for the perfect balance of flex and durability.

  • Pro-Level Suspension: Full downhill-spec suspension with a Suntour Rux 38 dual-crown fork (200mm travel) and a Voro Coil rear shock (170mm travel).

  • Elite Braking: Magura MT5 4-piston hydraulic brakes with massive 220mm/203mm floating rotors for motorcycle-grade stopping power.

  • Mullet Wheel Setup: Runs a 29″ front wheel for rolling over obstacles and a 27.5″ rear wheel for snappy handling and better torque.

  • Silent Stealth: Features a custom sprag clutch rear hub for instant engagement and silent coasting—no loud clicking or motor whine.

Performance & Ride Feel

  • Top Speed: Approximately 37–40 mph (Stock configuration).

  • Range: Typically 12–37 miles depending on terrain, assist level, and throttle usage.

  • Charging Time: Rapid charging in under 4 hours with the included 5A charger.

Why the Bonnell 775MX stands out The 775MX occupies the ‘Goldilocks’ zone between a mountain bike and a dirt bike. At just 75 lbs, it is nearly 50 lbs lighter than a Sur-Ron, making it incredibly flickable on tight singletrack. It isn’t a bulky motorcycle; it’s a high-powered precision tool that allows you to ride harder, climb steeper, and stay under the radar.

Frequently Asked Questions

The Bonnell 775 MX is backed by a comprehensive 24-month (2-year) limited warranty on the chassis, including the chromoly front triangle and aluminum swingarm.

The high-performance electric power system—which includes the CYC motor, motor controller, and 72V battery pack—is covered for 12 months (or 500 hours of use, whichever comes first). Additionally, premium third-party components like your Suntour suspension carry their own 12-month manufacturer warranties.

The Bonnell 775 MX occupies a unique “Ultra-Light” category between a Downhill MTB and a full-sized E-Moto. While competitors like the Sur-Ron Light Bee or Talaria Sting lean into motorcycle-heavy builds, the 775 MX prioritizes agility and a “flickable” feel.

  • Extreme Power-to-Weight: At just 75 lbs, the 775 MX is nearly 40 lbs lighter than its closest competitors. Combined with a peak 6,000W output, it offers an acceleration curve that rivals modified e-motos.

  • Mountain Bike Agility: Because it uses high-end MTB suspension (Suntour Rux 38) and brakes (Magura MT5), it handles technical single-track and tight switchbacks with a precision that heavier bikes can’t match.

  • Torque Dominance: The mid-drive CYC X1 Pro system delivers a staggering 280Nm of torque at the crank, outclassing stock competitors for vertical climbs and “out-of-the-hole” punch.

  • Realistic Speed: While ships restricted, the unlocked 775 MX typically tops out around 37–40 mph (gearing dependent). It’s designed for explosive trail performance rather than high-speed road cruising.

The Bonnell 775 MX features a professional-grade Hybrid Chassis specifically designed to handle the extreme torque of its $6,000W$ motor.

  • 4130 Chromoly Front Triangle: Unlike standard “mild steel,” we use 4130 Chromoly—an alloy known in the aerospace and racing industries for its incredible strength-to-weight ratio. It is finished with an anti-rust ED (Electrophoretic Deposition) coating for lifetime durability against the elements.

  • 6061 Forged Aluminum Rear End: The chainstays and seatstays are crafted from forged 6061 aluminum to keep the rear end light and responsive, featuring a progressive single-pivot linkage for consistent traction.

  • Pro-Level Suspension: Equipped with a massive 200mm Suntour Rux 38 RC+ dual-crown fork and a Suntour Voro Coil rear shock (170mm travel).5 This setup is custom-tuned specifically for the weight and speed of the MX, offering five positions of low-speed compression adjustment.

  • Precision Braking: To manage high-speed off-road descents, the bike uses Magura MT5 4-piston hydraulic brakes paired with oversized 220mm front and 203mm rear MDR-P floating rotors for fade-free stopping power.

  • Maintenance-First Design: Every pivot point uses full-complement stainless steel sealed bearings packed with marine-grade grease, ensuring the bike stays quiet and smooth even after countless muddy sessions.

Absolutely. The Bonnell 775 MX is engineered with a dual-personality power delivery that makes it accessible for those just starting their off-road journey while remaining a “beast” for veteran riders.

  • For Beginners: The bike is remarkably lightweight (75 lbs), making it much easier to manuever than a traditional 200 lb gas dirt bike. It features a programmable speed limiter and multiple power modes, allowing new riders to build confidence at lower speeds before “unlocking” the full potential of the motor. The intuitive twist-and-go throttle eliminates the complexity of gears or a clutch.

  • For Experienced Riders: Once the CYC X1 Pro Gen 4 motor is set to “Race Mode,” the 775 MX delivers 280Nm of instantaneous torque. This allows seasoned pros to tackle vertical climbs and technical logs that would stall a standard e-bike. The pro-spec Suntour and Magura components provide the adjustability and “trail-feel” that high-level riders demand for aggressive downhill and jump-line sessions.

  • The Hybrid Advantage: Its slim, mountain-bike-inspired ergonomics provide a familiar feel for cyclists, while the 200mm of dual-crown travel offers the stability required for high-speed moto-style terrain.

The Bonnell 775 MX is equipped with a high-capacity 1,300Wh (65V/20Ah) A65-series battery pack engineered for maximum energy density. Because the bike is significantly lighter than its competitors (only 75 lbs), it achieves impressive efficiency levels.

  • Typical Range: Depending on terrain and riding style, expect 12 to 37 miles of trail exploration.

    • Hard Enduro/Full Throttle: ~12–15 miles of aggressive climbing and high-speed runs.

    • Mixed Trail Riding: ~20–28 miles in standard power modes.

    • Efficiency Mode: Up to 37+ miles when utilizing the integrated torque sensor and pedal-assist for casual flow trails.

  • Rapid Charging: Using the included 5A Smart Charger, a full recharge from 0% to 100% takes under 4 hours. The intelligent BMS (Battery Management System) allows for “topping off” the battery during lunch breaks without damaging cell longevity.

  • Swappable Convenience: The battery is designed for quick removal, allowing you to swap in a fresh pack in seconds to keep the session going all day.
