Bonnell 775 MX: Lightweight E-Moto Performance Without the Bulk
Downhill Bike Agility Meets Real Electric Dirt Bike Power
The Bonnell 775 MX blends downhill mountain bike maneuverability with legitimate electric dirt bike performance. At approximately 75 lbs, it stays light and responsive while delivering up to 6,000W from the CYC X1 Pro Gen 4 powertrain.
A 65V 1,300Wh Samsung 50S battery, integrated torque sensing, full downhill suspension, premium Magura brakes, and app-based tuning create an e-moto that can be ridden smoothly with pedal assist or unleashed with throttle when it's time to move.
Off-road use only. All electric dirt bikes sold by Lithium Powersports are intended for off-road use only unless otherwise noted. The buyer is responsible for complying with local, state, and federal laws. Ride responsibly and wear proper safety gear.
Key Features
6,000W Peak Power
CYC X1 Pro Gen 4 power gives the 775 MX serious performance while retaining the lightweight feel that defines the platform.
65V / 1,300Wh Battery
Samsung 50S cells provide a high-output battery package designed around both performance and usable riding range.
Only ~75 lbs
A lightweight chassis keeps the bike agile on technical terrain, jumps, tight trails, and changing lines.
Suntour DH Suspension
RUX 38 RC+ fork and Voro coil rear shock give the 775 MX true downhill-level suspension capability.
Magura MT5 Brakes
Four-piston hydraulic braking with large rotors provides serious stopping power for aggressive terrain.
Torque Sensor + App Tuning
Integrated torque sensing and Bonnell Ride Control let riders tailor power, throttle response, and assist behavior.
CYC X1 Pro Gen 4 Powertrain
The 775 MX is powered by the CYC X1 Pro Gen 4, delivering up to 6,000W of peak output and approximately 280 Nm of torque.
Unlike many throttle-only electric motorcycles, the 775 MX maintains an integrated torque-sensing pedal system. Riders can cruise smoothly under pedal assist or access full throttle performance when maximum output is wanted.
