The Bonnell 775 MX is a new breed of lightweight electric dirt bike, designed to blur the line between a downhill mountain bike and a full-powered e-moto. Weighing in at just 75 lbs and packing serious torque, this is your off-road sidekick for everything from technical singletrack to all-day exploration. With a rugged chromoly frame, premium suspension, and 6,000W peak output, the 775 MX delivers all the agility of a mountain bike—without giving up moto-grade performance.

Whether you're pedaling on eco mode or ripping on full throttle, the 775 adapts to your terrain, your riding style, and your ambition.
