Ultra Bee — where electric off-road performance reaches its peak in Sur-Ron’s most powerful, most capable dirt bike to date. For riders who demand maximum speed, extreme torque, and unmatched hill-climbing ability, the Ultra Bee delivers a ride that’s as intense as it is exhilarating. With a 10000W peak motor, 72V lithium battery, and 132-lb reinforced frame, this machine conquers the steepest inclines, deepest mud, and most technical trails with effortless authority—making it the ultimate electric dirt bike for serious off-roaders.

Unlike the agile Light Bee or the balanced Light Bee S , the Ultra Bee is engineered for big-bore performance—featuring a higher-voltage system, beefier suspension, and race-inspired ergonomics that rival gas-powered 450cc motocross bikes. Whether you’re racing friends, tackling mountain trails, or pushing the limits of electric power, the Ultra Bee ensures you do it with silent, emission-free dominance.

Pair it with the street-legal Light Bee X for road use, or compare it to the trail-focused Light Bee S for a lighter alternative.
