ULTRA PERFORMANCE.
Another bold attempt, another milestone breakthrough. Engineered with experience gained from the existing Bee family of electric bikes, as well as racing over the last few years, the all-new Surron Ultra Bee is here to redefine the electric off-road experience.
OUT FROM WITHIN.
Inspired by its successful predecessors, Surron’s new Ultra Bee takes electric performance to a whole new level. Surron’s latest powertrain system is at the heart of this mid-sized powerhouse. The newly-designed platform delivers precision lightweight handling, smooth power output, and integrates Surron’s refined off-road traction control system (SRTC) to help conquer obstacles on your ride.
