Ultra bee

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.




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.

A refined, race-inspired braking system will boost stopping power on the trails, while the unique TR rear suspension and new front suspension will inspire you to go faster, jump farther and ride with confidence.
