Surron Ultra Bee
Unparalleled Off-Road Adventures
Elevate your off-road riding experience with the Surron Ultra Bee, a cutting-edge electric dirt bike that combines top-tier performance with a rugged yet sleek design. Central to the Ultra Bee's power is Surron's 4th-generation powertrain, housed within a meticulously crafted aluminum alloy chassis.
Drawing from the success of previous models, the Ultra Bee pushes the boundaries of electric biking, delivering exceptional performance. Its advanced powertrain ensures precise control and seamless power delivery, enhanced by Surron’s off-road traction control system (SRTC), designed to conquer even the most challenging terrains with ease.
The Ultra Bee isn't just about power. It also features a race-inspired braking system, providing superior stopping power on rough trails. The combination of the unique TR rear suspension and an innovative front suspension system allows riders to test their limits, whether increasing speed, taking on jumps, or boosting their overall confidence.
Engineered with insights from Surron's years of racing expertise, the Ultra Bee features an optimized braking system that delivers fast and responsive braking. A special parking system allows riders to lock the wheels effortlessly with a single hand.
Balancing innovation with practicality, the Ultra Bee is designed with the philosophy of "Balancing On the Cutting Edge," ensuring optimal performance for both daily commuting and trail adventures. Its high-performance lithium-ion battery (4070Wh) offers unmatched power density and extended life, maintaining reliability with a low discharge temperature for consistent energy output.
One of the standout features of the Ultra Bee is the Surron Traction Control System (SRTC), which allows for multiple off-road traction settings at the touch of a button, adapting easily to various terrain conditions.
Riders have the flexibility to choose from four distinct modes: ECO, DAILY, SPORT, and Reverse—all accessible through intuitive switches. The Reverse Mode has been upgraded, providing greater assurance in tricky situations and eliminating the fear of getting stuck on tough trails.
With 240mm of travel, the fully adjustable suspension guarantees safety and comfort across different terrains. The uniquely designed chassis provides added protection against damage during falls.
For added convenience, the Ultra Bee includes a hidden compartment under the seat for storing accessories. It also comes with a 220V charger and a 110V USA adapter.
Powered by Surron's 4th-generation drivetrain, the Ultra Bee uses a 74V/55Ah battery pack paired with a 12.5KW drivetrain delivering an astonishing 440N.m of torque. This makes it a high-speed companion on the track or trail, pushing riders to the extreme.
The Surron Ultra Bee represents the pinnacle of innovation, performance, and adventure, ready to transform your off-road biking experience.
This version is the European street-legal model, equipped with mirrors, brake lights, a license plate holder, high/low beams, turn signals, and a speedometer. Buyers should verify street legality in their region.
