Lightweight, high-performance off-road brakes

Lightweight and sensitive braking feel

With patented parking system

Easy one-handed locking of wheels.

Lightweight forged aluminum frame

The compact structure allows for a lower and more focused center of gravity and mass, providing the user with a precise and controlled operating experience.

Independently developed INTERSECT TR rear suspension system

Carefully designed for the high-intensity off-road of Extreme Bee

High performance outside and inside

Based on the fourth-generation power platform, the newly designed middle-weight off-road model, styling design inheritance iteration, every detail exudes high performance, agile and easy handling, with sur-ron unique off-road type electronic control system control logic tuning, significantly improve off-road performance at the same time, lower the riding threshold, racing-grade brake system, providing more possibilities for the extreme state, SUR- RON technology independent research and development INTERSECT TR rear suspension system, higher progressive rate, smoother progressive curve, soft with toughness, so that the extreme bee inside and outside both extreme performance.

Ultimate Balance

With SUR-RON's design concept of balance is the ultimate, the frame is forged with aluminum alloy, matched with an exclusive power system, 50:50 front and rear weight distribution, the whole bike is only 85kg, and can even be picked up with bare hands, the whole bike man-machine, configuration settings, taking into account the daily riding comfort and off-road capabilities, internal and external balance to obtain a very high balance.

74V55AH

High-performance lithium battery pack

The new structure of the battery (4070wh) brings higher power density and up to 1500 cycles of battery life, and achieves lower discharge temperature rise to improve the reliability and sustained discharge capacity of the battery, and the battery pack weighing 20.5kg achieves an industry-leading capacity density of 200wh/kg.

After 1500 normal charging cycles, the battery capacity can still reach 80%.

ULTRA BEE Details

Must off-road traction control be turned off?

With a new generation of off-road ASR traction control system (SRTC) used in various off-road scenarios, 3 levels of gears can be quickly adjusted at the touch of a button to better control the stability of the vehicle without affecting the handling, allowing you to easily become a drift master.

Rear tail light and license plate holder

Power Mode

Selector switch

Economy / Daily / Sport / Reverse

4 power modes can be selected, clever button layout, even in intense driving can be fast and accurate operation, the addition of reverse gear makes off-road riding more convenient, do not worry about the effort to get out of trouble.

Customized fully adjustable shock system

The ULTA bee uses a flexible directional limit, which can protect the shock system and wheel system better in case of a crash.

The charger can be carried with the bike to enjoy the ride.

Under the saddle, there is a special storage space for the charger, and the air ducts are reserved for heat dissipation to support the built-in work of the charger.

SUR-RON networking system

Vehicle information, remote viewing, driving trajectory, positioning anti-theft, OTA updates, etc., a wealth of functions at your fingertips.

The charger can work safely in the storage compartment, but the built-in charging is not recommended when the temperature is higher than 35℃ or in a small closed space, because it may cause the charging time to grow due to less efficient heat dissipation than the external space.

New power system combination

Ultra bee dedicated power system, a combination of the great success and integration, fully isolated electrical architecture, to avoid interference between high and low voltage circuit, power output balanced ratio, peak output 12.5kw, drive wheel maximum output 440N.m torque, and 74V55AH battery to form the best partner, delicate operation, flexible and agile, extreme driving is also reliable, to achieve a number of all-round performance.
