POWER SYSTEM
Hairpin motor x MTPA/MTPV
Hairpin Motor
The second-generation motor of the ULTRA BEE serves as a powerful power core, utilizing a new Hairpin winding technology that significantly increases the motor’s filing factor,resulting in higher efficiency and improved heat dissipation.
Additionally, the embedded permanent magnets in the rotor maximize the magnetic reluctance torque at low speeds, enhancing torque density, with better weak magnetic performance, the motor achieves higher speeds, with a maximum rotational speed of 7.000 rpm, and maintains peak power output from 2,000 rpm to 7,000 rpm.
MTPA/MTPV Controller
Independently developed and tuned by SURRON, this controller employs a brand-new MTPA/MTPV control strategy further optimizing the internal structure and circuit layout to fully leverage the performance advantages of the HairPin winding embedded permanent magnet motor.
Traction Control System
The ASR off-road traction control system can be used in various of-road scenarios, featuring three selectable levels for quick switching, minimizing rear wheel slip interference to the greatest extent, combined with multi-level adjustable energy recovery and a three-level adjustable throttle curve, you can determine how you want to rider.
Eco/Daily/Sports/Crawl/Reverse + “Turbo” 6 power modes can be switched at any time, allowing your Jifeng to be suitable for all weather conditions.
BATTERY SAFETY
High-performance Battery Pack
The all-new 74V60Ah lithium battery pack is equipped with a safe and efficient
battery management module, delivering abundant and stable power.
Featuring distributed temperature sensors and a microcontroller with CAN
communication protocol, it ensures high power load capacity and extended
lifespan, Weighing only 47lbs, the battery pack is easily removable,allowing for convenient charging anytime, anywhere.
Balance is Perfection
The ULTRA BEE adheres to the sURRoN’s design philosophy of “Balance ls
Perfection”,The frame is made of forged aluminum alloy, tailored to the ULTRA BEE’s dedicated power system. The front-to-rear weight ratio is 50:50.The whole bike weighs merely 195lbs,making it easily liftable,even with bare hands.
The overall Human-to-Machine interface and flexible riding characteristics
configuration allow riders to find their personal favorite between daily commuting comfort and off-road capability,achieving a seamless harmony from inside out.
HIGH-PERFORMANCE MOTOR
FOC INTELLIGENT CONTROLLER
Refresh and upgrade, building momentum
The self-developed power platform has been carried by the first generation of light Bee and has been verified by the global market for 8 years.The 2025 Light Bee power system has been fully upgraded, and after high-intensity testing by top riders at home and abroad, and continuous optimization and tuning, the fit degree of the power system has reached an ideal state, and many key parameters such as power, torque, and acceleration have been greatly improved, which can adapt to more changeable and complex riding scenarios.
High Performance Mid-motor
The powerful power heart has witnessed the off-road road of tens of thousands of Light Bee owners. After years of iterative optimization,reliability and stability have reached a new level With a peak power of 8000W, it can bring the maximum torque of 196.2 ft-lbs at wheel and reach a top speed of 46.6 mph. The maximum motor speed exceeds 5500rpm and can maintain peak power output from 1500rpm to 5000rpm.
The 38UH high-grade permanent magnet material can withstand high temperatures up to180℃, and is suitable for harsher use conditions and fierce riding environments
FOC Smart Controller
The newly upgraded internal hardware structure is optimized for the high-performance motor of Light Bee, making the three-phase current layout more uniform, greatly improving the current passing capacity.After hundreds of verification sunder different scenarios, it ensures continuous and stable power output; The continuously improved the algorithm program to further understand the rider’s intention, and the whole bike control is more accurate and delicate.
