Equipped with the all-new second-generation high-peformance mid-mounted motor, the peak power has surged to 21 kw,an increase of over 68% compared to the previous generation! The maximum torgue of the drive wheel has increased by 16%,reaching an astonishing 377ft-lbs, A new Turbo riding mode has been added, allowing acceleration from 0 to 31moh in just 2 seconds! Bursting with power, ready at your fingertips!
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.
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.
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.
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 extendedlifespan, Weighing only 47lbs, the battery pack is easily removable,allowing for convenient charging anytime, anywhere.
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.
Custom gold outer tube with enhanced internal sliding sleeves, providing smooth and silky compression rebound. The initial phase is soft, with greater load capacity in the mid to latter sections. Whether used in forest trails or on racing tracks, it offers stable support and precise handling.
Compression and rebound can be adjusted to adapt to more riding scenarios
External pipe upgrade 7 series aluminum alloy material, the overall strength and rigidity greatly improved
A multi-link rear suspension system, combined with fully adjustable airbag rear shocks and high-strength alloy springs, integrates seamlessly with the overall shape and structure of the vehicle.
The shock absorption performance is tailored to the characteristics of the ULTRA BEE, ensuring that the tires maintain optimal grip at all times.
The widened rear wheel significantly enhances grip and stability, allowing the vehicle to maintain excellent traction across a variety of complex terrains. The high-strength wheelset structure and dense tread patterns provide ample confidence for getting out of tricky situations.
The high-strength motorcycle braking system features a 90% increase in caliper rigidity. The braking feel is light and linear, allowing for precise control with just one finger, ensuring safety for your off-road adventures.
The new carbon fiber core belt has excellent load capacity per unit width, excellent wear resistance and low thermal expansion coefficient, and the ultimate strength is increased by 60%.
The surface of the pulley is coated with tungsten carbide, which is second only to diamond in wear resistance and hardness, greatly improves the strength and life of the pulley.
