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
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.
SUSPENSION SYSTEM
All-new custom suspension system
Comprehensively upgraded from the 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.
INTERSECT TR Rear Suspension System
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.
Front 80/100-19 and rear 100/90-18professional off-road wheelset
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.
Enhanced braking system
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.
Newly upgraded primary Drive system
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.
PERFECTION LS BALANCE EVERYWHERE
Does off-roading require traction control to be turned
The ULTRA BEE features a new generation of off-road ASR traction control system (SRTC), that can be used in various off-road scenarios. With three adjustable levels for quick one-button adjustments, combined with a three-level adjustable throttle power curve, it allows for better control of vehicle stability without compromising handling, making you an off-road expert in no time.
SURRON APP connection
Vehicle information, remote viewing, driving trajectories location-based anti-theft, OTA update service feedback, and more… A wealth of features at your fingertips.
*The SURRON APP connection may not be used in certain countries due to regulatory restrictions.
All-new desert brown frame appearance
Meticulously blended to create a unique red desert brown color, with a bright texture that encapsulates the beauty of the mountains and fields, integrating seamlessly with nature
Off-road version
Featuring a professional off-road wheelset with a front 80/100-19 and a rear 100/90-18, the widened rear tire significantly improves grip and stability, enabling the vehicle to maintain excellent traction in various complex road conditions. The high-strength wheelset structure and dense tread texture provide ample confidence for getting out of difficult situations.
All-Terrain Version
Featuring a 90/90-19 front and 120/80-18 rear all-terrain wheelset, this version offers superior lateral support and grip, catering to both commuting on paved roads and off-road riding, providing an exceptionally balanced wheelset configuration. The front rim is 19×2.15, compatible with the Bee 90/90-19 off-road tire; the rear rim is 18×2.50, compatible with the 100/90-18 off-road tire*, fully unleashing its off-road capabilities. It features a slim saddle with a seat height as low as 850mm, a significant 60mm reduction compared to the off-road version.
