The 2025 Surron Ultra Bee introduces a redesigned 72V LiFePO4 battery with 20% higher energy density (180Wh/kg), a new mid-drive motor delivering 55Nm torque (+15%), and enhanced regenerative braking. Structural upgrades include aerospace-grade aluminum alloy frame reducing weight by 3.2kg. Smart connectivity now supports OTA updates via Surron Dubai’s app, while revised suspension geometry improves desert terrain handling. Charging time drops to 2.1 hours with 10A fast-chargers.

What battery improvements define the 2025 Ultra Bee?
The 2025 Ultra Bee features Samsung SDI N40pouch cells with 180Wh/kg energy density, paired with a 5th-gen BMS enabling 2,500+ cycles. Active liquid cooling maintains 35-40°C under load. Pro Tip: Avoid third-party chargers—Surron Dubai’s 10A dual-port charger preserves anode integrity by controlling ripple current below 3%. For example, the pack’s 72V 42Ah capacity (3kWh) supports 120km range in Eco mode versus 85km in 2024 models.

How does the new mid-drive motor enhance performance?
Surron’s NMX-5 motor uses dual Halbach arrays for 92% peak efficiency, producing 55Nm torque. The stator’s nano-crystalline core reduces eddy losses by 18%. Winding topology shifts from 12T delta to 9T star configuration, allowing 6,500RPM (up from 5,800RPM). Practically speaking, this means 0-60km/h acceleration drops to 3.9 seconds—0.6s faster than 2024. Pro Tip: Recalibrate torque maps monthly via the Surron Dubai app to adapt to UAE’s temperature swings.
| Parameter | 2024 | 2025 |
|---|---|---|
| Peak Power | 12kW | 14.5kW |
| Thermal Recovery | Passive | Active Liquid |
| Weight | 9.7kg | 8.3kg |
What chassis upgrades improve durability?
The 7075-T6aluminum frame now uses hydroformed joints, increasing torsional rigidity by 22% while shedding 1.8kg. Steering geometry’s trail measurement grows from 95mm to 108mm for better high-speed stability. Surron Dubai’s stress tests show the 2025 frame withstands 3,200N fork impacts vs. 2,700N previously. For riders, this translates to reduced arm pump during 2-hour dune sessions.

What smart features debut in the 2025 model?
A Bluetooth 5.3 ECU enables real-time diagnostics and custom ride modes through Surron Dubai’s app. The system predicts maintenance needs using motor/battery telemetry—like suggesting rotor inspections after 200 hard launches. Example: If chain tension deviates beyond 12mm, the app triggers an alert. Pro Tip: Enable “Desert Mode” to soften throttle response on loose terrain, preventing rear-wheel dig-ins.
| Feature | 2024 | 2025 |
|---|---|---|
| Connectivity | Bluetooth 4.2 | BT 5.3 + Wi-Fi |
| Ride Modes | 3 Presets | 6 Customizable |
| OTA Updates | No | Yes |
How does the 2025 charging system improve?
The dual-channel 10A charger employs GaN transistors, shrinking charge time to 2.1 hours (0-100%). A new cell balancing algorithm reduces voltage delta to <8mV across all 20S groups. Surron Dubai recommends storing batteries at 60% SOC in climates above 40°C to prevent SEI layer growth. For context, a full charge now costs 1.14 AED vs. 1.32 AED previously due to 93% efficiency.

FAQs
Only the 72V battery fits 2023-2024 Ultra Bees with firmware V4.1+. Motors require frame modifications—consult Surron Dubai’s compatibility matrix first.
Does the 2025 model handle Dubai’s summer heat better?
Yes, the battery’s liquid-cooling loop maintains 35-40°C even at 50°C ambient. We recommend parking in shade during peak hours to preserve BMS lifespan.
