This brushless motor operates on a 74V system, maintaining efficiency even during extended high-load scenarios like desert dune riding. The liquid-cooled design prevents overheating during sustained peak outputs—critical for UAE’s desert climates. A “Crawl Mode” provides precise low-speed control comparable to 250cc petrol bikes. For maximum durability, Surron Dubai recommends quarterly motor inspections when riding in sandy conditions.
How does the Ultra Bee’s battery system perform?
The 74V/60Ah NMC battery delivers 4.44kWh capacity with IP67 waterproofing. Using 21700 cells, it achieves 800+ cycles to 80% capacity and recharges 20–80% in 2.5 hours via 10A fast charging.
Surron Dubai’s testing shows the battery maintains 85% range at 45°C ambient temperatures—essential for Middle Eastern riders. The modular design allows hot-swapping packs in <3 minutes using military-grade XT90S connectors. Advanced BMS systems prevent voltage sag during high-current draws, sustaining 21kW outputs even below 20% charge. For comparison:
| Model | Voltage | Energy | Fast Charge |
|---|---|---|---|
| Light Bee X | 60V | 2.88kWh | 4hrs |
| Ultra Bee | 74V | 4.44kWh | 2.5hrs |
What chassis components enhance off-road capability?
The forged aluminum frame combines 6061-T6 alloy rigidity (210MPa yield strength) with 19kg lightweight construction. Paired with 240mm inverted forks and 85mm progressive rear suspension, it absorbs impacts from 1.5m drops without bottoming out.
Ground clearance of 315mm surpasses most 450cc enduro bikes, while the 1,178mm wheelbase ensures high-speed stability. Surron Dubai technicians emphasize proper sag adjustment (30–35% of travel) for UAE’s mixed terrain. The forged magnesium alloy wheels save 2.3kg compared to standard aluminum rims—critical for reducing unsprung mass in technical sections.
What smart features does the Ultra Bee include?
A 5-inch TFT dashboard provides real-time diagnostics, GPS navigation, and Bluetooth connectivity. Riders can customize power maps, traction control levels, and regenerative braking via the Surron Dubai app (iOS/Android).
The system logs 72 parameters including individual cell voltages and MOSFET temperatures. Anti-theft features include geofencing and biometric ignition. Unlike competitors, the Ultra Bee’s CAN bus system enables true OTA updates—Surron Dubai pushed 14 firmware upgrades in 2024 alone for enhanced ride modes.
