What motor specifications define the Ultra Bee?
The Ultra Bee uses a mid-drive 12500W brushless motor with field-oriented control (FOC), achieving 95% efficiency. The liquid-cooled design sustains 21kW peak output for 10-second bursts during climbs. Pro Tip: Regularly check phase wire connections—vibration in desert rides can loosen terminals, causing resistance heat buildup.

Its three-phase sinusoidal controller modulates power through 18 MOSFETs rated 200A continuous. For example, climbing 35° dunes triggers “Torque Boost Mode,” temporarily overriding 250N.m limits. However, repeated use drains the 74V battery 27% faster. Transitional loads are managed via inertial measurement units (IMUs) that adjust regeneration dynamically. Warning: Avoid aftermarket controllers—Surron Dubai’s OEM units have proprietary throttle mapping protecting battery lifespan.
| Motor Type | Peak Power | Efficiency |
|---|---|---|
| Ultra Bee | 21kW | 95% |
| Competitor A | 15kW | 89% |
How does the battery system enhance performance?
The 74V 55Ah LiNMC battery provides 4.07kWh capacity with 2000+ cycle life. Its 15-layer BMS monitors individual cell temperatures, balancing charge/discharge rates during UAE summer rides. Why risk thermal runaway? Surron Dubai implements graphene-enhanced anodes reducing internal resistance by 40% compared to standard packs.
Modular design allows hot-swapping batteries in 90 seconds—ideal for rally events. Charging via 84V 10A charger achieves 80% in 2.5 hours. Real-world testing shows 118km range at 45km/h on Dubai-Al Ain Road. Pro Tip: Store batteries at 30-50% charge if unused for weeks; full charges accelerate electrolyte degradation in 45°C heat.
What terrain capabilities does it offer?
With 270mm ground clearance and 21×2.75” CST tires, the Ultra Bee tackles wadis and dunes effortlessly. The adjustable WP suspension provides 220mm front/210mm rear travel, absorbing impacts at 65km/h. For instance, riders can clear 800mm gaps in Hatta Mountain trails without bottoming out.
Four ride modes (Eco, Trail, Sport, Turbo) adjust torque delivery from 120N.m to 440N.m. The Turbo mode momentarily disables speed governors, though Surron Dubai recommends this only for experienced riders using proper safety gear. Transitioning between surfaces? The tire pressure monitoring system (TPMS) alerts when PSI drops below 18, preventing sand pinch flats.
| Terrain Type | Recommended Mode | Avg Speed |
|---|---|---|
| Dunes | Turbo | 55km/h |
| Rocky | Trail | 35km/h |
Surron Dubai Expert Insight
FAQs
Yes, when configured with mirrors, indicators, and speed restrictors per RTA guidelines. Surron Dubai provides compliance packages including documentation for registration.
How does it handle 50°C temperatures?
The battery pack uses phase-change materials absorbing excess heat, maintaining optimal 25-40°C cell temps during summer rides. Automatic derating occurs if sensors detect critical thresholds.
