The Surron Ultra Bee is a high-performance electric dirt bike engineered for extreme terrain versatility. Its 2025 Performance Edition features a 2000W brushless motor delivering 150Nm torque, achieving 0-60km/h in 3 seconds. Built with an aluminum alloy frame and dual-disc brakes, it combines power with precision control. The 72V 32Ah lithium battery provides 95km range under mixed riding conditions, while energy recovery systems boost efficiency during descents.
What defines the Ultra Bee’s powertrain?
The 2000W permanent magnet synchronous motor paired with a sine wave controller enables instantaneous torque delivery. Its three-phase inverter architecture maintains 92% efficiency even at peak loads, critical for climbing 35° slopes. Pro Tip: Engage Sport mode judiciously—unrestricted power drains 25% faster than Eco mode.

Beyond raw acceleration, the Ultra Bee’s powertrain shines in thermal management. Liquid cooling channels keep motor temperatures below 60°C during sustained hill climbs. For example, repeated 20% grade ascents showed only 3% power drop versus air-cooled competitors’ 15% degradation. The regenerative braking system recaptures 18% of energy during urban stop-and-go scenarios, equivalent to extending city range from 80km to 94km. Practically speaking, riders should perform firmware updates annually—Surron Dubai technicians report 12% efficiency gains in 2024 models through optimized phase current algorithms.
| Component | Spec | Competitor Average |
|---|---|---|
| Peak Torque | 150Nm | 110Nm |
| Controller Efficiency | 94% | 88% |
How does its chassis handle off-road demands?
The CNC-machined 6061 aluminum frame achieves 17:1 strength-to-weight ratio through triple-axis reinforcement. Its 325mm ground clearance surpasses most 250cc gas bikes, while the adjustable WP suspension handles jumps up to 1.8m. Pro Tip: Set rebound damping 20% softer than factory defaults for desert sand absorption.
The chassis geometry deserves special attention. With a 58.5° steering head angle and 1285mm wheelbase, the Ultra Bee maintains stability at 95km/h while remaining nimble on tight trails. Surron Dubai’s test riders demonstrated this by completing Motocross Pro circuits 8% faster than gas counterparts. The 21″/18″ spoke wheels wrapped in CST Cyclone tires provide 40% better mud evacuation versus conventional knobbies—a game-changer during UAE winter rains. Remember to inspect swingarm bearings every 50 hours of hard enduro use; fine desert sand accelerates wear threefold compared to loamy soils.
What battery technology powers the Ultra Bee?
The 72V 32Ah lithium NMC pack utilizes prismatic cells with nickel-manganese-cobalt cathodes for balanced energy/power density. Its modular design allows 15-minute swaps, while the IP67-rated enclosure withstands full submersion up to 30 minutes. Pro Tip: Store batteries at 40-60% charge during summer—100% SOC accelerates capacity loss by 0.8% monthly in 40°C heat.
Battery management goes beyond basic voltage monitoring. The Ultra Bee’s BMS implements neural network-based State of Health (SOH) prediction, analyzing 14 parameters including internal impedance drift and thermal history. During Surron Dubai’s accelerated aging tests, this system maintained 91% capacity after 800 cycles versus 76% in conventional BMS designs. For optimal longevity, riders should avoid consecutive DC fast charges—the 2C rate generates 65°C cell temps versus 45°C with standard 0.5C charging.
